TESORO REFINING & MARKETING COMPANY LLC v.
CITY OF CARSON
S289952

Opinion of the Court by Guerrero, C. J.

The Government Claims Act (GCA; Gov. Code, § 810 et
1
seq.) establishes a standardized procedure for bringing “all
claims for money or damages against local public entities.”
(§ 905.) In McWilliams v. City of Long Beach (2013) 56 Cal.4th
613, 619–629 (McWilliams), we held that the GCA applies to
claims for tax refunds against local government entities. This
case requires us to decide whether a local government entity
may require a person seeking a tax refund to first comply with
a local administrative review procedure before submitting a
claim to the government entity pursuant to the GCA.
We conclude that a local government entity cannot,
consistent with the GCA, require a person to comply with such
a procedure as a precondition to submitting a tax refund claim.
A local law that conflicts with state law is preempted and may
not be enforced. (Chevron U.S.A. Inc. v. County of Monterey
(2023) 15 Cal.5th 135, 142 (Chevron U.S.A.).) A conflict arises
where the Legislature intends state law to occupy the entire
field on a certain subject, and the local law regulates in the area
occupied by state law. (See O’Connell v. City of Stockton (2007)
41 Cal.4th 1061, 1068 (O’Connell).) The history, text and
structure of the GCA — as well as this court’s own precedents —

1
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

establish that the Legislature intended the GCA to occupy the
entire field concerning presentation requirements for money
and damages claims against local government entities. (See
Volkswagen Pacific, Inc. v. City of Los Angeles (1972) 7 Cal.3d
48, 62, fn. 7 (Volkswagen Pacific) [“the filing of claims for money
or damages against California government units is an area of
statewide concern in which the Legislature has occupied the
entire field”].)
Here, the City of Carson (City) adopted mandatory
administrative review procedures for persons seeking a refund
of the City’s oil industry business license tax. Section 63515 of
the Carson Municipal Code2 requires a person seeking a refund
to file a written “request” with the City’s finance director.
Section 63523 permits the taxpayer, if dissatisfied with the
finance director’s decision, to file an appeal with the city
manager. This procedure — filing a refund request and
subsequent appeal with the City for its consideration — is
simply a way to present a claim which differs from that specified
in the GCA. Because sections 63515 and 63523 of the Municipal
Code impose presentation requirements on persons seeking a
tax refund beyond those established by the GCA, they encroach
upon the field occupied and are therefore preempted.
This conclusion is consistent with the specific history and
purposes of the GCA. In enacting the GCA, the Legislature
sought to address the “conflicting” requirements among public
entities throughout the state for presenting claims for damages
or other monetary demands. (DiCampli-Mintz v. County of

TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

Santa Clara (2012) 55 Cal.4th 983, 993.) Requiring a taxpayer
to exhaust local administrative review procedures in addition to
the GCA’s procedures would frustrate the Legislature’s primary
purpose in enacting “uniform procedures” for the presentation
of such claims. (DiCampli-Mintz, at p. 993.)
In this case, Tesoro Refining & Marketing Company LLC
and Tesoro Logistics Operations LLC (collectively, Tesoro) filed
a lawsuit for recovery of taxes paid after filing an unsuccessful
claim with the City pursuant to the GCA. The City successfully
demurred to Tesoro’s complaint on the ground that Tesoro failed
to exhaust the City’s administrative review procedures. The
Court of Appeal affirmed, rejecting Tesoro’s argument that the
GCA preempted the review procedures. Because this holding
was in error, we reverse.
I. FACTUAL AND PROCEDURAL BACKGROUND
A. The Tax Assessment and Tesoro’s Claim for a
Refund
In 2017, voters in the City approved an ordinance known
as the Oil Industry Business License Tax (the Ordinance),
codified in article VI, chapter 3.5 of the City’s Municipal Code.
(See Mun. Code, §§ 63501–63526.) The Ordinance requires all
persons engaged “in the business of operating an oil refinery or
facility that stores petroleum products” to pay a quarterly
“business license tax” equaling “one-quarter (1/4) percent of
gross receipts of any such business conducted within the City.”
(Mun. Code, § 63505.) The Ordinance also establishes a
procedure for taxpayers to request a refund, under which the
taxpayer must file a request with the City’s finance director.
(Mun. Code, § 63515.) If unsatisfied with the result, the

3
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

taxpayer may appeal the director’s decision to the city manager.
(Id., § 63523.)
Tesoro operates an oil refinery within the City’s
jurisdiction. Following an audit, the City determined that
Tesoro had underpaid its business license tax for the period of
December 2017 through June 2018 and issued a notice of tax
deficiency. Tesoro elected to pay the assessed deficiency under
protest. It then filed a claim with the City clerk for a refund of
the deficiency payment. Tesoro contended that the City was
barred from seeking the payment because it issued the notice of
tax deficiency after the limitations period for an action to
recover taxes had expired. Tesoro also contended that the City
used an unlawful methodology to determine the proportion of
“business conducted within the City” for purposes of calculating
the license tax. (Mun. Code, § 63505.) To file its claim, Tesoro
used the City’s approved form for filing claims under the GCA.
The City denied the claim.
B. The Underlying Action
Tesoro filed this lawsuit, seeking a refund of its additional
payment to the City. The City demurred. It argued that the
action was barred because Tesoro had failed to exhaust the
administrative remedies provided in the Ordinance, including
requesting a refund from the City’s finance director and
appealing any decision to the city manager, before filing a claim
under the GCA. In its opposition, Tesoro argued that it was not
required to exhaust these administrative remedies. It
maintained that the GCA occupies the field of presentation
procedures for damages claims against local public entities, and
that the GCA therefore preempts the Ordinance’s
administrative refund procedures.

4
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

The trial court sustained the City’s demurrer. The court
agreed with Tesoro that its claim for a tax refund was a claim
for money or damages within the meaning of the GCA, but it
disagreed that the GCA preempted the City’s administrative
refund procedures. Citing Richards v. Department of Alcoholic
Beverage Control (2006) 139 Cal.App.4th 304 (Richards), the
court ruled that “[t]he presentation of a claim pursuant to the
GCA is a separate, additional prerequisite to commencing an
action against the state or a local public entity and is not a
substitute for the exhaustion of an administrative remedy.”
Tesoro appealed, and the Court of Appeal affirmed. The
court held that Tesoro failed to meet its burden to show that the
GCA preempted the City’s administrative refund procedures. In
the court’s view, Tesoro did not demonstrate that “the
Legislature sought to fully occupy the field of prescribing the
procedures a taxpayer must follow before suing for refund of
local tax.” (Tesoro Refining & Marketing Co. LLC v. City of
Carson (Feb. 28, 2025, B335686) [nonpub. opn.].) The court
further held that Tesoro forfeited its alternative argument that
several specific provisions of the Ordinance were preempted
because they contradicted the GCA. We granted review to
decide whether a claimant for a local government tax refund
may be required to comply with a local administrative review
procedure before filing a claim under the GCA, or whether the
GCA preempts such a requirement under the doctrine of field
preemption.
II. DISCUSSION
Tesoro contends the Ordinance’s administrative refund
procedures are preempted by the GCA. The City appears to
concede that the GCA “preempts the field of claiming

5
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

requirements” for money and damages claims, but disagrees
that the preempted field extends to the administrative refund
procedures at issue. We conclude that the GCA occupies the
field of presentation requirements for claims for money or
damages against local public entities, and that the Ordinance’s
administrative review procedures — specifically those
established in sections 63515 and 63523 of the Municipal
Code — impose additional requirements for the presentation of
such a claim. Thus, the Ordinance’s additional requirements
are preempted.
A. State and Local Claims Procedures
1. The Government Claims Act
“ ‘From the earliest days of California legal history, a
variety of statutes, municipal charter provisions, and local
ordinances . . . required claims to be presented to public officers
as a condition to maintaining an action against public entities.’ ”
(Minsky v. City of Los Angeles (1974) 11 Cal.3d 113, 120
(Minsky).) Compliance with the applicable “claim statute” was
generally considered “an essential requisite to [a] plaintiff’s
cause of action,” without which the plaintiff was barred from
recovery. (Farrell v. County of Placer (1944) 23 Cal.2d 624, 630;
see Norton v. City of Pomona (1935) 5 Cal.2d 54, 65–66; Farmers
etc. Bank v. City of Los Angeles (1907) 151 Cal. 655, 657–658.)
In 1956, the Legislature adopted a resolution finding that the
existing provisions of law were “extremely varied in their
procedural requirements,” and “so overlapping and inconsistent
that it [was] frequently difficult to ascertain which of the
different provisions controls in a particular case.” (Assem. Conc.
Res. No. 12, Stats. 1956 (1956 Reg. Sess.) res. ch. 35, pp. 256–
257.) In light of these findings, the Legislature directed the

6
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

California Law Revision Commission to make a
recommendation regarding whether such claim presentation
requirements “should be made uniform.” (Id. at p. 257.)
The Law Revision Commission presented its report and
recommendations to the Legislature in 1959. (Recommendation
and Study Relating to The Presentation of Claims Against
Public Entities (Jan. 1959) 2 Cal. Law Revision Com. Rep.
(1959) (1959 Law Revision Commission Report).) According to
the commission, there existed “at least 174 separate claims
provisions” in the state “scattered through statutes, charters,
ordinances and regulations.” (Id. at p. A-7.) The commission
found that these claims provisions were “unduly complex,
inconsistent, ambiguous and difficult to find,” contributed to
unnecessary litigation, and “often result[ed] in the barring of
just claims.” (Ibid.) Accordingly, the commission drafted and
recommended the Legislature enact a general claims statute
that “would govern the presentation of most claims for money or
damages against governmental entities in this State.” (Id. at
p. A-8.) The Legislature enacted the commission’s
recommended claims statute that year. (Stats. 1959, chs. 1724–
1726; see former §§ 700–730.) Four years later, the Legislature
unified the statutes governing claims against local public
entities with those governing claims against the state and its
officers and employees. (Stats. 1963, ch. 1715; see
Recommendation Relating to Sovereign Immunity: Number 2-
Claims, Actions and Judgments Against Public Entities and
Public Employees (Jan. 1963) 4 Cal. Law Revision Com. Rep.
(1963).)
The collective claims statutes are now codified in the GCA.
(See §§ 810–998.3.) As we have explained, the GCA “is a

7
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

comprehensive statutory scheme governing the liabilities and
immunities of public entities and public employees for torts.”
(Quigley v. Garden Valley Fire Protection Dist. (2019) 7 Cal.5th
798, 803.) The presentation requirements for claims are set
forth in part 3 of the GCA. (§§ 900–935.9.) Section 905 states:
“There shall be presented in accordance with [the GCA’s
provisions] all claims for money or damages against local public
entities,” except certain categories of claims specifically
enumerated. Generally, a person may not bring a suit for money
or damages against a government entity until he or she presents
a claim in the manner required by the GCA, and the claim either
“has been acted upon” by the government entity “or has been
deemed to have been rejected.” (§ 945.4; see City of Stockton v.
Superior Court (2007) 42 Cal.4th 730, 738.)
Section 910 sets forth the required contents of the claim.
The claim must include the claimant’s name, address, and the
address for service (§ 910, subds. (a)–(b)); “[t]he date, place and
other circumstances of the occurrence or transaction which gave
rise to the claim” (id., subd. (c)); “[a] general description of the
indebtedness, obligation, injury, damage or loss incurred” (id.,
subd. (d)); the names of the public employees causing the injury,
damage, or loss (id., subd. (e)); and the amount claimed, if less
than $10,000 (id., subd. (f)). The local government entity must
also supply forms for claimants to use that specify the required
information. (§ 910.4.)
Section 915 prescribes how the claimant presents the
claim to the local government entity. The claimant may submit
the claim by one of the following means: “[d]elivering it to the
clerk, secretary, or auditor thereof” (§ 915, subd. (a)(1));
“[m]ailing it to the clerk, secretary, auditor, or to the governing

8
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

body at its principal office” (id., subd. (a)(2)); or transmitting it
electronically in the manner specified, if authorized by an
ordinance or resolution of the public entity (id., subd. (a)(3)).
The claimant is deemed to have complied with section 915’s
requirements if the claim is “actually received by the clerk,
secretary, auditor, or [governing body] of the local public entity.”
(Id., subd. (e)(1); see § 900.2, subd. (a).)
Finally, the GCA imposes strict deadlines on claimants
and local public entities. With few exceptions, the claimant
generally must present the claim within one year of the “accrual
of the cause of action” to which the claim relates. (§ 911.2,
subd. (a).) After the claimant presents the claim, the local
government entity “shall act on a claim . . . within 45 days”
(§ 912.4, subd. (a)) in one of the following ways: rejecting the
claim, allowing the claim in full, allowing the claim in part and
rejecting it in part, or compromising the claim (see § 912.6,
subd. (a)(1)–(4)). The claimant and local government entity may
extend the deadline to act by written agreement. (§ 912.4,
subd. (b).) If the entity does not act on the claim within 45 days
or within the time prescribed by agreement, “the claim shall be
deemed to have been rejected.” (Id., subd. (c).) A person must
file suit within six months after the government entity provides
notice of its decision on the claim or, if no notice is provided,
within two years of the accrual of the cause of action. (§ 945.6,
subd. (a).)
2. The Ordinance
As noted, the Ordinance requires all persons engaged in
the business of operating an oil refinery or facility that stores
petroleum products to pay a quarterly tax based on the gross
receipts of such business conducted within the City. (Mun.

9
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

Code, § 63505.) The taxpayer must “submit a tax return each
calendar quarter” that “include[s] sufficient information,
including gross receipts information, to allow computation of the
tax due.” (Id., § 63507, subd. A.) The taxpayer must also
maintain records from the prior four years as necessary to
determine the tax due. (Id., § 63516.) The City’s finance
director may audit the taxpayer for compliance. If, following an
audit, the finance director determines that the taxpayer has
underpaid the tax, the finance director notifies the taxpayer of
the balance due, and the taxpayer must pay the balance within
30 days. (Ibid.)
The Ordinance includes mandatory procedures for refund
requests. Under the Ordinance, “[n]o refund shall be made
unless a request is received in writing by the Director within one
(1) year of the payment of the tax, interest or penalty to be
refunded.” (Mun. Code, § 63515.) The Ordinance does not set a
deadline by which the finance director must act on a refund
request.
The Ordinance provides that a taxpayer “may appeal any
decision of the Director made under [the Ordinance] to the City
Manager within fifteen (15) days of the decision.” (Mun. Code,
§ 63523, subd. A.) Within 60 days of the filing of the appeal, the
city manager “shall allow an opportunity for submission of
argument and evidence in writing or orally and then determine
whether and to what extent to grant or deny the appeal.” (Id.,
§ 63523, subd. C.) The city manager’s decision on appeal “shall
be final as to the City.” (Ibid.) A taxpayer unsatisfied with the
decision may then seek a writ of administrative mandate under
Code of Civil Procedure section 1094.5. (Mun. Code, § 63523,
subd. C.)

10
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

B. General Principles Governing State Preemption
of Local Laws
Article XI, section 7 of the California Constitution
authorizes a city or county to “make and enforce within its limits
all local, police, sanitary, and other ordinances and regulations
not in conflict with general laws.” However, if an otherwise
valid local law “ ‘ “conflicts with state law, it is preempted by
such law and is void.” ’ ” (Chevron U.S.A., supra, 15 Cal.5th at
p. 142.)
We have “identified three ways in which a preempting
conflict may arise: ‘ “if the local legislation ‘ “[1] duplicates,
[2] contradicts, or [3] enters an area fully occupied by general
law, either expressly or by legislative implication.” ’ ” ’ ”
(Chevron U.S.A., supra, 15 Cal.5th at p. 142.) “Local legislation
is ‘duplicative’ of general law when it is coextensive therewith.”
(Sherwin-Williams Co. v. City of Los Angeles (1993) 4 Cal.4th
893, 897 (Sherwin-Williams).) “[L]ocal legislation is
‘contradictory’ to general law when it is inimical thereto.
[Citation.] [¶] Finally, local legislation enters an area that is
‘fully occupied’ by general law when the Legislature has
expressly manifested its intent to ‘fully occupy’ the area
[citation], or when it has impliedly done so . . . .” (Id. at p. 898.)
We are concerned here with preemption based on a
legislative intent to fully occupy a certain field. “ ‘ “Where the
Legislature has adopted statutes governing a particular subject
matter,” ’ ” we look both to the language of the statutes as well
as the “ ‘ “purpose and scope of the legislative scheme” ’ ” to
determine whether the Legislature intended to occupy the field.
(O’Connell, supra, 41 Cal.4th at p. 1068.) Indicia of the
Legislature’s intent include that “ ‘(1) the subject matter has

11
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

been so fully and completely covered by general law as to clearly
indicate that it has become exclusively a matter of state concern;
(2) the subject matter has been partially covered by general law
couched in such terms as to indicate clearly that a paramount
state concern will not tolerate further or additional local action;
or (3) the subject matter has been partially covered by general
law, and the subject is of such a nature that the adverse effect
of a local ordinance on the transient citizens of the state
outweighs the possible benefit to the’ locality.” (Sherwin-
Williams, supra, 4 Cal.4th at p. 898.)
For example, in American Financial Services Assn. v. City
of Oakland (2005) 34 Cal.4th 1239, 1252 (American Financial
Services), we held that division 1.7 (then-division 1.6) of the
Financial Code (Fin. Code, §§ 4970–4979.8), which regulates
lending practices that typically occur in the subprime mortgage
market, preempted a local ordinance that regulated predatory
lending practices for home mortgages. (American Financial
Services, at pp. 1244–1250.) We explained that division 1.7
evinces “clear indications of the Legislature’s implicit intent to
fully occupy the field of regulation of predatory lending tactics
in home mortgages.” (American Financial Services, at p. 1252.)
The statutes “comprehensively regulate[]” such practices by
“delineat[ing] at length what mortgages are covered, what
lending acts are prohibited, who can be held liable . . . , the
various enforcement mechanisms available, who may invoke
such enforcement mechanisms, and defenses to such violations.”
(Id. at p. 1254.) We also found relevant that the regulation of
mortgage lending “ ‘require[d] uniform treatment throughout
the state,’ ” explaining that home loan securities were sold both
statewide and nationally, and that commercial realities would

12
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

therefore confound local governments’ efforts to impose
inconsistent regulations. (Id. at p. 1256.) Because the local
ordinance at issue attempted to regulate predatory lending
practices for the same mortgages governed by division 1.7 of the
Financial Code, the ordinance encroached upon the field
occupied by state law and was preempted. (American Financial
Services, at pp. 1256–1257.)
In O’Connell, we held that the California Uniform
Controlled Substances Act (UCSA; Health & Saf. Code, § 11000
et seq.), which regulates the possession, use and distribution of
specific controlled substances, preempted a local ordinance that
authorized the forfeiture of any vehicle used to acquire or
attempt to acquire a controlled substance. (O’Connell, supra,
41 Cal.4th at pp. 1069–1071.) We explained that the USCA
“defines controlled substances, regulates their use, and sets
penalties for their unlawful possession and distribution.”
(O’Connell, at p. 1071.) These penalties included vehicle
forfeiture upon proof beyond a reasonable doubt that the vehicle
was used to facilitate specific, enumerated crimes. (Ibid.) “The
comprehensive nature of the UCSA in defining drug crimes and
specifying penalties” was “so thorough and detailed as to
manifest the Legislature’s intent to preclude local regulation.”
(Ibid.) Because the local ordinance authorized vehicle forfeiture
under different circumstances than those prescribed in the
UCSA, the ordinance was preempted.
As our precedents make clear, “[f]ield preemption
generally exists where the Legislature has comprehensively
regulated in an area,” indicating its intent to leave “no room for
additional local action.” (T-Mobile West LLC v. City and County
of San Francisco (2019) 6 Cal.5th 1107, 1122 (T-Mobile West).)

13
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

“The party claiming that general state law preempts a local
ordinance has the burden of demonstrating preemption.” (Big
Creek Lumber Co. v. County of Santa Cruz (2006) 38 Cal.4th
1139, 1149.)
C. The GCA Occupies the Field of Presentation
Requirements for Money or Damages Claims
In considering the preemptive effect of the GCA, we are
not working with a blank canvas. We have previously held that
the GCA preempts a local government entity’s claims
procedures, including those governing claims for a tax refund.
(Volkswagen Pacific, supra, 7 Cal.3d at pp. 62–63, fn. 7.) In
Volkswagen Pacific, the plaintiff brought an action against a city
for the refund of a business license tax, like Tesoro did here. (Id.
at p. 51.) The city’s charter required a taxpayer to present a
claim to the city’s board before suing for a tax refund, and it
allowed the board up to 90 days to act upon receiving the claim.
(Id. at pp. 62, fn. 7, 63.) By contrast, sections 912.4 and 935,
subdivision (d), of the GCA require a local government to act
within 45 days of receiving a claim for money or damages, as
discussed above. (See Volkswagen Pacific, at p. 62, fn. 7.)
Describing the plaintiff’s claim as a “claim for money in the form
of a tax refund,” we held that the GCA’s deadlines applied, and
that the charter provision allowing the board additional time to
act on a tax refund claim was therefore preempted. (Volkswagen
Pacific, at p. 61; see id. at p. 62 & fn. 7.) In so doing, we
explained that “the filing of claims for money or damages
against California government units is an area of statewide
concern in which the Legislature has occupied the entire field.”
(Id. at p. 62, fn. 7, italics added.)

14
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

Our holding in Volkswagen Pacific is consistent with the
text and purposes of the GCA. The requirements for presenting
damages claims to local public entities are “ ‘so fully and
completely covered’ ” by the GCA as to clearly indicate such
requirements are exclusively a matter of state concern; or at
least, the requirements are “ ‘partially covered . . . [and] couched
in such terms’ ” as to clearly indicate that the Legislature “ ‘will
not tolerate further or additional local action.’ ” (Sherwin-
Williams, supra, 4 Cal.4th at p. 898.) The procedures mandated
by the GCA expressly state that they apply to “all claims for
money or damages against local public entities,” unless an
exception applies. (§ 905, italics added.) A “ ‘[l]ocal public
entity’ ” includes any “county, city, district, public authority,
public agency, and any other political subdivision or public
corporation in the State.” (§ 900.4.)
Moreover, the GCA’s prescribed procedures are
themselves comprehensive. They establish the who, what,
when, how, and to whom of filing such claims for damages. The
GCA describes who must present the claim (the claimant or
their representative) (§§ 910, 910.2), when the claimant must
submit the claim (§ 911.2), which form the claimant uses
(§ 910.4), what information the claimant provides (§ 910), which
government official the claimant submits the claim to (§ 915),
how the claimant delivers the claim to the local government
entity (ibid.), and when, after submitting the claim, the
claimant must file a related cause of action (§ 945.6, subd. (a)).
Similarly, the GCA prescribes how and when the local public
entity must rule on a claim for damages. (§ 912.4.)
The interaction between sections 905 and 935 also evinces
the Legislature’s intent to occupy the field of claim presentation

15
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

requirements. Section 905 specifically enumerates several
types of claims against local public entities to which the GCA’s
general presentation requirements do not apply. (§ 905,
subds. (a)–(p).) Section 935, subdivision (a) then states that
those claims excepted by section 905 and “not governed by any
other statutes or regulations expressly relating thereto, shall be
governed by the procedure prescribed in any charter, ordinance,
or regulation adopted by the local public entity.” The statute’s
general application to all types of money and damages claims,
other than a specifically identified subset for which local
governments may enact their own procedures, reflects the
Legislature’s intent to preclude local regulation for those claims
not included in the subset. Like the statutory schemes at issue
in American Financial Services and O’Connell, the GCA’s
provisions are “ ‘extensive in their scope’ ” and “ ‘clearly show an
intention by the Legislature to adopt a general scheme for the
regulation’ ” of the covered subject matter (American Financial
Services, supra, 34 Cal.4th at p. 1254; see id. at pp. 1254–1255).
They are sufficiently comprehensive to demonstrate the
Legislature’s intent to leave “no room for additional local action”
in the field of claims presentation requirements. (T-Mobile
West, supra, 6 Cal.5th at p. 1122.)
When the Legislature enacted the GCA, it also adopted a
complementary constitutional amendment to ensure that the
claims provisions would apply to chartered cities, like the City
of Carson. (Assem. Const. Amend No. 16, Stats. 1959 (1959 Reg.
Sess.) res. ch. 231, p. 5801.) The voters subsequently approved
the amendment. (Cal. Const., art. XI, former § 10, as adopted
Nov. 8, 1960.) As adopted, the amendment provided: “No
provision of this article shall limit the power of the Legislature

16
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

to prescribe procedures governing the presentation,
consideration and enforcement of claims against chartered
counties, chartered cities and counties, and chartered cities, or
against officers, agents and employees thereof.” (Cal. Const.,
art. XI, former § 10, as adopted Nov. 8, 1960.) This amendment
confirms the GCA’s comprehensive scope, including as to charter
cities. Former section 10 of article XI has since been amended
and renumbered as section 12, which now provides: “The
Legislature may prescribe procedure for presentation,
consideration, and enforcement of claims against counties,
cities, their officers, agents, or employees.” However, as we
explained in McWilliams, supra, 56 Cal.4th at page 627, “the
deletion of the reference to chartered cities, chartered counties,
and chartered cities and counties was not intended to change
the scope of the Legislature’s power with respect to chartered
entities.”
Moreover, even if the GCA’s procedures could be viewed as
less than exhaustive, the legislative history confirms that the
Legislature viewed the presentation requirements for damages
claims against local public entities as requiring “ ‘uniform
treatment throughout the state.’ ” (American Financial
Services, supra, 34 Cal.4th at p. 1256.) As discussed, when the
Assembly directed the Law Revision Commission to make a
recommendation on statutory claims procedures, the Assembly
noted that existing procedures adopted by local public entities,
“including cities and districts,” were “extremely varied” as to
“the periods within which various claims shall be filed,” “the
contents of the claim,” and “the person with whom it shall be
filed.” (Assem. Conc. Res. No. 12, Stats. 1956, supra, res. ch. 35,
at pp. 256–257.) The Assembly expressed concern that this

17
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

“lack of uniformity” had caused persons having valid claims to
fail to comply with a technical requirement and lose their rights.
(Id. at p. 257.) Thus, the Assembly concluded that it would “be
in the public interest to have these varying claims statutes,
which have been characterized by the Supreme Court as ‘traps
for the unwary’ (Stewart v. McCollister, 37 Cal.2d 203, 207) . . .
made as uniform as possible.” (Ibid., italics added.)
In its recommendations to the Legislature, the
commission expressed the same concern for the uniform
treatment of presentation requirements for damages claims
against local public entities. The commission noted the
disparities in procedural requirements identified by the
Legislature, as well as others. (1959 Law Revision Com. Rep.,
supra, at p. A-8 [describing differences among “the types of
claims which are subject to presentation requirements, the time
limits for presenting claims, the official to whom claims must be
presented, the information which the claimant must furnish, the
requirements of verification and signature, the time allowed for
consideration of the claim by the governmental entity and the
time allowed for commencing an action after a claim is
rejected”].) Thus, the commission proposed to the Legislature a
“single statutory enactment” setting forth a procedure
“applicable to claims [for money or damages] against all forms
of governmental agencies below the State level.” (Id. at p. A-
116.) The Legislature’s decision to adopt the commission’s
recommendations confirms that it shared the view when it
ultimately enacted the GCA. (See Estate of Joseph (1998)
17 Cal.4th 203, 216 [“we give ‘substantial weight’ to the
commission’s understanding of a provision it proposed”]; In re
Marriage of Buol (1985) 39 Cal.3d 751, 761 [commission’s report

18
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

“elucidate[s] the reasoning” of the Legislature in enacting the
statute].) Indeed, the Office of Legislative Counsel’s report on
Assembly Bill No. 405 (1959 Reg. Sess.) — the bill that
introduced the GCA’s claims provisions — specifically referred
to the commission’s 1959 report and explained that the bill was
one of several recommended by the commission “relating to
claims against public entities and having as a principal purpose
the creation of a greater degree of uniformity in the law in this
field.” (Legis. Counsel, Rep. on Assem. Bill No. 405 (1959 Reg.
Sess.) p. 2.) The express statements from both the Legislature
and the commission, coupled with the extensive procedures
enacted by the Legislature, reveal that the Legislature viewed
the requirements for presenting money and damages claims
against local government entities as a matter of statewide
concern, for which it would tolerate no additional local
requirements.
D. The GCA Preempts the Ordinance’s Refund
Procedures
The City does not directly dispute whether the GCA
occupies the field of presentation requirements for claims
against local public entities. Its primary argument is that the
Ordinance’s administrative refund procedures do not involve a
claim for purposes of the GCA and therefore fall outside the
GCA’s preemptive scope. To determine whether the GCA
impliedly preempts the administrative refund procedures at
issue here, we first determine the precise field the Legislature
intended to occupy. (Candid Enterprises, Inc. v. Grossmont
Union High School Dist. (1985) 39 Cal.3d 878, 886, fn. 4; In re
Hubbard (1964) 62 Cal.2d 119, 125; People v. Nguyen (2014)
222 Cal.App.4th 1168, 1177–1178.) We then consider the

19
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

subject matter of the local ordinance. If the local ordinance
imposes additional requirements, or supplements,
complements, or otherwise seeks to regulate within the field
occupied, it is preempted. (O’Connell, supra, 41 Cal.4th at
p. 1068; American Financial Services, supra, 34 Cal.4th at
p. 1252; Lancaster v. Municipal Court (1972) 6 Cal.3d 805, 807–
808.)
As discussed, the text and legislative history
accompanying the GCA reveal that the field preempted is the
presentation requirements for claims for money or damage
against local public entities. (See § 905 [“There shall be
presented” in accordance with the GCA’s provisions “all claims
for money or damages against local public entities,” unless
specifically excepted (italics added)]; Code Civ. Proc., § 313 [“the
presentation of claims as a prerequisite to commencement of
actions for money or damages against the State of California,
counties, cities, cities and counties, districts, local authorities,
and other political subdivisions of the State, and against the
officers, employees, and servants thereof, is prescribed” by the
GCA (italics added)].) The question is therefore whether the
City’s administrative review procedures seek to impose
additional requirements for the presentation of a claim for
money or damages, or otherwise regulate the subject area.
The GCA does not define a “claim.” However, the meaning
of a claim can be gleaned from its use within the statutory
scheme. When the Legislature enacted the GCA, a claim was
generally understood as the “ ‘assertion of an existing right.’ ”
(Supera v. Moreland Sales Corp. (1938) 28 Cal.App.2d 517, 521,
italics omitted; see Mellus v. Potter (1928) 91 Cal.App. 700, 704.)
The text of the GCA confirms this understanding. The GCA

20
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

requires the claimant to include certain information describing
the nature of the claim, including the date, place, and
circumstances of the occurrence or transaction which give rise
to the claim, and a “general description of the indebtedness,
obligation, injury, damage or loss incurred.” (§ 910, subd. (d).)
The GCA also makes clear that a claim is inextricably tied to a
related cause of action. The claim must be presented to the local
government entity within either six months or one year of the
“accrual of the cause of action.” (§ 911.2, subd. (a).) This date of
accrual, in turn, is defined as the date the cause of action would
accrue for purposes of an otherwise applicable statute of
limitations “if there were no requirement that a claim be
presented to and be acted upon by the public entity before an
action could be commenced.” (§ 901.) Thus, a claim under the
GCA encompasses the assertion of an underlying substantive
right, which is independent from — and unaffected by —
whatever presentation requirements the public entity seeks to
impose.
The 1959 Law Revision Commission Report confirms this
broad understanding of a claim. In the opening paragraph of its
recommendation, the commission explained: “The law of this
State contains many statutes and county and city charters and
ordinances which bar suit against a governmental entity for
money or damages unless a written statement or ‘claim’ setting
forth the nature of the right asserted against the entity, the
circumstances giving rise thereto and the amount involved is
communicated to the entity within a relatively short time after
the claimant’s cause of action has accrued. Such provisions are
referred to in this Recommendation and Study as ‘claims
statutes.’ ” (1959 Law Revision Com. Rep., supra, at p. A-7.)

21
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

Similarly, in its survey of the 174 claims statutes across
the state, the commission noted that some local government
entities had used the term “demand[]” rather than “claim” to
describe the prelawsuit presentation requirement. (1959 Law
Revision Com. Rep., supra, at pp. A-24 to A-28, A-57 to A-60.)
In discussing one city charter that used both terms, the
commission explained: “If the framers of these provisions were
observing a distinction between ‘demands’ and ‘claims,’ it is not
apparent what the difference is.” (Id. at p. A-60.)
The claims subject to the GCA are those for “money or
damages.” (§ 905.) Damages have long been defined in this
state as compensation “in money” for detriment caused by the
unlawful act or omission of another. (Civ. Code, § 3281; see AIU
Ins. Co. v. Superior Court (1990) 51 Cal.3d 807, 825 [explaining
that Civ. Code, § 3281 is intended to capture “the plain and
ordinary meaning of the word”]; Wainscott v. Occidental etc.
Assn. (1893) 98 Cal. 253, 255 [term “ ‘damages’ signifies a
compensation in money for a loss or damage”]; Black’s Law Dict.
(4th ed. 1951) p. 466, col. 2 [defining “damages” as “[a] pecuniary
compensation or indemnity”].) The text of the GCA confirms
this understanding. The claimant must state in its claim either
the amount demanded or whether the claim would be a limited
civil case. (Gov. Code, § 910, subd. (f).) The local government
entity then acts by either “allow[ing]” or “reject[ing]” all or part
of the claim, i.e., paying or rejecting the demand. (Id., § 912.6,
subd. (a).)
Both the GCA’s text and extrinsic evidence of the
Legislature’s intent therefore show that the phrase “claims for
money or damages,” as used in the GCA (§ 905), encompasses
any prelawsuit demand asserting a right to monetary

22
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

compensation for an alleged unlawful act or omission. The
refund request required by the Ordinance plainly falls within
this definition. After paying the tax, the taxpayer must submit
the written refund request to the City’s finance director, and the
taxpayer must do so within one year of paying the tax to be
refunded. (Mun. Code, § 63515.) Such a request for a tax refund
is a demand asserting a right to monetary compensation for an
unlawful act or omission, i.e., a type of claim for money or
damages. Indeed, at the time the Legislature enacted the GCA,
it was well understood that a taxpayer could assert a cause of
action to recover an allegedly unlawful tax paid under protest.
(See Northrop Aircraft v. Cal. Emp. Com. (1948) 32 Cal.2d 872,
881–882; Flynn v. San Francisco (1941) 18 Cal.2d 210, 216;
Vitale v. City of Los Angeles (1936) 13 Cal.App.2d 704, 707.)
The City’s contention that its refund procedures do not
encompass a claim for purposes of the GCA is also inconsistent
with our decisions in Volkswagen Pacific, supra, 7 Cal.3d 48 and
McWilliams, supra, 56 Cal.4th 613. As discussed, in
Volkswagen Pacific, the plaintiff sued a city to recover the
payment of a business license tax. (Id. at p. 51.) Because we
determined that the plaintiff’s claim was a “claim for money in
the form of a tax refund” (id. at p. 61), we held the GCA’s
deadline for a local government entity to act on a claim applied,
rather than the deadline established by the city’s charter. (See
Volkswagen Pacific, at p. 62, fn. 7.) Under the City’s reasoning
in this case, the city in Volkswagen Pacific could have first
required the taxpayer — before filing a claim under the GCA —
to file a refund claim pursuant to the procedures established in
its charter (including the extended time for the city to make a

23
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

decision). Our contrary holding in Volkswagen Pacific forecloses
the City’s position. (Volkswagen Pacific, at p. 62 & fn. 7.)
In McWilliams, we similarly held that claims for tax
refunds against local government entities are governed by the
GCA and are therefore necessarily claims for money or damages.
There, the plaintiff sought a refund of the city’s telephone users
tax on behalf of himself and other residents. The city had
enacted a local ordinance governing tax refunds, which barred
class claims. (McWilliams, supra, 56 Cal.4th at pp. 619–620 &
fns. 3, 4.) The city contended the tax refund claim was excepted
from the GCA’s requirements under section 905, subdivision (a),
which covers clams “under the Revenue and Taxation Code or
other statute prescribing procedures for the refund, rebate,
exemption, cancellation, amendment, modification, or
adjustment of any tax, assessment, [or] fee.” (See McWilliams,
at pp. 619–620.) We held in McWilliams that a local ordinance
does not constitute a “[s]tatute” for purposes of the exception.
(See id. at pp. 619–629; § 811.8 [defining a “ ‘[s]tatute,’ ” for
purposes of the GCA, as “an act adopted by the Legislature of
this State or by the Congress of the United States, or a statewide
initiative act”].) The GCA’s procedures therefore applied, and
the local ordinance’s bar on class claims could not be enforced.
(McWilliams, at pp. 628–629.) While the City seeks to minimize
the relevance of McWilliams, our holding necessarily implied
that a request for a local tax refund is a claim for money or
damages for purposes of the GCA, and a local government’s own
procedural requirements for how persons bring such claims are
preempted. Like Volkswagen Pacific, McWilliams cannot be
squared with the City’s position that its refund procedures do
not involve a claim.

24
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

Having concluded (1) that the GCA preempts the field of
presentation requirements for money or damages claims, and
(2) that the City’s required refund requests constitute claims for
money or damages, the only remaining question for purposes of
the field preemption analysis is whether the City’s
administrative refund procedures impose additional
requirements or otherwise fall within the field occupied by the
GCA. The answer is yes. The GCA establishes a
straightforward presentation process: the taxpayer presents a
claim for money or damages, i.e., a request for a tax refund, with
the “clerk, secretary, or auditor” of the local government entity,
which is deemed presented if actually received by the
government entity’s board or any of the aforementioned
individuals. (§ 915, subd. (a).) The government entity then has
45 days to rule on the claim before it is deemed denied and the
taxpayer may bring a lawsuit against the entity on the cause of
action alleged in the claim. (§ 911.6.) By contrast, the
Ordinance requires a taxpayer who wishes to present a refund
request to (1) file the request with the City’s finance director
(Mun. Code, § 63515); (2) if unsuccessful, file a written appeal of
any adverse decision to the city manager that includes a
description of the “matter being appealed” (id., § 63523,
subd. A.2.) and a “statement of the grounds of appeal” (id.,
§ 63523, subd. A.3.); and (3) if unsuccessful again, file a petition
for writ of administrative mandate in a superior court (id.,
§ 63523, subd. C., see Code Civ. Proc., § 1094.5) — all in
addition to the GCA’s own procedures. This multistep process
plainly imposes requirements that exceed those of the GCA.
Moreover, the Ordinance provides no deadline for the
finance director to issue the initial decision, and the city

25
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

manager has up to 60 days to rule on the appeal. Thus, the
Ordinance allows for a longer period between the claimant’s
filing of the claim and date the claimant may bring a legal
action. Because the Ordinance seeks to impose additional
requirements and regulations in the field occupied by the GCA,
it is preempted.
The City argues that exhaustion of its refund procedures
and appeal is a “prerequisite” to a claim under the GCA, rather
than a claim itself. This argument is unpersuasive. As
discussed, a claim for money or damages, for purposes of the
GCA, is an assertion of a legal right to monetary compensation.
The taxpayer presents the claim to the public entity once a cause
of action accrues in the conventional fashion — that is, once it
accrues without regard to whatever procedural presentation
requirements the local government entity seeks to impose. After
a taxpayer pays a disputed tax, its legal right to recovery accrues
in the usual fashion. The assertion of that right to the City,
whether through an administrative refund procedure and
subsequent appeal, or otherwise, is a claim. (See McWilliams,
supra, 56 Cal.4th at pp. 628–629.)
The City and amici curiae California State Association of
Counties and League of California Cities attempt to recast the
Ordinance’s refund procedure as providing an administrative
remedy, rather than allowing for a claim, to avoid the
preemptive effect of the GCA. According to amici curiae, the
requirement to exhaust administrative remedies is a “judicially
developed” doctrine of procedure that “operates as a structural
component of the judicial process,” independent of “whichever
legislative body enacted the administrative procedures in
question.” Thus, amici curiae contend, the requirement to

26
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

exhaust administrative remedies “is entirely outside the ‘field’
addressed by the GCA.”
This argument misunderstands the nature of the
administrative exhaustion doctrine. The doctrine generally
requires a party to seek relief though available administrative
review procedures before resorting to courts. (California
Correctional Peace Officers Assn. v. State Personnel Bd. (1995)
10 Cal.4th 1133, 1151.) It is “grounded on policy concerns
related to administrative autonomy and judicial efficiency.”
(Plantier v. Ramona Municipal Water Dist. (2019) 7 Cal.5th 372,
383.) However, the doctrine says nothing about the validity of
a local government’s administrative review procedures, or
whether those procedures might be preempted by conflicting
state law. Here, the Ordinance requires a taxpayer to file a
refund request — a type of claim for money or damages —
pursuant to the procedures established in sections 63515 and
63523 of the Municipal Code. It is these distinct procedural
requirements that the GCA preempts. Because they are
preempted, the exhaustion doctrine cannot operate to require a
taxpayer to adhere to such procedural requirements before
seeking relief in the courts.
Moreover, we have recognized that a party is not
necessarily required to exhaust an administrative remedy
where a separate prelawsuit procedure fulfills identical
purposes. (See City of Los Angeles v. Superior Court (1973)
8 Cal.3d 723, 729–732 [police officer discharged following an
administrative hearing was not required to file request for
reinstatement with separate administrative body]; Friends of
Mammoth v. Board of Supervisors (1972) 8 Cal. 3d 247, 267–268
[named representative in class action was not required to

27
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

exhaust administrative remedy where unnamed class members
had unsuccessfully sought administrative relief].) The GCA’s
requirement that a person first present a claim for consideration
before bringing suit, and the Ordinance’s requirement that a
taxpayer first file a refund request, serve largely the same
purposes, and in a similar fashion. The “core purposes” of the
GCA’s presentation requirements are to “ ‘give the
governmental entity an opportunity to settle just claims before
suit is brought[, and to] permit the entity to make an early
investigation of the facts on which a claim is based, thus
enabling it to defend itself against unjust claims and to correct
the conditions or practices which gave rise to the claim.’ ” (Arntz
Builders v. City of Berkeley (2008) 166 Cal.App.4th 276, 289.)
The refund procedures established in the Ordinance offer the
City the same opportunity to make an investigation, correct its
practices, and settle a taxpayer’s claims before the taxpayer may
bring the City to court. The City fails to offer any legitimate
rationale for its position that a taxpayer should be required to
both exhaust the three-step refund procedure established in the
Ordinance — filing a request, appeal, and writ petition — before
then filing an additional claim in accordance with the provisions
of the GCA. Affording the City two opportunities to conduct the
same investigation and make the same determination before the
taxpayer may file suit in court “would serve no additional useful
purpose.” (Friends of Mammoth, at p. 268.)
In short, the City’s characterization of the Ordinance’s
refund procedures as an administrative remedy or
“prerequisite” to a claim does not affect what they are for
purposes of our field preemption analysis. The relevant inquiry
is not how the City characterizes its procedures, but what field

28
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

of regulations the Legislature intended to occupy, and whether
the procedures fall within that field. Because the City’s required
refund request is a “claim[] for money or damages” within the
meaning of the GCA (§ 905), and because the City seeks to
impose its own requirements for presenting such claims, the
City’s refund procedures are preempted and a taxpayer is not
required to comply with such procedures before bringing a
lawsuit. Indeed, if local public entities were allowed to impose
additional procedural requirements on claimants in the form of
claim “prerequisites,” or if the exhaustion doctrine required a
claimant to comply with any claims process the local
government entity sought to impose, it would resurrect exactly
the patchwork of unique local procedural requirements the GCA
was intended to displace.
Sipple v. City of Hayward (2014) 225 Cal.App.4th 349
supports this analysis. In Sipple, an Internet service provider
filed claims with several cities and counties, on behalf of its
subscribers, for refunds of access taxes which the service
provider had charged and collected from its customers and
remitted to the cities and counties. (Id. at pp. 353–354.) The
cities and counties argued that the service provider failed to
comply with the tax refund procedures established in the cities’
and counties’ local ordinances, which required the providers to
first refund the disputed taxes to customers before filing refund
claims. (Id. at p. 357.) The Court of Appeal held that the
provider was not required to comply with these local ordinances.
(Id. at pp. 357–358.) It reasoned that, “[t]o the extent that the[]
‘refund first’ ordinances establish a precondition to filing a
claim, they are preempted by the Government Claims Act.” (Id.
at p. 357.) Just as the cities and counties in Sipple could not

29
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

require the service provider to refund customers as a
“precondition” to bringing a claim for a tax refund under the
GCA (Sipple, at p. 357), the City may not require a taxpayer to
exhaust its additional refund procedures as a “prerequisite” to
bringing a claim.
The City and amici curiae also argue that a local public
entity’s adoption of administrative claims requirements can be
beneficial, as shown by the purposes underlying the exhaustion
doctrine. Requiring parties to first exhaust available
administrative remedies eases the burden on courts by allowing
an administrative agency to sift the relevant evidence, facilitate
the development of a complete record that draws on the agency’s
expertise, and provide a remedy at the administrative level if
appropriate. (See Center for Biological Diversity v. Department
of Fish & Wildlife (2015) 62 Cal.4th 204, 239; Tomlinson v.
County of Alameda (2012) 54 Cal.4th 281, 291.) But whatever
the merits of additional local administrative procedures, the
Legislature by enacting the GCA plainly intended to preempt
them for several types of money and damage claims, including
the one at issue here.
Indeed, sections 905 and 935 reflect the Legislature’s view
that local governments should be permitted to enact unique,
prelawsuit administrative review procedures for certain types of
damages claims, but not for the tax refund claims at issue here.
As discussed, section 935, subdivision (a) states that, for those
claims excepted by section 905, “the procedure prescribed in any
charter, ordinance, or regulation adopted by the local public
entity” shall govern where no other state statute or regulation
governs the claim. In its recommendation to the Legislature,
the Law Revision Commission explained that the objectives

30
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

supporting a uniform presentation procedure did not apply to
the claims excepted by section 905; instead, the “claims
procedure should be closely and directly integrated into [the]
substantive policies” of the claim. (1959 Law Revision Com.
Rep., supra, at p. A-117.) As we have recognized, the
Legislature specifically declined to except claims for local tax
refunds not governed by a state statute. (See McWilliams,
supra, 56 Cal.4th at p. 623 [“the legislative history does not
support the City’s contention that the Legislature intended to
preserve plenary control by local governments over the
procedures for local tax refunds”].) To the extent the Legislature
determines local governments should have greater discretion
over the review procedures governing certain types of claims,
the Legislature has the authority to create additional exceptions
under section 905. But we cannot substitute our judgment for
that of the Legislature in this regard.3
The City relies on several lower court opinions that it
contends reflect the broad principle that the GCA does not
preempt local administrative remedies. (See Cornejo v.
Lightbourne (2013) 220 Cal.App.4th 932; Richards, supra,
139 Cal.App.4th 304; Parthemore v. Col (2013) 221 Cal.App.4th
1372; Lozada v. City and County of San Francisco (2006)
145 Cal.App.4th 1139; Bozaich v. State of California (1973)

3
Our decision does not impact refund procedures for
property taxes, sales and use taxes, and other “local” taxes that
are prescribed by the Revenue and Taxation Code or other state
statute. (Gov. Code, § 905.) Nor does our decision impact the
general requirement that a party exhaust available,
nonduplicative administrative remedies for claims other than
“claims for money or damages against local public entities.”
(Ibid.)

31
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

32 Cal.App.3d 688.) Each of these cases is distinguishable.
None addressed a local ordinance that imposed mandatory
administrative procedures for requesting a tax refund or
otherwise presenting a claim for money or damages. Richards
considered whether compliance with the GCA excuses the
requirement to exhaust an administrative remedy established
by the Legislature as part of a statewide statutory scheme
(Richards, at pp. 313–316), while Cornejo conversely considered
whether compliance with a similar state administrative review
process excused compliance with the GCA (Cornejo, at pp. 938–
942). Lozada, Parthemore, and Bozaich each involved a plaintiff
who failed to comply with the GCA altogether, and each
considered whether the GCA and the administrative procedures
at issue were sufficiently analogous such that a party’s excusal
from compliance with one necessarily excused compliance with
the other. (Parthemore, at pp. 1381–1384; Lozada, at pp. 1153–
1159; Bozaich, at pp. 697–699.) None of these cases addressed
the dispositive question here: whether a local public entity may
impose additional procedural requirements on a plaintiff
seeking to present a claim for money or damages.
The City and amici curiae also cite several cases in which
a plaintiff was required to exhaust local administrative
remedies before filing a lawsuit, including local administrative
procedures for challenging a tax. (See Los Globos Corp. v. City
of Los Angeles (2017) 17 Cal.App.5th 627; Flying Dutchman
Park, Inc. v. City and County of San Francisco (2001)
93 Cal.App.4th 1129; Park ’N Fly of San Francisco, Inc. v. City
of South San Francisco (1987) 188 Cal.App.3d 1201.) However,
none of these cases considered the effect of the GCA on the
administrative review procedures at issue. While the plaintiffs

CARSON
Opinion of the Court by Guerrero, C. J.

in Park ’N Fly and Flying Dutchman brought challenges to local
tax assessments, neither sought the recovery of taxes paid or
otherwise asserted a cause of action seeking recovery of money
or damages. Thus, the GCA did not apply. (See Park ’N Fly, at
pp. 1206–1207; Flying Dutchman, at pp. 1132–1133.) Los
Globos involved local review procedures enabling the plaintiff to
challenge only the city’s permit determinations. (Los Globos, at
pp. 633–634.) Unlike the Ordinance here, the applicable local
laws did not require the plaintiff to follow distinct procedures
for filing claims for money or damages. (Ibid.) Los Globos also
did not meaningfully address the GCA. It only mentioned in
passing that the defendant argued in the trial court that the
plaintiff failed to comply with the statute in addition to failing
to exhaust administrative remedies. (Los Globos, at p. 631.)
None of these cases supports the City’s and amici curiae’s
contention that the GCA does not preempt local administrative
remedies involving money or damages claims.
Finally, the City invokes the home rule provision of
article XI, section 5 of the California Constitution to support its
contention that the GCA does not preempt the tax refund
procedures established in the Ordinance. The home rule
provision generally affirms a charter city’s power to regulate its
municipal affairs, including the power to raise revenue via
taxation. (City and County of San Francisco v. Regents of
University of California (2019) 7 Cal.5th 536, 544–545.)
However, as discussed, the Legislature adopted and the voters
approved a constitutional amendment to confirm that claims
presentation procedures enacted by the Legislature —
specifically those in the GCA — would apply to chartered cities.
(1959 Law Revision Com. Rep., supra, at p. A-9; see Cal. Const.,

33
TESORO REFINING & MARKETING COMPANY LLC v. CITY OF
CARSON
Opinion of the Court by Guerrero, C. J.

art. XI, former § 10, as adopted Nov. 8, 1960, now art. XI, § 12.)
As we explained in McWilliams, article XI, section 12 makes
clear that “the home rule protections in the Constitution do not
limit the Legislature’s authority to prescribe procedures
governing claims against chartered local government entities.”
(McWilliams, supra, 56 Cal.4th at p. 627.)
Ultimately, the City’s position that it can enact its own tax
refund procedures is fundamentally at odds with the
Legislature’s stated purpose in enacting the GCA’s claims
presentation requirements. The Legislature sought to remedy
the fact that persons with valid claims had “unjustly” lost their
rights by failing to comply with the distinct requirements
imposed by local government entities in their claims statutes.
(Assem. Conc. Res. No. 12, Stats. 1956, supra, res. ch. 35, at
p. 257; see Minsky, supra, 11 Cal.3d at p. 120 [“As noted by
many commentators, these diverse claims presentation
requirements often created unnecessary ‘traps for the
unwary’ ”]; Viles v. State of California (1967) 66 Cal.2d 24, 31
[“ ‘Both the courts and Legislature have recognized that the
labyrinth of claims statutes previously scattered throughout our
statutes were traps for the unwary. [Citations.] An attempt has
been made by the Legislature to remove such snares’ ”].)
Requiring a person with a valid tax refund claim to both file a
claim under the GCA, and comply with a separate
administrative refund procedure, creates precisely the type of
procedural trap the GCA was intended to eliminate. Permitting
a government entity to enforce such a requirement would
frustrate the Legislature’s intended goal in enacting a “uniform”

procedure for the presentation of claims for money or damages.
(Assem. Conc. Res. No. 12, at p. 257.)4
III. DISPOSITION
The GCA preempts the field of presentation requirements
for claims for money or damages against local public entities,
including claims for a local tax refund. Because sections 63515
and 63523 of the Municipal Code impose additional
requirements on a taxpayer seeking to present a postpayment
claim for a local tax refund, they are preempted. A taxpayer is
not required to comply with such requirements before filing a
claim under the GCA or seeking relief in court. The judgment
of the Court of Appeal is reversed, with directions to reverse the

The City raises the possibility that Tesoro could have filed
an appeal of the notice of deficiency directly with the city
manager under section 63523 of the Municipal Code before
paying the contested tax and seeking a refund. To the extent
the City is arguing that a prepayment appeal of the notice of
deficiency was an additional administrative remedy that Tesoro
was required to exhaust, we decline to consider this argument.
In its briefing in the trial court, Tesoro argued that the text and
structure of the Ordinance did not require it to file an appeal
with the city manager until the finance director first made a
determination on a refund request. In reply, the City confirmed
this understanding of the Ordinance’s requirements and
disclaimed any argument to the contrary. Neither the trial
court nor the Court of Appeal considered the possibility that
Tesoro could or should have sought administrative review of the
notice of deficiency before paying the contested tax, and we
decline to do so for the first time here. Our preemption holding
is limited to local, mandatory procedures governing how
taxpayers may seek a postpayment tax refund, like those set
forth in Municipal Code sections 63515 and 63523 (at least
insofar as Mun. Code, § 63523 governs appeals from the City’s
refund decisions).
