THE SUPERIOR COURT OF OPINION
RIVERSIDE COUNTY,
Respondent;
RIVERSIDE COUNTY DEPARTMENT
OF PUBLIC SOCIAL SERVICES,
Real Party in Interest.
ORIGINAL PROCEEDINGS; petition for writ of mandate. Mark E. Petersen,
Judge. Petition granted.
Ruben Mejia, in pro. per., for Petitioner.
No appearance for Respondent.
Minh C. Tran, County Counsel, and Julie Jarvi, Deputy County Counsel, for Real
Party in Interest.
1
Petitioner filed a petition for writ of mandate to reverse the trial court’s denial of
his motion for disqualification pursuant to Code of Civil Procedure section 170.6,
subdivision (a)(2). (Unlabeled statutory citations refer to this code.) This court invited
respondent and real party in interest to respond, and we advised the parties that we were
considering issuing a peremptory writ in the first instance pursuant to Palma v. U.S.
Industrial Fasteners, Inc. (1984) 36 Cal.3d 171, 178. On May 21, 2026, real party in
interest filed a response indicating they did not oppose the petition1. Having received no
opposition and good cause being shown, we grant the petition and issue a peremptory
writ in the first instance directing the respondent court to vacate its order denying
petitioner’s motion, and to enter a new order granting the motion.
BACKGROUND
Petitioner is a self-represented father in juvenile dependency proceedings. On
October 27, 2025, petitioner filed Welfare and Institutions Code section 388 petitions as
to his two children. On October 29, 2025, Judge Kubelun summarily denied the
petitions. On April 6, 2026, this court issued an opinion reversing and remanding to the
juvenile court with directions to conduct a new hearing to consider the merits of the
petitions under Welfare and Institutions Code section 388, including any evidence
developed after the filing of his petition.
1 This court also received an unsolicited filing from petitioner, on May 28, 2026, which
contains a request for judicial notice. The request for judicial notice is denied. (Evid.
Code, §§ 451, 452.)
2
Upon remand, on April 14, 2026, Mejia filed a declaration seeking to disqualify
Judge Kubelun pursuant to section 170.6. Judge Petersen denied petitioner’s challenge
the same day as untimely.
STANDARD OF REVIEW
Where the underlying material facts are not in dispute, we review a trial court’s
denial of a section 170.6 challenge de novo. (Garcia v. Superior Court (2023)
92 Cal.App.5th 47, 54.)
DISCUSSION
Section 170.6 allows a party to file a disqualification motion “following reversal
on appeal of a trial court’s decision, or following reversal on appeal of a trial court’s final
judgment, if the trial judge in the prior proceeding is assigned to conduct a new trial on
the matter.” (§ 170.6, subd. (a)(2).) The term “new trial” is not limited to jury trials or
court trials but is intended to cover situations in which the case is to be retried and not
merely remanded with instructions to perform a specific task. (State Farm Mutual
Automobile Ins. Co. v. Superior Court (2004) 121 Cal.App.4th 490, 496 (State Farm).)
Application of subdivision (a)(2) of section 170.6 “does not turn on … whether the
issue(s) to be resolved on remand are limited, but what the court must do to resolve them.
If the court’s function is merely a ministerial act (such as the recalculation of interest),
[this rule] does not apply.” (State Farm, supra, at p. 496.) The statute requires that the
motion be made within 60 days after receiving notice of the assignment. (Ibid.)
3
This court’s opinion in the prior appeal reversed Judge Kubelun’s ruling denying
petitioner’s Welfare and Institution Code section 388 petitions. The petition and record
reflect that on remand the case was again assigned to Judge Kubelun for compliance with
this court’s directions. Petitioner filed his challenge within 60 days of receiving notice of
the assignment, as required. Although this matter does not involve a court trial or a jury
trial, we have directed the juvenile court to consider petitioner’s Welfare and Institution
Code section 388 petitions on the merits, and that is not a merely ministerial act. For all
of these reasons, the court erred by denying petitioner’s motion for disqualification as
untimely. We therefore grant the writ petition and direct the trial court to grant the
motion.
DISPOSITION
Let a peremptory writ of mandate issue directing the respondent superior court to
vacate its order denying petitioner’s motion for disqualification of Judge Kubelun
pursuant to section 170.6, subdivision (a)(2), and to enter a new order granting
disqualification and assigning the case to a different judge. The temporary stay is
dissolved upon issuance of the remittitur.
