When is a California civil Court of Appeal decision final?

Decision filing and each legally relevant finality-changing event

A thirty-day period is the ordinary branch. A judicial holiday does not automatically postpone finality for the petition-for-review calculation under rule 8.500(e)(1).

Responsible actor. The court determines finality; a party must establish it before using a finality-triggered procedure. Identify the kind of civil decision, all publication and modification orders, any conditional affirmance consent and any actual rehearing grant or emergency order.

Civil decision finality follows the specific branches of rule 8.264. Rule 8.500(e)(1) does not postpone finality for a closed clerk office. Party filing deadlines have their separate final-holiday treatment. CCP 12 excludes the triggering day for ordinary day periods. CCP 12a supplies the final judicial-holiday adjustment, including Saturdays and the CCP 135 holidays. CCP 12b addresses qualifying whole-day office closures. Court-day periods exclude intermediate Saturdays, Sundays and judicial holidays. Calendar-day periods include intermediate closed days. Rule 1.11 supplies Friday observance of a Saturday judicial holiday and Monday observance of a Sunday judicial holiday. The calendar includes Lincoln Day, March 31, Juneteenth, Native American Day and Thanksgiving Friday. It excludes Columbus Day and Good Friday as ordinary full judicial holidays. The observed New Year holiday on December 31, 2027 is confirmed in the county schedule. Actual additional closures require separate evidence.

Establish the actual service method and legally completed event. The tax-cost preset is confined to personal service; rule 3.1700(b)(1) expressly recognizes CCP 1013 mail and CCP 1010.6 electronic additions. Filing-triggered brief and review-answer clocks do not begin merely with service. CCP 1013 and 1010.6 exclude their stated additions for a notice of appeal. A summons-service event and an appellate filing event have distinct requirements. These presets do not calculate excluded service or combined procedural branches.

Official 2026 Rules of Court were reviewed. Publication coverage begins January 1, 2026 and assumes the reviewed branch still governs the input. Displayed final dates use the independently retained 2026 and 2027 California judicial calendar. Earlier or amended editions, emergency orders and actual additional closures require separate review. A closed backward statement boundary receives no date because its exact adjustment is not implemented. Source guides for combined appeal clocks, stipulated responses, cost memoranda and decision finality supply no computed or paid date. These software coverage boundaries do not establish that an actual filing is late.

Two modifications filed on the same date can have different finality effects because only one changes the appellate judgment. A closed ordinary finality day does not become the next open day for review timing. No single opinion-filing input resolves these branches.

Ordinary thirty-day finality, immediate-finality decisions and publication, judgment-changing modification, consent or rehearing branches

Final on filing

Supersedeas denials and dismissals on request or stipulation are final on filing under rule 8.264(b)(2).

Publication and judgment-changing modification

A qualifying publication order restarts finality. A modification changing the appellate judgment restarts it; a modification not changing judgment does not.

Conditional affirmance consent

Filing the consent described in rule 8.264(d) starts the identified thirty-day finality period.

Rehearing petition versus grant

A mere rehearing petition does not automatically postpone finality. If not ruled on before finality, it is deemed denied; a rehearing grant vacates the decision.

Closed clerk office

The court's next-open-day authority to modify under rule 8.264(c)(1) does not establish a general postponement of finality. Rule 8.500(e)(1) expressly denies that postponement for review timing.

Actual emergency order

Rule 8.66 permits specified emergency tolling or extensions and renewals. Check the order's scope and dates; the rule does not add time merely because an emergency occurred.

Service methods and distinct statutory additions

Establish the actual service method and legally completed event. The tax-cost preset is confined to personal service; rule 3.1700(b)(1) expressly recognizes CCP 1013 mail and CCP 1010.6 electronic additions. Filing-triggered brief and review-answer clocks do not begin merely with service. CCP 1013 and 1010.6 exclude their stated additions for a notice of appeal. A summons-service event and an appellate filing event have distinct requirements. These presets do not calculate excluded service or combined procedural branches.

• Finality is a court status, not a party filing deadline. For rule 8.500, finality is not extended because the clerk office is closed. Preserve the actual decision and every relevant order. Under rule 8.25, filing ordinarily uses actual clerk receipt. Specified briefs and review documents have a timely priority or express mail or overnight carrier dispatch exception; the exception does not change the actual filing date used by a later filing-triggered period. Ordinary mail does not receive that exception. Custodial mailing has a separately stated exception. Rule 8.77 supplies electronic receipt and filing confirmations, next-court-day treatment after 11:59 p.m. and good-cause relief for failed transmission. Preserve receipt, filing and service proof. Failure relief is not automatic.
