In popular culture, an “era” marks a defined creative period that is cohesive, finite, and governed by its own rules. Taylor Swift’s Eras Tour captures that idea vividly: each chapter has its own rules, aesthetic, and boundaries. Litigation follows a similar arc. Trial marks the end of one era, but an appeal is not an encore. It is an entirely new era, shaped by different objectives, different constraints, and a different decision-maker. Appreciating that transition is essential to effective appellate practice.

The End of the Trial Era: Procedural Rules Regarding Appealability and Jurisdiction

The appellate era begins only after the conclusion of the trial court phase with the entry of an appealable judgment or order. In California, appealability is strictly statutory, most commonly governed by California Code of Civil Procedure section 904.1. Absent statutory authorization, the Court of Appeal lacks jurisdiction to proceed.[i] The transition into the appellate forum is effectuated through the filing of a notice of appeal, the timeliness of which is jurisdictional. In most civil cases, the notice must be filed within 60 days after service of a notice of entry of judgment, or within 180 days after entry of judgment if no notice is served.[ii] An untimely notice of appeal is an absolute bar to review and requires dismissal.[iii]

Setting the Boundaries: The Record on Appeal

Once the notice of appeal is filed, the scope of the appellate era is fixed by the record. Unlike trial proceedings, the appellate process permits no expansion or supplementation of the evidentiary landscape. The appellant bears the burden of providing an adequate record demonstrating reversible error, typically through a clerk’s transcript, reporter’s transcript, or authorized alternative.[iv] Issues unsupported by citations to the record are forfeited, and matters outside the record are disregarded.[v] This limitation reflects the appellate court’s role: to review the trial court’s rulings, not to reconsider factual determinations or entertain new evidence.[vi]

The Core of the Appeal: Briefing and Standards of Review

Briefing represents the substantive heart of the appellate process. The California Rules of Court impose detailed requirements governing the content, formatting, and citation of appellate briefs.[vii] The appellant’s opening brief must identify each alleged error and support it with reasoned legal analysis, citations to the record, and relevant authority. Arguments that are conclusory or unsupported may be deemed waived.[viii] Throughout briefing, the applicable standard of review—whether de novo, abuse of discretion, or substantial evidence—frames the court’s analysis and often proves outcome-determinative.[ix]

Limited Presentation: Oral Argument and Submission

Oral argument, when granted, is not an opportunity to retry the case or introduce new theories. Rather, it allows counsel to respond to the appellate court panel’s questions and clarify issues already presented in the briefs.[x] The Court of Appeal may decide a case with or without oral argument, and the matter is deemed submitted once argument concludes or is waived.

Resolution and Finality: Opinion and Remittitur

The appellate era concludes with the court’s written decision. Published opinions constitute binding precedent, while unpublished opinions generally may not be cited, subject to limited exceptions.[xi] Finality follows quickly: absent rehearing or review, the decision becomes final 30 days after filing, and the remittitur issues, returning jurisdiction to the trial court and formally ending the appeal.[xii]

Practice Tips for the Appellate Era

Effective appellate advocacy requires a recalibrated approach. Practitioners should assess deadlines immediately upon judgment, designate a complete and accurate record, and frame arguments around the governing standard of review. Precision matters more than volume; fewer, well-developed issues are often more persuasive than numerous marginal claims. Finally, counsel should remember that appellate courts presume the correctness of the judgment, requiring that error must be affirmatively demonstrated rather than merely asserted.

In conclusion, every appeal represents a transition from one defined era to the next. Just as creative eras have distinct rules, tones, and boundaries, the appellate era operates under constraints fundamentally different from those of trial. The live performance of the courtroom gives way to a fixed record, written advocacy, and structured review, in which precision and restraint outweigh dramatic flourish. Viewing an appeal as a new era, rather than an encore, helps practitioners shed trial-level instincts and adopt the discipline appellate courts expect. Practitioners who recognize the shift, respect the rules governing this phase, and adjust their approach accordingly are best positioned to navigate the life of an appeal successfully and bring the case to its proper close.
