§ 25-1919.Appeal; briefs; rules; plain error.

Section 25-1919 assigns the Supreme Court the job of writing the briefing rules for every case appealed to the Court of Appeals or the Supreme Court. Those rules, not a separate petition in error or freestanding assignment of errors, govern how a party presents a claim that a judgment, decree, or final order should be reversed, vacated, or modified.

The appellant carries the burden of particularity. The brief has to set out each error the appellant intends to press for reversal, vacation, or modification, and no additional document listing those errors is required beyond what the brief already contains. A brief that buries or omits an error risks losing it, since the rule ties the scope of appellate argument to what the brief itself identifies.

The section leaves one escape hatch for the appellate court itself. The Court of Appeals or Supreme Court may, at its own option, take up a plain error even though the appellant’s brief never mentioned it. That option belongs to the court, not to the parties — a litigant cannot demand that the court reach an unbriefed error, only hope the court exercises the discretion the section allows.
