Adversarial System
An adversarial system is a legal process in which opposing parties present evidence and arguments to a neutral judge or jury, who decides the dispute under the law. The judge manages the process and applies legal rules, while the parties generally frame the issues they ask the court to resolve.

Example: In United States v. Sineneng-Smith (2020), the Supreme Court emphasized the party-presentation principle and criticized a court of appeals for deciding a case on theories the parties had not presented.
Common misconception: An adversarial system means the judge has no role in ensuring fairness. Judges manage proceedings, rule on evidence and law, and protect the integrity of the process.
