Adjudication is the formal process by which a legal body resolves a dispute or determines a question of law. A judge hears arguments, evaluates evidence, applies legal rules, and issues a decision that binds the parties. The decision becomes part of the legal record and, in common law systems, may bind future courts through precedent.
Adjudication is distinguished from other forms of dispute resolution by its institutional character. Negotiation is bilateral — the parties work it out themselves. Mediation introduces a third party who facilitates agreement but can’t impose one. Arbitration introduces a third party who can impose a decision, but by agreement of the parties rather than by state authority. Adjudication is backed by the state: the court’s decision is enforceable through the state’s coercive apparatus (fines, imprisonment, seizure of assets).
This state backing is what gives adjudication its formatting power. Because court decisions are enforceable, they don’t just resolve the immediate dispute — they establish facts that other institutions treat as authoritative. When a court rules that a particular institutional practice constitutes evidence of good faith, that ruling reshapes institutional behavior beyond the parties to the case. The adjudicatory process produces legal formatting as a structural effect, not just a resolution of the dispute at hand.
Most legal disputes never reach adjudication. In American criminal law, roughly 95% of cases are resolved through plea bargaining — negotiated agreements between prosecutors and defendants that bypass the trial process entirely. In civil law, settlement is the norm. This means that the adjudicatory process, while formally central to the legal system, is statistically marginal. Its influence operates primarily through the shadow it casts: parties negotiate in light of what they expect a court would decide if the case went to trial.
