Trial
A formal proceeding to resolve disputes through evidence and adjudication.
A trial is a formal proceeding in which parties to a dispute present evidence before a tribunal, such as a judge, jury, or other designated trier of fact, with the authority to adjudicate claims. Trials aim to resolve disputes and are categorized by the finder of fact (e.g., jury trial or bench trial) and by the type of dispute (e.g., criminal, civil, administrative, or labor).

Lore & Background
Trials are held before a tribunal, which may be a court or other formal setting. In a jury trial, a group of community members decides the facts; in a bench trial, a judge alone decides. Hearings before administrative bodies share many trial features but are not typically called trials, and appeals are generally not deemed trials as they review prior evidence without introducing new evidence. Criminal trials resolve accusations by a government against a person accused of a crime, with broad rights for the accused. Civil trials settle non-criminal disputes, and administrative trials revise administrative hearings under administrative law. Labor law addresses rights of workers and their organizations, with government agencies enforcing standards. Common law systems use an adversarial approach, where prosecution and defense present evidence before a neutral judge and sometimes a jury. Civil law systems use an inquisitorial approach, where an examining magistrate investigates and conducts the trial. A mistrial may be declared due to jurisdictional issues, improper evidence, misconduct, hung jury, juror disqualification, or illness of a juror or attorney.
Reader's Guide
Trials are a cornerstone of legal systems worldwide, providing a structured method for resolving disputes and determining guilt or innocence. The distinction between adversarial and inquisitorial systems reflects different philosophies: the adversarial system assumes truth emerges from open contest, while the inquisitorial system relies on impartial investigation. Both have critics—adversarial systems may prioritize winning over truth and be affected by resource inequalities, while inquisitorial systems concentrate power in a single magistrate, limiting appeal opportunities. Trials also serve as a check on government power, particularly in criminal cases where the state seeks to deprive individuals of life, liberty, or property. The possibility of a mistrial ensures fairness when procedural errors or deadlocks occur. Beyond courts, trials appear in contexts like impeachment proceedings and historical practices such as trial by ordeal or combat. The rules of procedure—criminal, civil, or administrative—govern each type, shaping how evidence is presented and disputes resolved.
Did You Know?
- A trial held before a group of community members is called a jury trial; one held solely before a judge is a bench trial.
- An appeal is generally not deemed a trial because it usually reviews prior evidence without introducing new evidence.
- A judge may declare a mistrial due to a hung jury that cannot reach a verdict with the required degree of unanimity.
- In common law systems, the adversarial approach assumes truth emerges from open contest between prosecution and defense.
Frequently Asked Questions
What is a trial in the legal system?
A trial is a formal, structured proceeding where the parties in a dispute present their evidence before a designated decision-maker—such as a judge, jury, or other trier of fact—who then adjudicates the claims and resolves the matter.
What are the main types of trials?
Trials are typically classified by the nature of the dispute into criminal, civil, administrative, or labor proceedings, and further distinguished by whether a jury or a judge (bench trial) serves as the finder of fact.
Who actually decides the outcome in a trial?
The decision rests with the designated trier of fact, which can be a judge sitting alone, a jury of peers, or another authorized body, depending on the jurisdiction and the category of case.
What can happen at the end of a trial?
A trial generally concludes with a verdict in which the trier of fact rules on the claims, though a mistrial may also result if procedural issues prevent a definitive resolution.
How do legal systems differ in how they run trials?
The two dominant frameworks are the adversarial model common in common-law countries, where opposing sides present competing cases, and the inquisitorial model typical of civil-law systems, where the judge takes a more active role in investigating the facts.
