Trial (law) in the context of "Mock trial"

A bench trial is a trial by judge, as opposed to a jury. The term applies most appropriately to any administrative hearing in relation to a summary offense to distinguish the type of trial. Many legal systems (Roman, Islamic) use bench trials for most or all cases or for certain types of cases.

As a jury renders a verdict, in a bench trial, a judge does the same by making a finding.

Legal proceeding is an activity that seeks to invoke the power of a tribunal in order to enforce a law. Although the term may be defined more broadly or more narrowly as circumstances require, it has been noted that "[t]he term legal proceedings includes proceedings brought by or at the instigation of a public authority, and an appeal against the decision of a court or tribunal". Legal proceedings are generally characterized by an orderly process in which participants or their representatives are able to present evidence in support of their claims, and to argue in favor of particular interpretations of the law, after which a judge, jury, or other trier of fact makes a determination of the factual and legal issues.

• Activities needed to have a court deem legal process to have been provided, such as through service of process.
• Conduct of a trial, whether a lawsuit or civil trial, or a criminal trial.
• Issuance and enforcement of court orders, including those imposing foreclosure or receivership.
• Hearings, particularly administrative hearings.
• Arbitration.

In the United States, Congressional hearings are not generally considered legal proceedings, as they are generally not directed towards the imposition of a penalty against a specific individual for a specific wrong. However, impeachment proceedings are generally conducted as legal proceedings, although experts dispute the question of whether they are primarily legal proceedings, or are merely political proceedings dressed in legal formalities and language. Richard Posner, for example, has asserted that it was "the intent of the framers of the Constitution that an impeachment proceeding be primarily a legal proceeding, akin to a criminal prosecution, rather than a political one".

In law, a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know.

A witness might be compelled to provide testimony in court, before a grand jury, before an administrative tribunal, before a deposition officer, or in a variety of other legal proceedings. A subpoena is a legal document that commands a person to appear at a proceeding. It is used to compel the testimony of a witness in a trial. Usually, it can be issued by a judge or by the lawyer representing the plaintiff or the defendant in a civil trial or by the prosecutor or the defense attorney in a criminal proceeding, or by a government agency. In many jurisdictions, it is compulsory to comply with the subpoena and either take an oath or solemnly affirm to testify truthfully under penalty of perjury.

In evidence law, physical evidence (also called real evidence or material evidence) is any material object that plays some role in the matter that gave rise to the litigation, introduced as evidence in a judicial proceeding (such as a trial) to prove a fact in issue based on the object's physical characteristics.

Public trial or open trial is a trial that is open to the public, as opposed to a secret trial. It should not be confused with a show trial.
