A bench trial is a trial decided by a judge alone, without a jury. A jury trial is decided by a panel of citizens. The choice between them — where one exists — is among the most consequential strategic decisions in litigation, with implications that reach from legal theory to psychology to the specific facts of the case. What They Are In a jury trial, the jury is the finder of fact.

A motion in limine is a pretrial request asking the court to rule on the admissibility of specific evidence before it is presented at trial. The goal is to prevent the jury from hearing evidence that the moving party believes is improper — and to avoid the prejudice that comes from a jury hearing something it is then told to disregard. What It Is Trials proceed under rules of evidence that determine what a jury can and cannot hear.

Nolle prosequi — Latin for “to be unwilling to prosecute” — is the formal declaration by a prosecutor that they are dropping criminal charges.

Voir dire is the process by which attorneys and judges question prospective jurors before a trial to assess their suitability to serve.

What It Is Before a jury trial begins, a pool of prospective jurors — the venire — is summoned to the courthouse.

A writ of mandamus is a court order commanding a government official, lower court, or government body to perform a duty that is purely ministerial — one that the law requires them to perform and that they have refused or failed to carry out. It is an extraordinary remedy, not a routine one, and courts grant it sparingly. What It Is Mandamus sits in the category of extraordinary writs — legal tools that exist outside the normal appellate process and are available only when ordinary remedies are inadequate.
