What is the primary purpose of a subpoena?

The primary purpose of a subpoena is to order a witness to appear and testify. In legal proceedings, a subpoena serves as a formal command issued by a court or legal authority requiring an individual to provide testimony or produce evidence, such as documents or records, relevant to a case. This mechanism ensures that the judicial process can access pertinent information and witness accounts, which are crucial for determining the facts of the case.

For example, in a trial, the testimony of witnesses can significantly impact the outcome, making the subpoena an essential tool for gathering evidence and ensuring that all relevant voices are heard. By compelling individuals to appear, a subpoena enhances the integrity of the judicial system by ensuring that available information is not withheld.

The other options do not accurately describe the purpose of a subpoena. Dismissing a case, granting immunity, or establishing evidence as admissible are different legal functions that serve distinct roles in the legal process. The subpoena directly relates to the summoning of individuals to provide testimony, highlighting its critical role in facilitating justice.
