How is "subpoena" defined as per the CCP?

The definition of "subpoena" as provided in the Code of Criminal Procedure refers to a legal document that orders an individual to appear in court or produce documents or evidence in a legal proceeding. This concept is crucial for ensuring that witnesses can be compelled to testify and that relevant information can be obtained, which is fundamental to the judicial process.

This is distinctly different from the other options. For instance, a warning issued to a suspect does not carry the legal authority of a subpoena and does not require the individual to appear in court. Similarly, a request for evidence may simply be an informal appeal or request that does not have the binding legal force of a subpoena. Lastly, a form of legal representation refers to the legal counsel provided to a defendant or party in a case, which is an entirely separate legal concept. The correct understanding of a subpoena is vital for comprehending how legal proceedings operate and how evidence and testimony are obtained in the criminal justice system.
