Subpoena ad testificandum is used for what purpose?

Subpoena ad testificandum is specifically designed to command the appearance of a witness to testify in a legal proceeding. This type of subpoena compels an individual to appear in court or at a deposition to provide oral testimony regarding a matter pertinent to the case being heard.

This legal tool is fundamental in judicial processes, ensuring that individuals who possess relevant information can be brought before a court to provide their accounts or insights. By calling witnesses, the court can gather firsthand information that may be crucial for judging the facts and reaching a fair decision in a case.

Other options pertain to different legal processes: disclosing financial records relates to subpoenas duces tecum, which require the production of documents; issuing a search warrant is a law enforcement tool used to authorize searching a location for evidence; and summoning evidence for inspection also correlates with document production rather than witness appearances. Each option serves its unique purpose within the legal system, but the correct answer is specifically focused on the function of compelling witness testimony.
