What is the meaning of subpoena duces tecum ad testipicandum?

A subpoena duces tecum ad testificandum is a legal order that requires a person to appear in court and bring specified documents or evidence relevant to a case while also testifying. The term combines Latin phrases, where "subpoena duces tecum" means "bring with you" and "ad testificandum" means "to testify." This type of subpoena is often used in legal proceedings to ensure that important evidence is presented alongside witness testimony.
