What safeguards exist for the appearance of witnesses?

• A. Subpoenas are used to compel attendance at trial.
• B. No formal process exists to compel attendance.
• C. Letters from the court inform attendance.
• D. Summons or orders to compel attendance and testify in court.

Answer: (D)

Witness appearance is secured by the court’s power to compel attendance and testimony through formal commands. A summons or court order to appear and testify is issued and binding, with penalties for noncompliance, ensuring witnesses show up and provide the necessary testimony. This mechanism is why the option describing summons or orders to compel attendance and testify in court best fits. A subpoena is a common form of such a command, but the key idea is the formal, enforceable order that ensures participation. Letters from the court alone don’t enforce attendance, and saying there’s no formal process isn’t correct.
