Who may be subpoenaed to appear under a subpoena?

A subpoena is a legal document that orders an individual to appear in court or produce documents for a legal proceeding. The correct answer, which states that anyone, including non-criminals, may be subpoenaed, reflects the broad applicability of subpoena power.

In practice, this means that individuals who have relevant information or documents related to a case can be called upon, regardless of their criminal status or relationship to the parties involved. This can include witnesses, expert consultants, and even those who may not have a direct involvement in the case but possess useful knowledge.

The other options incorrectly limit the scope of who can be subpoenaed. Some suggest that only certain groups, such as convicted criminals or government officials, can be compelled to appear, which is not accurate as many types of individuals can be required to testify or produce documents, making the legal system more inclusive and ensuring that all relevant information can be obtained.
