Privileges from testifying for members of the General Assembly are found in § 9-122 of the Courts Article. Provisions relating to civil immunity for acts and omissions in the performance of constituent services by members of the General Assembly are found in § 5-525 and § 5-526 of the Courts Article.

Papers, books, accounts, documents, testimony, and records sought in accordance with a subpoena issued under § 2–408, § 2–507, § 2–807, § 2–1104, or § 2–1608 of this title in connection with a lawfully authorized legislative inquiry or examination must be pertinent to the inquiry or examination. For purposes of subsection (a) of this section, papers, books, accounts, documents, testimony, or records are considered pertinent if they: relate to the matters under inquiry or examination; assist in assessing the credibility of a witness; contradict or corroborate the testimony of a witness; or demonstrate the existence of undue influence on a witness.

This section applies to a petition for an order directing compliance with a subpoena or compelling testimony under § 2–408, § 2–507, § 2–807, or § 2–1104 of this title. The petition shall be filed in the Circuit Court for Anne Arundel County or, at the election of the petitioner, in any county in which venue would be appropriate under § 6–201 of the Courts Article. Except as otherwise provided in this subsection, the petition shall set forth the questions or requests that were asked or made of the party whose conduct necessitated the petition and, if any, the answers or objections provided or raised by that party. The petitioner may satisfy the provisions of paragraph (1) of this subsection by attaching the relevant portions of a transcript to the petition. The petitioner need not comply with the provisions of paragraph (1) of this subsection if there has been no response to the subpoena. Any response to the petition shall be filed by the party served with the petition within 15 days after being served with the petition, unless that time period is shortened by order of the court. A response to a petition filed by the party whose conduct necessitated the petition is the only pleading that an objecting party may file to object to a subpoena. The party whose conduct necessitated the petition may not file a motion to quash or a petition for an injunction with respect to the subpoena. Except for cases that the court considers to require a higher priority, a proceeding under this section, including any subsequent appellate judicial review, shall: take precedence on the court’s docket; be heard at the earliest practicable date; and be expedited in every way. In any hearing on the petition in a proceeding under this section, the court may not allow any additional evidence. Notwithstanding any other provision of law, a party to a proceeding under this section may appeal the decision of the circuit court only by a petition to the Supreme Court of Maryland for the issuance of a writ of certiorari.
