New York State - Civil Rights - CVR - Article 3 - Section 24
§ 24. Privilege from arrest of officers of courts of record. An officer of a court of record, appointed or elected pursuant to law, is privileged from arrest, during the actual sitting, which he is required to attend, of a term of the court of which he is an officer, and no longer; but an attorney or counselor is not thus privileged, unless he is employed in a cause, to be heard at that term.
