Protection: members of Department acting in pursuance of a warrant

When any action is brought against any police officer, for any act done in obedience to the warrant of any magistrate, he shall not be responsible for any irregularity in its issue or form, or for any want of jurisdiction of the magistrate issuing the same, but may plead the general issue, and give the warrant in evidence at the trial, and on proving that the signature is in the handwriting of the person whose name appears subscribed thereto, and that he was reputed to be and acted as magistrate, there shall be a verdict for the defendant.
