protection does not extend to cases where they have acted either maliciously and without reasonable and probable cause
"Wherever protection of the exercise of judicial powers applies, it is so absolute that no allegation that the acts or words complained of were done or spoken mala fide, maliciously, corruptly, or without reasonable or probable cause suffices to found an action." Further it has been pointed out under the title "Liability of Magistrates" at page 160 of Volume 25 of Halsbury's Laws of England, 3rd Edition, that -
"Protection is afforded by common law and by statute to justices in respect of acts done in the execution of their duty as such; but this protection does not extend to cases where they have acted either maliciously and without reasonable and probable cause, or without or in excess of their jurisdiction, and in such cases they are liable to an action for damages at the suit of the party "aggrieved," A similar passage occurs at page 768 of Volume 38 of the Halsbury's Laws of England, 3rd Edition - A Magistrate or other person acting In a judicial capacity is not liable for acts done within his jurisdiction, but he is liable to an action for false imprisonment If he unlawfully commits a person to prison in a matter in which he has no jurisdiction, provided that he has knowledge, or the means of knowledge of the facts which show that he has no jurisdiction.
