The Rev. Sts. c. 97, §§ 44, 45, expressly declare that no person shall be imprisoned on mesne process or execution for any debt less than five dollars, or on any execution issued upon a judgment rendered upon a former judgment founded upon such a debt. And the forms of all executions are required to be so varied as to adapt them to that prohibition. I) 47. In view of these provisions, there can be no doubt that the command, contained in the execution which was issued by *572Jones against the plaintiff, to take the body of the plaintiff and commit him to the Commonwealth’s jail, was a direct violation of the positive requirements of the law. This is not denied by the defendants. But their defence is placed by them on a wholly different ground. They insist that, in framing and issuing the execution, Jones acted in his judicial capacity as a justice of the peace, and for that reason is not responsible in any civil action to the plaintiff for any injurious consequences resulting from it.
If the position assumed by the defendants could be maintained as a matter of fact, the consequence contended for by them would undoubtedly follow. There is a familiar and well known distinction between the judicial and ministerial powers and duties of justices of the peace. When acting in the former capacity, and within the limits of the jurisdiction conferred upon them, like the judges of other courts, they are exempted from liability to answer elsewhere in private actions for their official orders, decrees and judgments. Pratt v. Gardner, 2 Cush. 63. But they have always been held responsible to individuals in civil suits for all the injurious consequences arising from every illegal act they may have done, either in the adjudication of causes of which they had no jurisdiction, or in the exercise of their ministerial powers, or in the discharge of their ministerial duties. Briggs v. Wardwell, 10 Mass. 357. Percival v. Jones, 2 Johns. Cas. 49. Spencer v. Perry, 17 Maine, 413, Clarke v. May, ante, 410.
When, in the progress of a suit, a final judgment has been rendered, there can remain no further judicial duty to be performed. The court or magistrate has then no longer a question upon which to deliberate, or a cause between contending parties to decide. Nothing is left to be done but to carry the judgment into effect. That, under our law, is accomplished by means of an execution. It was early determined by this court that the issuing of such execution by a justice of the peace was merely a ministerial act; and in a particular instance, where such process was issued erroneously, the magistrate was held responsible in damages for the commitment to prison of a party under it. *573Briggs v. Wardwell, 10 Mass. 356. This decision has never been brought into question; but, ever since it was made, has been acquiesced in and respected. Blanchard v. Waters, 10 Met. 185. The case of Kendall v. Powers, 4 Met. 553, may be cited as an instance in which the doctrine laid down in Briggs v. Ward-well, that a magistrate is liable to a party in a civil action for damages resulting to him from the illegal issuing of a final process upon a judgment rendered, was considered, both by the counsel of the parties, and by the court, so familiarly and firmly established, that it was not even adverted to as presenting any possible question for inquiry or debate.
It is a necessary consequence of this doctrine that no defence can be made by Jones in this action. Nor has Russell shown any at all. The jury, under proper directions from the court, have found that he procured the execution to be issued in the illegal form in which it was issued by the magistrate, and caused it afterwards to be enforced, by the commitment of the plaintiff to the common jail, knowing at the time that the statute absolutely prohibited the imprisonment of the judgment debtor. He thus cooperated with the magistrate in the illegal act. The imprisonment of the plaintiff upon the execution was the result of action on the part of both of the defendants. Each contributed his share of the means by which it was effected. They were therefore joint trespassers in the unlawful act, and jointly responsible for its consequences. Exceptions overruled.
