The opinion of the Court was delivered by

Prentiss, J.

The horse for which this action was brought, was taken by the defendants, under an execution, issued on a judgment recovered in a suit against the plaintiff, by the selectmen of Acton. It was objected on the trial, and is now insisted, that the judgment and execution were irregular and void, and afforded no justification to the defendants.

It is unnecessary to give any opinion, whether the action in which the judgment was recovered against the plaintiff, could have been properly maintained in the name of the selectmen, or should have been brought in the name of the town; because it is very clear, that the question could not be raised in this case. Admitting that the action should have been brought in the name of the town, and that the selectmen could not maintain it, the proceedings are merely erroneous, and not void. The judgment, while it remains in force and unreversed, is conclusive upon the parties, and its merits cannot be overhauled, nor can it be impeached, in this collateral way.

It is equally unnecessary to determine, whether the nature and purpose of the action against the plaintiff were such, as to ¡require a minute in writing on the original writ, under the official signature of the Justice, of the day, month and year, when the writ was presented to, and signed by him. We are inclined to think, that such minute was not requisite, but it is quite unnecessary to enter at all into that question. The execution issued against the plaintiff was warranted by the judgment, and unless that was ipso facto void, and a nullity ah initio, the execution affords a good justification to the defendants. The statute which is relied upon, declares, that every original writ, issued in the cases therein mentioned, in which a minute is not made and signed as therein required, shall be void. The statute does not, in terms, extend to the judgment, which may be rendered in the suit commenced by such writ; but it is argued, that as the writ is made void, the judgment, and all the proceedings consequent upon it, must be void also. It would certainly be going great lengths to hold, that the party, after judgment is rendered against him in such case, may treat the judgment as a *251nullity, and the plaintiff, if he sues out execution upon it, as a trespasser. This would be manifestly inconsistent with the general rules of law, as to the conclusive nature of judgments, The doctrine which prevails in the books, is, that a record is of so high a nature, that it cannot be impugned by the parties to it in any collateral proceeding. If a judgment has been irregularly obtained, it is nevertheless a judgment to all intents and purposes, until set aside or vacated. (Phillips vs. Biron, Stra. 509. Hammond's N. P. 54.) It is often the case, that a statute which declares a thing to be void, is to be construed as making it voidable merely at the instance of the party; and it would seem, that where the statute only declares the original writ void, and is silent as to the judgment, the reasonable construction is, that it is net void, but voidable merely, that is, may be rendered void by plea, or other proper proceeding. The case of Prigg vs. Adams, 2 Salk. 674, is a very strong authority, and entirely decisive of the point in question. In trespass and false imprisonment, the defendant justified as an officer, under a ca. sa. on a judgment in the Common Pleas, upon a verdict of five shillings, for a cause of action arising in Bristol. The plaintiff replied the private act of Parliament for erecting the Court of Conscience in Bristol, wherein was a clause, that if any person bring such-action in any of the courts at Westminster, and it appeared upon trial to be under forty shillings, that no judgment should be entered for the plaintiff: and that if it be entered, that it shall be void. Upon demurrer, the question was, whether the judgment was so far void, that the party should take advantage of it in this collateral action. The court held, that it was not void, but voidable only, by plea or writ of error. The general principle certainly is, that a judgment can be considered void in no case, except where it appears from the judgment itself that the court had no jurisdiction. It may be voidable, but not void, if rendered by a court of competent jurisdiction; and until it is set aside or vacated, it forms a good justification for the proceedings had to enforce it. When an irregular judgment has been set aside, the consequences, as it respects the parties to it, are the same as if no judgment had ever existed ; but an erroneous judgment, though afterwards reversed, will afford a protection for all acts done under it.
