¶1The court below refused to permit the defendants to show that the work for which the plaintiff had obtained a lien was unskillfully performed, although this was set up in the answer as' a ground of defence; and the return states, that the ground of the objection to this evidence was, that the defendants had not served a bill of particulars of any offset, pursuant to the 5th section of the act of 1851, “for the security of mechanics,” &c., under which this proceeding was instituted. I think the decision was founded in an erroneous view of the nature of the defence thus attempted to be proved, or in a misapprehension of the effect of the section of the statute referred to.
¶2The plaintiff had agreed to perform certain work and labor, as a carpenter and joiner, in a good, substantial, and workmanlike manner; he had brought his action for the money due for that work, in effect, by his notice of claim averring performance of his agreement. The defendants denied all the plaintiff’s allegations, and sought to prove that the work was not done in a good, substantial, and workmanlike manner. This was no attempt to prove a set off. The defence went to the whole ground of action. It tended to show that nothing was due, because the plaintiff had not performed his agreement. The act in question does not require that a statement of such a defence shall be made in any bill of particulars, or other paper, to be served before the appearance of the parties. It *699is not the subject of a bill of particulars. It is only when a set of is claimed that the defendant is, by the statute, required to serve a bill of particulars.
¶3Again, the defence was competent under the pleadings, by way of recoupment, i. e., not as a set off against the plaintiff’s claim, but as an abatement from the contract price, by reason of imperfection in the work done under the contract. Recoupment and set off are so widely different in their nature, that we cannot suppose that the legislature intended to embrace both in the one well understood term, “ offset.” Upon either or both of these grounds, therefore, the testimony ought to have been received.
¶4The defect in the notice of appeal having been waived by express stipulation, the judgment must be reversed.
¶5Judgment reversed.
