“With regard to a former adjudication, in case you find for the defendant on that plea, a further inquiry will be unnecessary. Upon this point you are instructed that if you find the labor and materials furnished, for which pay is claimed in this suit, is the same labor and material furnished in the building of the house described in the proceedings in the former suit, yet if, up to and at the time of the former suit, the defendant had refused to accept the *376bouse, and that he has since entered into and taken possession of the house, the former adjudication will not preclude the plaintiff in this suit from recovering what the labor and materials furnished were worth, less all damages for a failure to complete the house according to the terms of the contract, and also less all payments made on the contract.”
¶2The giving of this instruction, and the refusal of those asked by the defense, are assigned for error. Now, it will be observed, that the court recognized the doctrine of a former adjudication as a good defense, and did not, in all probability, reject the defendant’s instructions, because they did not contain the law in its usual application upon that subject, but because they had been drawn without reference to the supposed altered position of the parties and the particular circumstances of the case. The records of the former suit have been made evidence in this, and was before the court. From these it appeared that the court, in its charge to the jury in the first suit, made the nonacceptance of the work by the defendant (because not done according to contract) a prominent reason why the plaintiff should not recover anything in that action. Since then it is said the defendant has concluded to accept, enter into possession of, and enjoy the use of said house. This, we suppose, in the mind of the court, introduced a new element in the controversy, and so changed the relative rights and condition of the parties as to afford a new cause of action ; assimilating it perhaps, in principle, to the case where suit had been brought upon a note before maturity, the plaintiff fails because no cause of action had accrued, but a subsequent suit would not be barred on that account, upon the same note when due. So a special contract to build a house for a given price would not, at least at common law, be the ground of an action in favor of the builder until he had performed his contract in the manner and style stipulated. But the difficulty of the instruction given by the court *377aboye set forth, and which is excepted to, is, that it confounds the ordinary use and possession of the house in question by the defendant, with the true legal idea of an acceptance. If there was such an acceptance, then we are of the opinion that this second suit for the same cause of action may, under the circumstances of this case, be maintained ; but such acceptance is not manifested alone by use and occupation, for the reason that the house was built upon the defendant’s land, became incorporated with the realty, and the property thereof vested nolens volens in him. He had no choice but to use it, whether built according to contract or not, and such use, under protest, accompanied with complaint that the contract had not been performed by the undertaker, would not be a waiver of his right to insist upon the due execution of the contract. Whereas, on the other hand, if he should take possession without objection, making no complaint, or under any other circumstances indicating acquiescence, it would be deemed a waiver of the non-execution of the contract, and evidence of an acceptance. The rule upon this subject, which commends itself to our favor and approval, is very well stated and laid down in the case of Wilson v. School District No. 4, 32 N. H. R., 118. Now, the instruction under consideration fails to present to the jury, as it should have done in our opinion, the distinction between possession and acceptance as above explained, and to that extent is faulty and erroneous. Yet we are not impressed with the idea, in looking through the whole record, that any substantial prejudice or injustice has been done to the rights of the defense, and it may be, under the requirements of § 2978, we would be justified in overlooking the same. Still, as we must reverse this case upon another and distinct question, it is proper we should point out the irregularity, that it may be avoided in a subsequent trial, should one occur.
