It was therefore necessary for him to aver in his complaint, either a performance of this condition, an excuse for non performance, or a waiver of the condition by the defendants. We find it accordingly alleged in the complaint, that after the written agreement *Page 206 was executed, the defendants promised and agreed with the plaintiff, that they would, within a few days or weeks, furnish and deliver to him some wheels manufactured according to the plan of the patent, or some patterns thereof, in order to enable him to carry out the object of the assignment, and to make a trial of the improvement; but that they wholly neglected and refused to deliver them or either of them, or to provide the plaintiff with any means for making a trial of the improvement, although requested so to do, whereby he was wholly prevented from making such trial, and the assignment was rendered useless to him, and he therefore reassigned the patent to the defendants, and theyaccepted and received the reassignment.
The written agreement contains no provision binding the defendants to furnish the wheels or patterns to make the trial, nor is any consideration for their promise to do so set forth in the complaint, and if this neglect and refusal on the part of the defendants was the foundation of the action, the complaint would be clearly bad, as no cause of action could arise against any party for the neglect or refusal to do an act which he was not bound to perform. This was the view taken of the case by the learned justice who presided at the special term where it was first argued, and although we have not been furnished with any opinion, if any was given, at the general term, I presume that court entertained the same view. With great respect for the two tribunals which have successively passed upon the case, I am compelled to differ from them in the conclusion at which they arrived. Had the plaintiff performed the condition as to the trial of the improvement to the very letter, he would not by that act alone have laid the foundation for recovering back the consideration money from the defendants. It was not on the performance of that condition that the defendants promised to pay back the money, but on the reassignment of the patent. It is true that without performance of the condition the defendants might have refused to accept the reassignment, and then the plaintiff could not have sustained an action against them; but although they might have insisted upon such performance, *Page 207 it is equally true that they could waive it, and accept the reassignment without requiring it, and if they did so waive it, the plaintiff was excused from such performance, and could recover without alleging or proving it. And independent of the question of waiver, if the defendants by their acts prevented the performance by the plaintiff of the conditions of his contract, he was excused from such performance. It is a well settled and salutary rule that a party cannot insist upon a condition precedent, when its non-performance has been caused by himself. (3 John. 531; 14 Wend. 219; 1 Barb. S.C. Rep. 338; 14Mass. Rep. 266; 1 Pick. 287.)
Applying these principles to the complaint demurred to, let us proceed to examine whether it sets out facts sufficient to constitute a cause of action. It sets out the agreement entire, the last clause of which is as follows: "Now then the said Hunter "and Merrill hereby agree that if the said Daniel Young, after "giving the said improvement a thorough trial for the term of "nine months, shall not be able to make the same useful or "profitable to him, he shall be at liberty to reassign the right "so sold to him, and the said Hunter and Merrill, on such reassignment "shall surrender up the said note of thirty dollars, "and pay the above sum of ninety dollars for the said wagon." I have given entire this part of the agreement because the whole case turns upon it. The complaint then shows, that the defendants, who alone had the right to insist that the trial should be made, promised the plaintiff that they would within a few days or weeks furnish him with the requisite materials to make the trial. Upon this promise he relied, and having waited in vain for the delivery of the materials through the whole time stipulated for the trial, (a request for their delivery not having been complied with,) he was prevented from making the trial, and could not ascertain whether the improvement would be useful or profitable. By the act and neglect of the defendants, the plaintiff was prevented from determining the fact, upon the determination of which he was bound to keep the right assigned to him. In this view of the case I regard it as of no importance that the *Page 208 promise of the defendants was without consideration. It is sufficient that the plaintiff in good faith relied upon it, and was thus by their act induced to neglect the strict observance of the conditions of his contract. It does not become the defendants to allege, nor can they be permitted to allege, that their promise should not have been relied upon. The act of a party which prevents the performance of a condition in his favor, is not the less effectual for being gratuitous.
The complaint then further shows, that after the failure (soinduced) to test the value of the patented improvement, the plaintiff executed and delivered to the defendants, a reassignment of the interest which had been assigned to him, which they accepted. By accepting it, with full knowledge that the trial had not been made, they waived the condition requiring it to be made. (1 Barb. 337, 338; 1 Saund. 287, note 16.) The defendants thus by their own consent became repossessed of all the interest which they had parted with, and by the terms of their agreement the plaintiff's right to recover back the consideration which he had paid became complete.
It might also with propriety be said, that by accepting the reassignment with its recitals, the defendants admitted that the plaintiff was prevented by their acts from performing the conditions of his contract, and that his excuse for non-performance was sufficient. I think the complaint sets forth a good cause of action, and that the plaintiff is entitled to judgment in his favor. This will do complete justice between the parties. The defendants have received back what they parted with, and the plaintiff will recover what he paid, the consideration for which has failed through the fault of the defendants. The judgments of the general and special term should be reversed, and judgment rendered in favor of the plaintiff.
