The opinion of the Court was delivered by
There is but one exception to the rule which excludes the implication of a contract where there is an express one, and even' that is an anomaly. Expressum faoit cessare taciturn, is the maxim. Yet it is certainly established by the force of precedent, that where the plaintiff has performed a special agreement to do a particular thing, he may recover the stipulated price of it by an action of indebitatus assumpsit, and use the agreement as evidence of the amount of compensation due. So this court held the law to be in Kelly v. Foster, (2 Binn. 4) on the authority of Alcorn v. Westbrooke (1 Wils. 117), Brooke v. White (4 Bos. & Pul. 330), and of Mr Justice Buller (N.P. 139) who cites Gordon v. Martin (Fitzg. 302) and one or two unreported Nisi Prius cases. “ If the plaintiff,” says hé, “ prove a special agreement and the work done, but not pursuant to such agreement, he shall recover on the quantum meruit, for otherwise he would not be able to recover at ail: as if on a quantum meruit for work and labour, the plaintiff proved he had built a house for the defendant, though the defendant proved there was a special agreement about the building of it, viz., that it should be built in such a time and in such a manner, and that the plaintiff had not performed the agreement, yet the plaintiff would recover on the quantum meruit, though doubtless such proof on the part of the defendant might be proper to lessen the quantum of the damages.” It is settled, therefore, that the price of a service fully performed may be recovered in indebitatus assumpsit; and the reason seems to be that performance of a contract creates a moral duty to compensate it, which is independent of the obligation of the contract, and which is supposed to be a consideration to raise an independent promise by implication. Yet still the duty is only a moral one; and it has long been held that a moral obligation is an insufficient ground of action where a legal obligation' has not been added to it; for certainly, performance of a specialty contract, is not a consideration to raise such a promise; and if it be raised at all by the- naked obligation which springs from performance, it is difficult to see why it should not be raised as an independent promise, as well in the one case as in
But the present is not so much a question of pleading as of title. Can the plaintiff recover in any form of action 1 He can recover, if at all, only in an action founded in contract; but what contract ? There certainly was no aggregatio mentium, or mutual consent, which is of the essence of a contract, that the one might do, and the other should pay for, less than the whole which was contracted to be done. If, then, it will not be pretended that he could recover on the express contract, unless he had performed or was ready to perform every part of it, can it be pretended that the law will imply from part performance a promise for part compensation in the teeth of the fact ? There is no reported instance of such an implication; and'the law is too politic and just, as well as too regardful of the inducements to good faith, to sanction it. The terms of a contract are private laws, which the parties to it prescribe for themselves, to fix the measure of their duties and responsibilities; and they agree to be bound by them and no others. But a judge would bind them differently, did he enforce between them duties of imperfect obligation, and support an implication of terms to which they did not accede. It is the boast of a freeman that he is to be bound only by his own consent; and if there is a power to bind him beyond it, whether exercised by an arbitrator, a judge, a jury, or a populace, it is a despotic
