Source of the Obligation.—The question of the nature and source of the obligation of a contract, which went by default in Fletcher v. Peck and the Dartmouth College case, with such vastly important consequences, had eventually to be met and answered by the Court in connection with private contracts. The first case involving such a contract to reach the Supreme Court was Sturges v. Crowninshield[1694] in which a debtor sought escape behind a State insolvency act of later date than his note. The act was held inoperative; but whether this was because of its retroaction in this particular case or for the broader reason that it assumed to excuse debtors from their promises, was not at the time made clear. As noted earlier, Chief Justice Marshall's definition on this occasion of the obligation of a contract as the law which binds the parties to perform their undertakings was not free from ambiguity, owing to the uncertain connotation of the term law.
Ogden v. Saunders.—These obscurities were finally cleared up for most cases in Ogden v. Saunders,[1695] in which the temporal relation of the statute and the contract involved was exactly reversed—the former antedating the latter. Marshall contended, but unsuccessfully, that the statute was void, inasmuch as it purported to release the debtor from that original, intrinsic obligation which always attaches under natural law to the acts of free agents. "When," he wrote, "we advert to the course of reading generally pursued by American statesmen in early life, we must suppose that the framers of our Constitution were intimately acquainted with the writings of those wise and learned men whose treatises on the laws of nature and nations have guided public opinion on the subjects of obligation and contract," and that they took their views on these subjects from those sources. He also posed the question of what would happen to the obligation of contracts clause if States might pass acts declaring that all contracts made subsequently thereto should be subject to legislative control.[1696]
For the first and only time majority of the Court abandoned the Chief Justice's leadership. Speaking by Justice Washington it held that the obligation of private contracts is derived from the municipal law—State statutes and judicial decisions—and that the inhibition of article I, section 10, is confined to legislative acts made after the contracts affected by them, with one exception. For by a curiously complicated line of reasoning it was also held in this same case that when the creditor is a nonresident, then a State may not by an insolvent law rights under a contract, albeit one of later date.
With the proposition established that the obligation of a private contract comes from the municipal law in existence when the contract is made, a further question presents itself, namely, what part of the municipal law is referred to? No doubt, the law which determines the validity of the contract itself is a part of such law. Also, the law which interprets the terms used in the contract, or which supplies certain terms when others are used; as for instance, constitutional provisions or statutes which determine what is "legal tender" for the payment of debts; or judicial decisions which construe the term "for value received" as used in a promissory note, and so on. In short, any law which at the time of the making of a contract goes to measure the rights and duties of the parties to it in relation to each other enters into its obligation.
Remedy a Part of the Obligation
Suppose, however, that one of the parties to a contract fails to live up to his obligation as thus determined. The contract itself may now be regarded as at an end; but the injured party, nevertheless, has a new set of rights in its stead, those which are furnished him by the remedial law, including the law of procedure. In the case of a mortgage, he may foreclose; in the case of a promissory note, he may sue; in certain cases, he may demand specific performance. Hence the further question arises, whether this remedial law is to be considered a part of the law supplying the obligation of contracts. Originally, the predominating opinion was negative, since as we have just seen, this law does not really come into operation until the contract has been broken. Yet it is obvious that the sanction which this law lends to contracts is extremely important—indeed, indispensable. In due course it became the accepted doctrine that that part of the law which supplies one party to a contract with a remedy if the other party does not live up to his agreement, as authoritatively interpreted, entered into the "obligation of contracts" in the constitutional sense of this term, and so might not be altered to the material weakening of existing contracts. In the court's own words, "Nothing can be more material to the obligation than the means of enforcement. Without the remedy the contract may, indeed, in the sense of the law, be said not to exist, and its obligation to fall within the class of those moral and social duties which depend for their fulfillment wholly upon the will of the individual. The ideas of validity and remedy are inseparable, * * *"[1697]
Establishment Of The Rules.—This rule was first definitely announced in 1843 in the case of Bronson v. Kinzie.[1698] Here an Illinois mortgage giving the mortgagee an unrestricted power of sale in case of the mortgagor's fault was involved, along with a later act of the legislature which required mortgaged premises to be sold for not less than two-thirds of the appraised value, and allowed the mortgagor a year after the sale to redeem them. It was held that the statute, in altering the preexisting remedies to such an extent, violated the constitutional prohibition, and hence was void. The year following a like ruling was made in the case of McCracken v. Hayward[1699] as to a statutory provision that personal property should not be sold under execution for less than two-thirds of its appraised value.
Qualifications Of The Rule.—But the rule illustrated by these cases does not signify that a State may make no changes in its remedial or procedural law which affect existing contracts. "Provided," the Court has said, "a substantial or efficacious remedy remains or is given, by means of which a party can enforce his rights under the contract, the Legislature may modify or change existing remedies or prescribe new modes of procedure."[1700] Thus States are constantly remodelling their judicial systems and modes of practice unembarrassed by the obligation of contracts clause.[1701] The right of a State to abolish imprisonment for debt was early asserted.[1702] Again the right of a State to shorten the time for the bringing of actions has been affirmed even as to existing causes of action, but with the proviso added that a reasonable time must be left for the bringing of such actions.[1703] On the other hand, a statute which withdrew the judicial power to enforce satisfaction of a certain class of judgments by mandamus was held invalid.[1704] In the words of the Court: "Every case must be determined upon its own circumstances;"[1705] and it later added: "In all such cases the question becomes, * * *, one of reasonableness, and of that the legislature is primarily the judge."[1706]
