38 Opinion of the Court. Maurice J. O'Sullivan argued the cause and filed a brief for appellant. Daniel L. Brenner submitted on brief for appellee. MR. JUSTICE DOUGLAS delivered the opinion of the Court. Missouri has a statute which limits the life of a judgment to ten years after its original rendition or ten years after its revival.' Missouri also provides that no judgment can be revived after ten years from its rendition.* These provisions are applicable to all judgments whether rendered by a Missouri court or by any other court. Petitioner has a Colorado judgment against respondent. It was obtained in 1927 and revived in Colorado in 1945 on personal service upon respondent in Missouri. Suit was then brought in Missouri on the revived Colorado judgment. The Supreme Court of Missouri, though assuming that the judgment was valid in Colorado, refused to enforce it because the original judgment under Missouri's law could not have been revived in 1945. It held that the lex fori governs the limitations of actions and that the Full Faith and Credit Clause of the Constitution, Art. IV, § 1, did not require Missouri to recognize Colorado's more lenient policy as respects revival of judgments. 358 Mo. 65, 213 S. W. 2d 416. 1. Petitioner sought to bring the case here by appeal. But we postponed the question of jurisdiction to the merits. Certiorari, not appeal, is the route by which the question whether or not full faith and credit has been given a foreign judgment is brought here. Roche v. McDonald, 275 U. S. 449; Morris v. Jones, 329 U. S. 545. 11 Rev. Stat. Mo. 1939, § 1038. 21 Rev. Stat. Mo. 1939, § 1271. 1 Colo. Stat. Ann. 1935, c. 6, Rule 54 (h); 3 id., c. 93, § 2. Opinion of the Court. 337 U.S. Hence we treat the papers as a petition for certiorari, 28 U. S. C. § 2103, and grant it. 4 2. The opinion of the Supreme Court of Missouri was handed down July 12, 1948, and the motion for rehearing or for transfer to the court en banc was denied September 13, 1948. The appeal was allowed by the Missouri court on December 13, 1948. That was within three months and therefore timely prior to the revision of the Judicial Code. But 28 U. S. C. § 2101 (c), effective September 1, 1948, reduced that period to ninety days. The ninetieth day was December 12, 1948, which was a Sunday. There is a contrariety of views whether an act which by statute is required to be done within a stated period may be done a day later when the last day of the period falls on Sunday." Thus Street v. United States, 133 U. S. 299, treating Sunday as a dies non under a statute which authorized the President to transfer army officers from active duty and to fill vacancies in the active list on or before January 1, 1871, allowed the action to be taken on the following day. We think the policy of that decision is applicable to 28 U. S. C. § 2101 (c). Rule 6 (a) of the Rules of Civil Procedure provides that where the last day for performance of an act falls on a Sunday or a legal holiday, performance on the next day which is not a Sunday or legal holiday is timely. That •See Gorman v. Washington University, 316 U. S. 98. 5 Pro: Street v. United States, 133 U. S. 299; Sherwood Bros. v. District of Columbia, 72 App. D. C. 155, 113 F. 2d 162; Wilson v. Southern R. Co., 147 F. 2d 165. Contra: Johnson v. Meyers, 54 F. 417; Meyer v. Hot Springs Imp. Co., 169 F. 628; Siegelschiffer v. Penn. Mut. Life Ins. Co., 248 F. 226; Larkin Packer Co. v. Hinderliter Tool Co., 60 F. 2d 491; Walters v. Baltimore & O. R. Co., 76 F. 2d 599. 6 Rule 6 (a) provides: "In computing any period of time prescribed or allowed by these rules, by order of court, or by any applicable statute, the day of the act, event, or default after which the 888 Opinion of the Court. rule provides the method for computation of time prescribed or allowed not only by the rules or by order of court but by "any applicable statute." Since the rule had the concurrence of Congress,' and since no contrary policy is expressed in the statute governing this review, we think that the considerations of liberality and leniency which find expression in Rule 6 (a) are equally applicable to 28 U. S. C. § 2101 (c). The appeal therefore did not fail for lack of timeliness. 3. Roche v. McDonald is dispositive of the merits. Roche had a Washington judgment against McDonald. He brought suit on that judgment in Oregon. He obtained a judgment in Oregon at a time when the original judgment had by Washington law expired and could not be revived. Roche then sued in Washington on the Oregon judgment. The Court reversed the Supreme Court of Washington which had held that full faith and credit need not be given the Oregon judgment since it would have been void and of no effect if rendered in Washington. The Court held that once the court of the sister State had jurisdiction over the parties and of the subject matter its judgment was valid and could not be impeached in the State of the forum, even though it could not have been obtained there. That decision was in line with Fauntleroy v. Lum, 210 U. S. 230 and Christmas v. Russell, 5 Wall. 290. For in those cases the Court designated period of time begins to run is not to be included. The last day of the period so computed is to be included, unless it is a Sunday or a legal holiday, in which event the period runs until the end of the next day which is neither a Sunday nor a holiday. When the period of time prescribed or allowed is less than 7 days, intermediate Sundays and holidays shall be excluded in the computation. A half holiday shall be considered as other days and not as a holiday." "See Act of June 19, 1934, 48 Stat. 1064, 28 U. S. C. § 723c, now § 2072; Rule 86, Rules of Civil Procedure; Sibbach v. Wilson & Co., 312 U. S. 1. Opinion of the Court. 337 U.S. had held that the State of the forum could not defeat the foreign judgment because it was obtained by a procedure hostile to or inconsistent with that of the forum or because it was based on a cause of action which the forum itself would not have recognized. Any other result would defeat the aim of the Full Faith and Credit Clause and the statute enacted pursuant to it. It is when a clash of policies between two states emerges that the need of the Clause is the greatest. It and the statute which implements it are indeed designed to resolve such controversies. Morris v. Jones, supra. There is no room for an exception, as Roche v. McDonald makes plain, where the clash of policies relates to revived judgments rather than to the nature of the underlying claim as in Fauntleroy v. Lum, supra. It is the judgment that must be given full faith and credit. In neither case can its integrity be impaired, save for attacks on the jurisdiction of the court that rendered it. Cases of statute of limitations against a cause of action on a judgment (M'Elmoyle v. Cohen, 13 Pet. 312) in 8 Article IV, § 1 of the Constitution provides: "Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records .and Proceedings shall be proved, and the Effect thereof." The Act of Congress enacted pursuant to the Clause (28 U. S. C. § 1738), in part reads as follows: "The records and judicial proceedings of any court of any such State, Territorv or Possession, or copies thereof, shall be proved or admitted in other courts within the United States and its Territories and Possessions by the attestation of the clerk and seal of the court annexed, if a seal exists, together with a certificate of a judge of the court that the said attestation is in proper form. "Such Acts, records and judicial proceedings or copies thereof, so authenticated, shall have the same full faith and credit in every court within the United States and its Territories and Possessions as they have by law or usage in the courts of such State, Territory or Possession from which they are taken." 888 38 Opinion of the Court. volve different considerations as Christmas v. Russell, supra, p. 300, long ago pointed out. They do not undermine the integrity of the judgment on which suit is brought. In this case it is the 1945 Colorado judgment that claims full faith and credit in Missouri. No Missouri statute of limitations is tendered to cut off a cause of action based on judgments of that vintage. It is argued, however, that under Colorado law the 1945 Colorado judgment is not a new judgment and that the revivor did no more than extend the statutory period in which to enforce the old judgment. It is said that those were the assumptions on which the Missouri court proceeded. But we would have to add to and subtract from its opinion to give it that meaning. For when it placed revived judgments on the same basis as original judgments, it did so because of Missouri not Colorado law.10 This is not a situation where Colorado law also makes that conclusion plain. The Colorado authorities which There is no concession that under Colorado law revival does not make a new judgment. Petitioner merely argues that the requirements of due process are less exacting in case of a revived, as distinguished from an original, judgment. 10 The Missouri court stated, 358 Mo. p. 70, 213 S. W. 2d p. 419: "Definitely, it is the law of this state that a foreign judgment, absent revival, or a payment thereon as provided in Sec. 1038, is barred in 10 years from the date of its original rendition regardless of what the limitation period may be under the law of the state where the judgment was rendered. Northwestern Brewers Supply Co. v. Vorhees [356 Mo. 699, 203 S. W. 2d 422]. And the only reasonable conclusion to draw is that a revived judgment, domestic or foreign, absent a payment as provided in Sec. 1038, is barred under said section unless the revival was within 10 years from the date of original rendition or, if such is the case, within 10 years from the last revival. In other words, a foreign judgment, original or revived, has the same standing in Missouri, no better, no worse, than a domestic judgment. This does not run counter to the full faith and credit |
