Rule 37. Interest on Judgment
(a) When the Court Affirms. Unless the law provides otherwise, if a money judgment in a civil case is affirmed, whatever interest is allowed by law is payable from the date when the district court's judgment was entered.
(b) When the Court Reverses. If the court modifies or reverses a judgment with a direction that a money judgment be entered in the district court, the mandate must contain instructions about the allowance of interest.
(As amended Apr. 24, 1998, eff. Dec. 1, 1998.)
Notes of Advisory Committee on Rules—1967
The first sentence makes it clear that if a money judgment is affirmed in the court of appeals, the interest which attaches to money judgments by force of law (see 28 U.S.C. §1961 and §2411) upon their initial entry is payable as if no appeal had been taken, whether or not the mandate makes mention of interest. There has been some confusion on this point. See Blair v. Durham, 139 F.2d 260 (6th Cir., 1943) and cases cited therein.
In reversing or modifying the judgment of the district court, the court of appeals may direct the entry of a money judgment, as, for example, when the court of appeals reverses a judgment notwithstanding the verdict and directs entry of judgment on the verdict. In such a case the question may arise as to whether interest is to run from the date of entry of the judgment directed by the court of appeals or from the date on which the judgment would have been entered in the district court except for the erroneous ruling corrected on appeal. In Briggs v. Pennsylvania R. Co., 334 U.S. 304, 68 S.Ct. 1039, 92 L.Ed. 1403 (1948), the Court held that where the mandate of the court of appeals directed entry of judgment upon a verdict but made no mention of interest from the date of the verdict to the date of the entry of the judgment directed by the mandate, the district court was powerless to add such interest. The second sentence of the proposed rule is a reminder to the court, the clerk and counsel of the Briggs rule. Since the rule directs that the matter of interest be disposed of by the mandate, in cases where interest is simply overlooked, a party who conceives himself entitled to interest from a date other than the date of entry of judgment in accordance with the mandate should be entitled to seek recall of the mandate for determination of the question.
Committee Notes on Rules—1998 Amendment
The language and organization of the rule are amended to make the rule more easily understood. In addition to changes made to improve the understanding, the Advisory Committee has changed language to make style and terminology consistent throughout the appellate rules. These changes are intended to be stylistic only.
