Where the power of any court of appeals to review a case depends upon the amount or value in controversy, such amount or value, if not otherwise satisfactorily disclosed upon the record, may be shown and ascertained by the oath of a party to the case or by other competent evidence.
28 U.S.C. § 2108
HISTORICAL AND REVISION NOTES Based on title 28, U.S.C., 1940 ed., §231 (Feb. 13, 1925, ch. 229, §9, 43 Stat. 941).Words "or in the Supreme Court" were omitted. Section 7 of the 1925 act containing such words related to review by the Supreme Court of the United States of decisions of the Supreme Court of the Philippine Islands and designated a certain jurisdictional amount. Such section 7 has now become obsolete, in view of the recognition of the independence of the Philippines, title 48 U.S.C., 1940 ed., §1240, Territories and Insular Possessions, and there is no other case wherein the power of the Supreme Court to review depends on the amount or value in controversy.
