In all courts of the United States the parties may plead and conduct their own cases personally or by counsel as, by the rules of such courts, respectively, are permitted to manage and conduct causes therein. (June 25, 1948, ch. 646, 62 Stat. 944 ; May 24, 1949, ch. 139, § 91, 63 Stat. 103 .) Historical Revision Notes 1948 Act Based on title 28, U.S.C., 1940 ed., § 394 (Mar. 3, 1911, ch. 231, § 272, 36 Stat. 1164 ). Words “as, by the rules of the said courts respectively, are permitted to manage and conduct causes therein,” after “counsel,” were omitted as surplusage. The revised section and section 2071 of this title effect no change in the procedure of the Tax Court before which certain accountants may be admitted as counsel for litigants under Rule 2 of the Tax Court. Changes were made in phraseology. 1949 Act This section restores in section 1654 of title 28 , U.S.C., language of the original law. Editorial Notes Amendments 1949—Act May 24, 1949 , inserted “as, by the rules of such courts, respectively, are permitted to manage and conduct causes therein”.
