Louis Brandeis, McDonnell v. United States, 288 U.S. 420…
“ The contention is that, since the period of limitation had expired before the passage of the 1924 act, the waiver was inoperative under the express terms of paragraph (e) of section 278 of that act, which declares: "This section shall not (1) authorize the assessment of a tax or the collection thereof by distraint or by a proceeding in court if at the time of the enactment of this Act such assessment, distraint, or proceeding was barred by the period of limitation then in existence, or (2) affect any assessment made, or distraint or proceeding in court begun, before the enactment of this Act." ”
