United States v. Mayer — Opinion of the Court
“ Under § 239 of the Judicial Code [36 Stat. at L. 1157, chap. 231, U.S.C.omp. Stat. Supp. 1911, p. 228] , questions may be certified by the circuit court of appeals 'in any case within its appellate jurisdiction, as defined in section one hundred and twenty-eight;' and § 128 provides that the circuit courts of appeals 'shall exercise appellate jurisdiction to review by appeal or writ of error final decisions in the district courts,' etc. The argument is that an application to a circuit court of appeals for a writ of prohibition is an original proceeding. ”
