opinion: Per Curiam:
  The motion of the Government to remand the case to the District Court is denied.
  The judgment is vacated and the case is remanded to the District Court with instructions to grant the defendants a new trial.
  Mr. Justice Frankfurter, Mr. Justice Burton, and Mr. Justice Harlan dissent, believing the Government’s motion to remand should be granted, and reserve the right to file an opinion.
