Horace Gray, Virginia v. Paul — Opinion of the Court
“ We do not know, therefore, whether the commonwealth of Pennsylvania intends to prosecute the defendants for the alleged offense, or whether the grand jury will find a bill, without which the prosecution cannot be said to be 'commenced in the state court.' The act contemplates the removal of a prosecution 'pending,' that a 'trial' may be had in the circuit court. If the attorney of the United States were required to send a bill of indictment before a grand jury of the United States court for a breach of the peace of the state, it would present a truly anomalous proceeding. ”
