Issue. Must there be due process for the exercise of judicial jurisdiction in personam?
Held. (Hughes, C.J). Yes. There must be due process for the exercise of judicial jurisdiction in personam. The court may adjudge the witness guity of contempt if the witness fails to comply with the court order. Congress acted pursuant to its authority in enacting the statute and it could prescribe a penalty to enforce it. Affirmed.
Discussion. The statute was not found to be unconstitutional by the Court. Blackmer (D) alleged that there was inadequate notice, but since he still retained his U.S. citizenship, he was still subject to the U.S. authorities.
