In proceedings taken under the so-called Walsh Act the petitioner, Blackmer, a United States citizen residing in France, was found guilty of contempt for failure to respond to subpoenas issued out of a federal court and served on him in France by a United States consul requiring him to appear as a witness in that court. See 30 MICH. L. REV. 137 (1931) for a more detailed statement of the facts. By a unanimous decision (Mr. Justice Roberts not participating) the United States Supreme Court recently held that the contempt decree be affirmed, thus sustaining the constitutionality of the Walsh Act. Blackmer v. United States (U.S. 1931) Adv. Op. Nos. 200 and 201.
