There is uncertainty as to our power to act in the premises; but wo are clear that the state court of first instance or on appeal has full authority to settle the issue as to the validity of the service of process upon defendant Chaplin. See N. Y.Civil Practice Act, § 237-a(4); 17th Ann.Rep.N.Y. Judicial Council 62, 63 (1951). That tribunal, we believe, is now the appropriate one for all adjudication in the premises.

The petition is denied.
