Based on title 28, U.S.C., 1940 ed., §48 (Mar. 3, 1911, ch. 231, §211,
Word "actions" was substituted for "cases and proceedings", in view of Rule 2 of the Federal Rules of Civil Procedure.
A provision authorizing intervention by the United States was omitted. The United States, under the provisions of this section, is a necessary and indispensable original party, and hence intervention is unnecessary. (See Lambert Run Coal Co. v. Baltimore & O. R. Co., 1922, 42 S.Ct. 349, 258 U.S. 377, 66 L.Ed. 671.)
