Search 15 U.S.C. § 25 : US Code - Section 25: Restraining violations; procedure

The several district courts of the United States are invested
with jurisdiction to prevent and restrain violations of this Act,
and it shall be the duty of the several United States attorneys, in
their respective districts, under the direction of the Attorney
General, to institute proceedings in equity to prevent and restrain
such violations. Such proceedings may be by way of petition setting
forth the case and praying that such violation shall be enjoined or
otherwise prohibited. When the parties complained of shall have
been duly notified of such petition, the court shall proceed, as
soon as may be, to the hearing and determination of the case; and
pending such petition, and before final decree, the court may at
any time make such temporary restraining order or prohibition as
shall be deemed just in the premises. Whenever it shall appear to
the court before which any such proceeding may be pending that the
ends of justice require that other parties should be brought before
the court, the court may cause them to be summoned whether they
reside in the district in which the court is held or not, and
subpoenas to that end may be served in any district by the marshal
thereof.
