Search 18 U.S.C. § 2521 : US Code - Section 2521: Injunction against illegal interception

Whenever it shall appear that any person is engaged or is about
to engage in any act which constitutes or will constitute a felony
violation of this chapter, the Attorney General may initiate a
civil action in a district court of the United States to enjoin
such violation. The court shall proceed as soon as practicable to
the hearing and determination of such an action, and may, at any
time before final determination, enter such a restraining order or
prohibition, or take such other action, as is warranted to prevent
a continuing and substantial injury to the United States or to any
person or class of persons for whose protection the action is
brought. A proceeding under this section is governed by the Federal
Rules of Civil Procedure, except that, if an indictment has been
returned against the respondent, discovery is governed by the
Federal Rules of Criminal Procedure.
