Any interested person (including any individual or nonprofit,
business, or other entity) may bring an action in any United States district court for the
district in which the defendant is found or transacts business to enforce a consumer
product safety rule or an order under section 2064 of this title, and to
obtain appropriate injunctive relief. Not less than thirty days prior to the commencement
of such action, such interested persons shall give notice by registered mail to the
Commission, to the Attorney General, and to the person against whom such action is
directed. Such notice shall state the nature of the alleged violation of any such standard
or order, the relief to be requested, and the court in which the action will be brought.
No separate suit shall be brought under this section if at the time the suit is brought
the same alleged violation is the subject of a pending civil or criminal action by the
United States under this chapter. In any action under this section the court may in the
interest of justice award the costs of suit, including reasonable attorneys' fees
(determined in accordance with section 2060(f) of this title) and
reasonable expert witnesses' fees.
