Except as provided in clause (iii), the attorney general of a State shall notify the Commission in writing that the attorney general intends to bring a civil action under paragraph (1) not later than 10 days before initiating the civil action.
The notification required by clause (i) with respect to a civil action shall include a copy of the complaint to be filed to initiate the civil action.
Nothing in this subsection may be construed to prevent the attorney general of a State from exercising the powers conferred on the attorney general by the laws of the State to conduct investigations, to administer oaths or affirmations, or to compel the attendance of witnesses or the production of documentary or other evidence.
If the Commission institutes a civil action or an administrative action with respect to a violation of subsection (a), the attorney general of a State may not, during the pendency of such action, bring a civil action under paragraph (1) against any defendant named in the complaint of the Commission for the violation with respect to which the Commission instituted such action.
In addition to civil actions brought by attorneys general under paragraph (1), any other consumer protection officer of a State who is authorized by the State to do so may bring a civil action under paragraph (1), subject to the same requirements and limitations that apply under this subsection to civil actions brought by attorneys general.
