((a)) ** .—** The chief judge shall expeditiously review any complaint received under section 351(a) or identified under section 351(b). In determining what action to take, the chief judge may conduct a limited inquiry for the purpose of determining—

((1)) whether appropriate corrective action has been or can be taken without the necessity for a formal investigation; and

((2)) whether the facts stated in the complaint are either plainly untrue or are incapable of being established through investigation.

((b)) ** .—** After expeditiously reviewing a complaint under subsection (a), the chief judge, by written order stating his or her reasons, may—

((1)) dismiss the complaint—

((A)) if the chief judge finds the complaint to be—

((i)) not in conformity with section 351(a);

((ii)) directly related to the merits of a decision or procedural ruling; or

((iii)) frivolous, lacking sufficient evidence to raise an inference that misconduct has occurred, or containing allegations which are incapable of being established through investigation; or

((B)) when a limited inquiry conducted under subsection (a) demonstrates that the allegations in the complaint lack any factual foundation or are conclusively refuted by objective evidence; or

((2)) conclude the proceeding if the chief judge finds that appropriate corrective action has been taken or that action on the complaint is no longer necessary because of intervening events.

((c)) ** .—** A complainant or judge aggrieved by a final order of the chief judge under this section may petition the judicial council of the circuit for review thereof. The denial of a petition for review of the chief judge’s order shall be final and conclusive and shall not be judicially reviewable on appeal or otherwise.

((d)) ** .—** Each judicial council may, pursuant to rules prescribed under section 358, refer a petition for review filed under subsection (c) to a panel of no fewer than 5 members of the council, at least 2 of whom shall be district judges.
