(a) Any member of the Commission may file a charge with the Commission. Such charge shall be in writing and signed and shall be verified.

(b) A Commissioner who files a charge under paragraph (a) of this section may withdraw the charge with the consent of the Commission. The Commission may withdraw any charge filed under paragraph (a) of this section by a Commissioner who is no longer holding office when it determines that the purposes of title VII, the ADA, or GINA are no longer served by processing the charge. Commissioner charges may not be withdrawn pursuant to this section after a determination as to reasonable cause has been made. This paragraph does not apply to a charge filed by a Commissioner which is on behalf of a person claiming to be aggrieved within the meaning of § 1601.7 unless such person submits a written request for withdrawal to the Commission.
