A charge filed by or on behalf of a person claiming to be aggrieved may be withdrawn only by the person claiming to be aggrieved and only with the consent of the Commission. The Commission hereby delegates authority to District Directors, Field Directors, Area Directors, Local Directors, the Director of the Office of Field Programs and the Director of Field Management Programs, or their designees, to grant consent to a request to withdraw a charge, other than a Commissioner charge, where the withdrawal of the charge will not defeat the purposes of title VII, the ADA, GINA, or the PWFA.
