Neither a charge, nor information obtained during the investigation of a charge of employment discrimination under title VII, the ADA, GINA, or the PWFA, nor information obtained from records required to be kept or reports required to be filed pursuant to title VII, the ADA, GINA, or the PWFA, shall be made matters of public information by the Commission prior to the institution of any proceeding under title VII, the ADA, GINA, or the PWFA involving such charge or information. This provision does not apply to such earlier disclosures to charging parties, or their attorneys, respondents or their attorneys, or witnesses where disclosure is deemed necessary for securing appropriate relief. This provision also does not apply to such earlier disclosures to representatives of interested Federal, State, and local authorities as may be appropriate or necessary to the carrying out of the Commission's function under title VII, the ADA, GINA, or the PWFA, nor to the publication of data derived from such information in a form which does not reveal the identity of charging parties, respondents, or persons supplying the information.
