(a) Procedures for handling dual-filed complaints or charges. As between the EEOC and a section 504 agency, except as provided in paragraph (e) of this section, a complaint or charge of employment discrimination that is dual filed with both the EEOC and a section 504 agency shall be processed as follows:

(1) EEOC processing. The EEOC shall investigate and process the charge when the EEOC determines that it has jurisdiction over the charge under title I and the charge solely alleges employment discrimination against an individual, unless the charging party elects to have the section 504 agency process the charge and the section 504 agency receives a written request from the complainant for section 504 agency processing within twenty days of the date of the notice letter required to be sent pursuant to § 1640.6(c)(2)(ii).

(2) Section 504 agency processing. A section 504 agency shall investigate and process the complaint when the agency determines that it has jurisdiction over the complaint under section 504, and:

(i) The complaint alleges discrimination in both employment and in other practices or services of the respondent; or

(ii) The complaint alleges a pattern or practice of discrimination in employment; or

(iii) In the case of a complaint solely alleging employment discrimination against an individual, the complainant elects to have a section 504 agency process the complaint and the section 504 agency receives a written request from the complainant for section 504 agency processing within twenty days of the date of the notice letter required to be sent pursuant to § 1640.6(c)(2)(ii).

(b) Referral to the Civil Rights Division. If the EEOC determines that it does not have jurisdiction under title I, and the section 504 agency determines that it does not have jurisdiction under section 504 or title II, the complaint or charge shall be promptly referred to the Civil Rights Division. The Civil Rights Division shall determine if another Federal agency may have jurisdiction over the complaint under section 504 or title II, and, if so, shall promptly refer the complaint to a section 504 or a designated agency with jurisdiction over the complaint.

(c) Procedures for determining whether a complaint or charge has been dual filed. The EEOC and each agency with jurisdiction to investigate and process complaints of employment discrimination under section 504 shall jointly develop procedures for determining whether complaints or charges of discrimination have been dual filed with the EEOC and with one or more other agencies.

(d) Notification of deferral. The agency required to process a dual-filed complaint or charge under this section shall notify the complainant or charging party and the respondent that the complaint or charge was dual filed with one or more other agencies and that such other agencies have agreed to defer processing and will take no further action except as provided in § 1640.10 or § 1640.11, as applicable.

(e) Exceptions. When special circumstances make deferral as provided in this section inappropriate, the EEOC, and an agency with investigative authority under section 504, may jointly determine to reallocate investigative responsibilities. Special circumstances include, but are not limited to, cases in which the EEOC has already commenced its investigation at the time that the agency discovers that the complaint or charge is a dual-filed complaint or charge in which the complainant has elected section 504 processing, alleged discrimination in both employment and in other practices or services of the respondent, or alleged a pattern or practice of employment discrimination.
