In 2003, the Department of Homeland Security (DHS) published an interim final rule that established DHS procedures for the enforcement of section 504 of the Rehabilitation Act of 1973, as amended, which prohibits discrimination on the basis of handicap, as it applies to programs or activities conducted by the Department. The rule establishes standards for what constitutes discrimination on the basis of mental or physical handicap, provides a definition for individuals with handicaps and qualified individuals with handicaps, and establishes a complaint mechanism for resolving allegations of discrimination. The Department will issue a notice of proposed rulemaking proposing to revise and update the interim final rule to reflect statutory changes and the current structure of the Department.
