In most cases of discrimination on the basis of disability in a postsecondary institution, and certainly in web accessibility cases, Section 504 of the Rehabilitation Act of 1973 (§504) and the Americans with Disabilities Act Amendments Act of 2008 (ADAAA) will be appropriate avenues for bringing a complaint. The Office for Civil Rights (OCR) has responsibility for enforcing both these federal laws in public educational settings and would hear a complaint regarding inaccessible websites.
