Americans with Disabilities Act

The Americans with Disabilities Act (ADA), Public Law 101-336, was signed by President George H. W. Bush on July 26, 1990, after passing the Senate 91-6 and the House 377-28. It is the most comprehensive disability-rights legislation in U.S. history, building on Section 504 of the Rehabilitation Act of 1973, which had barred disability discrimination by federally funded entities. The ADA extends that principle to private employers, state and local governments, and privately owned public accommodations. It defines "disability" as a physical or mental impairment that substantially limits one or more major life activities, a record of such impairment, or being regarded as having one—a definition deliberately broadened by the ADA Amendments Act of 2008 (ADAAA) to reverse restrictive Supreme Court readings in Sutton v. United Air Lines (1999) and Toyota Motor Mfg. v. Williams (2002).

The statute is organized into five titles. Title I bars employment discrimination by employers with 15 or more workers and requires "reasonable accommodation" unless it imposes "undue hardship"; it is enforced by the Equal Employment Opportunity Commission (EEOC). Title II covers public services, including transit, and mandates program accessibility by state and local governments. Title III governs public accommodations—restaurants, hotels, theaters, retail—requiring removal of architectural barriers where "readily achievable" and compliance with the ADA Accessibility Guidelines. Title IV, administered through the FCC, requires telecommunications relay services for the hearing- and speech-impaired. Title V contains miscellaneous provisions, including anti-retaliation protections. The Department of Justice promulgates the implementing regulations and litigates Title II and III cases.

Landmark judicial interpretation includes Olmstead v. L.C. (1999), in which the Supreme Court held that the unjustified institutional isolation of persons with disabilities constitutes discrimination under Title II, establishing the "integration mandate" and accelerating community-based care. PGA Tour, Inc. v. Martin (2001) applied Title III to require a golf tour to permit a disabled player to use a cart. Tennessee v. Lane (2004) upheld Congress's abrogation of state sovereign immunity under Title II for courthouse access, while Board of Trustees of the University of Alabama v. Garrett (2001) had limited such abrogation for Title I damages claims. As of 2026 the ADAAA's expanded definition remains controlling, and web-accessibility litigation under Title III continues to grow in the absence of definitive DOJ digital-access standards.

For the FSOT and US-history sections of competitive exams, the ADA exemplifies the post-civil-rights expansion of anti-discrimination law and the use of the Commerce Clause and Section 5 of the Fourteenth Amendment as legislative bases. Candidates should be able to date the 1990 enactment and the 2008 amendment, name George H. W. Bush as signatory, distinguish the five titles, and connect Olmstead to deinstitutionalization. Typical exam angles contrast the ADA with the Rehabilitation Act of 1973, ask which agency enforces employment claims (EEOC), or test the "reasonable accommodation"/"undue hardship" balancing standard.
