Nancy Lee Jones, The Americans with Disabilities Act: Application to the Internet (CRS Report R40462) (Oct. 13, 2010) (full-text).
The Americans with Disabilities Act (ADA) provides broad, nondiscrimination protection in employment, public services, public accommodations, and services operated by private entities, transportation, and telecommunications for individuals with disabilities. As stated in the Act, its purpose is "to provide a clear and comprehensive national mandate for the elimination of discrimination against individuals with disabilities."
However, the ADA, enacted on July 26, 1990, prior to widespread use of the Internet, does not specifically cover the Internet, and the issue of coverage has not been definitively resolved. The U.S. Supreme Court has not addressed this issue, although there are some lower court decisions. The cases that directly discuss the ADA's application to the Internet vary in their conclusions about coverage.
