There have been some notable cases regarding the ADA. For example, two major hotel room marketers ( and with their business presence on the Internet were sued because its customers with disabilities could not reserve hotel rooms, through their websites without substantial extra efforts that persons without disabilities were not required to perform.[58] These represent a major potential expansion of the ADA in that this, and other similar suits (known as "bricks vs. clicks"), seeks to expand the ADA's authority to cyberspace, where entities may not have actual physical facilities that are required to comply.
The debate over the Americans with Disabilities Act led some religious groups to take opposite positions.[32] The Association of Christian Schools International, opposed the ADA in its original form.[33] primarily because the ADA labeled religious institutions "public accommodations", and thus would have required churches to make costly structural changes to ensure access for all.[34] The cost argument advanced by ACSI and others prevailed in keeping religious institutions from being labeled as "public accommodations".[24]
Websites must also be completely in conformance, and cannot achieve conformance if part of a website is excluded.  Further, all the information presented by, and the functionality of, web content technologies (such as HTML, CSS, and JavaScript) must be supported by accessibility web content technologies.  For more information on the five requirements for WCAG 2.0 conformance, see W3C’s WCAG’s Success Criteria, which are designed to allow online content to be tested to determine whether it satisfies the requisite criteria for a conformance level.  Testing should involve a combination of automated testing and human evaluation.
