Courts have essentially taken three positions when approached with this issue. Some courts take the position that the ADA applies to all commercial sites because the law was meant to protect disabled individuals from having a more difficult time than able-bodied individuals from doing business. That is why the website Scribd was unable to get a case summarily dismissed and ended up settling.
Further complicating the issue, the U.S. recently appeared to be on the verge of adopting more comprehensive accessibility requirements. Federal regulations slated to go into effect in January 2018 would have held federal websites to the standards of WCAG 2.0 Level AA, the set of guidelines that provide the basis for online accessibility rules for most of Europe and many other nations around the world. The current administration, however, has withdrawn this requirement as part of a general push toward deregulation, leaving the online applications of the ADA as murky as ever.
The Department has assembled an official online version of the 2010 Standards to bring together the information in one easy-to-access location. It provides the scoping and technical requirements for new construction and alterations resulting from the adoption of revised 2010 Standards in the final rules for Title II (28 CFR part 35) and Title III (28 CFR part 36).
