Most folks don't pay much attention to administrative law.  It is not an area of law taught at any level of school except law; it is hardly mentioned in 7th grade civics, for example, too busy with the tripartite form of republican democracy.  If you take American history as an undergraduate it shows up most prominently in a discussion of the New Deal and the alphabet soup of federal agencies that emerged with Roosevelt's social policy from the first 100 days through to the establishment of the Social Security Administration and National Labor Relations Board in the second administration.  Its history began much earlier, however, with the Interstate Commerce Commission of 1887 formed to regulate railroads.  In 1914, Congress passed the Federal Trade Commission Act, which was the statutory basis of the Federal Trade Commission.    

Dan Goldstein, attorney for National Federation of the Blind, has recently published the clearest articulation to date of the relationship between disability law and web accessibility.  In short, while the Americans Disability Act, promulgated in 1990, did not explicitly speak to cyberspace, it nonetheless is the legal foundation upon which accommodations to it are required of those entities that fall under its scope, including higher education.  This point is an important one to make.  For some years, institutional attorneys and disability advocates have gotten tangled in discussions about whether section 508 of the Rehabilitation Act, which outlines a baseline of technical standards for web accessibility and is required for all federal agencies, is required of colleges and universities.
