In the area of employment law, Syracuse University's Peter Blanck, currently Executive of the Burton Blatt Institute, has offered detailed advice on the implementation of central concepts of the employment-rehabilitation laws. While the Americans with Disabilities Act (ADA) of 1990 is the current base law, the Rehabilitation Act of 1973, amended in 1978 is also cited in these legal cases, including accommodations for individuals with intellectual and developmental disabilities. Hearings at the local levels often do not recognize experts in practice, and thus legal cases repeatedly must be appealed through the federal systems.
