Congress passed the Americans with Disabilities Act (ADA) in 1991. It is a complex law, with profound impacts on many areas of society, and it is poorly drafted in several critical areas. As such, the ADA generated substantial litigation from within a few months of its passage. It has only been in the last 14 months that the United States Supreme Court has ruled on cases dealing with the ADA. These rulings have clarified some aspects of the ADA, while raising new controversies with other sections. This review attempts to explain these Supreme Court cases within the context of the overall construction of the ADA. Some of this discussion is based on previous articles in LMP and on Richards and Rathbun, Medical Care Law, Aspen Publishers (1999).
