Answer:
The Americans with Disabilities Act (ADA) is a law enacted by the United States Congress in 1990. Its long title is "Law to establish a clear and complete prohibition on discrimination based on disability." It was signed on July 26, 1990, by President George H. W. Bush, and then amended with changes and put into effect on January 1, 2009.
ADA is a broad civil rights law that prohibits, in certain circumstances, discrimination based on disability. Disability is defined by ADA as "a physical or mental impairment that substantially limits a major life activity." The determination of whether any condition is considered a disability is made on a case-by-case basis. Certain specific conditions are excluded as disabilities, such as substance abuse and visual impairment that can be corrected with prescription lenses.
On September 25, 2008, President George W. Bush signed the Americans with Disabilities Amendment Act of 2008. This was intended to give greater protection to disabled workers and "roll back the clock" in the judicial rulings that Congress considered too restrictive.
