The ADAAA explicitly overturns the controversial Supreme Court decisions in
Sutton The ADAAA retains the ADA's definition of disability as a physical or mental impairment that substantially limits one or more life activities; a record of such impairment; or being regarded as having such impairment. However, it clarifies and expands the definition's meaning and application in the following ways: First, the ADAAA deletes two findings in the ADA that led the Supreme Court to restrict the meaning and application of the definition of disability. These findings were that "some 43,000,000 Americans have one or more physical or mental disabilities" and that "individuals with disabilities are a discrete and insular minority." The Court had treated these findings as limiting how other provisions of the ADA should be construed. Second, the law provides that the definition of disability "shall be construed in favor of broad coverage of individuals under this Act, to the maximum extent permitted by the terms of this Act." It retains the terms "substantially limits" and "major life activities" from the original ADA definition of "disability," but makes clear that Congress intended the terms to impose less- demanding standards than those enunciated by the Supreme Court in the Toyota case. It also states that the EEOC's regulatory definition of "substantially limits" was overly strict. Third, the law prohibits consideration of mitigating measures such as medication, assistive technology, accommodations, or modifications when determining whether an impairment substantially limits a major life activity. The related text of the ADAAA explicitly rejects the Supreme Court's holdings in
Sutton and its companion cases that mitigating measures must be considered in determining whether an impairment constitutes a disability under the law. The ADAAA also provides that impairments that are episodic or in remission must be assessed according to their active state. Fourth, the law provides additional direction on the "major life activities" that must be substantially limited for an impairment to be a disability: the Act lists specific examples of
major life activities, rather than leaving that phrase open to interpretation, as the ADA of 1990 did. The non-exhaustive list of major life activities in § 4(4)(a) of the amended ADA includes caring for oneself, performing manual tasks, seeing, hearing, eating, sleeping, walking, standing, lifting, bending, speaking, breathing, learning, reading, concentrating, thinking, communicating and working. The ADAAA also lists
major bodily functions, including, but not limited to, functions of the immune system; normal cell growth; and digestive, bowel, bladder, neurological, brain, respiratory, circulatory, endocrine, and reproductive functions. ==Legislative history==
