Writing for the majority, Justice Ruth Bader Ginsburg upheld the lower courts' finding that "unjustified institutional isolation of persons with disabilities is a form of discrimination" that was forbidden by the ADA. She noted that institutional placement both "perpetuates unwarranted assumptions that persons so isolated are incapable or unworthy of participating in community life," and "severely diminishes the everyday life activities of individuals, including family relations, social contacts, work options, economic independence, educational advancement, and cultural enrichment." Persons with mental disabilities are discriminated against because they must forgo community life to receive the medical treatment they need, whereas persons without mental disabilities can receive medical services without sacrificing their ties to the community.
