Olmstead v. L.C. (1999)
The Supreme Court ruled that unjustified segregation of people with disabilities in institutions constitutes discrimination under the ADA. The decision required states to provide community-based services when appropriate and when treatment professionals agree.
States began shifting disabled people out of institutions and into community settings, with federal enforcement guidance following shortly after.
Olmstead became the legal foundation of the integration mandate for a quarter century, cited in nearly every major disability integration ruling.
The DOJ's June 2026 memo explicitly says its new position is 'out of step with the common understanding' of Olmstead, and the department is now challenging what that decision established.
