On June 22, 2011, the 12th anniversary of the Supreme Court's Olmstead decision, the U.S. Department of Justice (DOJ) released a technical assistance document clarifying aspects of the landmark 1999 decision. In the Olmstead case the Court ruled that under the Americans With Disabilities Act (ADA) the unjustified institutional isolation of people with disabilities is a form of unlawful discrimination. The decision affirmed the rights of people with mental illnesses and other disabilities to live in their communities. The DOJ's new technical assistance document offers guidance on such topics as the obligations of public entities to provide community-based services. To commemorate the anniversary, the DOJ also launched a new section of its ADA Web site that gathers resources related to Olmstead (www.ada.gov/olmstead), such as recent briefs filed by the department to enforce the provisions of the decision.
