The Department of Justice’s Office of Legal Counsel (OLC) has issued a slip opinion concluding that neither Section 504 of the Rehabilitation Act nor Title II of the Americans with Disabilities Act (ADA) requires states to treat patients with severe mental illness or disabilities in the “most integrated setting” appropriate to their needs — and that federal regulations imposing that requirement, in place in some form since 1978, exceed what Congress actually authorized. The opinion, signed by Principal Deputy Assistant Attorney General Lanora C. Pettit, was written for the White House Counsel’s Office in response to a formal request for OLC’s legal views on the so-called “integration mandate.”

OLC opinions are formal legal advice the department’s Office of Legal Counsel gives to the President and executive agencies; they bind Executive Branch practice going forward but are not court rulings and do not themselves change what a federal court would hold. This opinion answers three questions the White House Counsel’s Office posed: whether the Supreme Court’s 1999 decision in Olmstead v. L.C. ex rel. Zimring, 527 U.S. 581, already settled that the statutes impose an integration mandate; if not, whether Congress could constitutionally impose one; and whether Congress in fact did so. OLC answers the first and third questions no, and concludes that because there is no statutory mandate to interpret, it does not need to resolve the constitutional question directly — though it says the serious constitutional doubts such a mandate would raise reinforce its reading of the statutory text.

The opinion’s reading of Olmstead is narrower than how the decision is understood by most federal courts. Olmstead itself was fractured: a five-justice majority held that “unjustified institutional isolation of persons with disabilities is a form of discrimination” under Title II, but only a four-justice plurality, led by Justice Ginsburg, went on to say that community-based treatment becomes mandatory once a state’s own treatment professionals find it appropriate, the patient does not object, and it can reasonably be accommodated given the state’s resources. Because that three-factor test never commanded a majority, OLC applies the Supreme Court’s “narrowest grounds” rule from Marks v. United States to conclude Olmstead’s binding holding is limited to the bare proposition that unjustified institutionalization can be discriminatory — without settling what counts as adequate justification for treating a patient in an institution. OLC acknowledges this view cuts against how most federal circuit courts have treated Olmstead’s plurality language as binding, but says that disagreement is the kind of “contested legal question” the political branches and courts are meant to work out over time.

Turning to the statutory text, the opinion argues “discrimination” in Section 504 and Title II, understood by its ordinary meaning when each law was passed, means treating similarly situated people differently without adequate justification — not an affirmative duty to provide services in a particular setting. It points to Title III of the ADA, which explicitly requires public accommodations to operate in “the most integrated setting appropriate,” and argues Title II’s omission of that same language was intentional. Under OLC’s reading, a state does not discriminate by treating a patient with mental illness in an institution so long as it has any non-arbitrary reason for doing so — including resource and space constraints, safety concerns, or the patient’s own medical needs — and disability discrimination occurs only when disability itself, rather than the needs disability creates, is the sole basis for the treatment setting chosen.

The opinion separately walks through why reading an integration mandate into the statutes would raise serious constitutional problems under three possible sources of congressional power: Section 5 of the Fourteenth Amendment, which the opinion says would require a legislative record showing a pattern of irrational state discrimination that a universal integration mandate does not appear to have; the Interstate Commerce Clause, which the opinion argues does not reach a purely in-state choice about where to treat a patient; and the Spending Clause, under which conditions on federal funds must be stated unambiguously, which OLC says neither statute does with respect to treatment setting. Because of these doubts, OLC applies the constitutional avoidance canon to reinforce its narrower statutory reading.

The opinion’s bottom line is that the Department of Health and Human Services’ regulation at 45 C.F.R. § 84.76(b) and the Department of Justice’s regulation at 28 C.F.R. § 35.130(d) — the regulations that first created the “most integrated setting” requirement and that the Olmstead Court leaned on in reaching its own holding — exceed the authority Congress gave those agencies, since Section 504 authorizes only regulations “necessary to carry out” the antidiscrimination provision and a general integration requirement is not necessary to eliminate discrimination as OLC defines it. The opinion recommends the regulations be rescinded, along with related sub-regulatory guidance the Department of Justice has issued interpreting Olmstead broadly, on the ground that such guidance never had the force of law in the first place. The opinion also notes that DOJ’s Civil Rights Division has for two decades used the integration mandate and Olmstead to secure consent decrees and settlement agreements committing roughly a dozen states to specific deinstitutionalization benchmarks — agreements this opinion does not purport to unwind, but whose legal foundation it calls into question going forward.

The opinion is explicit about its own limits: it addresses only patients with severe mental illness or developmental disabilities of the kind at issue in Olmstead, expressly reserving how its reasoning would apply to physical disabilities, and it states it is not questioning the general constitutionality of Section 504 or Title II outside the integration-mandate context. It also acknowledges, more than once, that its interpretation departs from the near-uniform practice of federal appellate courts and from HHS and DOJ’s own consistent position since the late 1970s, framing that departure as the product of an independent legal analysis conducted under current Supreme Court methodology (including 2024’s Loper Bright Enterprises v. Raimondo, which ended judicial deference to agency interpretations of ambiguous statutes) rather than as a rejection of Olmstead itself.

This summary is provided for general informational purposes only and does not constitute legal advice. An OLC opinion states the Executive Branch’s own legal position; it does not overrule Olmstead v. L.C. or the federal appellate decisions applying it, and any change to existing regulations, consent decrees, or DOJ enforcement practice would require separate agency or judicial action.
