Department of Commerce v. New York
The Supreme Court ruled that the Constitution and federal census law allow the government to ask about citizenship on the census, and that the Secretary of Commerce's basic policy choice to add the question was a reasonable exercise of his discretion.
But the Court also found that the sole reason the Secretary actually gave — helping enforce the Voting Rights Act — did not match what the evidence showed really drove the decision, so it sent the question back to the agency for a genuine explanation before it could be added to the 2020 census.
“the evidence tells a story that does not match the explanation the Secretary gave for his decision.”
The Court's core finding that the Secretary's stated rationale did not reflect his real reasons.
How it got here: A federal trial court in New York held a bench trial, ruled for the challengers, and blocked the question; the government sought direct Supreme Court review before any appeals court ruling.
The Case in Depth
What happened
The Secretary of Commerce announced in 2018 that the 2020 census would ask everyone about citizenship, saying the Justice Department needed the data to enforce the Voting Rights Act. States, cities, and immigrant-rights groups sued, arguing the question would scare noncitizen households into not responding, undercounting their communities and costing some states federal money and congressional seats.
The question before the Court
Could the Secretary of Commerce add a citizenship question to the 2020 census based on the reason he gave — helping enforce the Voting Rights Act?
The Court's answer
No — not on the record here. The Court agreed that the Constitution and the Census Act allow the Secretary to ask about citizenship, and it found nothing legally wrong with his underlying policy choice to combine a citizenship question with administrative records. But the Court also concluded that the one reason the Secretary actually gave — helping the Justice Department enforce the Voting Rights Act — did not match what the evidence showed had really driven the decision.
Because agencies must give genuine, not contrived, explanations for their actions, the Court sent the citizenship question back to the Commerce Department so the Secretary could provide a truthful account of his reasons, or reconsider the decision, before it could be added to the 2020 census.

Why it matters
The ruling determines whether census forms mailed to every U.S. household would ask about citizenship, a change advocacy groups warned would depress responses from immigrant communities and skew the population counts used to distribute congressional seats and federal funding. It also gives courts a new tool — reviewing agencies for contrived justifications — that reshapes how other agency decisions can be challenged.
What changes now
The case returns to the Commerce Department, which must either offer a genuine explanation for reinstating the citizenship question or reconsider the decision altogether. Because census forms must be finalized on a tight printing schedule, the practical effect of the remand depends heavily on timing. This is a final merits ruling on the legal questions presented, not an emergency or temporary order, though further proceedings on remand remain possible.
What this does not decide
The Court did not hold that a citizenship question is unlawful or unconstitutional, and did not decide the constitutionality of any other census question. It held only that the Secretary's specific, sole stated justification for this citizenship question was contrived and did not match the record — not that the underlying policy choice was invalid.
Concurrences and dissents
Dissent in part — Justice Thomas
“The Court, I fear, will come to regret inventing the principles it uses to achieve today's result.”Thomas's warning that the pretext ruling departs dangerously from deferential agency review.
Justice Thomas agreed the decision was lawful and reasonably explained but dissented from the Court's pretext holding, calling it an unprecedented and dangerous departure from deferential review. He argued the evidence showed at most that the Secretary had additional unstated reasons, which is not enough to invalidate an agency action, and warned the ruling opens the door to endless pretext litigation against future agency decisions.
Dissent in part — Justice Breyer
Justice Breyer agreed the rationale was pretextual and that remand was proper, but argued the majority did not go far enough: he would have held the decision arbitrary and capricious on the merits regardless of pretext, because the Secretary ignored strong evidence that the citizenship question would produce less accurate data and cause a significant undercount.
Dissent in part — Justice Alito
Justice Alito argued the Secretary's decision was committed entirely to agency discretion by law and therefore not reviewable under the APA at all, given the sweeping statutory language, the lack of any historical tradition of judicial review of census content, and the disruptive consequences of allowing courts to probe executive motives.
How the Court got there
The legal reasoning, step by step
- The Court first addressed standing, the requirement that a plaintiff show a real, concrete harm. It found that an undercount of noncitizen households would predictably cost some states federal funding tied to population, which was a concrete and imminent enough injury even though it depended on other people's unlawful failure to respond to the census.
- On the constitutional question, the Court declined to apply a strict 'reasonable relationship to an accurate headcount' test, reasoning that such a test would make every census since 1790 unconstitutional given how many demographic questions have always been asked. Instead, relying on nearly two centuries of unbroken practice, the Court held the Enumeration Clause lets Congress and the Secretary collect citizenship information as part of the census.
- Turning to whether courts could review the decision at all under the Administrative Procedure Act, the Court held that the narrow exception for actions 'committed to agency discretion by law' did not apply here, because several specific provisions of the Census Act gave courts something meaningful to measure the Secretary's decision against.
- Applying the deferential arbitrary-and-capricious standard — which asks only whether the agency examined the relevant evidence and gave a rational explanation — the Court concluded the Secretary's choice to combine a citizenship question with administrative records was a reasonable policy call among uncertain options, and that courts may not second-guess that kind of value-laden tradeoff.
- Invoking a narrow exception, first recognized in a 1971 case, that allows courts to look behind an agency's official explanation on a strong showing of bad faith, the Court reviewed the full record, including material obtained through extra-record discovery, and found a 'significant mismatch' between the Secretary's stated Voting Rights Act rationale and what the evidence showed had actually driven the decision.
- Because meaningful judicial review requires an agency's stated reasons to be genuine rather than contrived, the Court held that this mismatch meant the explanation failed the reasoned-decisionmaking requirement, warranting a return of the matter to the agency rather than acceptance of the stated rationale.
