Where it stands
Decided

Decided 9-0 · June 27, 2019 · Opinion by Chief Justice Roberts

What it’s about
Commerce Secretary Wilbur Ross sought to add a citizenship question to the 2020 census, while New York and other states, cities, and counties argued that it could lower response rates and cause an undercount.
Who it affects
The Court rejected the idea that the Constitution itself forbids asking about citizenship and confirmed that the Secretary’s choice could be challenged under the APA. Sending the case back left further proceedings for the lower court and the parties.

What it's about

The Supreme Court ruled that the Constitution permits asking about citizenship and that Ross’s decision could be reviewed under the Administrative Procedure Act, but it left some lower-court rulings in place, overturned others, and sent the case back for another look (remanded) because his stated reason did not match the evidence.

The case tested Congress’s broad power over the census and how courts review decisions by federal agencies.

Question presented

1. WHETHER THE SECRETARY OF COMMERCE’S DECISION TO ADD A CITIZENSHIP QUESTION TO THE DECENNIAL CENSUS VIOLATED THE ENUMERATION CLAUSE OF THE U.S. CONSTITUTION, ART. I, §2, CL. 3. 2. Whether the district court erred in enjoining the Secretary of Commerce from reinstating a question about citizenship to the 2020 decennial census on the ground that the Secretary's decision violated the Administrative Procedure Act (APA), 5 U.S.C. 701 et seq. 3. Whether, in an action seeking to set aside agency action under the APA, a district court may order discovery outside the administrative record to probe the mental processes of the agency decisionmaker-including by compelling the testimony of high-ranking Executive Branch officials-without a strong showing that the decisionmaker disbelieved the objective reasons in the administrative record, irreversibly prejudged the issue, or acted on a legally forbidden basis.

What the Court decided

Holding

1. At least some respondents have Article III standing. For a legal dispute to qualify as a genuine case or controversy, at least one plaintiff must “present an injury that is concrete, particularized, and actual or imminent; fairly traceable to the defendant’s challenged behavior; and likely to be redressed by a favorable ruling.” Davis v. Cite as: 588 U. S. ____ (2019) 3 Syllabus Federal Election Comm’n , 554 U. S. 724, 733. 2. The Enumeration Clause permits Congress, and by extension the Secretary, to inquire about citizenship on the census questionnaire. That conclusion follows from Congress’s broad authority over the census, as informed by long and consistent historical practice that “has been open, widespread, and unchallenged since the early days of the Republic.” NLRB v. Noel Canning , 573 U. S. 513, 572 (Scalia, J., concurring in judgment). 3. The Secretary’s decision is reviewable under the Administrative Procedure Act. The APA instructs reviewing courts to set aside agency action that is “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law,” 5 U. S. C. §706(2)(A), but it makes review unavailable “to the extent that” the agency action is “committed to agency discretion by law,” §701(a)(2). The Census Act confers broad authority on the Secretary, but it does not leave his discretion unbounded. 4. The Secretary’s decision was supported by the evidence before him. He examined the Bureau’s analysis of various ways to collect improved citizenship data and explained why he thought the best course was to both reinstate a citizenship question and use citizen- ship data from administrative records to fill in the gaps. 351 F. Supp. 3d 502, affirmed in part, reversed in part, and remanded.

From the opinions

“For the first time ever, the Court invalidates an agency action solely because it questions the sincerity of the agency’s otherwise adequate rationale.”

— Justice Thomas(dissent)

What's next

The lower court next handles the case the Supreme Court sent back to it (remanded), applying the Court’s rulings on the Constitution and APA. The Commerce Department, New York, and the other challengers continue the dispute there.
