BP p.l.c. v. Mayor and City Council of Baltimore
The Supreme Court ruled that federal appeals courts may review every reason a district court gave for sending a case back to state court, as long as the company that moved the case to federal court cited the federal officer removal law as one of its grounds.
The decision resolves a long-running split among the federal appeals courts over how broad their authority is when they review orders returning cases to state court, and it gives defendants who invoke the federal officer removal law a more complete second look on appeal.
How it got here: The district court rejected all grounds for removal and sent the case back to state court; the Fourth Circuit reviewed only the federal officer ground and affirmed; the energy companies asked the Supreme Court to hear the case to resolve a circuit split.
The Case in Depth
What happened
Baltimore's mayor and city council sued major oil and gas companies in Maryland state court, claiming the companies hid the environmental harms caused by their fossil fuel products. The companies moved the case to federal court, citing five different legal bases, including a law that guarantees federal court access for defendants acting on the federal government's behalf. The district court rejected every basis and sent the case back to state court.
The question before the Court
When energy companies sued in state court cite the federal officer removal law as one of several reasons to move a case to federal court, can an appeals court review all of the removal grounds — not just the federal officer ground — if a judge sends the case back to state court?
The Court's answer
Yes — when a defendant invokes the federal officer removal statute (§1442) or the civil rights removal statute (§1443) as one of its grounds to move a case to federal court, and the trial court sends the case back to state court, a federal appeals court may examine every ground the trial court rejected — not only the §1442 or §1443 argument.
The Court's reasoning centered on the word "order" in the relevant statute. A remand order is a single court command, and that command necessarily addressed all the grounds for removal because the trial court was obligated to consider each one before it could legally return the case to state court. Granting appellate review of the whole "order" therefore means review of every issue within it. The statute contains no language limiting review to cases removed "solely under" §1442 or §1443, and Congress knows how to add that kind of restriction when it wants to.

Why it matters
Companies and other defendants who remove cases from state to federal court by invoking the federal officer removal law will now be able to get a federal appeals court to review every ground for removal the trial court rejected — not just the federal officer argument. This could delay cases like Baltimore's climate lawsuit, which must now return to the Fourth Circuit for a fuller review before the merits can be heard anywhere.
What changes now
The case returns to the Fourth Circuit, which must now review all of the energy companies' grounds for removal — not just the federal officer ground. If the Fourth Circuit finds any valid basis for federal jurisdiction, Baltimore's climate lawsuit stays in federal court. If every ground fails, the case goes back to Maryland state court to be litigated on the merits. The Supreme Court expressed no view on whether any removal ground is actually valid.
What this does not decide
The Court decided nothing about whether the energy companies' removal was actually proper on any ground — that question goes back to the Fourth Circuit. The Court also left open whether fee and cost awards under the remand statute are independently appealable, noting that question was not presented.
Concurrences and dissents
Dissent — Justice Sotomayor
Justice Sotomayor argued that §1447(d) permits appellate review only of the specific removal ground Congress singled out — §1442 or §1443 — not every other argument a defendant happens to bundle in. She pointed to an unbroken line of decisions from eight courts of appeals over nearly half a century all reading the statute that way, and argued Congress implicitly endorsed that consensus when it amended §1447(d) in 2011 without disturbing it. She warned the ruling would let defendants manufacture appellate access by tacking on weak federal-officer arguments.
How the Court got there
The legal reasoning, step by step
- The Court started with the text of §1447(d), which allows appellate review of 'an order remanding a case' when the defendant relied on §1442 or §1443 as a ground for removal. The key word is 'order' — a court's formal written command. The district court's single remand order here rejected all five grounds for removal before sending the case back to state court.
- Federal courts cannot simply shed a case from their docket by choice; they are obligated to exercise jurisdiction when it exists. That meant the trial court could only issue a remand order after examining and rejecting every removal ground the companies cited. So the remand order necessarily encompassed all of those grounds, not just the §1442 argument.
- A case is removed 'pursuant to' §1442 whenever the defendant's notice of removal cites §1442 as a ground — regardless of how many other grounds it also cites. Congress knows how to restrict review to cases removed 'solely under' a particular statute (it did so in a neighboring provision), but no such 'solely' language appears in §1447(d).
- The Court leaned heavily on Yamaha Motor Corp. v. Calhoun (1996), which held that when Congress grants an appeals court review of a district court 'order,' it grants review of any issue fairly included within that order — not just the specific legal question that triggered the appeal. That logic applies with equal force here.
- The Court rejected the argument that lower-court decisions reading §1447(d) narrowly had created a 'broad and unquestioned' consensus Congress silently ratified when it amended the statute in 2011. The Court called those decisions a 'smattering' of opinions and held that the statute's text and structure pointed in the opposite direction.
- Policy concerns — that defendants would game the system by tacking on weak §1442 arguments to get full appellate review — do not override clear statutory text, and Congress has already addressed frivolous removal through cost-shifting rules and court sanctions.
