Summary: written with AI from the case record.

What it's about
The Supreme Court considered how much of a remand order a federal court of appeals may review when removal was based in part on that statute.
The case is a procedural fight over when a lawsuit about fossil-fuel environmental harms can move from state court to federal court.
Question presented
Whether 28 U.S.C. 1447(d) permits a court of appeals to review any issue encompassed in a district court's order remanding a removed case to state court where the removing defendant premised removal in part on the federal-officer removal statute, 28 U.S.C. 1442, or the civil rights removal statute, 28 U.S.C. 1443.
What the Court decided
Holding
The Fourth Circuit erred in holding that it lacked jurisdiction to consider all of the defendants’ grounds for removal under §1447(d). 952 F. 3d 452, vacated and remanded.
- Result
- Vacated
The vote
From the opinions
“Civil defendants in state court may remove a case to federal district court by asserting one or more bases for federal jurisdiction.”
What's next
The Fourth Circuit will now examine the companies’ stated reasons for moving Baltimore’s case to federal court. The case’s final location and the environmental claims remain unresolved.
Why it matters
It leaves open where Baltimore’s lawsuit will proceed and whether its environmental claims will succeed.
