Question presented

Whether the Second Circuit’s rule that a district court’s order is not a “final decision” under 28 U.S.C. § 1291—and thus not immediately appealable—unless it “adjudicates all the claims and the rights and liabilities of all the parties” conflicts with this Court’s precedent and the rules of other circuits.

What the Court decided

Holding

Petition DENIED. Justice Sotomayor took no part in the consideration or decision of this petition.

What's next

The Supreme Court's action on this petition is complete, and the Second Circuit's ruling remains in place for this case.
