Stern v. Marshall
Stern v. Marshall, 564 U.S. 462 (2011), was a United States Supreme Court case in which the Court held that a bankruptcy court, as a non-Article III court (i.e., courts without full judicial independence) lacked constitutional authority under Article III of the United States Constitution to enter a final judgment on a state law counterclaim that is not resolved in the process of ruling on a creditor's proof of claim, even though Congress purported to grant such statutory authority under 28 U.S.C. § 157(b)2(C).
