Can a state-law right underlying a claim be determined in a federal bankruptcy proceeding?

12 Claims litigation is, jurisdictionally, a hybrid. The state-law right underlying a claim can, if the automatic stay is lifted, be determined in state court. Jurisdiction over the state-law right is concurrent between state and federal courts. The actual claim, once a proof of claim is filed, invokes special bankruptcy rules and procedures that are created by the Bankruptcy Code and that are a matter of exclusive federal jurisdiction. See Wood v. Wood (In re Wood), 825 F.2d 90, 97 (5th Cir.1987).
