WILMINGTON, Del. AP – A Delaware bankruptcy judge on Wednesday refused to cede control over a dispute between Washington Mutual Inc. and JPMorgan Chase & Co. involving billions of dollars in bank assets.

Judge Mary Walrath denied requests by the Federal Deposit Insurance Corp. and JPMorgan to stay two adversary proceedings in Washington Mutual’s Chapter 11 case, or to transfer the dispute to a federal district court in Washington, D.C., where Washington Mutual has sued the FDIC.
