SAN FRANCISCO — The U.S. Supreme Court’s Anna Nicole Smith decision, which limited the authority of bankruptcy courts to decide the fate of certain claims, has put an unexpected wrinkle in Heller Ehrman’s bankruptcy.

Sixteen firms fighting the Heller estate’s Jewel v. Boxer claims over fees from unfinished business asked earlier this month to move their cases from U.S. Bankruptcy Judge Dennis Montali’s court to district court, citing the Supreme Court’s June decision in the Smith case, Stern v. Marshall.
