related to cases under Title 11. 28 U.S.C. § 1334(b); Bessette, 240 B.R. at 152-53. Federal district courts have original, but not exclusive, jurisdiction over bankruptcy cases. 28 U.S.C. § 1334(b). Jurisdiction is shared with the bankruptcy court, an arm of the district court, although the bankruptcy court can only hear cases that derive from the federal district court’s bankruptcy jurisdiction. Id.; 28 U.S.C. § 157. Although cases are often referred to the bankruptcy court for resolution, the district court may withdraw its reference to the bankruptcy court and hear the case itself. 28 U.S.C. § 157(d). Because the complain ankruptcy estate or affect the size of the estate, then the bankruptcy court lacks jurisdiction. See, e.g., Feld v. Zale Corp., 62 F.3d 746, 756-59 (5th Cir. 1995) (<HOLDING>); Community Bank of Homestead v. Boone, 52 F.3d
holding that bankruptcy court could not enjoin third party tort claims that would not affect estate holding that a bankruptcy court does not have exclusive jurisdiction over third party claims against nondebtor parties as such claims are not cases under title 11 holding that if dispute involves funds that are not property of estate it cannot be maintained in the bankruptcy court unless it is related to the bankruptcy proceeding which means it is likely to affect the debtors estate holding that thirdparty nondebtor claims must directly affect the res of the bankruptcy estate holding that bankruptcy court may enjoin federal administrative proceedings when they threaten the debtors estate
