Here is the opinion in Keepseagle v. Vilsack.
An excerpt:
Appellant Timothy LaBatte, a class member in a class action against the United States Department of Agriculture (“USDA”), seeks to intervene in that class action – despite the fact that the action was settled and closed – after his claim for compensation under the terms of the action’s settlement agreement was denied. We affirm the District Court’s determination that it lacked ancillary jurisdiction to hear Labatte’s challenge. We do so because LaBatte’s motion to intervene is unrelated to the underlying lawsuit and because the District Court was not required to hear LaBatte’s motion in order to effectuate its decrees.
