"A plan opening broad swaths of western Colorado to oil and gas development is among at least 14—and possibly several dozen—Bureau of Land Management plans and decisions that environmental groups say they expect to challenge in the wake of a recent Montana federal court decision.

The U.S. District Court for the District of Montana decidedOct. 16 that William Perry Pendley, the agency’s former acting director, unlawfully approved resource management plans for the Lewistown, Missoula, and Miles City areas, even if a lower-level official under Pendley signed off on them. Only the agency’s director can make those calls, the court said."
