Wyoming v. Zinke, 871 F.3d 1133 (10th Cir. Sept. 21, 2017).

This case arose out of a challenge to fracking regulations promulgated by the Bureau of Land Management.  The Tenth Circuit abstained from exercising its jurisdiction based on the prudential ripeness doctrine because (a) the current administration had announced its intent to rescind the regulations, and (b) withholding review did not impose a hardship on the parties seeking review of the lower court’s decision.
