At the heart of this case is a fine point of law: whether the EPA’s decisions to reject Oklahoma’s and Utah’s air-quality plans should be treated as separate, local actions or lumped together into one big, national rule. The Supreme Court said these are individual, state-by-state decisions, based on detailed, local facts—and so they belong in the regional courts, not in Washington’s D.C. Circuit. In this case, the Court determined that the EPA's disapprovals of state plans remained separate state-specific actions, despite being published together, and therefore challenges should be heard in the regional circuit courts.
