Decide the small question, leave the big one
A judicial-restraint proponent would argue —The First Circuit did this case the right way. Gordon-Darby sued under a provision that authorizes citizen suits against parties "in violation of" the Clean Air Act, but at the time of suit New Hampshire's repeal had not yet taken effect — there was no present violation, only a forecasted future one. That statutory mismatch is enough to dispose of the injunction, and once the merits tilt against the plaintiff the irreparable-harm analysis follows naturally. There was no need to reach the constitutional commandeering question, and prudence counsels against doing so when a narrower ground resolves the dispute. Courts husband their authority by deciding only what they must; the panel's unsigned order is a model of that discipline.
