It was a little bit of an odd case to begin with. The idea is kind of that there's a cause of action around state policy creating an inter-state "nuisance" in arguable violation of federal law, but there's no real precedent for that kind of thing in common law, and certainly not in statutory law.

If one were to establish such a cause of action, it would have major implications around things like differing environmental regulations, firearms laws, labor laws, tax policy, welfare, heck even fireworks sales.

I'm not surprised the SC didn't want to leap into that giant legal cluster headache.
