What happens if one state in the US won't abide to a federal law?

I’ve started to wonder if any sort of movement might arise for a constitutional amendment limiting the Commerce Clause. If worded in the right way, I could see such a thing plausibly passing in 3/4 of the state legislatures.

Huh, I would have thought that Texas would have turned down Federal assistance out of principle. Besides, Texas already has a retired shuttle.

The decision itself outlines the legal arguments succinctly. This is a rare case in which a competing constitutional amendment is at issue. The general principle that the federal government can do this if it meets certain standards and not in odds with a specific constitution provision, and seven of the nine said it was not in violation.

The general welfare power also appears in Article I, Section 8.

During an earlier “energy crisis” there was a federal mandate that each state set a speed limit of 55 mph on all roads. One state – I believe it was Wyoming – said fine, we’ll do it. However, the feds could not mandate the penalties for violation. Wyoming set up their law as an energy-saving device. Violation of it was $5.00 or so for failure to conserve natural resources and was not considered a moving violation, no points on one’s license, etc. In addition to this there was an extreme paucity of state troopers so one’s chances of being stopped were between slim and none. And Slim just left town.

I assume you didn’t mean to say that only one state agreed to do it, which is how this reads. Lots of states agreed, and most of New England actually reduced their speed limits to 50 mph.

Thank you, my comment was poorly worded. I believe that every state did implement the law in some form. I just knew about this particular case because my sister and brother-in-law were traveling there at the time. And IMHO it made sense in that situation, where you have hundreds of miles of sparsely-traveled highway.

Going back a few years the Texas governor has flip flopped on his hatred for the feds, but now wants the feds help.

Thank you for all the very interesting replies!
