It was a majority ruling striking down the provision of Obamacare that would withhold all Medicaid funding to states that elected to not participate.
My recollection was that they did not make this specific, and thus made it general; and given that it's a favored federal tactic, I think the precedent is established for states that wish to push back in general.
@Weird Tolkienish Figure @r9etb The argument is that Congress cannot unduly pressure states to do something that should be within the discretion of states. They can "encourage" states to do something, but not "punish" them if they don't. So, depriving a state of
all Medicare funds because it refused to expand Medicare was too much of a punishment, and therefore an unconstitutional use of the spending power.
At the other end, the Court once held that it was okay to deprive a state of 5% of highway funds if they didn't raise the drinking age to 21, holding that that an extra 5% amounted more to encouragement than a punishment. I'm shorthanding this, but that's the gist.
What's a bit interesting about this, though, is that immigration is treated differently under the Constitution, and it really wouldn't be just a spending clause argument. Congress' power regarding immigration is
plenary - it completely pre-empts the power of states to regulate in that regard. So I think Congress likely could pass a law outlawing "sanctuary city" legislation or orders, and perhaps be able to enforce it via spending or other hammers. I don't think they could force
cooperation, necessarily, but they could take action against affirmative actions by a state or locality that violated/interfered with federal immigration law/policy.
It would be an interesting argument. Almost the flip side of the basis for striking down most of Arizona's immigration law. In any case, I think we'd all agree that Hickenlooper's statement:
"There will not be any deportation force coming into the state of Colorado," is meaningless. He can't do that, as Mississippi found out in the 60's.
