This ruling doesn’t sound like anything major.
It's all wrapped up in the same case, now in the U.S. Court of Appeals for the District of Columbia Circuit. The court below found the payments unconstitutional.
I don't know that this ruling, on it's own, is major. But it does signal that the Courts are willing to force the payments to continue to protect some state interest, after the courts said the payments were unconstitutional.
Obviously, the courts are lawless.
