That particular part of the Act, Sec 1501 is rules unconstitutional. As such, it is unenforceable.
Now the US has two options: To appeal the decision (which is likely) and/or to try to get Congress to re-draft it.
The second option is the cats meow because if it goes back to Congress, Congress will probably repeal the whole damn mess!
