Obama proved with multiple of his EO's, that the damage is done long before it finishes going through the courts. Many things could not be reversed at that time.
Will the Supreme Court actually overturn the laws?
I am not claiming the laws you refer to are Constitutional. I am suggesting the Supreme Court doesn't always overturn unconstitutional laws.
In addition, even if they do, it won't be 'in a few months'. More like a few years.
