Gawd only knows what you are smoking.
The U.S. Constitution already "threw" immigration legislation to Congress. The president has a role in enforcing and implementing the law, but not in making it. He has no authority to unilaterally decide that a certain class of people are no longer subject to laws enacted by Congress.
Your statement as cited below is totally jaundiced, legally obscene, and ignorant:
"I’m not so sure a conservative Supreme Court would want to throw the executive branch to the congress where there are 535 different opinions on legislation."
It is not for the Supreme Court to want or not want a legislative issue to be before Congress regardless of whether there is total agreement or disagreement. That is for Congress to work out per the Constitution and the political process. If they enact something that is constitutionally suspect then the courts are there afterwards, but when Congress is acting within its Constitutionally assigned area, it is none of the Courts business what they would or would not like to see for legislation or their responsibility help Congress avoid disagreement within its process.
Gawd, just stop. Just stand down and stop embarrassing yourself. You are into some real loopy stuff there.
