If the chief justice wants to write law, let him run for congress. His job is to call the balls and strikes, nothing more.
You are correct - it is well settled that the Court cannot rewrite a contract or statute to make it legal or enforceable. There is what is known as the “blue pencil” doctrine which holds that if the offending provision can be specifically stricken without effecting the rest of the law/contract then the court can do so. If it can’t the the entire law/contract is held unenforceable.
No, they will not rule against it and even if they did the good liberals in Congress known as the Republicans will re institute the subsidies and keep obamacare alive.
The fix is in...
