Actually, the court's view/presumption (which is rebuttable) is that the government bodies are acting in concert, and within the constitution. The only time the courts want to be involved is when an entity OUTSIDE the government makes a claim.
When George Bush's administration created a new court (the constitution give court creation to Congress), the courts did nothing until a person who was IN that court, sued with an argument that the court was unconstitutional, because it wasn't a creation of Congress. If Congress had sued Bush for creating a court, SCOTUS likely would have said "no standing, and we know of no injury to the people on account of this court."
Congress punting to the courts is because Congress wants zero accountability. Same reason that Congress creates agencies. This way, nothing that happens is Congress's fault.
Take Obamacare for example. Pelosi said they had to pass it to see what was in it due to this standard operating procedure of writing laws by staff as opposed to Congress-critters. She was at least truthful when she said this. Everyone thinks she's an idiot for saying this but it is fundamentally true.
No, most here know that I am no supporter of this HAG but it was in fact the most truthful thing I've ever heard her utter. Must have been the botox!
But no one seems to care. The only one I have seen who rails against this is my Senator, Jeff Sessions, Republican (conservative), Alabama. When he was opposing the numerous amnesty bills he used a thousand plus page law as a prop and said, paraphrasing, “Congress should NEVER pass a bill they cannot read in one day.”
Anyway, any bill that large is going to have all kinds of unintended consequences that leave it wide open to the courts and bureaucrats to decide what it means, which means we are pushed further into tyranny and makes us all lawbreakers without even realizing it.
Before I retired from the Air Force I was on a HQ's staff and we were required to write position papers and rules that only had one page. All the supporting information was on appendixes, but the General wanted all the facts simply stated up front. If you couldn't do that, it was his belief you hadn't thought it through enough, and he was right. Do that too many times and you'd get orders to Greenland!
