It depends on what you mean by "actually."
In a pragmatic sense, whatever the U.S. Supreme Court says is constitutional is "actually" constitutional.
Perhaps you mean, "Should it be constitutional?" Well, obviously there are arguments on both sides -- and they were raised in Marbury v. Madison -- but I would have to agree with the Supreme Court: What would REALLY throw off the balance of powers is if there were no checks and balances to prevent Congress from passing unconstitutional laws.
Finally, perhaps you mean, "Was this what the Framers intended?" Again, this was argued in Marbury v. Madison. Probably the answer would be that some did, and some didn't. However, what is the point of writing a constitution that limits the powers of Congress if there's no way to enforce the limitations?
