I have seen people saying that the government is doing something "unconstitutional", and yet the Supreme Court either ruled that it was constitutional, or never ruled on it at all (so the law remains valid and people will have to follow it). One example of something that someone might call "unconstitutional" would be, say, the idea that the United States President can wage a war "de facto" without needing to actually declare a war (which requires Congressional authorization) by just claiming he's the Commander-in-Chief and tell his army to invade a country. The only limit on this is the War Powers Act, which does require authorization for a military action by President after 60 days and for the President to inform Congress within 48 hours of the start of military operations. (In my search, I've seen that some people even argued even the War Powers Act is unconstitutional, because it put limits on the President's powers...so...yeah).
Thing is, thanks to the
power of judicial review, the Supreme Court acquires the 'de facto' power to interpret the Constitution: the Court has the power to invalidate laws that it finds unconstitutional, and thereby implicitly determine what is and isn't constitutional. If the Supreme Court does not rule on the constitutionality of a law, then I suppose there can be a debate over if a law is unconstitutional or not, but unless the Supreme Court actively intervenes to stop a law, then the law would still be valid anyway, so debate over "constitutionality" would be pointless. And if the Supreme Court
does rule on the constitutionality of a law, then it's clear that, due to judicial review, its word is final, and disagreement with the Court would appear to be pointless.
But I must be missing something. Why is the word "unconstitutional" being brandied about despite the fact that only the Supreme Court can realistically make a judgment about "constitutionality" thanks to judicial review.
EDIT: There is something I must speak up first, in the interest of discloure. I previously have said in past threads that the consitution gave the right to the Supreme Court to interpert the consitution. When I actually did the research right now and read said consitution, I realize I
was wrong; it was in fact Marbury v. Madison which did that. I must apologize for this "flip-flop", if anyone cares.
