I'm not just someone "on this website," I'm a Harvard-educated lawyer in the federal government with over a decade of experience, including litigating Constitutional issues in federal district court. I assure you, there have been years and years of "further reading" and it was emphatically required.
It's a trendy take to say that judicial review isn't in the Constitution, and that may be superficially true, but it ignores two important facts that contradict that take:
(1) Article III's explicit grant of "appellate jurisdiction ... as to law"
(2) The Framers' own words in the Judiciary Act of 1789, which explicitly anticipates cases "draw[ing] in question the validity of a treaty or statute of, or an authority exercised under the United States, [where] the decision is against their validity" and reaffirms that such decisions may be "reversed or affirmed in the Supreme Court of the United States."
It is very clear what "appellate jurisdiction ... as to law" in "cases, in law and equity, arising under this Constitution, the laws of the United States, and treaties made" means. And for anyone who has any lingering doubts, just look to how the Framers implemented it in the very first Judiciary Act, less than seven months after the Constitution went into effect.
