We didn't cover that in law school.
Oh come on. You're being deliberately obnoxious. I can appreciate the humor of it (I can be obnoxious for kicks, too), but the details are fuzzy.. You know full well that in a common law system cases establish precedent, and that precedent is universally binding if it comes from SCOTUS. Thus, SCOTUS has the de facto position of being able to create law through cases. It may not have that authority de jure, but the mere fact that the concept of judicial review as we know it was established in Marbury vs. Madison---case law!
Thus, SCOTUS as we know it today basically created itself.
Sure, a few legislative remedies exist (expanding the Court like FDR attempted, for one), but we tend to defer to tradition (i.e. precedent), even when it isn't binding.
There is, however, almost nothing to stop SCOTUS from taking a activist approach that reinterprets part of the Constitution to fit an agenda (cf. Wickard v. Filburn). Plus, with the principle of Chevron deference for federal agencies, SCOTUS could go out of its way to make an activist-friendly decision.
I'm not saying that SCOTUS will invalidate Amendments. It can't do that. What it can do is validate laws that violate those Amendments and strike down those that uphold them.
So can they make law? Not directly, but they can use perfectly-crafted cases for which they can grant cert and can then rule as they wish.
