SCOTUS granted itself that power. Their originalist powers are extremely limited.
So do not listen to justices that claim to be "originalist". SCOTUS authority to strike laws is self dealing and not at all an originalist power.
The original expectation was the public would demand such change via elections every 2-6 years and remove the corrupted Senator or Representative.
SCOTUS is not supposed to have power over theoretical cases yet it operates on concepts all the time. Just another way in which the system is rigged; the appeals of originalists who have clearly read the words, they're plain English, are just more self dealing power away from the public to the elites
This is just not true. Yes the SCOTUS ruled that it had the right to judicial review, because that's what the constitution said it had the power to do. This isn't "granting itself that power" anymore than Congress granted itself the power to pass laws or the president granting themselves the power to execute laws.
