That is what I've always thought, and that's the way it should be in my opinion.Quote:
No. By its very nature an amendment is constitutional.
But there is precedent in other countries for what is being called "unconstitutional constitutional amendment doctrine." Here are two of the countries in question (and note that India borrowed heavily from the U.S. when drafting their constitution):

Going back to the U.S., I trust that SCOTUS would honor the will of the people, considering how much consensus it takes to pass a constitutional amendment (2/3 of House and Senate + 3/4 of States, or Constitutional Convention). But there is technically nothing stopping them from striking an amendment down, or at least attempting to.
Remember, SCOTUS gave themselves the power to strike down unconstitutional laws in Marbury v. Madison. Nowhere in the Constitution does it say they should have that power. So I don't think it's very far-fetched to envision a scenario in which SCOTUS tries to expand that power to constitutional amendments, especially if the amendment in question is imposing term limits on them. That would be the worst-case scenario.
Here's an academic journal article on this topic from a more reputable source, the Maryland Law Review.
