Those amendments are ridiculous.
It just reduces the power of the democratically elected parliament, and therefor the power of the sovereign.
What's the problem with that? There's nothing wrong with limiting the power of democracy and every successful liberal democracy has plenty of non-democratic elements in their institutional machinery. That's what constitutions are to a large extent.
I think these kind of amendments become the rule. They're as necessary as independent central banks. Otherwise current voters will keep screwing future ones.
