The overcoming clause

I saw that the rabbi wrote about the overcoming clause that it exists in other democracies and that there is no obstacle (in terms of the theory of democracy) to maintaining it here (but if I understood correctly, the rabbi opposes it in the current constellation).
My question is why is this acceptable? In fact, this break only exists in Canada, and there is a much stronger system of checks and balances than there is here (if there is an increase in 61). And checks and balances are an essential part of a democratic regime, and if Israel does not have a mechanism of checks and balances, I fail to understand why we will remain a democracy?
That is, a clause of overriding power can be a democratic act in government system x and at the same time be an act that makes a regime undemocratic in regime y. Does the Rabbi disagree with this claim?
 
Thank you Rabbi for the site, it's always fun to read.
