@sickburnbro @Elliptica "If a judge doesn't follow the rules, what good are they?"
Indeed, but that doesn't say deleting the entire institution is a good idea.
Even the "pure one-man fiat dictatorship" suggested by @TrevorGoodchild for anything larger than a village is going to have to delegate judicial power so he won't have all his consumed by all the cases that arise.
I mean, is Stalin going to be presiding over every domestic dispute?? Yep, the USSR had a family court or civil/criminal courts that handled that end of things. And you need a judicial system to avoid "self help" and the resulting blood feuds.
Dictatorships also don't solve the succession problem, and that of course includes monarchies, there's even wars named after this like War of the Spanish Succession.
Perhaps take many steps back and assume any given "good" political system lasts only so long at maximum? Even those monarchies underwent various changes, right? Magna Carta for example.... Formal term limits for systems of government?????? :cirno_shrug:
