Institutions may change their form, but not their purpose. For example, in USSR the judicial system was basically a tool to justify decisions of prosecutors and party leaders. Nowadays the judicial system of the Post-Soviet countries remains the same. It's a servant of the current political elite.
I don’t know if that’s a great example because that just seems like all judicial systems across all of human history. The protoconcept of judicial process probably arose from subsistence farmer communities needing a way to hypocritically expel or kill people who did not conform to religious decrees, but without losing any social status, and in fact gaining social status by association with the judicial system.
What we have today is a tiny, tiny, tiny modification of that, where our savanna-adapted meat brains put in accoutrements of due process and fair trials, but it’s all just for show so that political elites can say one thing (freedom, due process, fairness) but do another (court packing, systemic racism, regulatory capture, corporate shilling).
