That seems like a nation-level body? It seems unlikely we'd ever have something like that hiring judges for city-level posts in USA. Also JAC seems to recommend candidates after which action another (seemingly politically-appointed) entity decides whether they'll go on the ballot? I might be misreading?

I certainly hope we can improve our "judicial" system in USA, to make it more just, less tyrannical, less capricious, less totalitarian, less active, etc. Sometimes I wonder whether that's possible for a society that's happy to spend $750B/yr on killing machines and in fact has killed millions of innocents overseas over the last several decades. As Thucydides wrote, the tyranny that the Athenian empire imposed on others it eventually imposed on itself.
