Different Names

Where I came from those who hold life time position regardless of what they do are called dictators. Apparently those are known as federal judges here.  

The Chief Judge

And do not forget about the chief judge of that appellate court whom the actions of his clerk do not keep confidence that the chief judge of that court minds that in his court there were orders lacking stating who issued them or  the wide range of overstepping authority with which the clerk of his court issues orders.
