Bureaucrat

A bureaucrat neutrally executes a process without involving any of his or her own judgement except in minute details.

Wikipedia uses this term to describe those with sysop status on more than one project, who are trusted to execute the sysopping protocol (how sysops come into being, and cease to exist - although the latter NEVER happens on Wikipedia which is run by a cabal). There is a list of them at m:bureaucrat. Supposedly, they lose this status for abuses. But since the list includes several known abusers (Daniel Mayer, "Angela", Tim Starling and others) who always support the sysop power structure or usurpers (like the developers) it is not clear that anyone will ever lose bureaucrat status. More likely, they will flaunt status as a bureaucrat to "prove" that they have not abused their power, when they have.

The British TV series "Yes, Minister" and "Yes, Prime Minister" are about the way bureaucrats steal power.

Consumerium may be able to more correctly implement this with a political faction level that would actually put representatives of the users (and to a lesser degree the contributors) in charge of the bureaucrat activities.
