Who is to judge?

Think hard about this topic, because we rely on strong individuals to pass judgement for the collective of society. But when these judges abuse their powers, it becomes incumbent that we- the people - take back the reigns of power that we loaned to our government. In paring back gubbermint structure (and cost), we must first decide on criteria. So I ask, how do we determine who gets to judge.
Transparency is necessary, as is representation. I have some ideas, but they are for later. For now, I kick out a query and solicit response.

Ten metrix points for the first answer eminating from a 2005 Science Zone participant in each classification - scientist, agent, conduit, teacher and student. The term agent means designated agency researcher or project leader.

Redile theory used the term researcher for agent - a misnomer because of the poor connotation of 'research' in the general community. Research is complicated - but everybody can be an agent - even Maxwell Smart. But why fight K.A.O.S.
