Well the Poser:  good or spawn of evil discussion aside, I do believe that a group of people can fairly judge for their own speciality, BUT!  (You knew that was coming!) 

I would like some clearly defined guides for people to discuss the judging with the judges. 

Those could be simply a thread where the people wanting to know why they were rejected (or accepted) can ask the judges what's up.  With, of course, the caveat that web manners are fully in effect:  The judges don't need to be screamed at for being elitist pigs, and the candidates don't need to be looked down on for being "new" or whatever.
