There is a discussion at the place where cowards post, fencingsucks, about integrity and refereeing. Due to the size of the fencing world especially in weapons with smaller numbers like saber, all the fencers in an area know each other, referee or not.
If you fence occasionally with someone at a club who is a referee, should that referee not direct your bout?
What if it was several years ago? Should that referee no longer be able to ref a bout?
What if a fencer is visiting a club and someone from that club gives you a lesson, can they no longer be your ref?
What if they are from a club that hates your club? Should they be your ref?
What if the ref was a coach at a club you fenced, but did not belong to and they gave you a bit of advice? Ineligible?
What if you are a referee and another referee who is more experienced gives you hints about hand signals? Can that ref in the future direct your bout?
How long should a ref have to be away from a club to ref someone from that club?
What if a referee just admires a fencer, they know how hard they work and how far the fencer has progressed, does that make it unethical?
How about if the ref is someone who knows your family? (Not come over for dinner know them just say hi how are you know them) Should they refuse to ref bouts?
What about refs with preconceived notions? Perhaps knowing that a particular fencer has a bad temper and tries distracting behaviors, should the ref remove him or herself?
