Hey there,
Some of my colleagues are ultimate players. And they explained to me that they are no refs on site. Even at world championship level.
I couldn’t believe it at all! But it is true. Everything is self referred. Every situation is discussed between the 2 players concerned.
I dream so much of bike polo to be at this level of consciousness.
Some explanation Here
Very inspiring no ?
For that to work, players would have to know the rules.
I have heard of this and share your hope that we could have polo follow a similar path. It feels like most of this woes we worry about could be solved if we took a different approach to accountability. Not saying it needs to be the same but a model based off the base that Ultimate has made seems doable. I think it would be more than worth to workshop how it would work and get down to the brass tacks.
@Cleftintwain You could have some sort of EULA you have to sign before tournaments 
That inspires me!
I think I will try to attend a ultimate game see how it works.
Clefty has a point. However I think it is the case already now, otherwise you can’t play on the thin line between freedom/faulty and are either too careful or too dangerous. Plus, we use to know the rules to argue with refs (but we shouldn’t, or reasonably)
So I think the player’s knowledge is a point in both case.
Main point I have difficulty with, is linked to game format. Ultimate has the time (75 to 90min games) to settle thing. Main reason for having a ref in bike polo is to settle thing quickly in a ~15min game.
But in my case I think it could be a good spirit for our club’s pickups, that are today not even reffed.
