You all need to step up together and write letters to the director of the PAL and your own league director. You can't be afraid to step up. It's important to do what's right by all the kids. They have to act if there is a problem. If there are no concrete issues you may have a difficult time having him removed. If that's the case the group can ask for a release of their child to play somewhere else. Or if they don't get rid of him, don't play PAL. Play on a low level travel team like Mamas boys where it's affordable and your sons skills will still improve.
