Litigation? Clowns
You sign waivers for a reason. If you think it’s unsafe then don’t let your soft kid play.
Waivers won’t hold up when it is shown that the tournament allowed overage kids to play. It hasn’t been contested yet, rest assured it is coming. Blatant disregard for players safety, negligence on both club and tournament.
Probably could also persue a lawsuit against the 18 year old playing 16 year olds, assault and battery, adult on minor.
