Easier said than done. A few years back, I confronted the organizers with a question about a team's players ages. I was blown off.
Because there is always another way to get your point across; I had a brief conversation with one of the high profile parents of that team (one who allegedly had a child of age and older playing). In that conversation, I stated I heard before the playoff games started they were checking rosters. (the rules of the tournament stated you needed to submit paper copies of the roster and carry a copy on you). He quickly and politely excused himself and said good luck.
Miraculously the boys in questions were not there for the playoffs. Sad part was, they didn't need the older players to win.
