In my state you absolutely CAN personally be sued for any "pain and suffering" Susie endured from being unjustly cut. Happened to a fellow teacher (not over cheer but a classroom incident), and the legal fees were tens of thousands. No one is saying put everyone on a squad, far from it. I am just saying that it is to your benefit to have objective outside judges when you have to fight to maintain the integrity of your tryout. We DIDN'T cave to Susie's mom, and were able to stand our ground because we had scores to back the decision. We DON'T cave to parents. We don't have to because we have a fair tryout process that relys on the most objective scoring process we can get. If you don't have that, then you are going to face challenges that will be difficult to defend against. The reality of the situation is that lawsuits cost a LOT of money to defend against. School systems will usually cave if they think there is a chance the parent will actually sue. If you have concrete scores to show Susie's mom, that admin, and the lawyers, you can usually head that off and stand your ground. "We just didn't think she was a good fit for the team" doesn't really work and ends up with you taking everyone that protests.
