Please help with my dilema.

My sister used to date a guy, but he became psycho and so she had to end the relationship. He was crazy for a while, stalking her, calling her, and bordering on threatening her. Well, she ignored him for almost a year. The problem is that I play volleyball with her and he is also on the league. It's been odd, but OK, because he is on a different team. However, he started calling her names (the worst one you can call a woman!) and getting mad. She filed a complaint and the league reps said they were going to give him another chance and that if he acted out again they would not allow him to play. During the time between when he called her the disgusting names and when the league decided to let him still play, neither I nor her would shake his hand after the games. He filed a complaint saying we were unsportsmanlike. Now the new new season is starting and the sign-up sheet says we all have to abide by sportsmanlike conduct. Can they make me shake his hand? Is it actually unsportsmanlike if I only don't shake his hand??

Help me with my dilemma!!! Thanks!!!!

Not if you are open about your reasons mate, they would look rather silly doing anything about hand-shaking.

If you adopt a sportsmanlike attitude to games with him in, and treat him as any other opponent whilst the game is on, they really cannot force you to shake hands with someone in this situation.

Good luck with a messy spot.

Well it's going to look like it if everyone else is doing it and you guys aren't.
Maybe you need to grit your teeth and get on with it - or at least gesture as if you're going to - that way, if the stalker guy refuses, it's him that's going to be regarded as unsportsmanlike and potentially get kicked off the team.

I'd be open with the league about your specific problems with this bloke- it doesn't sound like he's exactly being sportsmanlike or being a nice human being either. It's not like you're not going to shake hands with everyone other than the person who's been threatening a member of your family, is it?

unless you have signed a document stating that you will abide by this rule then they cannot make you do anything at all

Not wishing to be flippant but you could always do what Sebastian Coe did when Steve Ovett beat him at the Olympics, stick your hand out but ostentatiously look in the other direction.

I wouldn`t shake his hand. His neck, probably.
