The Policy of enforcing unsigned amendments is a NZ thing.
You sign a Contract and then they change the rules.
They even make NZ'ers sign really bullying contracts - or no job.
This is a corrupt enforcement.
If Israel didn't sign any 'added' small print extras added on, then they won't hold up in Court, etc.
I've worked a few jobs where they've changed Policies, etc and I've always had to (by choice) sign the 'updated' extra bits or not. Most of them are pedantic and of no real importance.
So basically 'Sport' (now ruled by the Media) in Australia is ANTI-CHRISTIAN in its stance - no?
You might find that if the rest of the players (nearly all are heavily Christian, regardless if they are yellow Pineapple Polynesian, black Coconut Melanesian or whatever) revolt and stand by Israel, then the 'spill-over' effect will begin into other codes of Sport.
Israel is an exceptional 'new standard' of Australian Sportsman - he has played AFL, NRL & ARU.
