Just say you're running a club that is doing well and one of your regular players has a minor interstate matter to answer. The matter has been already put back to October to not interfere with the season. But there's a world cup on, the player wants to play in it, and so he gets his lawyer to ask the court about getting the date changed. They can do late August. So you talk to the NRL. If we leave it at October so he can play in the finals he misses the World Cup and his country needs him. So are you going to play the game or what?
If the answer is no, tell lawyer, look mate they won't play ball, leave it in October, the kid will just have to miss the World Cup or part of it. But it seems like the NRL did agree to play ball on this occasion. No brainer really.
That is what I imagine led to this decision.
