They can set whatever rules they want for teams to be eligible and be able to host fixtures in their competition, and they do so to avoid a shambles like the Wigan Widnes debacle.

What sort of governing body allows a club to postpone a game, rather than have referee inspect and decide if the pitch is playable? That's right, the RFL.

The RFL are investigating Wigan for the unilateral actions? The RFL rules are very clear - why are you trying to paint what happened as their fault?

FWIW, clubs can own a ground but assign primacy of tenure to another side (as Leeds appear to have done in favour of the RU club even if in practice an RL game would never be moved for a RU one).

I've no idea what you are on about.
The Latics club said we couldn't play, why would they give a fig what some RFL bod has to say?

And the match was postponed due to the extreme weather, I didn't realise the storm was forecast last November?

The game was cancelled based on what they thought the pitch would be like after a forecasted storm. This in itself is laughable. Unless Athletic ordered Wigan not to play(can't see how they could unless Wigan's tenancy states they could) , then Wigan need to be punished heavily for bringing the game into disrepute.

RL always seems to shoot itself in the foot or in this case Wigan. They do something brilliant and beat the Aussies to become WCC then throw all that positivity away by doing what they did.
