Nice try Rats, but i think when it all boils down, all the PRL are doing is implementing an agreed condition within the Premiership which is a binding contract and follows the Law as per the IRB's own Regulation 9 covering the agreed upon release of players from their domestic obligations for International matches.
So dont blame the PRL....blame the IRB.
Hold on, there is an agreed international window, if a union sets up a game outside that window they cannot expect the players club/region to support this, its an unfair demand.
You guys are missing his point.
If the clubs wanted their players playing international rugby, they would be encouraging George North to play for Wales; irrespective of the IRB window.
The question you need to ask yourselves is; "if there were no IRB window, would the club release the players if there was no clause in the contract?"
Another question you might want to ask yourselves (and I suppose, all the rest of us ask ourselves too) is; "would I want my club to...?"
[and for the latter, as regards myself, I have to admit... its far from an immediate "yes"!]
