I think COP would be taking an awful risk if they waited for the PE dispute to go all the way through arbitration. COP could be liable for hundreds of millions to both WPL and FAR. I imagine WPL would go rather litigious if the outcome cost them any time, money or position. The saying " you can't unscramble an egg" is all too true here for COP. I wonder who at COP decided to let this slide for so long?
One comment at the AGM regarding the PE dispute was that ' its a big mess' qualified by 'a beautiful mess', meaning that from FARs position COP has got themselves in a mess that could be advantageous to FAR.
FAR has been investigating possible downsides to proceeding and has come to the conclusion that it has nothing to lose and a good chance of a gain.
