I agree with most of the comments on this forum that an appeal by NZF is unlikely to succeed. I also said earlier that NZF was negligent regarding Wynne (and Burfoot), assuming these guys are worth a call-up to AWs.
But let's for a moment assume that there is some kind of a catch that we don't know of - whatever it is - that has now been pulled out of the trick bag. Let's make a wild assumption that OFC is found to have been wrong in chucking us out of the Pacific Games / Rio qualifiers.
What would happen then? My guess is it (OFC) would never pick itself up off the floor after that.
And FIFA would never let that happen since they want to preserve OFC as a valid federation.
So my guess is that - no matter what the outcome is - we're fudged.
