Re your first para, that isn't really true. I agree entirely, no way in this case, but worth distinguishing possibility against likelyhood. It is in theory (and that is why i said theoretically) possible for any party to know, as soon as a decision is reached, for which there is no minimum or maximum time.
It isn't relevant, as such, other than when we all make a point of what we think of when the club could or couldn't possibly have known. The truth is, they could have known at any point in time.
Re the rest of the post, neither here nor there. Worth reading the cas procedure, then what i said. Which i stand by. It is My interpretation, May be wrong, but certainly not impossible nor can anyone convince me that it is not plausible.
