There was an article in one of the broadsheets (I forget which one) after the ban was announced in February, where they interviewed three barristers, who looked at previous CAS decisions and seemed to agree that based on previous form the most likely outcome was that CAS would reduce the ban to one year. At the end of the day arbitration is about finding middle ground when two parties disagree about something. However, I think this will be more binary, either City get off, or they'll be done!
Anyone got a link to this article - sounds interesting.
Arbitration is not about finding middle ground - mediation much more about that.
FWIW my view remains that if CAS accept the allegations are "proven", 2 years is not unreasonable or disproportionate. To get to that point, CAS would have to accept an element of deception and concealment by City, that this is a second offence having been given a second chance (afforded by the 2014 settlement) and that the scale of the breaches were very significant and over an extended period. In that set of circumstances, its hard to see why they would interfere with the punishment.
So the only way, in my mind, that CAS gets to a 1 year ban is saying that only some of the breaches are time barred but that 2015/2016 offences are still "triable". The problem in that is that it would still be a second offence so it is still serious and could well justify 2 years. It would also mean, in effect, that they accept City concealed and misled UEFA in 2015/2016 and the ending of the settlement regime in 2017 was on false grounds. These are all serious.
Finally, let's say CAS sides with City on the substantive or rules based arguments leaving only the allegation of non-cooperation. Firstly that is a subjective matter and if City did not cooperate it would have been on the edges. On a standalone basis, I'm not convinced that warrants a ban at all - possibly a small nominal fine.
In short, I just don't see many ways in which CAS can fudge it to a 1 year ban, far more likely an all or nothing. I think Sam Lee was clear he doesn't know and was largely guessing although lots of people have jumped on the 1 year bandwagon.
One final thought, a settled 1 year ban on the basis that City don't accept the wrongdoing is not the same as a 1 year ban after CAS find that City breached. The latter still leaves the club open to a few issues eg PL. If they can see 1 year, they should find a way to settle if need be by threatening all sorts of further legal action (even if only tactically).
