Any relevance in the timing? I am surprised the club didn't either i) do this immediately in November, or ii) wait for the final judgment on the first arbitration.
Is it just due to the tribunal making it known last month that they wouldn't consider the November amendments in their final judgment? In which case, this was the first "opportunity" to raise the action?
I suppose, for all we know, the club may have raised this with the tribunal in November but it took till January for them to respond?
