My comments were in relation to the CAS case where the limitation was implied by a UEFA rule, however the start point to measure that limitation period was not clear. It doesn't bring any significance to the PL case which is implied by UK statutes of limitation.
Your response while correct in parts seemed a little muddled. For clarity
Limitation periods start from the date of the cause of action, the first date at which a claim might be able to be made and usually the date at which there is some evidence of wrongdoing or when that evidence came to light.
It may be that each party will again argue the date from which this period is measured backwards in time and a possibilty that different charges in the list of allegations have different start dates. I'd probably like clarity on that from our more learned friends, it's quite possible there may be precedent case law that definitively states when, in such arbitration cases, the limitation starts from.
If we were to use the date we were charged by the PL 06.02.2023 on the face that statute will import limitations on anything prior up to 05.02.2017.
There are of course exemptions to this, one being "deliberate concealment"(fraud). Which on the face of things the PL must prove to the required standard if the IC is to consider the older allegations.
Section 32 of the Limitation Act 1980 states that “any fact relevant to the plaintiff’s right of action has been deliberately concealed from him by the Defendant” the 6 year period for bringing a claim does not start until the Claimant has discovered the concealment, or could have done so with reasonable diligence.
The term “deliberate” means that the fact has been concealed by a positive act of concealment or omission or withholding of relevant information. This means the Defendant must have known that he acted in breach of duty before he can be accused of deliberate concealment. This is a difficult hurdle to overcome. I suspect City will argue this point unreservedly. I cannot see where the PL can possibly satisfy this requirement in respect of Mancini or Fordham and even if they could, the Leicester finding now put the contemporaneous rules as read as a determining factor, which makes the Mancini allegations moot as no such rules, as made out in the allegations, regarding contractual disclosure, were in place.
