It depends which allegations you are talking about, imho. And what the allegations actually are. Proving an allegation doesn't automatically mean "knowing concealment" (proving fraud presumably does). And I am not sure a mistake, or a difference in interpretation on an accounting matter, if you will, is either as, if you believed you were in the right, then there could be no "knowing concealment".
Anyway, that wasn't my point. My point is that I have never heard that a tribunal process, as described by
@domalino , won't take into account the limitation periods of the Limitation Act in its judgment. I was asking, really, for his clarification on that and his reasoning. He may be right, the law is an ass, after all. But I very much doubt it.
