Sir, could I just add by way of where we are on this, I very much bear in mind the Tribunal's indication earlier as to the position it would be in if we asked for this issue to be resolved. This isn't a pleading point. It arises, let's take "power on" for example, where the four issues in the statement of claim relied on for "power on" are supplemented in the reply by another, let's say half a dozen matters relied on, which then bring in, on the documents attached, I think 19 lever arch files of further information.
