I'm not sure of the technicalities of this one, but surely full disclosures of all relevant documents have to be disclosed to both sides well in advance of any hearing, for the judge to decide what is and isn't permissible in court.
The point of the discarded email was laboured a great deal today, so you do have to wonder whether both sides have had sight of these by now. I'm agog to hear what the IT expert will say when that time rolls around.
NC has carefully laid some foundations, IMO. She's too competent a lawyer to lead witnesses down false garden paths, and Lawyering Rule #1 is never ask a question to which you don't already know the answer. Also, the tactic of giving KS a platform to smear SP without a scrap of supporting evidence was a master stroke. Hostility to SP, blatant dishonesty, sheer incompetence and failure to follow routine procedure - against the advice of their own HR - all skilfully revealed. And even then bettered by NC's conclusion: 'You're intelligent, aren't you?', as if anyone is ever going to answer 'no' to that question.
Intelligent - yet still managed to fuck up on such a monumentally incompetent, deeply spiteful, over-personal and mendacious level.
In awe. What a very clever piece of lawyering.
