30 It is therefore clear that there is not one scintilla of evidence to support the allegation, in the defendant's counterclaim, that Mr Hanlon and/or Harwood Andrews were "intimately involved" in the theft, which he alleges was committed by the plaintiff on 16 November 2007. There is no evidence, whatsoever, of any involvement, whether direct, indirect or otherwise, by Hanlon or Harwood Andrews, whether acting in concert or otherwise, in the taking of the documents, mobile phones and the like which occurred on that day. The unchallenged evidence of the plaintiff is to the contrary. As I have already stated, the defendant has demonstrated that he has a good appreciation of the principles of Browne v Dunn. He made no challenge to the evidence of the plaintiff that Mr Hanlon and Harwood Andrews had nothing to do with her taking of the documents and mobile telephones, and that they had not even known that she intended to do so. The defendant did not lead any evidence to contradict the evidence of the plaintiff on that topic, nor did he lead any evidence whatsoever to indicate any involvement by Hanlon and Harwood Andrews in the alleged theft of the documents and the records. The allegation made by the defendant is serious, and, as such, attracts the principles in Briginshaw v Briginshaw.[12] On the evidence before me, it is entirely baseless. There was not even the faintest scintilla of evidence adduced before me to support the serious allegation made against Mr Hanlon and Harwood Andrews. That allegation is nothing more than a totally unsubstantiated assertion made in a pleading. Indeed, in the course of some submissions to me on 12 December 2008 Mr Johnson expressly acknowledged that Mr Hanlon had no knowledge that the documents were being taken by the plaintiff.[13] Further, he did not address any submissions to me, on this aspect of the counterclaim, in response to Ms Sofroniou's no case submission to me. Self-evidently, Mr Hanlon and Harwood Andrews have no case to answer in respect of that part of the claim.
