“On the issue whether the solicitor is possessed of relevant confidential information: (a) it is in general not sufficient for the client to make a general allegation that the solicitor is in possession of relevant confidential information if this is in issue: some particularity as to the confidential information is required: see Bricheno v Thorp, Jac 300 and Johnson v Marriott (1833) 2 C. & M. 183. But the degree of particularity required must depend upon the facts of the particular case, and in many cases identification of the nature of the matter on which the solicitor was instructed, the length of the period of original retainer and the date of the proposed fresh retainer and the nature of the subject matter for practical purposes will be sufficient to establish the possession by the solicitor of relevant confidential information. (b) it may readily be inferred that confidential information is imparted to members of the firm having conduct of the client’s matter. Such information may, however, be imparted to other members in the course of partnership meetings or social meetings of members of the firm: see In re A Firm of Solicitors[1992] QB 959 , 978C. (c) The court attaches weight to the evidence of the solicitor as to his state of knowledge and whether he received confidential information, in particular where there is no challenge to his integrity and credibility: see Robinson v Mullett (1817) 4 Pr. 353 (solicitor); In re A Solicitor (1987) 131 SJ 1063, per Hoffmann J and Pavel v Sony Corporation,12 April 1995 (barrister). ”
