A solicitor moving from a firm acting on one side of a dispute to the firm on the other side must be able to show that no conflict of interest would arise. The court should intervene unless it is satisfied that there is no risk of disclosure. It goes without saying that the risk must be a real one, and not merely fanciful or theoretical. But it need not be substantial. Lightman J stated that in a ‘previous relationship’ case, in the ordinary course a court will grant an injunction restraining the solicitor acting.
Lightman J said: ‘The law regulating the freedom of a solicitor who, or whose firm, has at one time acted for a client subsequently to act against that client reflects the need to balance two public interests. First there is the interest in the entitlement of that client to the fullest confidence in the solicitor whom he instructs and for this purpose that there shall be no risk or perception of a risk that confidential information relating to the client or his affairs acquired by the solicitor will be disclosed to anyone else . . Second there is the interest in the freedom of the solicitor to obtain instructions from any member of the public, and of all members of the public to instruct such solicitor, in all cases where there is no real need for constraint; there must be good and sufficient reason to deprive the client of the solicitor or the solicitor of the client of his choice.’
