The Court of Appeal upheld the disqualification of a law firm due to a conflict of interest, finding an ethical screen insufficient given the transferring lawyer's close working relationship with opposing counsel.
An appeal concerning the disqualification of counsel due to an alleged conflict of interest arising from a lawyer's transfer between law firms.
The lawyer, who had worked extensively on an insurance coverage dispute for the plaintiff, transferred to the defendant's law firm where he would work closely with opposing counsel.
The court addressed whether an ethical screen could adequately protect the former client's confidential information given the intense working relationship between the two lawyers.
The appeal court upheld the disqualification, finding that while the firm had achieved technical compliance with professional guidelines, the spirit of those guidelines was absent and the presumption of inadvertent disclosure could not be rebutted by clear and convincing evidence.
