The law concerning judicial disqualification of lawyers acting against former clients currently depends on whether there is a risk of misuse of the former client’s confidential information. The House of Lords’ decision in Prince Jefri Bolkiah v KPMG held that fiduciary obligations do not survive the termination of the retainer.

This article argues that this basis exists as a matter of fiduciary doctrine.
