A legal practitioner who deliberately and persistently fails to attend court proceedings on multiple occasions without renouncing agency, and who disregards clear court instructions including an invitation to show cause why punitive costs should not be awarded, exhibits conduct that is sufficiently improper, disrespectful, and contemptuous to warrant an order for costs de bonis propriis against the practitioner personally. Such conduct, which causes unnecessary postponements, wastes judicial time, and imposes unnecessary costs on parties, demonstrates unreasonable, irresponsible, and grossly reckless behaviour warranting exceptional remedies. A legal practitioner who wishes to cease representing a client must comply with the rules of court regarding renunciation of agency (Order 2 r 6 of the High Court Rules, 1971), and cannot simply abandon a matter by failing to attend without formal renunciation.
