Pleadings containing allegations that are scandalous, vexatious or irrelevant must be struck out under Rule 23(2) of the Uniform Rules (applicable to the Land Claims Court via Rule 28(2)) where the opposite party will be prejudiced if the matter is not struck out. Allegations are scandalous if they contain unnecessary imputations of misconduct or bad faith against the opposite party or their legal representatives that are not required to establish the pleader's case. Legal practitioners as officers of the court owe duties of professionalism and courtesy to the court and to colleagues. Where legal practitioners include scandalous and gratuitous attacks on colleagues in pleadings without justification, particularly where the offensive material is not necessary to establish the client's defence, a costs order de bonis propriis is appropriate as a mark of the court's displeasure. Such conduct, when it involves serious accusations of breaching ethical duties, misleading courts, and subverting justice, impacts not only on the dignity of the individuals concerned but on the dignity of the administration of justice itself. A costs order de bonis propriis will be granted against legal practitioners where their conduct amounts to improper conduct, is motivated by malice, involves negligence in a serious degree, or is designed to harass the other side or obstruct justice, particularly where the practitioner reaffirms their support for the offensive material when challenged.
