“Causation …the court has jurisdiction to make a wasted costs order only where the improper, unreasonable or negligent conduct complained of has caused a waste of costs and only to the extent of such wasted costs. Demonstration of a causal link is essential…. Procedure … The overriding requirements are that any procedure must be fair and that it must be as simple and summary as fairness permits. Fairness requires that any respondent lawyer should be very clearly told what he is said to have done wrong and what is claimed… Hearings should be measured in hours, and not in days or weeks. Judges must not reject a weapon which Parliament has intended to be used for the protection of those injured by the unjustifiable conduct of the other side’s lawyers, but they must be astute to control what threatens to become a new and costly form of satellite litigation. “Show cause”
“50. As a general rule allegations of breach of duty relating to the conduct of the case by a barrister or solicitor with a view to the making of a costs order should be confined strictly to questions which are apt for summary disposal by the court. Failures to appear, conduct which leads to an otherwise avoidable step in the proceedings or the prolongation of a hearing by gross repetition or extreme slowness in the presentation of evidence or argument are typical examples. The factual basis for the exercise of the jurisdiction in such circumstances is likely to be found in facts which are within judicial knowledge because the relevant events took place in court or are facts that can easily be verified. Wasting the time of the court or an abuse of its processes which results in excessive or unnecessary cost to litigants can thus be dealt with summarily on agreed facts or after a brief inquiry if the facts are not all agreed. Scope for the making of a costs order that will compensate as well as penalise is then likely to be found in making an order against the practitioner that will indemnify the opposing litigant against costs incurred as a result of the breach of duty that would otherwise not be recoverable… 53. Their Lordships do not say that the court has no jurisdiction to make a costs order in favour of the client against his own barrister or solicitor. But in cases where an order to that effect is contemplated the court must take great care to confine its attention to the facts which are clearly before it or to facts relating to the conduct of the case that are immediately and easily verifiable.Allegations that may raise questions about duties owed to the client by the barrister or solicitor and the conduct of the case outside the courtroom are unlikely to be of that character.They are likely therefore to fall outside the proper scope of that inquiry. The court must bear in mind that it is not its function, in the exercise of this jurisdiction, to adjudicate on the position as between the client and his barrister or solicitor. 54. …Bearing in mind the extra cost which an investigation of that kind may involve, and the overriding requirement of fairness to those who are at risk of being penalised, the court may well conclude that further investigation under this procedure is not appropriate. This need not be seen as a surrender by the court of its responsibility. The client may have other remedies. A complaint may be made to the Law Society leading to disciplinary sanctions against the barrister or solicitor, or a claim may be made by the client against the solicitor in damages for negligence”
