“85. The objective which underlies the Act and the statutory scheme requires the courts to respect and enforce the adjudicator's decision unless it is plain that the question which he has decided was not the question referred to him or the manner in which he has gone about his task is obviously unfair. It should be only in rare circumstances that the courts will interfere with the decision of an adjudicator. The courts should give no encouragement to the approach adopted by DML in the present case; which (contrary to DML's outline submissions, to which we have referred in paragraph 66 of this judgment) may, indeed, aptly be described as ‘simply scrabbling around to find some argument, however tenuous, to resist payment’. ” 86. It is only too easy in a complex case for a party who is dissatisfied with the decision of an adjudicator to comb through the adjudicator's reasons and identify points upon which to present a challenge under the labels ‘excess of jurisdiction’ or ‘breach of natural justice’. It must be kept in mind that the majority of adjudicators are not chosen for their expertise as lawyers. Their skills are as likely (if not more likely) to lie in other disciplines. The task of the adjudicator is not to act as arbitrator or judge. The time constraints within which he is expected to operate are proof of that. The task of the adjudicator is to find an interim solution which meets the needs of the case...The need to have the ‘right’ answer has been subordinated to the need to have an answer quickly. The scheme was not enacted in order to provide definitive answers to complex questions... 87. In short, in the overwhelming majority of cases, the proper course for the party who is unsuccessful in an adjudication under the scheme must be to pay the amount that he has been ordered to pay by the adjudicator. If he does not accept the adjudicator's decision as correct (whether on the facts or in law), he can take legal or arbitration proceedings in order to establish the true position. To seek to challenge the adjudicator's decision on the ground that he has exceeded his jurisdiction or breached the rules of natural justice (save in the plainest cases) is likely to lead to a substantial waste of time and expense – as, we suspect, the costs incurred in the present case will demonstrate only too clearly.”
“28... If costs are awarded on an indemnity basis, in many cases there will be some implicit expression of disapproval of the way in which the litigation has been conducted, But I do not think that this will necessarily be so in every case. What is, however, relevant to the present appeal is that litigation can readily be conducted in a way which is unreasonable and which justifies an award of costs on an indemnity basis, where the conduct could not properly be regarded as lacking moral probity or deserving moral condemnation.”
“I do not believe that unnecessary or unreasonable pursuit of litigation must involve an ulterior purpose in order to trigger the court's discretion to order indemnity costs. I consider that to maintain a claim that you know, or ought to know, is doomed to fail on the facts and on the law, is conduct that is so unreasonable as to justify an order for indemnity costs.”
