Adjudication in UK Law

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". 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.

Similarly, the claiming party is not limited to the arguments, contentions and evidence put forward by it before the dispute crystallised. The adjudicator or arbitrator must then resolve the referred dispute, which is essentially the challenged claim or assertion but can consider any argument, evidence or other material for or against the disputed claim or assertion in resolving that dispute.

In a number of the authorities which I have cited above the point has been made that each case must turn on its own facts. Whilst I respectfully agree with that, it does seem to me that there are a number of clear principles which should always govern the exercise of the court's discretion when it is considering a stay of execution in adjudication enforcement proceedings. Those principles can be set out as follows:

The fact that adjudication under the Scheme and adjudication under a JCT Prime Cost Contract would be similar procedures does not overcome the twin difficulties that Mr Morris was appointed under the Scheme, and that a sufficiently secure identification of the contractual terms was intrinsically necessary to the proper performance of his adjudication task.

A particular dispute, somewhat like a snowball rolling downhill gathering snow as it goes, may attract more issues and nuances as time goes on; the typical example in a construction contract is the ever increasing dispute about what is due to the contractor as each monthly valuation and certificate is issued; a later certificate may accept amounts in issue previously not certified but then reject some more items of work.

If an adjudicator declines to consider evidence which, on his analysis of the facts or the law, is irrelevant, that is neither (a) a breach of the rules of natural justice nor (b) a failure to consider relevant material which undermines his decision on Wednesbury grounds or for breach of paragraph 17 of the Scheme. If the adjudicator's analysis of the facts or the law was erroneous, it may follow that he ought to have considered the evidence in question.

Precisely the same effect is achieved by those contracts which incorporate paragraph 9.2 of the Scheme for Construction Contracts. That provides that an adjudicator must resign where the dispute is the same or substantially the same as one which has previously been referred to adjudication and a decision has been taken in that earlier adjudication. As Dyson LJ observed in Quietfield Ltd v. Vascroft Construction Ltd. [2007] BLR 67 at paragraph 45
