Arbitration Law in UK Law

It is by now firmly established that more than one national system of law may bear upon an international arbitration. Thus, there is the proper law which regulates the substantive rights and duties of the parties to the contract from which the dispute has arisen. Exceptionally, this may differ from the national law governing the interpretation of the agreement to submit the dispute to arbitration.

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.

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.

There are wider interests at stake, notably the proper functioning of our arbitration system. Since nobody can prevent the losing party in an arbitration from applying for leave to appeal even in the most unmeritorious cases, it is of supreme importance to the proper working of our arbitration system that there must be an effective procedure to ensure that applications for leave are promptly made.
