The Court of Appeal disagreed; the second adjudicator had not decided the same dispute as the first. • In deciding whether or not a dispute is “the same or substantially the same” one does not look at the dispute referred to a second adjudicator in isolation. One must look at the actual decision of the first adjudicator. This determines how much or how little remains for consideration by the second adjudicator. (The literal meaning of paragraph 9 of the Scheme could suggest a broader approach. However the narrower view which focuses on the issues actually decided in the first adjudication, rather than the issues referred to it, was upheld by the Court of Appeal’s earlier decision in Harding v Paice in late 2015.) • The question is one of “fact and degree”. The starting point will be the second adjudicator’s view of whether the dispute referred to him is the same or substantially the same. The court will have “due respect” for the adjudicator’s decision. • The second adjudicator in the present case was asked to determine a different issue. Even though both adjudications involved the same sum of money being claimed and the same parties, the second adjudication involved matters which had not been put before the first adjudicator – namely the fresh letter which amounted to a payment notice. The court highlighted that CBS was not trying to correct the mistakes in its earlier notice, rather it was approaching its claim via a new and different route. Conclusions and implications This decision provides additional Court of Appeal authority for a narrow approach to determining whether a dispute referred to
adjudication is sufficiently different from previous adjudications between the same parties. The Court of Appeal’s suggestion that the subsequent adjudicator’s view as to this issue is the starting point is notable. (It is also ambiguous whether the court’s reference to “the adjudicator’s decision being accorded due respect” meant the previous adjudicator’s award, or the subsequent adjudicator’s view on whether to proceed.) The previous cases referred to by the court would not appear to go this far. They suggest that the previous adjudicator’s award is the starting point for any analysis as to the matters decided in the previous adjudication. Whichever is correct, this reference may be seized upon by parties in the future as supporting an even more limited approach in circumstances where a subsequent adjudicator has accepted jurisdiction, despite similar issues having been decided in a prior adjudication i.e. allowing more adjudications to proceed. In summary: • It is vital to consider the actual decision of the previous adjudicator (not just the dispute referred to him or her). This determines how much or how little remains for consideration by the subsequent adjudicator. • It may be the case that the court should take the subsequent adjudicator’s view as to the question as a starting point and accord it “due respect”. • Getting certificates and payment notices right under construction contracts remains critical. • Adjudication tactics are key.
