Legal Principles
An adjudicator's power to revise a decision is limited to correcting clerical or typographical errors under the Scheme for Construction Contracts 1998, paragraph 22A(1).
Scheme for Construction Contracts 1998, paragraph 22A(1)
An erroneous exercise of power by an adjudicator does not automatically constitute an excess of jurisdiction; the court focuses on whether the adjudicator purported to exercise a power they did not have.

Courts should be cautious in characterising a mistaken answer to an issue within the scope of the reference as an excess of jurisdiction, given the speedy nature of adjudication.

The doctrine of election prevents a party from inconsistently relying on an adjudicator's decision.

Outcomes
Summary judgment granted to MHL to enforce the original adjudicator's decision of 31st October 2023 for £808,000.
The Revised Decision was not a correction of a clerical error, but a substantive alteration based on further submissions. The adjudicator exceeded his powers under paragraph 22A(1) of the Scheme for Construction Contracts 1998. MHL's actions did not constitute approbating and reprobating the decision.
