Is an adjudicator's late decision enforceable?

Reaching the decision, prompt communication and valid extensions

The answer depends on the governing adjudication procedure, jurisdiction and facts. Distinguish the deadline for reaching the decision from the obligation to communicate a completed decision promptly.

Quick answer

Secure a valid extension before expiry; if lateness occurs, analyse making, communication and continuation of the appointment separately

The ordinary statutory period is 28 days, calculated from referral under the applicable rules and subject to permitted extension. A decision reached on time but communicated shortly afterwards may be valid where the applicable procedure requires prompt or forthwith delivery. A decision first reached after the deadline is exposed to challenge, but the effect of lateness has not been expressed uniformly in every authority or jurisdiction. Check whether the parties agreed an extension, continued participating, revoked or replaced the adjudicator, suffered material delay, or relied on a different contractual rule.

Section 1

Build the deadline chronology

Record receipt of the referral, the applicable starting rule, original deadline, every agreed or referring-party extension, the date the decision was completed and the date and method of communication.

Section 2

Starting the period

Historic views competed on dispatch and receipt of the referral. Apply the governing Scheme or contractual wording and preserve objective evidence of receipt rather than assuming a rule from a different procedure.

Section 3

Ritchie Brothers

Ritchie Brothers (PWC) Ltd v David Philp (Commercials) Ltd[2005] CSIH 32

The Inner House of the Court of Session held that the Scheme requirement for the adjudicator to reach his decision within the period is mandatory, reversing the more permissive decision at first instance.

Section 4

Barnes and Elliott

Barnes & Elliott Ltd v Taylor Woodrow Holdings Ltd and George Wimpey Southern Ltd[2003] BLR 111

The decision was enforced where it had been made within time and communicated two days later, completion and communication being treated as separate stages.

Section 5

Two-stage analysis

IssueQuestion
Stage 1When was the adjudicator's decision actually completed?
Stage 2When and how was that completed decision communicated?
ExtensionWas a permitted extension agreed before expiry?
AppointmentHad the appointment been revoked or replaced?
ConductDid the parties continue without objection after expiry?
Governing lawWhich court and procedural provisions apply?
Section 6

Hart Investments

Hart Investments Ltd v Fidler[2006] EWHC 2857 (TCC)

On one view, a decision reached after the unextended deadline was a nullity. That proposition should be read as confined to the facts of that decision rather than as a universal result.

Section 7

Dalkia Energy

Dalkia Energy and Technical Services Ltd v Bell Group UK Ltd[2009] EWHC 73 (TCC)

The decision had to be reached within the mandatory period, with a short additional period available for prompt communication after completion.

Section 8

Communication must be prompt

A completed decision should be sent immediately or as soon as the governing procedure requires. Administrative convenience, fee collection or avoidable delay may undermine reliance on a separate communication stage.

Create completion evidence

The adjudicator should retain a dated final document and an auditable dispatch record. A later assertion of earlier completion may be disputed.

Section 9

Extensions

Seek and record any extension before the deadline. State the exact revised date and whether it covers reaching the decision, communication or both. Do not rely on silence or informal ambiguity where written agreement is required.

Section 10

Party response to impending delay

A party should state promptly whether it agrees an extension, reserves a timing objection or seeks a replacement. Strategic silence followed by a later challenge may raise waiver or election arguments, depending on the law and facts.

Section 11

Deadline sequence

1

4

8
