Costain Ltd v. Strathclyde Builders Ltd

Factual and Procedural Background

This opinion addresses procedural principles governing adjudications under a contract, specifically focusing on the procedural fairness owed by an adjudicator within the constraints of strict time limits. The context involves the application of conditions from the Scottish Building Contract, particularly condition 41A, which sets out the adjudicator’s powers and procedural requirements. The opinion examines how these procedural rules and the principles of natural justice apply to the adjudication process.

Legal Issues Presented

1. What procedural fairness is required of an adjudicator given the strict time limits and informal nature of adjudication?
2. Is it sufficient to show a breach of natural justice principles resulting in a possibility of injustice, or must actual injustice be demonstrated?
3. Must any breach of natural justice be substantial and relevant to affect the adjudicator’s decision?
4. How should an adjudicator’s use of own knowledge, information, and advice from third parties be treated in terms of procedural fairness?

Arguments of the Parties

The opinion does not contain a detailed account of the parties' legal arguments.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
Black v John Williams & Co (Wishaw)	Illustrates that a breach of natural justice may be disregarded if the decision favors the complaining party, emphasizing relevance and materiality of breach.	The court used this precedent to explain that only substantial and relevant breaches of natural justice affect the adjudication outcome, and trivial breaches (de minimis) should be ignored.

Court's Reasoning and Analysis

The court emphasized that adjudication procedures are governed primarily by the adjudicator’s control, within the overriding principle of fairness and any express contractual provisions. Due to strict time constraints, the procedure is designed to be simple and informal, requiring only that each party be given an opportunity to comment at relevant stages.

The court noted that if one party submits written contentions, the other party must be given an opportunity to respond, including on any new material introduced. The adjudicator may use personal knowledge or experience to assess submissions without necessarily seeking further comment, unless new factual or legal propositions arise, in which case parties should be given a chance to comment, time permitting.

The adjudicator’s powers to require additional information, tests, or advice from third parties also require that any new matters be disclosed to parties for comment, again within tight time limits.

The court found no distinction between factual and legal information or advice for procedural fairness purposes, recognizing that adjudicators typically rely on others for legal advice.

Regarding natural justice, the court held that a breach must be substantial and relevant to the decision to invalidate it. Minor or irrelevant breaches should be disregarded. The adjudicator’s procedural control means that lack of formalities or deviation from court-like procedures is not a breach unless it denies a fair opportunity to present a case.

Holding and Implications

The court’s final decision is that procedural fairness in adjudication requires only that parties be given a fair opportunity to comment on relevant matters within strict time limits, and that breaches of natural justice must be substantial and material to affect the outcome.

This decision reinforces the informal and time-sensitive nature of adjudication and confirms that procedural irregularities that do not cause substantive unfairness or prejudice will not invalidate an adjudicator’s decision. No new precedent was established beyond clarifying the application of natural justice principles in the adjudication context.
