Introduction

The case of Dragados (UK) Ltd (the pursuer) versus DC EIFEKET Aggregates AS (the defender) was adjudicated in the Scottish Court of Session on November 16, 2021. This dispute centered around the quality of armourstone supplied under a Supply Contract Agreement for the Aberdeen Harbour Expansion Project. The disagreement arose from the categorization of the stone—category A (higher quality) versus category B—supplied by the defender. The pursuer alleged that the contract necessitated category A stone, while the defender contended it supplied category B based on its understanding of the contractual terms.

Summary of the Judgment

The Scottish Court of Session, presided over by Lord Braid, examined the contract's terms and the legitimacy of considering pre-contractual negotiations in interpreting these terms. The court concluded that the contract's express terms, particularly the "entire agreement" clause, barred any reliance on prior negotiations or representations. Consequently, the defender's arguments attempting to introduce pre-contractual discussions were deemed inadmissible. Furthermore, the defender's "personal bar" claim, suggesting that the pursuer was precluded from asserting entitlement to category A stone due to prior acceptance of category B, was dismissed as it lacked proper pleading and legal foundation. The court upheld the pursuer's stance, enforcing the contract's requirement for category A stone.

Analysis

Precedents Cited

The judgment heavily relied on established case law to reinforce the exclusionary rule in contract interpretation. Key precedents include:

• Luminar Lava Ignite Ltd v MAMA Group Plc [2010] SC 310: Affirmed that pre-contractual statements or negotiations cannot be used to interpret contract terms, emphasizing the primacy of the final written agreement.
• Bank of Scotland v Dunedin Property Investment Company Limited [1998] SC 657: Highlighted that negotiation-related evidence is inadmissible if it merely attempts to clarify or "put a gloss" on the contract.
• Paterson v Angelline (Scotland) Ltd [2021] CSOH 101: Discussed the boundaries of admissible evidence in contract interpretation, though distinguished from the case at hand due to differing factual contexts.
• William Grant & Sons Ltd v Glen Catrine Bonded Warehouse Ltd [2001] SC 901: Served as a foundation for the modern understanding of acquiescence within the personal bar doctrine.

These cases collectively reinforce the principle that the written contract stands as the definitive record of the parties' agreement, excluding prior or contemporaneous negotiations from influencing its interpretation unless they pertain to the factual background necessary to understand the contract's purpose.

Legal Reasoning

The court's legal reasoning pivoted on the interpretation of the contract's "entire agreement" clause (Condition 12.4), which explicitly stated that the contract supersedes all prior representations or agreements. This clause is pivotal in excluding any attempt by the defender to introduce pre-contractual negotiations into the contractual interpretation. Additionally, the defender's personal bar argument failed due to the lack of a substantive plea and failure to establish a representation that induced reliance to the detriment of the pursuer.

The court meticulously dissected the defender's averments in answers 3.1 and 3.2, categorizing them as irrelevant under the exclusionary rule since they sought to interpret the contract based on mutual understandings rather than the objective terms. Furthermore, the personal bar claim was undermined as the defender did not appropriately plead the necessary elements—representation, reliance, and prejudice—as outlined in Ben Cleuch Estates Ltd v Scottish Enterprise [2008] SC 252.

Impact

This judgment reinforces the sanctity of written contracts, particularly the "entire agreement" clauses, in limiting the scope of contract interpretation to the document's express terms. It serves as a cautionary tale for parties attempting to rely on verbal or informal negotiations post-contract signing to alter or interpret contractual obligations. Additionally, the dismissal of the personal bar argument underscores the necessity for defendants to substantiate such claims with proper pleadings and factual evidence.

For practitioners, this case emphasizes the importance of meticulous contract drafting and the inclusion of comprehensive clauses that preclude the use of extrinsic evidence in disputes. It also highlights the judiciary's current stance on maintaining contractual integrity over subjective interpretations or alleged mutual understandings that are not encapsulated within the written agreement.
