Network Rail Infrastructure Ltd v ABC Electrification Ltd

In construing a contractual payment provision, the natural and ordinary meaning of default was a failure to comply with a contractual obligation. The court would not imply requirements that the failure be wilful, deliberate, serious, significant or material where the contract contained no such words. Clear language was not displaced by commercial common sense, the target-cost structure, alleged redundancy or the consequences of the bargain. A contractual heading expressly excluded from consideration could not guide the construction of another clause. Declaratory relief was appropriate where resolving the contractual interpretation issue served a useful purpose, even though further factual disputes remained.

Network Rail sought declarations under Part 8 concerning the meaning of Disallowed Cost in clause 1(1)(j)(iii) of a contract incorporating the ICE Conditions subject to NR12 Amendments. The provision referred to costs due to default by the contractor in complying with contractual obligations.

ABC argued that default had a narrower meaning, requiring a wilful and deliberate, or at least serious and material, failure. The central issues were the proper construction of the provision and whether declaratory relief should be granted despite the need for later factual determination of particular deductions.

The court granted the declarations sought.

1. Construction of “default”. Applying the principles in Rainy Sky SA v Kookmin Bank [2011] UKSC 50, Arnold v Britton [2015] UKSC 36 and Wood v Capita Insurance Services Ltd [2017] UKSC 24, the natural and ordinary meaning of “default” in clause 1(1)(j)(iii) was any failure by ABC to comply with its contractual obligations. The clause therefore included costs caused by non-compliance, without requiring proof of a particular state of mind.
2. The court rejected the proposed qualifications of wilfulness, deliberateness, seriousness, significance, materiality or persistence. Such qualifications would require adding words to the contract and would make the cost mechanism uncertain and potentially unworkable.
3. Clause 65 did not narrow the meaning of “default”. Its heading was expressly excluded from consideration by clause 1(3), and the operative termination provisions did not establish that the payment provision was confined to defaults capable of justifying termination. The reasoning in Gregory Projects (Halifax) Ltd v Tenpin (Halifax) Ltd [2009] EWHC 2639 and Rathbone Brothers Plc v Novae Corporate Underwriting [2014] EWCA 1464 supported that conclusion.
4. The alleged overlap with other limbs of the definition of Disallowed Cost did not justify an unnatural construction. Redundancy was insufficient to displace clear language, particularly in a standard-form contract, applying Beaufort Developments v Gilbert Ash [1999] 1 AC 266, Mutual Energy v Starr Underwriting Agents [2016] EWHC 590 (TCC) and Spire Healthcare v Royal & Sun Alliance Insurance [2016] EWHC 3278.
5. The fact that the contract was a target-cost contract, and the possibility that the interpretation might operate harshly, did not alter the result. Commercial common sense could not be invoked retrospectively to contradict unambiguous language.
6. The discretion to grant a declaration was exercised in accordance with the factors identified in FSA v Rourke [2002] CP Rep 14. The declaration served a useful purpose because it resolved the threshold contractual issue underlying a proposed deduction exceeding £13 million, even though the application of the provision to particular costs might require further adjudication or factual determination.
