The Scope of Collateral Warranties and Net Contribution Clauses

The recent Technology and Construction Court (TCC) decision in BNP Paribas Depository Services Ltd v Briggs & Forrester Engineering Services Ltd [2024] EWHC 2903 (TCC) provides important clarification on the interpretation and application of collateral warranties and, crucially, net contribution clauses within those warranties. This case offers valuable insights for developers, contractors, subcontractors, and funders involved in construction projects.

Background of the Case

The case involved a claim by BNP Paribas Depository Services Ltd (BNP), the funder of a development project, against Briggs & Forrester Engineering Services Ltd (Briggs), a subcontractor who had provided mechanical and electrical (M&E) services. BNP brought the claim under a collateral warranty granted by Briggs, alleging defects in the M&E works. A key aspect of the dispute centred on the interpretation and effect of a net contribution clause within the warranty.

Key Features of the Collateral Warranty

The collateral warranty between BNP and Briggs contained standard provisions, but the focus of the dispute was on the net contribution clause. A typical net contribution clause aims to limit a party’s liability to the proportion of the loss for which they are justly responsible, taking into account the contributions of other parties who may also be liable for the same loss. 

The Central Issue: Interpretation of the Net Contribution Clause

The primary issue before the court was the proper interpretation and application of the net contribution clause in the collateral warranty. BNP argued for a narrow interpretation, contending that the clause should only apply where there were other concurrent wrongdoers who were actually pursued and held liable. Briggs, conversely, argued for a broader interpretation, claiming that the clause should apply even if other potential wrongdoers were not pursued or were insolvent.

The Court’s Decision

The TCC sided with Briggs, adopting a broader interpretation of the net contribution clause. The court held that the clause operated to limit Briggs’ liability to its fair share of the overall loss, regardless of whether other potentially liable parties had been joined in the proceedings or were capable of contributing.

Key Principles and Takeaways

Several key principles emerge from this judgment:

  • Broad Interpretation of Net Contribution Clauses: The decision reinforces the court’s tendency to adopt a commercially sensible and broad interpretation of net contribution clauses. The aim is to achieve a fair apportionment of liability based on the respective responsibilities of the parties involved.
  • Focus on Proportional Liability: The court emphasized that net contribution clauses are designed to ensure that a party is only liable for its proportionate share of the loss, not the entire loss simply because it is the party being sued.
  • Importance of Clear Drafting: While the court adopted a broad interpretation in this case, the importance of clear and unambiguous drafting of net contribution clauses cannot be overstated. Parties should ensure that the clause clearly reflects their intentions regarding the scope of limitation.
  • Impact on Litigation Strategy: The decision has implications for litigation strategy, as claimants may need to consider pursuing multiple parties to ensure full recovery of their losses, rather than relying on one party to bear the entire burden.

Practical Implications for the Construction Industry

This case has important practical implications for various stakeholders in the construction industry:

  • For Funders: Funders should be aware of the potential limitations imposed by net contribution clauses in collateral warranties. They should carefully review these clauses and consider the implications for their recovery strategy in the event of defects.
  • For Contractors and Subcontractors: Contractors and subcontractors should ensure that their collateral warranties include appropriately drafted net contribution clauses to limit their liability to their fair share of the loss.
  • For Developers: Developers need to be aware of the potential limitations on recovery imposed by net contribution clauses when pursuing claims under collateral warranties.
  • Impact on Insurance: The decision may also have implications for professional indemnity insurance, as insurers will need to consider the impact of net contribution clauses on their potential liabilities.

Distinguishing from Previous Case Law

The court distinguished this case from previous cases where narrower interpretations of net contribution clauses had been adopted, emphasizing the specific wording of the clause in question and the overall commercial context.

Conclusion

BNP Paribas Depository Services Ltd v Briggs & Forrester Engineering Services Ltd provides valuable clarification on the interpretation and application of net contribution clauses in collateral warranties. The decision reinforces the principle of proportionate liability and underscores the importance of clear contractual drafting. This case is essential reading for all parties involved in construction projects and highlights the need for careful consideration of the implications of collateral warranties and their associated limitations on liability. It serves as a reminder that the courts are likely to interpret net contribution clauses in a way that promotes a fair and proportionate allocation of responsibility for defects.
