Summary
Applications to amend are governed by a single balancing exercise. The court must decide whether the injustice to the applicant if permission is refused outweighs the injustice to the opposing party and other litigants if permission is granted.
Relevant factors include the timing, clarity and necessity of the amendment, the explanation for delay, the work already undertaken, prejudice to the other party, the risk to the trial date, and the requirements of the overriding objective. A late amendment may be allowed where it advances an intelligible and apparently credible case and can be addressed without disproportionate prejudice. Statements of case should plead material facts and identify the issues, rather than evidence, argument, motive or rhetoric.
Factual background
UBB Waste (Essex) Limited applied shortly before a 20-day trial to re-amend its Defence and Counterclaim in litigation concerning a long-term private finance contract for a waste treatment facility.
The proposed amendments included additional allegations of breach of implied duties of good faith, further contractual allegations arising from later events, alternative financial claims and proposed declarations. Essex County Council opposed many amendments on grounds including delay, prejudice, prolixity and lack of necessity.
The central issues were whether the amendments were sufficiently intelligible and credible, whether they were necessary to advance UBB’s case, and where the balance of injustice lay in the circumstances of the impending trial.
Held
- Outcome. The application was allowed in part and refused in part. The court allowed amendments which advanced UBB’s real case, including additional allegations that already pleaded breaches also involved alleged failures to act in good faith. It disallowed unnecessary, prolix or immaterial amendments.
- Applicable approach. The court formulated one governing rule: parties should be allowed to amend to bring forward intelligible and apparently credible claims or defences where the balance of injustice favours permission. The court must consider the overriding objective, compliance with procedural obligations, efficient and proportionate litigation, and the wider interests of other court users.
- Lateness and prejudice. Lateness is relative. The court considered when the amendment could have been made, the quality of the explanation, duplication of work, the need to revisit disclosure or evidence, and whether the trial date was threatened. The fact that the trial date was not endangered was important but not decisive. Essex was still entitled to prepare its own case rather than being diverted by UBB’s delay.
- Nature of pleadings. Statements of case should identify the issues and plead material facts. Evidence, document commentary, motive, rhetoric and unnecessary particulars generally belong in cross-examination or submissions, not pleadings. The court therefore refused amendments directed to those matters.
- Good faith. The application was not an appropriate vehicle for finally deciding the existence, scope or breach of alleged contractual duties of good faith. Those issues were not hopeless and were already raised for determination at trial. The additional allegations were permitted where they introduced no new implied term and largely concerned facts already pleaded and disclosed.
- Other amendments. Amendments concerning later planning events, alternative contractual outcomes, Relief Events and alternative financial relief were allowed where the issues were sufficiently particularised and could be met without adjournment. Proposed declarations that merely sought findings of fact, rather than declarations of contractual rights, were refused.
