Mersey Docks Property Holdings Ltd & Ors v Birse Construction Lrd & 4 Orsy

For limitation purposes, a proposed amendment raises a new cause of action where it introduces a distinct factual situation entitling the claimant to a remedy. The comparison must focus on the essential, material facts required to prove the existing and proposed claims, excluding particulars and non-essential evidence. Under CPR Part 17.4(2), the relevant facts may be those already in issue in the proceedings, including claims against other parties, rather than only claims against the defendant concerned. That wider construction does not remove the court’s discretion to control amendments and case management. The court must ensure that the amended pleading accurately identifies the parties, facts and causation, while preventing injustice and disproportionate procedural complexity.

The claimants sought permission to amend their Particulars of Claim arising from a substantial fire at a cold storage and distribution centre. The defendants included the head contractor, architects, engineers and other consultants. Several defendants argued that proposed allegations introduced new causes of action after expiry of the limitation period and therefore failed the requirements of section 35 of the Limitation Act 1980 and CPR Part 17.4(2).

The central issues were whether the amendments introduced new causes of action, whether those causes arose from the same or substantially the same facts as claims already made in the proceedings, and how the court should exercise its case-management discretion.

1. New cause of action. A cause of action is a factual situation which entitles one person to obtain a remedy against another. Whether an amendment introduces a new cause depends on the nature and extent of the duty, breach and damage relied upon. The fact that allegations concern the same building does not necessarily mean that they form one cause of action.
2. Material facts. The court must compare the pleadings before and after amendment and identify the essential facts requiring proof. Non-essential facts, particulars and mere instances are excluded. A res judicata analysis may assist as a cross-check, but is not decisive.
3. Scope of CPR Part 17.4(2). The phrase referring to facts already in issue in the proceedings was construed broadly. A new claim may arise from substantially the same facts as claims made against other parties. The proposed claims concerning collateral warranties, design, workmanship, inspection and warnings therefore satisfied the statutory factual connection requirement, even where some allegations might amount to new causes of action.
4. Discretion and case management. Satisfaction of the limitation test does not require permission automatically. The court retains discretion under the CPR to manage the litigation and give effect to the overriding objective. The parties agreed a procedure involving requests for further information, a comprehensive replacement pleading and subsequent responses. That course was appropriate because the fire had destroyed documents and the case required accurate pleading of parties, facts and causation.
5. The court did not finally determine all discretionary objections to individual amendments. The parties were to be heard on the precise consequential orders.
