Case details
Summary
A claim form amended without permission under CPR 17.1(1) before service may be validly served without first being filed with the court, where the amendments are made to the already sealed claim form. The rules contain no sufficiently clear basis for implying a mandatory pre-service filing requirement, particularly where non-compliance would invalidate service and deprive the court of jurisdiction. The position differs where the claimant prepares a new, unsealed amended claim form: that document must be filed and sealed before it can be served as a claim form. Filing may nevertheless be required later under CPR 6.17(2) where the obligation to file a certificate of service applies.
Factual background
The claimant brought proceedings against the defendants. The original claim form was issued and sealed on 5 June 2024. Before service, the claimant amended the sealed claim form in manuscript under CPR 17.1(1) and posted it to the defendants’ solicitors on 2 October 2024. The documents were deemed served on 4 October, within the four-month period under CPR 7.5(1).
The Senior Master held that service was valid and dismissed the defendants’ jurisdiction application. The defendants appealed, arguing that the amended claim form had to be filed and accepted by the court before service. The central issue was whether such a pre-service filing requirement existed under the CPR and the applicable Electronic Working practice direction.
Held
- Appeal dismissed. The amended claim form was validly served within four months of issue.
- A claim form must be sealed before it is a claim form for CPR purposes and before it can be validly served. The seal identifies the date of issue and starts the period for service. The court applied the principles in Walton v Pickerings Solicitors and anor [2023] EWCA Civ 602 and Ideal Shopping Direct Ltd v Mastercard Inc [2022] EWCA Civ 14.
- There was no express provision in Part 17 or its Practice Direction requiring a claim form amended without permission under CPR 17.1(1), by altering the already sealed claim form, to be filed before service. The reference to a court copy in PD 17 para 2.1 did not supply a sufficient basis for implying such a duty.
- The consequences of the proposed implied requirement would be serious, including invalid service and loss of jurisdiction. Procedural requirements carrying such consequences should be clearly expressed and accessible. Good practice to file an amended statement of case did not amount to a mandatory pre-service condition.
- The court distinguished the situation where amendments are placed on a new, unsealed claim form. Following Ideal Shopping Direct Ltd v Mastercard Inc [2022] EWCA Civ 14, that document must be filed and sealed before service. The court also rejected reliance on Hills Contractors and Construction Ltd v Struth [2014] 1 WLR 1 and considered Cant v Hertz Corporation [2015] EWHC 2617 (Ch) unhelpful to the defendants’ argument.
- Where applicable, CPR 6.17(2) required the amended claim form to be filed with the certificate of service if it had not already been filed. That provision did not create a general pre-service filing requirement.
- The court endorsed the Senior Master’s view that the Civil Procedure Rules Committee should consider clarifying the position. Consequential matters were left for written submissions.
