Qatar Investment and Project Development Holding Co & Anor v Phoenix Ancient Art S.A. & Ors
[2023] EWHC 1916 (KB)
A new claim can be added via amendment only if it arises out of the same facts or substantially the same facts as the existing claim (CPR r. 17.4).
CPR r. 17.4
The policy underlying s. 35 and CPR r. 17.4 is to prevent a defendant from investigating matters unrelated to the original claim.
Mulally & Co Ltd v. Martlet Homes Ltd [2022] EWCA Civ 32
A 'cause of action' is a factual situation entitling one person to a remedy against another.
Mulally & Co Ltd v. Martlet Homes Ltd [2022] EWCA Civ 32; Letang v. Cooper [1965] 1 QB 322
Permission to amend was refused for the proposed new Section D(i) (duty to report to PwC Stockholm).
This introduced a new and freestanding duty, requiring significant new factual investigation outside the scope of the original claim, violating the policy of the Limitation Act and CPR r. 17.4.
Permission to amend paragraphs 46 and 50 was granted.
These amendments provided particularisation of existing claims and did not introduce new causes of action. Amendment to paragraph 50 was subject to refinement to remove ambiguity.
