Angeliki Frangou v Ioannis (John) Frangos

A party who relies on a legal characterisation of a contractual provision, and on legal consequences flowing from that characterisation, must plead the case sufficiently in advance of trial. A pure construction argument may be advanced within an existing pleaded denial where it does not enlarge the issues. Late amendments require a satisfactory explanation, and the court must weigh procedural and substantive prejudice, the strength of the proposed case, pleading adequacy and trial disruption. A change of counsel is not, without more, a sufficient explanation for delay. Where a late amendment would compromise fair preparation and due process, permission should be refused.

The claimant sought payment of US$11,866,844 under clause 5 of an agreement concerning the financing and ownership of a vessel. The defendant denied liability and amended his defence shortly before trial. In written opening submissions he advanced, for the first time, a proposed characterisation of clause 5 as a contract of suretyship, with consequences concerning alteration of the principal obligation. He also relied on a construction argument that the payment obligation did not extend beyond the original financing period. The issues were whether those arguments were admissible on the existing pleadings and, if necessary, whether permission should be given to amend.

1. The proposed Guarantee Analysis was not admissible on the existing pleadings. A defendant denying contractual liability on the basis that the provision is a contract of suretyship, and that specified circumstances discharge or limit liability, must plead both the legal characterisation and its consequences. That characterisation is a substantive positive case, not merely a point of construction. It could affect the trial’s focus and engage formalities governing guarantees and their variation. The requirement to state the reasons for denial under CPR 16.5(1)(a) and (2)(a), together with the Commercial Court pleading requirements, supported that conclusion (paras [18]-[21]).

2. The Duration Analysis was admissible without amendment. It was a pure question of construction of clause 5 in its contractual and commercial matrix. It fell within the pleaded denial that the sale was not one contemplated by, or falling within, clause 5 and did not expand the parameters of the defence (paras [22]-[25]).

3. The court applied the factors identified in Ferand Business Corporation & others v Maritime Investments Holdings Limited & another [2020] EWHC 2665 (Comm), including the strength of the proposed case, the explanation for delay, prejudice, pleading adequacy and the effect on trial preparation. A very late amendment unsupported by a good explanation is likely to be refused, particularly where it causes prejudice (paras [13]-[16]).

4. Permission to introduce the Guarantee Analysis was refused. The defendant had not explained why the case was not pleaded earlier, including when new counsel amended the defence one week before trial. The timing caused disruption and deprived the claimant of a fair opportunity to investigate disclosure and respond to the proposed case. The defendant suffered no comparable prejudice because his existing pleaded defences engaged the same factual narrative and could support construction arguments concerning the payment obligation. The amendment application was dismissed (paras [26]-[33]).
