Dumford Trading Ag v Oao Atlantrybflot

Summary judgment is inappropriate where a defendant raises a real issue as to the claimant’s title to sue and the effect of an assignment has not been properly analysed.

The doctrine of misnomer is one of construction. Where two distinct entities exist, the court must identify from the document which entity was intended. Where only one entity can fit, surrounding evidence may identify an inaccurate description. The boundaries between misnomer, matrix or extrinsic evidence, and rectification require caution. Evidence should not be used summarily to substitute one contracting party for another. An estoppel-by-convention issue is likewise generally unsuitable for summary disposal where material facts remain disputed.

Dumford lent money to Shelley Marketing LLC, whose indebtedness was guaranteed in documents naming ZAO Atalantribflot. The guarantees contained English jurisdiction and governing-law clauses. OAO Atlantrybflot, a separate Russian company and ZAO’s former parent, denied being the guarantor and challenged both jurisdiction and Dumford’s title to sue following an assignment.

The Commercial Court, presided over by His Honour Judge Chambers QC, treated the contractual reference to ZAO’s registered office as creating ambiguity, considered external documentary evidence, and entered summary judgment for Dumford under Part 24: [2004] EWHC 1099 (Comm). OAO appealed. The central issues were assignment, misnomer, construction of the guarantor’s identity, use of extrinsic evidence, and estoppel by convention.

Appeal allowed. Rix LJ gave the leading judgment, with Brooke and Jonathan Parker LJJ agreeing. The court quashed paragraph 1 of the order, which gave Dumford summary judgment under Part 24, and paragraphs 4–7, which contained consequential costs orders. Paragraph 3, dismissing OAO’s own Part 24 application, was unchallenged and stood. The effect of the appeal on paragraph 2, concerning OAO’s jurisdictional challenge, required further argument or remission.

1. Title to sue. Clause 16.3, if it restricted assignment to a bank or financial institution, did so only implicitly, given clause 16.1 and guarantee clause 9.1. Even if the assignment breached that restriction, it was not clear that the assignment was void and wholly ineffective at the assignor’s instance. The fact that an assignment might be invalid against a debtor did not necessarily mean that the assignor retained title to sue, particularly where the assignee had acted upon it. The unresolved issue created a real issue requiring a defence.
2. Misnomer. Misnomer is a doctrine of construction. The relevant question is what a reasonable reader would understand the document to mean. Where two distinct entities exist, the document itself must indicate which was intended. Where only one possible entity exists, extrinsic evidence may identify an inaccurately described party. The existence of both ZAO and OAO, together with the inadequately explained alleged typographical error, meant that summary judgment could not safely be granted on the basis of mere misnomer. The ultimate answer was left open.
3. Construction and extrinsic evidence. The written document remained central to identifying the contracting party. There was a danger that external evidence was being used to create an ambiguity or substitute OAO for ZAO, a function more closely associated with rectification. The interaction between misnomer, matrix evidence, extrinsic evidence and rectification had not been sufficiently explored for a Part 24 application.
4. Estoppel by convention. The issue was essentially factual and could not be dealt with summarily.

• Court of Appeal (Civil Division): Appeal allowed. Summary judgment and consequential costs orders quashed; further directions were given concerning jurisdiction, costs and any renewed Part 24 application.
• Commercial Court: His Honour Judge Chambers QC granted Dumford summary judgment and dismissed OAO’s jurisdictional challenge: [2004] EWHC 1099 (Comm).
