SKAT’s 2018 negligent misrepresentation claim against broker EDFM failed under the Revenue Rule. SKAT later sued EDFM for fraud. The Supreme Court held that no issue estoppel barred the fraud claim, because issue estoppel is narrowly confined to the immediate foundation of the earlier decision.
Background
SKAT, the Danish Customs and Tax Administration, paid refunds of dividend withholding tax between August 2012 and July 2015 to applicants, including tax-exempt US and Canadian pension plans. Those applications were supported by tax vouchers. EDFM, a financial brokerage business, issued 420 such vouchers to its clients.
The 2018 Proceedings
In 2018 SKAT sued 114 defendants in the Commercial Court. Its case against EDFM, which was designated a “Non-Fraud Defendant”, was confined to two matters:

- negligent misrepresentation in the 420 vouchers; and
- restitution of the fees EDFM had received.
As to 80 “Annex E” vouchers, SKAT alleged that the clients had not received the dividends, or suffered the withholding, stated in the vouchers. As to the remaining 340 vouchers, SKAT alleged that EDFM, rather than the Refund Applicants, was the beneficial owner of any shares or dividends.
Andrew Baker J ordered a preliminary trial of whether any of SKAT’s claims, “as alleged”, were inadmissible under the rule that English courts will not enforce, directly or indirectly, a foreign revenue law (the “Revenue Rule”). He held that all of SKAT’s claims were inadmissible.
Against EDFM, SKAT appealed only on the ground based on the Brussels Recast Regulation, and that appeal failed. It did not pursue the ground that the Annex E claims fell outside the Revenue Rule. Against other defendants, SKAT succeeded in the Court of Appeal and in the Supreme Court ([2023] UKSC 40). Those courts held that claims to recover sums of which SKAT had been defrauded fell outside the Revenue Rule.
The 2022 Proceedings
In December 2022 SKAT brought a new claim against EDFM. It alleged that EDFM knowingly prepared fraudulent tax vouchers in order to induce refunds. The claim covered 286 vouchers:
- the 80 Annex E vouchers;
- 201 other vouchers from the original 420; and
- five new vouchers.
Bright J rejected EDFM’s arguments based on abuse of process and issue estoppel.
The Court of Appeal agreed that there was no abuse of process but held, by a majority, that issue estoppel barred the entire claim. Newey and Popplewell LJJ identified the estopping issue as being that “private law claims to recover [withholding tax] refunds paid out by SKAT based on applications conveying misinformation amount to enforcement of a foreign revenue law”.
Nugee LJ considered that formulation to be “a general proposition of law untethered to any particular facts”. He would instead have confined the estoppel to claims based on the 420 vouchers, which would have excluded the five new vouchers.
The issues
SKAT appealed on three grounds:
- An issue estoppel cannot arise from a prior court’s formulation of legal principle or legal reasoning, as opposed to its application of that reasoning to the facts in issue.
- The issue found by the Court of Appeal was not necessary for, or fundamental to, the 2018 decision. It went beyond the facts pleaded, and New Brunswick Railway shows that a non-traversable issue cannot found an estoppel.
- In the alternative, the “special circumstances” exception recognised in Arnold v National Westminster Bank plc applied. Permission on this ground was granted de bene esse.
The parties’ arguments
SKAT
SKAT made the following points:
- Issue estoppel attaches only to the application of law to particular facts. It does not attach to pure points of law or to steps in the court’s reasoning.
- Precedent and abuse of process adequately guard against repeated litigation.
- Whether an issue was pleaded is critical to whether its determination was necessary.
- The scope of an estoppel cannot be enlarged by inferring that the earlier judge would have reached the same conclusion on different facts.
- Watt v Ahsan concerned the legal quality of facts, not a pure point of law.
EDFM
EDFM made the following points:
- A determination that necessarily formed part of the earlier decision binds the parties even if it is capable of wider application. Necessity is identified in the same way as the ratio decidendi.
- Outram v Morewood, Howlett v Tarte, Jones v Lewis and New Brunswick Railway were estoppel by record cases, or default judgments, and so of limited relevance.
- The estopping issue involved applying the Revenue Rule to a factual situation. The change in SKAT’s cause of action was irrelevant to the judge’s reasoning on that rule.
- SKAT should not be allowed to raise the Arnold exception so late, nor to escape the consequences of a tactical decision not to appeal.
The Court’s reasoning
Lord Sales and Lord Doherty gave the judgment, with which the other Justices agreed. They began from Lord Sumption’s taxonomy of res judicata in Virgin Atlantic, which describes issue estoppel as the principle that:
“even where the cause of action is not the same in the later action as it was in the earlier one, some issue which is necessarily common to both was decided on the earlier occasion and is binding on the parties”
The Court rejected EDFM’s attempt to distinguish estoppel by record. The modern law regards issue estoppel as a form of estoppel by record. In the older cases, the estoppels arose from the judgments, not from the pleadings.
Why issue estoppel must be kept narrow
The Court stressed how far-reaching the doctrine is. When it applies, it involves:
“a serious interference with the ordinary entitlement of litigants to present their claims and to defend themselves according to a proper understanding of their legal rights.”
The Court contrasted issue estoppel with precedent. Under precedent, a litigant may seek to distinguish or overrule an earlier ruling. That possibility is foreclosed by an issue estoppel, and the Arnold exception is narrow. Accordingly, there is:
“no sound reason to give the application of an issue estoppel an ambit as wide as the ambit of the doctrine of precedent.”
The governing principles
The Court set out the following principles as well established.
Necessity. The decided issue must have been necessary and fundamental to the decision. This follows Concha v Concha. A finding that is unnecessary to the decision cannot be appealed, because appeals lie against orders, not findings or reasons.
Pleadings. Whether an issue arose on the pleadings is critical. The Court said:
“The identification of the relevant issue by reference to the pleaded claim for the relief sought (or defence raised) shows how narrow the focus is required to be to identify the extent of any issue estoppel which arises: ie it arises only in respect of the particular claim brought (or defence raised) in the proceedings.”
Immediate foundation, not reasoning. Only the immediate foundation of the ultimate decision can give rise to an estoppel, not the reasoning leading to it. The Court adopted Dixon J in Blair v Curran:
“Decisions upon matters of law which amount to no more than steps in a process of reasoning tending to establish or support the proposition upon which the rights depend do not estop the parties if the same matters of law arise in subsequent litigation.”
Applying this, the relevant facts in 2018 were the allegations of negligent misstatement. Their legal quality, as determined by Andrew Baker J, was that they fell within the Revenue Rule. The preliminary issue had proceeded only on SKAT’s pleaded case. As a result, Andrew Baker J:
“made no findings or assumptions about fraudulent misstatements being made by EDFM and did not determine that such misstatements fell within the scope of the Revenue Rule.”
The Court contrasted a hypothetical case in which the trial judge had found that the relevant words were never used in the applications. A finding of that kind would have estopped SKAT. In reality, the use of the words was never disputed.
Policy reasons
The Court gave several policy reasons for confining issue estoppel:
- The scope of an estoppel should not depend on “the happenstance of how widely or narrowly a judge chooses to frame the reasoning in their judgment”.
- Litigants should not be expected, or encouraged, to contest points that appear peripheral in the first proceedings.
- Abuse of process under Henderson v Henderson is the flexible, carefully balanced mechanism for dealing with points omitted from earlier proceedings. It was accepted here that SKAT had committed no abuse.
- An expansive approach to issue estoppel would cut across abuse of process and would wrongly conflate the immediate foundation of a decision with the ratio decidendi for the purposes of precedent.
No enlargement by inference
Citing the Duchess of Kingston’s Case, the Court held that an estoppel is not conclusive of “any matter to be inferred by argument from the judgment”. It also held that an estoppel arising from one set of facts does not extend to another set, even if the factual differences were legally immaterial to the earlier decision.
The Court found the dicta of Lord Wright, Lord Romer and Lord Maugham in New Brunswick Railway “highly persuasive” and declined to confine them to default judgments. It quoted Lord Romer:
“But he is not estopped from subsequently litigating the question of construction of another document even though the second one be in substantially identical words. For the documents are two distinct documents, and the questions of their construction are two distinct questions.”
Application to the case
The Court decided the appeal on Ground 2. This made it unnecessary to decide whether a “pure” point of law can ever found an issue estoppel. Its conclusions were as follows:
- The 2018 and 2022 Claims involved different causes of action and different factual and legal bases. The basis of the 2022 Claim was not traversable in 2018.
- The majority’s broad formulation was not necessary or fundamental to the dismissal of the 2018 Claim and was not its immediate foundation.
- EDFM’s argument that the Revenue Rule must, on the judge’s reasoning, also apply to fraudulent misstatements was impermissible “inference by argument”.
- Watt v Ahsan did not assist EDFM. It concerned the legal quality of the same facts, namely the Labour Party’s status as a qualifying body, which was the immediate foundation of each claim.
- Nugee LJ’s narrower formulation, although tied to the 420 vouchers, suffered from the same difficulties.
Practical significance
The decision authoritatively confirms that issue estoppel operates within narrow limits. It covers only:
- the ultimate facts necessary to the pleaded claim or defence; and
- the legal quality of those particular facts.
It does not cover the court’s wider reasoning or propositions that might be inferred from it.
The judgment also clarifies the respective roles of three doctrines:
- Abuse of process is the appropriate flexible tool where a party omits allegations from earlier proceedings.
- Precedent governs the reach of legal reasoning.
- Issue estoppel must not be expanded to displace either of them.
Practitioners should therefore identify any estoppel closely by reference to the pleadings and the order made in the earlier proceedings. A party is not barred from bringing a differently pleaded claim, such as fraud rather than negligence, merely because the earlier court’s reasoning would logically have produced the same result.
On the facts, the decision allows SKAT’s substantial fraud claim against EDFM to proceed. The Court noted that, following its 2023 decision, it is not even contended that remedies for fraudulent misstatements fall within the Revenue Rule.
Verdict: Appeal allowed unanimously. The Supreme Court held that SKAT’s 2022 Claim against EDFM was not barred by issue estoppel and should not have been dismissed. It was unnecessary to consider Ground 3, including whether SKAT should be permitted to raise the Arnold special circumstances exception.
