E v N [2026] HKCFI 3293

E lost an HKIACHong Kong International Arbitration Centre arbitration to N and tried to set aside the award in Hong Kong.

E argued, first, that the tribunal had failed to deal with the real issue in dispute. Alternatively, E argued that the tribunal had dealt with it so poorly that enforcement would breach public policy.

Second, E said that earlier Mainland litigation had already decided matters close enough to the arbitration dispute to create an issue estoppel.

And yet, as the court pointed out, the broad jurisdiction objection had not even been properly raised before the tribunal — it appears that point was kept for the set-aside application.

The circumstances of the dispute, and the way the arguments were put, made the case fairly straightforward. It held as follows:

45. Whether the Tribunal is right, or wrong, in reaching its decision on the interpretation of the Contract provisions, and on the Plaintiff’s breach of the Contract requirements, is of course not the subject of review by this Court. As Counsel for the Defendant correctly submitted, even if there was any failure on the part of the Tribunal to set out each step of its reasoning, or to address every argument advanced by the Plaintiff, and even if the Tribunal did not set out a full analysis on the interpretation of clause 21 (as the Plaintiff complains of), that does not constitute a failure to deal with an issue. It is sufficient if the parties who had made their submissions before the Tribunal can, upon reading the Award, understand why the Tribunal had decided against it (whether or not erroneously) (R v F [2012] 5 HKLRD 278).

The far more interesting point relates to issue estoppel. E tried to say that the prior Mainland litigation decision deprived the tribunal of jurisdiction because it had resolved issues later put before the tribunal.

But on the facts, the Mainland decision was not made on the same issues that were later before the tribunal. It concerned guarantee fraud and E’s state of knowledge when calling on the guarantees. It did not decide whether E had breached the sale contract or whether N was entitled to terminate.

The court also held that, even if issue estoppel had arisen, it would not affect the tribunal’s jurisdiction. It would go only to admissibility or the merits of N’s claim. The court held as follows:

18. The simple answer to the Plaintiff’s claim is that even if there was any issue estoppel arising from the Mainland Decision, the matter does not affect the Tribunal’s jurisdiction to deal with the Defendant’s claims and to make the Award in its favor.
19. If the Mainland Court had decided that the Plaintiff was not in breach of the Contract, or was entitled to payment under the Guarantee, as the Plaintiff alleges, issue estoppel only affects the Defendant’s claim and its admissibility, or the merits of the Defendant’s claim, and not the jurisdiction or authority of the Tribunal to consider and decide the claim.

Thus, the set-aside application was dismissed, and E was ordered to pay costs on an indemnity basis.
