Res judicata and abuse of process
The principle of res judicata, a Latin term meaning ‘a matter judged’, broadly prevents a party from re-litigating a claim, defence or issue already litigated. This is intended to ensure the finality of judgments and protect litigants from multiple litigations involving the same claims or issues.
Lord Sumption described the principle in Virgin Atlantic Airways Ltd v. Zodiac Seats UK Ltd (formerly known as Contour Aerospace Ltd) [2013] UKSC 46, as including a number of different legal principles. These included:
(a) A rule preventing re-litigation of the same cause of action (cause of action estoppel);
(b) A rule preventing re-litigation in one cause of action of an issue decided in an earlier cause of action and binding on the parties (issue estoppel); and
(c) A general procedural rule against abuse of process.
The Virgin Atlantic formulation also included rules: (d) preventing a successful claimant re-litigating on the same basis for further damages; (e) providing that a cause of action is extinguished once judgment is given (the doctrine of merger); and (f) preventing a party from raising in subsequent proceedings matters which were not, but could and should have been, raised in earlier proceedings (the rule in Henderson v. Henderson).
Notably, both cause of action and issue estoppel apply in respect of prior proceedings between the same parties or their “privies”, being one who claims title or right under, through or on behalf of a party bound by a decision (the principle of mutuality).
Facts and Court of First Instance (CFI) decision
The matter involved litigation proceedings and arbitration proceedings in respect of related claims, but not between identical parties.
The plaintiff (P) and the second defendant (D2) concluded a contract (the Contract) for D2 to carry out construction works. Separately, P entered into a conditional bond (the Bond) with both D2 and the first defendant (D1), an insurance company, whereby D1 agreed to discharge the damages sustained by P on default by D2.
A dispute arose, and, as the Contract and Bond were agreed between different parties and contained different dispute resolution clauses, the parties were later involved in two separate actions:
(a) P commenced litigation proceedings against D1 for breach of the Bond and D2 for breach of the Contract (the Litigation); and
(b) D2 commenced arbitration proceedings against P for breach of the Contract (the Arbitration).
Subsequently D2 applied for, and was granted, a compulsory stay of the Litigation against D2 in favour of arbitration. D2 also applied for and was granted a case management stay (Case Management Stay) against D1 (please refer to our previous alert).
An important consideration in granting the Case Management Stay was that D1 had given an undertaking (Undertaking) that it would be bound by the outcome of the Arbitration between P and D2. The CFI judge held that the Undertaking would prevent inconsistent findings in the Arbitration and the Litigation.
The present case concerned P’s application for leave to appeal against the Case Management Stay.
CA decision
P’s main grounds for opposing the Case Management Stay arose from the fact that the Litigation and the Arbitration did not involve identical parties, and so the mutuality principle was not engaged and there could be no res judicata.
Consequently, P argued that any findings in the Arbitration would only bind parties to the arbitration agreement, namely P and D2. D1’s Undertaking did not extend res judicata or issue estoppel to bind P and D1.
CA rejected P’s contention.
(a) CA agreed that in the absence of mutuality, cause of action estoppel or issue estoppel did not apply to the present case to bind P.
(b) Having said that, CA observed that, under Lord Sumption’s definition in Virgin Atlantic, the principle of res judicata encompassed other general legal principles, including abuse of process. The abuse of process did not require mutuality and it could be engaged by a party mounting a collateral attack on a previous decision and thereby bringing the administration of justice into disrepute, in which case the abusive proceedings should be struck out.
(c) Applying the abuse of process principle, CA noted that D1’s liability to P was contingent on D2’s liability to P and the underlying issues in the Litigation were the same as those in the Arbitration. If the arbitration findings were in favour of P, D1 would be bound by its Undertaking. If the arbitration findings were against P, it would be an abuse of process to allow P to re-litigate against D1 since P already had an opportunity to litigate the same issues in the Arbitration.
Based on the above reasons, CA held that the arbitration findings would also be binding as between D1 and P. Accordingly, CA refused to grant leave to appeal against the Case Management Stay.
Lastly, CA granted a costs order nisi on summary assessment in favour of D2.
Conclusion
This case confirms the application of the res judicata principle in Hong Kong in the context of arbitration, in line with the position under English law. The res judicata principle encompasses not just issue estoppel and cause of action estoppel, which require mutuality, but also abuse of process, which might bar collateral attacks on arbitration findings in proceedings with third parties. The specific fact pattern in this case is also worth noting: the decision might have been different had D1 not provided the Undertaking or had the Litigation and the Arbitration not had so many overlapping issues. In applying the abuse of process principle, Hong Kong courts will consider each case on its own facts and circumstances.
