The Class Actions Law Review: Hong Kong

Introduction to the class actions framework

In the Hong Kong Special Administrative Region of the People's Republic of China (Hong Kong), the sole machinery for multiparty proceedings comes in the form of representative proceedings, which are commenced by or against a representative plaintiff or defendant on behalf of persons who share the same interest. The judgment in a representative action is binding on all persons represented by the representative plaintiff or defendant though it shall not be enforced against any person who is not a party to the proceedings except with the court's permission. This representative proceedings mechanism is available in the High Court,2 District Court3 and Small Claims Tribunal.4

Hong Kong inherited this current multiparty litigation model from England, but it has not followed the latter's reforms on group litigation orders with the enactment of the Civil Procedure (Amendment) Rules 2000,5 nor the collective proceedings regimes under the Consumer Rights Act 2015.6 As explained in this chapter, the representative proceeding model has its limitations, and reform has been called for. Indeed, representative proceedings remain rare in Hong Kong, and the jurisprudence in this area is rather limited.

Hong Kong has been exploring the option of introducing a dedicated scheme for multiparty litigation. In March 2004, the Chief Justice's Working Party on Civil Justice Reform released its final report on 150 recommendations in respect of reforms to be introduced to the civil justice system. One of the recommendations was to adopt a scheme for multiparty litigation.7 A sub-committee of The Law Reform Commission of Hong Kong (LRC) was then tasked to make suitable recommendations on multiparty litigation and subsequently launched a public consultation in 2009 to gather opinion.8 Upon completion of the public consultation in May 2012, the LRC published its Report on Class Actions (the LRC Report) proposing, in particular, that Hong Kong introduce a multiparty litigation model with an 'opt-out' approach.9 The opt-out model envisages that upon the court certifying a class of persons as suitable for a class action suit, all the members of that class (except foreign parties) would be automatically bound by the outcome, unless any of them indicate a wish to be excluded from the action. The LRC Report recognised that class actions commenced in Hong Kong may straddle numerous jurisdictions and involve foreign plaintiffs. Where they involve claimants from mainland China, for example, legal ambiguity exists as to whether the mainland courts would recognise and enforce class action judgments with an opt-out approach. Thus, under the LRC's recommended model, a foreign plaintiff must expressly opt in to the class action to benefit from the judgment.

The LRC also proposed implementing the class action regime in phases. At the outset, class actions could be launched in consumer cases, where the general consensus was that, due to the number of potential claimants involved whose claims, individually, might be relatively insignificant, they are suitable to be dealt with by way of class actions. It was recommended that funding for class action litigations in consumer claims would be made available by expanding the financial scope of the existing Consumer Legal Action Fund managed by the Hong Kong Consumer Council. The LRC also foresaw the need to establish a general class action fund to cater for the need of class action litigants should the class action regime extend beyond consumer cases.

Also relevant to the development of a class action regime in Hong Kong is the introduction of the competition law regime in Hong Kong. Similar to consumer claims, competition claims involve a potentially large pool of victims of anticompetitive conduct with individual claims of insignificant amount, and, therefore, is another area where a class action regime would be beneficial. Despite the Competition Ordinance (Cap. 619) taking effect from December 2015, collective actions do not yet feature in a competition law context. This contrasts with recent developments in England where an opt-out collective proceedings regime was established in 2015 for competition law claims in the Competition Appeal Tribunal, and there have been high profile landmark cases being litigated in recent years.10

The story of class action regime in Hong Kong, in recent years, has become intertwined with that of a weighted voting rights (WVR) regime. In 2014, Hong Kong Exchanges and Clearing Limited (HKEX), the operator of the stock exchange in Hong Kong, published a consultation paper seeking views on whether companies with WVR structures – governance structures that give certain persons voting powers or related rights disproportionate to their shareholding – should be permitted to list on the Exchange.11 Among the consultation issues was the viability of class action lawsuit as a means of redress for minority shareholders.

In June 2015, the HKEX released the consultation conclusion.12 While a small number of responses stated that the introduction of a class action regime was a necessary pre-requisite to allowing WVR, twice as many responses disagreed. Those who disagreed noted that in the US, class action cases are most often brought to seek remedies for misconduct concerning disclosure of information,13 but not for the type of governance issues usually arising from WVR structures. Some respondents claimed that the existing connected transaction rules, the Codes on Takeovers and Mergers and Share Buy-backs, and laws on directors' fiduciary duties were adequate to protect shareholders. Others submitted that the Securities and Futures Commission (SFC), the statutory securities market regulator, had powers under the Securities and Futures Ordinance (Cap. 571) (SFO) to seek class remedies on behalf of shareholders, which provided important protection against corporate behaviour that amounts to oppression or unfair prejudice, and was, therefore, much better placed to protect shareholder rights than legal counsels in class action lawsuits who may have different motives. Still others were concerned about the higher risk of frivolous cases being brought under a class action regime and the ensuing disincentive to companies listing in Hong Kong due to the potential cost of defending and settling class actions. In response, it was concluded that a class action regime was not a necessary prerequisite for the acceptability of WVR structures. The new Listing Rules Chapter 8A14 permitting listing of companies fulfilling certain criteria with WVR structures came into effect on 30 April 2018, without the prior implementation of a class action regime.

The year in review

It was recommended in the LRC Report that a working group comprising representatives of the major stakeholders should be formed to consider the details of the proposed class action regime. Subsequently, in May 2012, the Hong Kong Department of Justice (DoJ) formed a cross-sector Working Group on Class Actions (the Working Group) comprising representatives from the private sector, legal profession and Consumer Council.

The Working Group focused its study on implementing the class action regime through an incremental approach starting with consumer cases and considered issues such as the proposed definition of 'consumer cases', certification criteria to be adopted by the court, as well as the relevant procedural rules and ancillary measures.15

Several years after its formation, on 31 December 2020, the Working Group announced its intention to commission a consultancy study on the economic and other related impacts on Hong Kong if a class action regime is to be introduced, initially restricted to consumer disputes.16 In the meantime, the Working Group has started drafting the consultation paper.17

Numerous recent incidents in Hong Kong have highlighted the need to have a more systematic multiparty litigation mechanism; this need calls for the class action reform to be expedited. One of these incidents is the discovery in 2015 that drinking water in certain public housing estates was contaminated by heavy metals, which at the time led to suggestions that a class action model would have been the most effective procedure for resolving claims from numerous affected occupants against the Housing Authority and responsible contractors.18 In 2020, an estimated 88 Hong Kong travel agencies closed as the city's tourism industry was forced to a standstill by the covid-19 pandemic. At its peak, some of the travel agencies owed thousands of customers over HK$10 million. Although the Travel Industry Compensation Fund provides an ex gratia payment equivalent to 90 per cent of outbound fares, it does not provide protection for many other travel-related losses. Nor does it provide funding for consumer representative proceedings.19 In situations such as these, the presence of a class action regime would have facilitated access to justice to victims concerned.


i Types of action available

Representative plaintiff

In contrast with US-style class actions, representative proceedings in Hong Kong are more aptly characterised as a case management mechanism, the essential purpose of which is to ensure cases are run in a manageable and cost-effective fashion. In cases where parties are so numerous that the proceedings could be rendered unmanageable if all were named, the judiciary would achieve its case management objectives if the issues common to all plaintiffs can be decided in a single set of proceedings rather than manifold proceedings, all of which seek substantially the same reliefs.

A representative action under the Rules of the High Court (Cap. 4A) (RHC) Order 15, Rule 12 may only be brought where all members of the represented group have the same interest. The question as to whether a group of claimants share the same interest involves the threefold test of: (1) common interest; (2) common grievance; and (3) a remedy that is beneficial to all.20 Accordingly, a potential conflict of interest between the members within the represented group might be a factor against establishing that the same-interest requirement has been satisfied.21

The courts have historically adopted a very restrictive interpretation of the term 'same interest' and required all members of a class to show identical issues of fact and law. As a result, class members had to establish that: (1) the same contract applies between all plaintiff class members and the defendant; (2) the same defence is pleaded by the defendant against all plaintiff class members; and (3) the same relief is claimed by the plaintiff class members.22 Accordingly, under this restrictive interpretation, where consumers have contracted separately with the supplier under the latter's standard form contract, they could not pursue a claim by way of representative actions under RHC Order 15, Rule 12. Also, the same relief requirement meant that damages, which have to be proved separately in the case of each plaintiff, could not be obtained in a representative action. Instead, equitable reliefs such as injunction was the main remedy in representative proceedings.23 The strict interpretation of 'same interest' may account for why representative proceedings in Hong Kong were uncommon.

Over the years, the courts have relaxed the same interest test and adopted a 'common ingredient' requirement instead. It is now sufficient that there is a common ingredient or some common element in the causes of action of the represented class members.24 Once a common ingredient is established, class members can rely on the judgment on the common ingredient as res judicata and proceed to prove the remaining elements of the cause of action in separate proceedings.25 Behind this relaxation of the same interest requirement is the aim of making representative actions 'not a rigid matter of principle but a flexible tool of convenience to facilitate the administration of justice'.26

Apart from the emergence of the 'common ingredient' formulation, other judicial developments contributed to the relaxation of the common interest test. These developments included: (1) removing the requirement that there be a single contract between the class of plaintiffs and the defendant;27 (2) allowing separate defences to be pleaded by the defendant against different members of the plaintiff;28 and (3) greater judicial willingness to award damages in representative actions.

If a representative plaintiff withdraws from the representative proceedings, the court may add or substitute him or her with any person in the represented class. The new plaintiff is treated as having been the representative plaintiff from the date of the original writ. This avoids the claim from being time-barred if the addition or substitution occurs after the limitation period for the relevant claim.29

In certain restricted circumstances, the court has the power to appoint one or more plaintiffs or defendants to represent a class of persons whose identities may not all be known at the time when action is commenced or persons not yet born. These restricted circumstances include proceedings concerning: (1) the estate of a deceased person; (2) property subject to a trust; and (3) the construction of a written instrument, including legislation.30

Notwithstanding that it has become easier to commence representative proceedings given the more liberal approach to the interpretation of 'same interest' adopted by the courts, the LRC Report highlighted the following deficiencies of the current representative proceedings regime:

  1. compared with US-style class actions, the requirements for representation orders remain technical and narrowly defined;
  2. even where a representation order has been made and the case proceeded to judgment, finality is not necessarily achieved as individuals are still free to challenge enforcement on the basis that there are facts and matters peculiar to his case; and
  3. the existing rules make no specific provision for handling the special problems of multiparty litigation that require forceful case management by the judge, for example, where class members with strong cases might wish to eliminate those with weak cases from the proceedings.31

Without rules designed to deal specifically with group litigation, courts have to proceed on an ad hoc basis, and the resulting uncertainty discourages the employment of the representative proceedings process.

Representative defendant

Similar to representative plaintiffs, RHC Order 15, Rule 12 allows a plaintiff to sue two or more defendants representing a class of individuals who may be unknown to the plaintiffs but are bound together by being members of a club, society, association or other identifiable group of individuals. The same-interest requirement is also applicable in the appointment of a representative defendant.

No leave is required by the plaintiff to bring an action against the representative defendants or to select the person he or she will sue as representative defendants. However, where, after proceedings have been commenced, the plaintiff seeks to appoint any one or more of the existing defendants as representative defendants, an order is required.32

ii Commencing proceedings

Representative plaintiff

A representative plaintiff does not require leave to commence representative proceedings. The representative plaintiff can elect himself or herself to be the representative without needing to seek the consent of those being represented.33 However, the court has power to order that the proceedings cease to continue in the form of representative proceedings if it is of the view that the proceedings are inappropriate to be continued in that manner. Circumstances where the court may disallow continuation of a representative action include cases where the parties seeking or selected to represent others are not suitable representatives or do not fairly represent others having the same interest.34

Representative defendant

A claimant does not require leave to bring an action against representative defendants, or select the person he or she will sue as representative defendants. However, at any stage after commencement of proceedings, the plaintiff would need to obtain an order should he or she wish to appoint one or more of the existing defendants as representative defendants.35 The application is to be made by summons before the master, and should be made as soon as practicable. The representative capacity of the defendants must be indorsed on the writ and stated in the title of the action.36

The court would not leave the matter of the appointment of appropriate representative defendants to the plaintiff or defendants, and would instead make a representation order after satisfying itself that the representatives are proper persons to defend on behalf of others.37 Therefore, the wishes of the plaintiffs and defendants would not dictate the choice of representative defendants. Individuals may also be appointed representative defendants to defend on behalf of others against their will.38 In exercising its discretion, however, the court may take the individual's unwillingness to act in representative capacity into account, and consider other factors such as whether the duties imposed upon the representative defendant or defendants would be unduly burdensome, including the obligation to inform persons potentially falling under the class of defendants, and the costs and time involved in acting as the representative defendant. It may also consider viable alternative reliefs for the plaintiff, such as an action to sue defendants named as 'persons unknown' by describing the role and nature of that person, with amendment later if their identities become known.39

iii Defining the class

In a representative action, the writ should clearly and precisely define the class of persons sought to be represented40 and should be indorsed with the representative capacity of the plaintiffs or defendants. The representative capacity of the plaintiffs or the defendants should also be included in the title of the writ and the statement of claim.

The class must be clearly defined, as the ambit of the class affects such practical matters as who will be bound by the judgment, and who might be liable for costs. A vague definition of class would also hamper the ability of the representatives to inform the potential class members of the proceedings. It is not sufficient to state that the representative represents some of the members of a class without defining who are to be excluded.41 If persons have been excluded from the definition of class, they should be made parties in their personal capacity. The court would consider any potential conflict of interest (or absence thereof) between the members within the represented group in allowing or disallowing the representative action.42 There do not appear to be bars to overseas persons being included in a class provided the common interest test is satisfied.43 As explained above, the members of a defined class should have sufficient common interest between them to satisfy the common interest test.

The class must also contain 'numerous persons'.44 This is so given the objective of the representative proceeding rule was to facilitate disposition of cases where parties were so numerous that the proceedings would be unmanageable if all were named. While there is no set number required, a group of a few people (for example, five persons) is unlikely to be sufficiently numerous, unless the individual claim amount is very small or the court is satisfied that it is the wish of all persons interested that a representation order should be made.45

Where the class is too small to constitute a class of 'numerous persons', the class is not capable of being clearly defined or other considerations apply that make it inappropriate for representative proceedings to continue, the court may consider other viable reliefs, such as granting an action to sue additional defendants as persons unknown and describing the role and nature of those persons, with amendment later if identities become known.46

iv Binding effect on the class

The fundamental principle of a representative action is that, if the representative action is properly conducted, all members of a class represented are bound by any judgment or order given in the action, as they are treated as being present in the proceedings by representation notwithstanding that they are not named parties to the proceedings.47 Not only are judgments given after trial binding on those represented, but judgments entered in default of notice of intention to defend are also binding. In the latter case, however, a person being represented can apply to be added as a named defendant and seek to set aside the default judgment, in order to bring the matter to trial. Further, if he or she can demonstrate fraud, collusion or other issues of similar nature, he or she may apply to have the judgment set aside. Otherwise, judgments given after trial cannot be challenged except on appeal.48

v Procedural rules


Leave is not required to enforce a judgment against the representative plaintiff or defendant, who is a named party to the proceedings.

Leave is, however, required to enforce a judgment against a member of the represented class who is not a named party to the proceedings. Application is made by summons before the master, and personal service of the summons on the person against whom the judgment is sought to be enforced is required.49

A represented member only has limited tools at his or her disposal to resist the enforcement of a judgment, namely that there are facts and matters particular to the case so that he or she is entitled to be exempted from liability arising from the judgment.50 An example is that he or she was not in fact a member of the class represented at the time the cause of action arose. The individual member cannot challenge the validity or binding nature of the judgment and cannot put forward any defence that could have been (but was not) raised in the proceedings.

The difficulty of resisting enforcement of the judgment, together with the binding nature of the representative proceedings, and the lack of consent required from class members before a representative plaintiff commences proceedings underscore the importance for individual members to opt out of representative proceedings by ensuring they are specifically excluded from the member class.

Judge or jury

All civil actions in Hong Kong are heard by a single judge in the first instance with the exception of defamation cases, which may be heard by a jury, depending on the level of court in which the defamation action is brought.

Speed of the litigation

It is difficult to generalise the time it takes for the disposition of representative proceedings in Hong Kong, particularly in light of the underutilisation of the regime and the resulting lack of empirical data. Various factors affect the time it takes for representative proceedings to reach trial and judgment, including the nature of the claims made, the complexity of the claims and the court diary. While representative proceedings are commonly perceived to promote judicial efficiency by resolving a large number of disputes in which there are common issues of fact or law within a single set of proceedings, this efficiency may not be achieved on an individual case basis. Various issues peculiar to representative proceedings tend to lengthen the time required to obtain substantive judgment in representative proceedings, such as disputes on whether a representative proceeding is suitable for the particular case, the choice of representatives, definition of class and time needed for representatives and their legal counsel to communicate and liaise with class members.

Liability and quantum

Historically it was not possible to claim damages in a representative action as this offended the rule that the represented class members should only claim the same relief. As a result, declaratory and injunctive reliefs were the default reliefs in a representative action. The recent trend has been for the courts to relax this rigid approach by facilitating claims for damages through making a declaration of the class members' entitlement to damages, which then enables class members to claim damages individually.51 Courts have also declared that the defendant owed the plaintiff class a lump sum without making any individual assessments,52 and allowed damages in different measures where this claim was an adjunct to the primary equitable relief claimed such as injunction.53

Damages and costs

The usual measure of damages in Hong Kong is compensatory damages, which put the innocent party in the position it would have been in had the contract been properly performed or if the tort had not occurred. Punitive or exemplary damages are rarely awarded by Hong Kong courts. The very limited circumstances in which punitive damages may be awarded include where the defendant's conduct was calculated to make a profit over and above the compensation payable to the claimants. As most civil cases in Hong Kong are heard by a judge, damages are usually awarded by the presiding judge.

As for costs, only representative plaintiffs who are named parties in the proceedings are liable for costs; other represented members of the class who are not named parties are not liable. It remains to be seen whether this seemingly unfair position will change when a comprehensive class action system is finally introduced in Hong Kong. For example, under the Civil Procedures Rules 46.6(3) in England and Wales, common costs may be ordered, meaning that group litigants would be severally liable for an equal proportion of the litigation costs.

In respect of funding, Hong Kong still maintains the common law offences of champerty and maintenance. While the offences no longer apply to arbitrations,54 their continued applicability in relation to general litigation has been reaffirmed by the Court of Final Appeal, the highest court in Hong Kong.55 Under the principle of maintenance, a person with no interest in a legal action of another should not meddle in the action by providing assistance, and under the principle of champerty, a person shall not obtain a share of proceeds of another's legal action as a reward. The established categories of exceptions to the principles of champerty and maintenance are where the third party has common interest with another in the litigation, where there are access to justice considerations, and in insolvency proceedings.56

As mentioned above, the LRC Report recognised the importance of a suitable funding model for any class action system to have any practical meaning. It has proposed expanding the Consumer Legal Action Fund to make funding available for class action proceedings in respect of consumer claims. It further recommended that in the long run, a general class action fund be set up that will make discretionary grants to eligible impecunious class action plaintiffs.


A representative may discontinue or settle the proceedings prior to judgment. However, in such a case, the represented members may commence their own proceedings or apply to be made defendants in the first action. After judgment, a representative plaintiff has no power to discontinue, settle or deprive class members of the benefit of the judgment, as after judgment, no class members may bring further action in respect of matters adjudicated in the first action.57

Cross-border issues

In principle, as long as overseas plaintiffs or defendants share the same interest as the representative plaintiff or defendant, they may be included in the class, subject to the normal rules of service out of jurisdiction.58

Outlook and conclusions

Hong Kong's existing representative proceedings system remains an underutilised mechanism for plaintiffs pursuing collective claims. Some proponents view that the existing representative proceedings could be significantly improved by way of strong court control and case management. However, piecemeal judicial developments would unlikely remove the significant uncertainty in adopting the representative action procedure.

Some believe that alternative dispute resolution mechanism such as arbitration and mediation could provide sufficient, efficient and fair redress for collective claims.59 There are others who believe the current statutory regime sufficiently provides for those claims to be brought by regulatory bodies on behalf of lay claimants. For instance, the SFC can protect victims who have been harmed by securities-related misconduct or misfeasance through legal actions under the SFO.60 However, in reality, alternative dispute resolutions cannot be a complete substitute for a comprehensive class action regime. Further, given the heavy caseload of the regulators, which necessitates prioritisation of cases, and the amount time it might take for them to investigate the matter and pursue claims to trial, the availability of a comprehensive class regime is believed to supplement the current statutory regime and likely to improve access to justice.

Looking forward, the LRC Report has proposed implementing the class action regime incrementally. It has identified 16 types of cases that might be suitable for class action proceedings, such as insurance, labour disputes, consumer, securities and competition cases.61 There are recent events that further the impetus to accelerate the discussion on the introduction of a comprehensive class action regime in Hong Kong. These include the liberalisation of the listing regime, including that relating to individual and corporate WVR beneficiaries, biotech companies and companies seeking secondary listing in Hong Kong (which are perceived to expose shareholders to higher risks), and the continued development of the competition law regime in Hong Kong. Further, the PRC has also recently through its revised Securities Law introduced a securities class action system in respect of misrepresentation on securities, insider trading and market manipulation.62 With the close judicial cooperation between the PRC and Hong Kong, the increased enthusiasm for class actions in the PRC might spark new interest in Hong Kong for introducing a proper class action regime.

There has long been a debate that a proper class action regime in Hong Kong would adversely affect the economy by deterring investments and harming small- to medium-sized businesses. The covid-19 pandemic and its adverse impact on the global economy may, unfortunately, add uncertainties to the development of a comprehensive class action regime in Hong Kong.
