Supreme Court releases new opt-out class action decision

19 November 2020

​The Supreme Court released a decision this week that will likely have a significant effect on New Zealand's class action regime for years to come: Southern Response Earthquake Services Ltd v Ross [2020] NZSC 126.

The Supreme Court ruled that “opt-out" class actions are permitted in New Zealand, and that in many cases this will be the starting point for a class action. This will have a significant effect on the nature and impact of class actions, with consequences for consumers, investors, corporates, litigation funders and insurers.


Mr and Mrs Ross brought proceedings against Southern Response, alleging that Southern Response had failed to provide them with information about the cost to rebuild their house before they settled their insurance claim. The Rosses sought orders allowing them to bring the proceedings not only for themselves but also on behalf of 3,000 other insureds who had settled with Southern Response.

The Rosses also asked permission to bring the proceedings on an “opt-out" rather than an “opt-in" basis. An opt-out proceeding would allow the Rosses to sue on behalf of all other insureds without obtaining their consent (unless they specifically say that they do not wish to participate).

Opt-out proceedings are common in other jurisdictions, including the United States and increasingly Australia, but before now all class actions in New Zealand have been opt-in.

There is no detailed class action regime in New Zealand, and proceedings must be brought under a relatively brief provision in the High Court Rules, which allows a person to sue on behalf of others with the same interest with their consent or by an order of the Court. There have been various efforts to introduce a more detailed regime, but these have all stalled. The Law Commission is currently in the early stages of investigating whether to make legislative reform, but has not yet issued any consultation document or recommendations for reform.

The High Court in the Ross proceeding ruled that opt-out orders were not available in New Zealand, and therefore declined to make the orders the Rosses sought. That decision was consistent with a reasonably long line of other decisions that ruled the same way.

The Court of Appeal, however, overturned the High Court and ruled that the courts had jurisdiction to make opt-out orders, and that an opt‑out order was appropriate in this case. The Court of Appeal considered that this would facilitate improved access to justice, because it would result in better participation in class actions. The counterargument, mounted by Southern Response, was that without a detailed class action regime (as exists in other jurisdictions), class actions would involve excessive and costly proceedings to determine the procedural details, and there would be insufficient protections for members of the class who were not aware of the proceeding.

The Court of Appeal's decision was itself a landmark case, but it remained to be seen whether the Supreme Court would agree that opt-out class actions should be permitted in the absence of legislative reform.

Supreme Court decision

We now have the Supreme Court's view. It unanimously endorsed the Court of Appeal's approach, and in some respects went further. There are a number of key points that consumers, investors, corporates, litigation funders and insurers should be aware of following the Supreme Court's decision:

  • The Supreme Court ruled that the courts have jurisdiction to make opt-out orders in New Zealand, even in the absence of a specific statutory class action regime.
  • The objectives of the jurisdiction to bring class actions are improving access to justice, facilitating efficient use of judicial resources, and strengthening incentives for complying with the law. The Court ruled that opt-out class actions are consistent with these objectives.
  • The default position will be the procedure sought by the applicant. The Court will only depart from this if there are good reasons to do so, considering what will best meet the permissible objectives of the representative action in the particular case.
  • The plaintiff conducting the proceeding has the power to settle on behalf of the other class members.
  • The courts have wide powers to control how class actions are run. This includes the power to approve settlements, which should generally be a condition of making an opt-out order.
  • The Supreme Court accepted that absent a detailed regulatory class action regime, class actions will involve more procedural uncertainty, and that this will require many issues to be determined by the courts. However, the absence of a more detailed regime that did not preclude the courts from making opt-out orders under the existing rules.

Interestingly, a separate New Zealand litigation funder, LPF Group, made submissions against the Rosses and their litigation funder, in support of Southern Response's position. LPF argued that opt-out class actions should not be permitted in the absence of a detailed legislative regime. However, the Supreme Court rejected this submission.

Implications for class actions in New Zealand

The Supreme Court's decision will have a significant effect on the class action landscape in New Zealand. It is unlikely that there will be any reform of the current rules any time soon, given the ongoing Law Commission review, and even then it is by no means clear that Parliament would have an appetite to overrule the Supreme Court's decision.

As a result, it seems likely that opt-out class actions will become more common in New Zealand. If the Australian and American experience of opt-out class actions is anything to go by, this will likely mean corporates, and particularly companies listed on the NZX or ASX, may face a greater risk of such a claim. The increase of class action claims in Australia has had an effect on directors and officers insurance premiums on both sides of the Tasman. Confirmation of the availability of opt-out proceedings in New Zealand may well exacerbate the impact that we have been seeing on premiums.

Finally, the Supreme Court expressly declined to consider whether there was jurisdiction to make what are called “common fund orders". That is an order that members of the class contribute to the litigation costs of the action, normally through a deduction from the damages owing to each class member if the action succeeds. That issue is currently before the High Court in the Ross proceeding. We will continue to follow developments on this and other class action issues.
