Hello and welcome to this Herbert Smith Free Hills Kramer podcast.
00:00:12.880 --> 00:00:21.039
I'm Maura McIntosh, a knowledge counselor in the litigation team in London, and today I'm joined by Damien Grave, a disputes partner based in our Melbourne office.
00:00:21.519 --> 00:00:23.039
Hi Maura, good to be with you.
00:00:23.440 --> 00:00:26.000
And also by Greg Rowan, a disputes partner here in London.
00:00:26.480 --> 00:00:27.199
Hello, Maura.
00:00:27.359 --> 00:00:28.480
Looking forward to the discussion.
00:00:28.879 --> 00:00:35.759
The three of us are the general editors of Class Actions in England and Wales, published by Sweet and Maxwell, which has just gone into its third edition.
00:00:36.000 --> 00:00:44.960
All of the book's authors are Herbersmith Reels Kramer lawyers, many of whom have been involved in some of the largest and most high-profile class actions in this jurisdiction.
00:00:45.280 --> 00:00:53.600
We did a similar podcast four years ago to mark the launch of the second edition, looking at how the landscape of class actions in England and Wales was developing at that point.
00:00:53.920 --> 00:01:02.079
In this episode, we're going to pick up where we left off essentially to discuss what's happened since and also talk a bit about the global context for class actions.
00:01:02.640 --> 00:01:07.920
This is the first in a series of podcasts that we'll be releasing to mark the launch of the third edition.
00:01:08.000 --> 00:01:13.200
And so we're going to look at important areas of class action litigation, which are also covered in the book.
00:01:13.519 --> 00:01:18.560
But getting on with this episode, Greg, let's start by taking stock.
00:01:18.879 --> 00:01:25.599
Four years ago we talked about a steady increase in the number of class action claims being brought and the prominence of this sort of litigation.
00:01:25.840 --> 00:01:26.879
Where are we now?
00:01:27.359 --> 00:01:35.280
Yes, I'd say the trend has continued overall, but it does rather depend on what area we're talking about.
00:01:35.920 --> 00:01:55.359
I think it's fair to say that the um the explosive growth that we had seen in the number of claims being brought under the opt-out regime for competition collective actions in the Competition Appeal Tribunal, that has leveled off to some extent as that regime has developed and uh matured.
00:01:55.519 --> 00:02:00.000
And we've seen the first cases to reach trial and settlement.
00:02:00.319 --> 00:02:04.799
But it does remain a very significant part of the class action landscape.
00:02:04.879 --> 00:02:07.519
And claims certainly continue to be brought.
00:02:07.599 --> 00:02:13.120
Uh, and we'll get into um more detail in a future podcast in the series on that.
00:02:13.520 --> 00:02:20.240
In other areas, we we do continue to see significant numbers of large high-profile claims being brought.
00:02:20.400 --> 00:02:27.599
Um if you just look at the um group litigation uh orders, um it may seem that there's not that much activity.
00:02:27.680 --> 00:02:36.080
Uh, there have only been uh 13 new GLOs listed on the gov.uk website since the last edition four years ago.
00:02:36.240 --> 00:02:48.639
And in fact, 10 of those are part of the uh diesel emissions group litigation, which brings together 13 separate GLOs concerning diesel emissions claims against various manufacturers.
00:02:48.800 --> 00:02:53.280
So it's just three new GLOs if you exclude the emissions claims.
00:02:53.680 --> 00:03:00.400
Yeah, uh I mean we should say the list on the government website isn't necessarily comprehensive or up to date.
00:03:00.639 --> 00:03:04.479
It does say it was last updated in February 2025.
00:03:04.719 --> 00:03:11.039
So, you know, there may have been a few more GLOs than that in the past four years, but I expect it it hasn't been loads.
00:03:11.599 --> 00:03:12.879
Why do you think that is?
00:03:13.439 --> 00:03:21.120
Well, uh GLOs represent really only a small part of the picture of class action litigation in England and Wales.
00:03:21.360 --> 00:03:24.800
So the published list doesn't really tell the whole story.
00:03:24.960 --> 00:03:34.400
Um in many cases the court will manage large numbers of similar claims using its bespoke case management powers rather than making a formal GLO.
00:03:34.879 --> 00:03:39.520
That was actually a trend that we flagged previously, and I'd say that it's definitely continued.
00:03:39.680 --> 00:03:44.479
So the real level of activity is much higher than the headline figures suggest.
00:03:44.879 --> 00:03:55.039
Yeah, I mean I suppose the obvious question is if the GLO was introduced as the main procedural mechanism for handling multi-party litigation, why do you think it isn't used more?
00:03:55.520 --> 00:03:58.960
Yes, it is it is an obvious and a good question.
00:03:59.199 --> 00:04:11.120
I I think the starting point actually is that in many multi-party cases, there it just isn't a GLO application, that the parties are presumably content for the court to manage the case without one.
00:04:11.439 --> 00:04:20.959
And that will often be the case where the claimants are um represented by a single law firm or by a small number of firms that are cooperating to bring the claims.
00:04:21.199 --> 00:04:29.680
So the the GLO machinery for, if you like, corralling separate claimants or claimant groups may actually seem unnecessary.
00:04:29.920 --> 00:04:35.279
Um we we often see that uh in the context of shareholder class actions, for example.
00:04:35.519 --> 00:04:44.800
And sometimes the court will decline to grant a GLO, even if the claimants want one, if it seems likely to add unnecessary cost and complication.
00:04:45.040 --> 00:04:51.360
Again, typically where there are only one or a couple of firms representing all of the claimants.
00:04:51.920 --> 00:04:53.600
Right, yeah, that makes sense.
00:04:53.920 --> 00:05:18.240
I suppose whether there's a
Load full transcript
formal GLO or not, uh we should point out that these claims importantly are brought on an opt-in basis, so that the claimants all have to issue claims and be named on the claim form in contrast to the competition regime you mentioned earlier, which allows claims to be brought on behalf of anyone who falls within a defined class without them having to take any steps to join the litigation or even be named in it.
00:05:18.800 --> 00:05:19.680
Yes, that's right.
00:05:19.839 --> 00:05:31.519
Um there is another opt-out regime that can be used in high court claims, which is um what's known as the representative action procedure, and that is under CPR 19.8.
00:05:31.759 --> 00:05:50.079
Um and what that essentially does is to allow a claim to be brought on behalf of all those who have the same interest in it, but it can't be used to determine issues that depend on um particular circumstances of individual claimants, and most claims will have at least some individual issues.
00:05:50.160 --> 00:05:52.959
So it hasn't really been uh widely used.
00:05:53.439 --> 00:05:54.959
Yeah, absolutely.
00:05:55.120 --> 00:06:04.800
Uh so in our podcast four years ago, of course, we discussed the high-profile decision in Lloyd and Google, which at that point had just been decided by the Supreme Court.
00:06:05.040 --> 00:06:18.399
That case held that uh representative action couldn't be used to bring a claim for damages for alleged breaches of the Data Protection Act 1998 for that reason, because the claims required proof of damage on an individual basis.
00:06:18.800 --> 00:06:36.160
But interestingly, the court in that case left the door open to bringing claims on what they called a bifurcated basis, so that the representative action procedure could be used to determine issues that were truly common, and individual issues could be left over to be determined separately.
00:06:36.399 --> 00:06:44.240
Now, at the time, Greg, I think you were skeptical that we would actually see claims brought on that basis, mainly because of funding difficulties.
00:06:44.639 --> 00:06:45.839
How has that turned out?
00:06:46.399 --> 00:06:47.120
Yes, that's right.
00:06:47.199 --> 00:06:48.879
I was um quite skeptical.
00:06:49.439 --> 00:06:52.560
We have seen some claims, but none that have made it to trial.
00:06:52.639 --> 00:06:56.240
And the funding issues um certainly haven't yet been resolved.
00:06:56.399 --> 00:07:05.759
Um, we'll actually do an episode in the series on representative action specifically, um, which also form the subject of a new chapter in the in the third edition.
00:07:05.920 --> 00:07:09.839
So it probably doesn't make sense to go into too much uh detail on that now.
00:07:10.240 --> 00:07:10.959
Yes, sure.
00:07:11.120 --> 00:07:17.120
Um so let's move on to funding then, which has been one of the big stories, I think, of the last four years.
00:07:17.439 --> 00:07:19.920
Damien, can you bring us up to speed on that?
00:07:20.399 --> 00:07:20.959
Yes, sure.
00:07:21.040 --> 00:07:30.240
The main development over the last four years has been the UK Supreme Court's decision in PACAR, which was handed down in July 2023.
00:07:30.720 --> 00:07:43.920
In that case, the UK Supreme Court held that certain types of litigation funding agreements, which calculate the funders' return as a share of damages, were a form of damages-based agreement.
00:07:44.079 --> 00:07:50.240
And as a consequence, the validity of a large number of those agreements were called into question.
00:07:50.560 --> 00:07:54.160
This caused real disruption in the litigation funding market.
00:07:54.480 --> 00:08:05.920
Litigation funders had to move to restructure existing arrangements and often moved to a return on a multiple outlay basis instead of a share of damages basis.
00:08:06.240 --> 00:08:16.560
This prompted then a review by the Civil Justice Council in its work on a review of litigation funding with its final report released in June 2025.
00:08:17.040 --> 00:08:35.679
The Civil Justice Council recommended the government introduce legislation at the earliest opportunity to clarify the litigation funding agreements were neither DBAs nor claims management services, and that such legislation be prospective and retrospective in effect.
00:08:36.080 --> 00:08:45.759
It also recommended the introduction of a light touch statutory regime of litigation funding through regulations issued by the Lord Chancellor.
00:08:46.000 --> 00:08:51.120
Regulation by the Financial Conduct Authority was not recommended at that stage.
00:08:51.519 --> 00:09:00.559
The government has now accepted these two key recommendations but has not given further detail as yet as to its plans and the timing.
00:09:00.799 --> 00:09:03.600
This has led to continued uncertainty in the market.
00:09:04.080 --> 00:09:05.200
Yeah, absolutely.
00:09:05.279 --> 00:09:12.240
And we're certainly closely following what might happen when we get more news from government on that.
00:09:12.480 --> 00:09:20.320
So in terms of where we're seeing class actions being brought in England and Wales, uh, Greg, what would you say are the most significant areas?
00:09:20.879 --> 00:09:26.879
Well, generally, actually, that they're the areas that we have devoted individual chapters to in the book.
00:09:26.960 --> 00:09:53.519
Um so in the first edition, uh, as well as the chapter on competition claims under the opt-out regime in the CAS, in the Competition Appeal Tribunal, which we've already touched on, we had separate chapters on shareholder claims and on environmental and human rights-based claims, particularly actually those brought against um UK-based parent companies relating to the acts of their subsidiaries overseas.
00:09:53.919 --> 00:10:01.679
Then in the second edition, we added chapters on employment claims, product liability cases, and data protection.
00:10:01.840 --> 00:10:04.240
And all of those are still very much live areas.
00:10:04.399 --> 00:10:17.440
And in fact, product liability in particular has seen really the largest class action ever brought in this jurisdiction with the diesel emissions litigation that I mentioned earlier.
00:10:17.679 --> 00:10:36.720
For the new third edition, in addition to the new chapter on representative actions, which we've already mentioned, there's a new chapter on tax disputes, which are often brought on a multi-party basis given the um the potential for large numbers of taxpayers to be affected by the same issue.
00:10:36.960 --> 00:10:44.000
And also a very interesting chapter on class action arbitration, looking at the potential for that area to develop.
00:10:44.480 --> 00:10:44.879
Thanks.
00:10:44.960 --> 00:10:46.720
Um that's a good overview.
00:10:46.960 --> 00:10:49.440
So let's turn now to the global context.
00:10:49.759 --> 00:11:01.279
Damien, you're obviously well placed to speak to the Australian position since you're based in Melbourne, and of course you're a co-author of the leading Australian text on the subject, which I understand will soon be in its fourth edition.
00:11:01.679 --> 00:11:02.879
Yes, that's right, Moira.
00:11:03.120 --> 00:11:06.879
Uh Australia's a very active jurisdiction for class actions.
00:11:07.039 --> 00:11:16.399
We've had an opt-out class actions regime at the federal level since 1992, and so almost now for 35 years it's been in place.
00:11:16.639 --> 00:11:22.639
There's also a similar procedure which exists in most of the Australian state jurisdictions as well.
00:11:22.960 --> 00:11:31.600
The threshold for commencing a class action in Australia is relatively low, and there is no certification requirement as there exists in the US.
00:11:31.840 --> 00:11:51.440
There's also a very active funding market in Australia, and in addition, in the state of Victoria, there has existed since July 2020 a contingency fee regime which permits lawyers to receive a percentage of any judgment or settlement amount, which is all overseen by the courts.
00:11:51.679 --> 00:11:59.600
What this has all meant in combination is that Australia has been a very active jurisdiction for class actions.
00:11:59.840 --> 00:12:20.639
In the most recent empirical research in Australia on the number of class actions conducted by Professor Moribito, which takes it to the end of calendar year 2024, there's been almost a thousand class actions filed across all jurisdictions in Australia since the commencement of the regime in 1992.
00:12:20.879 --> 00:12:39.200
In terms of types of class actions, those commenced by shareholders are the most prominent by far and away, with also a large number in the area of investors and consumer protection, and also in the area of product liability, and we expect that to continue.
00:12:39.440 --> 00:12:54.240
Some areas to watch include data protection and ESG claims, together with the growth of contingency fees in Victoria, and to keep an eye on whether a similar regime for contingency fees is introduced at the federal level.
00:12:54.720 --> 00:12:54.960
Thanks.
00:12:55.360 --> 00:12:55.679
Interesting.
00:12:55.840 --> 00:12:59.519
Sounds like there's lots going on in Australia as well.
00:12:59.919 --> 00:13:07.200
What about the potential for class actions to be brought on on a global basis in multiple jurisdictions?
00:13:07.519 --> 00:13:07.919
Greg?
00:13:08.639 --> 00:13:17.600
Yes, we we certainly see lots of class actions brought here in the English courts by claimants based in other countries relating to events that occurred in those countries.
00:13:17.840 --> 00:13:21.679
So yes, uh class actions are very international in that sense.
00:13:22.480 --> 00:13:35.759
There's also been a broader trend towards the globalization of class action risk with parallel claims relating to basically the same alleged wrongdoing being brought in multiple jurisdictions.
00:13:36.000 --> 00:13:45.279
So we've seen that, for example, with the trucks litigation in the competition space and with the diesel emissions litigation that we've been discussing.
00:13:45.679 --> 00:13:54.080
It's a risk, particularly where issues arise in relation to globally marketed products or global business practices.
00:13:54.399 --> 00:14:05.039
And what's clear is that claimant firms and funders in various jurisdictions are watching trends elsewhere and really quite quick to follow suit if a new claim opportunity arises.
00:14:05.440 --> 00:14:05.840
Thank you.
00:14:05.919 --> 00:14:10.720
Yes, I'm sure it's something we'll continue to see going forward.
00:14:11.200 --> 00:14:13.600
That brings us to the end of this episode.
00:14:13.759 --> 00:14:22.159
Uh if listeners want to go deeper on any of the topics discussed, uh take a look at the new third edition of the textbook, which is available on Westlaw.
00:14:22.320 --> 00:14:30.080
Uh and also I hope you'll keep an eye out for further episodes in this series where we'll be returning to some of the themes we've discussed in more detail.
00:14:30.240 --> 00:14:33.440
Uh thank you both, Damien and Greg, and thanks to all of you for listening.
00:14:33.759 --> 00:14:34.399
Thanks, Maura.
00:14:34.480 --> 00:14:34.960
Thanks, Greg.
00:14:35.200 --> 00:14:36.240
Yeah, thank you both.
