The rapid rise of mass arbitration has caused consternation among US companies, while the varied approaches to experts and claims administration were laid out at the Global Class Actions Symposium 2025.<\/strong><\/p>\n\n\n\n

The range of mass disputes now taking place goes far beyond traditional class actions. Speakers on the second afternoon (19 November) of the Global Class Actions Symposium 2025, hosted by CDR<\/em> parent company Global Legal Group, elaborated on the growth of mass arbitration.<\/p>\n\n\n\n

Arbitration frustration<\/strong><\/h3>\n\n\n\n

Describing mass arbitration<\/a> as \u201ca relatively new mass action business model that has become prevalent in the US\u201d, panel chair Kris Comeaux of Analysis Group highlighted data showing that more than 500 plaintiff law firms had filed consumer mass arbitration demands since the start of 2024, \u201cjust the tip of the proverbial iceberg, as much of the activity around mass arbitrations happens even before demands get filed\u201d. Despite this, fewer than 1% of the cases filed with those arbitral venues result in a decision on the merits in favour of consumers, Comeaux added.<\/p>\n\n\n\n

This volume has become a point of contention for defence lawyers. Michael McTigue of Skadden, Arps, Slate, Meagher & Flom explained that mass arbitration had arisen out of the 2011 Supreme Court ruling in AT&T Mobility v Concepcion <\/em>that class action waivers, forcing disputes into arbitration, were enforceable.<\/p>\n\n\n\n

As the defendant has to pay the majority of the arbitration fee, claimants are increasingly launching parallel cases, putting pressure on defendants in the hope of forcing a settlement. \u201cOn the defence side some call this \u2018extortion\u2019,\u201d McTigue said.<\/p>\n\n\n\n

The impact of the filings is compounded because \u201ctypically the class action waiver clauses also include a bar to consolidation\u201d, stopping cases being combined into one proceeding, said claimant lawyer Jonathan Waisnor of Labaton Keller Sucharow. The lack of a clear voice organising, managing and consolidating cases, unlike in litigation where \u201ccourts will bring the plaintiffs\u2019 firms together and work out a leadership structure\u201d, was a consequence, although the increased use of \u2018process arbitrators\u2019 to handle procedural issues is beginning to streamline the preliminary stages.<\/p>\n\n\n\n

Amy Morrissey Turk of McGuireWoods, another defence lawyer and formerly an in-house counsel, was similarly troubled, querying the tactics used by claimant firms to sign up class members. In the absence of a judge, \u201cthe defence Bar becomes the gatekeeper of the legitimacy of some of these claims\u201d, she said, warning that \u201cthere has been abuse in certain cases\u201d. However, she accepted that there is value in finding \u201credress for the people that actually exist\u201d.<\/p>\n\n\n\n

Waisnor identified three categories of mass arbitration: data privacy or breach claims, financial services claims and state-level trade legislation. \u201cNobody wants to waste time\u201d with unsuccessful claims, he said.<\/p>\n\n\n\n

McTigue expressed further frustration at the way claims are solicited through targeted advertising, in which it is often unclear what claimants are signing up for. \u201cThere isn\u2019t sufficient vetting by some of these claimant lawyers in connection with gathering these claimants.\u201d<\/p>\n\n\n\n

He warned of mass deficiencies in classes, although Waisnor responded that claimant firms are attempting to improve the quality of class bookbuilding.<\/p>\n\n\n\n

Comeaux said: \u201cMass arbitrations are unintended consequences of poorly written arbitration clauses,\u201d and McTigue explained how clauses are now being rewritten to reduce mass arbitration risk, creating pre-arbitration dispute resolution provisions and claims verification. \u201c[Companies] actually want to do right by their customers, by their employees,\u201d he argued. \u201cThere\u2019s an incentive on their part to see if we can get a resolution \u2013 if the other side is reasonable.\u201d<\/p>\n\n\n\n

The role of experts<\/strong><\/h3>\n\n\n\n

In the UK, recent cases have shone a light on the role of experts, according to a panel led by Anca Cojoc of Cornerstone Research.<\/p>\n\n\n\n

As Andrew Leitch of Hogan Lovells explained, the recent victory for the claimants in Kent v Apple<\/em><\/a> created uncertainty over how the Competition Appeal Tribunal (CAT) will view excessive pricing, as it distinguished the definition from that in Le Patourel v BT<\/em><\/a> where the pricing was held to be justified. \u201cIt\u2019s not entirely clear to me how you weigh those up, in future cases what factors are going to lead to a price being fair or unfair?\u201d<\/p>\n\n\n\n

Leitch went on to say that the CAT had been \u201coverly permissive\u201d, adding: \u201cI’m not concerned about [the CAT] being misled by unscientific evidence,\u201d he said. \u201c[But] it has allowed arguments to be run that are pretty hopeless. And that\u2019s not to say that necessarily prejudices the outcome at a trial, but it does massively ramp up costs.\u201d<\/p>\n\n\n\n

Can \u00c7eliktemur of the Brattle Group described Kent<\/em> as \u201ca landmark judgment\u201d but did not predict a resulting flurry of new cases \u2013 \u201cit is too early to tell\u201d \u2013 because it dealt with a complex market question. \u201cFrom an economist\u2019s perspective, both [Kent<\/em> and Le Patourel<\/em>] relied heavily on expert evidence when coming to their assessment of economic value issues.\u201d<\/p>\n\n\n\n

Andreas Groehn, based in Washington, DC, with BRG, gave an international expert\u2019s perspective on Kent<\/em>, noting the judge\u2019s criticism of one expert for being \u201cmore of an advocate for his client than an independent expert with a duty to the court\u201d.<\/p>\n\n\n\n

Groehn highlighted the differences between giving expert evidence in the UK and US, including the more limited discovery rules in the UK, the use of market research surveys in the US, and the differing approaches to questioning experts, where in the US they will be cross examined at length, and in the UK there is a preference for \u2018hot tubbing\u2019 to obtain more unanimity. \u201cIn the UK there is this debate between the experts which appears to me a little bit more human and possibly more productive than what I see in the US.\u201d<\/p>\n\n\n\n

He also highlighted the use of conjoint surveys in the US as \u201ca very flexible tool\u201d. \u201cThe economies of scale that we have make survey design and the analysis quite efficient and cost-effective,\u201d he added. \u201cI am convinced that judges here in the UK reviewing class actions will benefit from survey evidence, as mentioned in the Kent<\/em> judgment.\u201d<\/p>\n\n\n\n

\u201cThe CAT is getting more proactive in trying to manage experts,\u201d noted Cojoc, reflecting the introduction of page limits and report cards. \u00c7eliktemur sympathised \u201cwith what CAT is trying to achieve with this page limit approach, perhaps that they are trying to make the process of the expert evidence as helpful as possible for them\u201d, and Leitch broadly welcomed this, saying experts should \u201creally be able to condense those key points into a 25-page report and make it accessible\u201d.<\/p>\n\n\n\n

The panel was cool on the idea of court-appointed experts, with Leitch saying that \u201cthey work better in inquisitorial systems than they do in adversarial systems\u201d, while \u00c7eliktemur and Groehn said that it might result in there being court and party-appointed experts alongside each other, creating confusion.<\/p>\n\n\n\n

Cojoc concluded by coming back to \u201cthe big elephant in this room\u201d,  Kent v Apple<\/em>. \u201cThe evidence is becoming more and more complex,\u201d she said. \u201cWhat the CAT is actually stressing is the fact that evidence should be proportional in order to be sure that it is reliable.\u201d<\/p>\n\n\n\n

Case management<\/strong><\/h3>\n\n\n\n

With so many different moving parts to class actions, the day\u2019s final panel, chaired by Nick Baum, co-founder of payments company Tremendous, looked at the use of technology in case management.<\/p>\n\n\n\n

Eric Miller of AB Data described it as an ongoing process: \u201cSetting up websites, getting telephone lines set up, developing notice plans, disseminating notice, corresponding with class members, [then] throughout the administration, intaking claims, processing claims, calculating damages and distributing funds to class members.\u201d<\/p>\n\n\n\n

Niamh Tattersall of Verita explained that the process in an opt-in claim is to sign up claimants before the claim is issued, whereas in an opt-out that does not begin until after a settlement or judgment.<\/p>\n\n\n\n

Communicating the existence of the claim and the payout to the class is an important and developing part of the role, said Tattersall. \u201cKnowledge is power, so when you have a new topic that you are introducing to an entire society, that is going to come with some hurdles\u201d. That requires a \u201cstrong call to action\u201d and consistent messaging, she continued. \u201cA claims administrator [is] a data management company. So we have to be data-driven. And that means you need to know who the class members are. You need to tailor the notice and communications, and the sign-up process to the class to maximise those sign-ups.\u201d<\/p>\n\n\n\n

The possibility of fraudulent claims is a big concern which is being tackled by identifying IP addresses, fake addresses and formatting errors, \u201cyou look for patterns\u201d in the data, Miller explained.<\/p>\n\n\n\n

There is a balancing act to ensure that eligible claims are not screened out, he said, and Tattersall added that the job of the administrator is \u201cstriking that nice balance, creating a process where fraud mechanisms and protections are in place so that you’re removing the bad actors as much as possible while creating a smooth, streamlined and user-friendly process for class members\u201d.<\/p>\n\n\n\n

Baum added that \u201cthis is certainly a problem that AI is very relevant [for]. You\u2019re dealing with scale; you\u2019re dealing with patterns that need to be detected\u201d. The starting point with AI is the client\u2019s comfort level, said Tattersall, but once those parameters are in place, AI can combat fraud as its strength is organising data points and categories.<\/p>\n\n\n\n

The other concern is data privacy, especially in the UK and EU where the legislation is stringent, \u201cwe have to consider it in every single matter\u201d. Tattersall added.<\/p>\n\n\n\n

On payment options, Miller noted: \u201cMost things are shifting to digital. It\u2019s been that way for quite a while. Fortunately, the class members are getting more comfortable with it.\u201d US class members use a wide range of payment methods, said Baum, \u201cyou need to provide choice, so we\u2019ve seen increased interest in expanding the optionality for recipients\u201d.<\/p>\n\n\n\n

\u201cKnow your class,\u201d agreed Tattersall, and as the process becomes normalised in Europe, user comfort will grow, she concluded.<\/p>\n\n\n\n
