At first glance, two recent judgments from the CAT may give the impression that the new UK class action regime is dead in the water. However, on closer inspection there is much in these judgments that prospective claimants will welcome.
The first decision was in the Pride mobility scooters case (see Tom Coates’ blog here). The CAT made clear that it might have been prepared to grant a collective proceedings order (“CPO”), but on a basis so narrow that the claimants chose not to proceed. In the second decision, Merricks v Mastercard Inc & Ors  CAT 16, the CAT rejected the CPO application, bringing an end to what would have been an extraordinarily ambitious claim—on behalf of 46.2 million people, seeking aggregate damages of approximately £14 billion, for Mastercard’s unlawful setting of fallback multilateral interchange fees in breach of Article 101 TFEU.
Under the new provisions in s.47B of the Competition Act 1998, a CPO application must satisfy the CAT of two criteria. They are, in brief, that (i) the person bringing the proceedings is an appropriate representative of the class of claimants, and (ii) the claims are eligible for inclusion in collective proceedings.
In Merricks, as in Pride, the applicants succeeded on the first criterion but failed on the second. The CAT adopted a relatively liberal approach to certifying the class representative in both cases: a former ombudsman and consumer protection advocate in Merricks (§§93-94), and an advocate for pensioners’ rights in Pride (§§125-139).
The CAT was also satisfied with the litigation funding arrangements in both cases (Pride, §§140-145; Merricks, §§95-140); although it strongly criticised the “impenetrable” drafting of the American-style funding agreement in Merricks, and was only prepared to approve it in light of amendments proposed at the hearing: §§121-127. Prospective claimants will welcome the fact that, in neither Pride nor in Merricks was the CAT unduly concerned by the prospect of a shortfall between the applicants’ costs cover and respondents’ likely costs.
Where both claims failed, however, was on the eligibility criterion. This second criterion is further broken down in rule 80 of the CAT Rules 2015, which provides that claims will be eligible for inclusion in collective proceedings where they (a) are brought on behalf of an identifiable class of persons; (b) raise common issues; and (c) are suitable to be brought in collective proceedings.
In both cases, the CAT was prepared to accept that the claims were brought on behalf of an identifiable class of persons. In Pride that conclusion was uncontroversial, given that the class was defined as “any person who purchased a new Pride mobility scooter other than in the course of a business in the UK between 1 February 2010 and 29 February 2012” (§§5, 85). In Merricks, however, the CAT’s apparent acceptance of the class was no small matter. The class included all individuals who were over 16 years old at the time of the transaction, resident in the UK, and who purchased goods or services from UK businesses which accepted MasterCard cards, at any time over a 16 year period (§1). This included more than 46 million potential claimants; and yet, the CAT was untroubled by the “identifiable class” criterion.
As to the requirement that the claims raise common issues, in both cases the CAT emphasised that the appropriate approach was that followed in Canada, rather than the much stricter approach in the United States (Merricks, §58; Pride, §105). Although only three of the six issues in Merricks could properly be regarded as common, the CAT considered that to be sufficient.
In Pride, the applicant faced the difficulty of proving causation in circumstances where the regulator had focused on a small sample of infringing agreements (“the low-hanging evidential fruit”: §109), and the claimants were time-barred from pursuing anything other than a follow-on claim for the infringement (§110). The CAT’s decision on this issue may well create difficulties for other follow-on vertical infringement claims, but that category of claims is likely to be quite narrow.
In Merricks, the CAT was concerned about the methodology by which the applicant proposed to assess individual losses. The methodology needed to distinguish between three sets of issues: “individuals’ levels of expenditure; the merchants from whom they purchased; and the mix of products which they purchased” (§88). Regrettably, there had been “no attempt to approximate for any of those in the way damages would be paid out” (§88). The CAT observed that the experts’ oral evidence in response to questions from the Tribunal was “considerably more sophisticated and nuanced than that set out, rather briefly, in their Experts’ Report” (§76), but it still could not be satisfied that the damages sought would broadly reflect “the governing principle of damages for breach of competition law”, that is, “restoration of the claimants to the position they would have been in but for the breach” (§88). The judgment sounds a valuable warning to future claimants of the necessity for a detailed and precise methodology for calculating both individual and aggregate losses.
The CAT showed little sympathy for the applicant’s argument that refusing the CPO would result in a vast number of individuals who suffered loss going uncompensated, since there was no realistic prospect of claimants pursuing Mastercard individually. The CAT observed shortly that this was “effectively the position in most cases of widespread consumer loss resulting from competition law infringements” (§91).
The judgments in Pride and Merricks provide important guidance on the CAT’s likely approach to CPOs in future. In spite of the outcomes in both cases, the CAT’s ready acceptance of the proposed class representatives, its flexibility in regard to litigation funding, and its affirmation of the Canadian approach to collective action, are all likely to give heart to prospective claimants. Further, the judgment in Merricks leaves the door open to mass claims in the future, while signalling the heightened importance which expert evidence on calculating losses is likely to assume in such cases.
