Collective redress is the umbrella term, used mainly in Europe, for court procedures that allow a single representative to seek a remedy for a large group of people who suffered the same kind of harm from the same company. The remedy can be an order to stop the conduct, known as an injunction, or compensation, known as redress. The mechanism exists because many consumer and data harms are small for each person and large in total. A user who lost 50 euros to an unlawful fee will rarely sue a multinational. Bundled together, millions of such claims become a case worth bringing.

In the European Union, the dominant framework is Directive (EU) 2020/1828, the Representative Actions Directive, which obliges every member state to offer at least one collective procedure for consumer claims. In the United Kingdom, the best-known channel is the opt-out collective proceedings regime at the Competition Appeal Tribunal (CAT) in London. Both differ deliberately from the American class action.

How collective redress works

Under the EU directive, only a qualified entity can sue. This is typically a consumer association or a non-profit such as the privacy group noyb. For cross-border cases, Article 4(3) sets six conditions: the entity must be a legal person under national law, show 12 months of public activity protecting consumers, be non-profit, not be insolvent, be independent from traders and funders with an economic interest, and publish information on its funding and structure. Member states had to send the Commission their lists of cross-border entities by December 26, 2023.

The directive covers breaches of the EU laws listed in its Annex I, which ran to 66 instruments when adopted. The General Data Protection Regulation (GDPR) is item 56, alongside the Consumer Rights Directive and the digital content directive. Later laws, including the Digital Services Act and the Digital Markets Act, extended that list.

Two kinds of order are available. Injunctive measures under Article 8 stop or prohibit a practice and do not require proof of individual loss. Redress measures under Article 9 deliver compensation, repair, replacement, price reduction or refunds. Each country decides whether consumers must opt in (actively join the case) or are included automatically unless they opt out. One rule is fixed: consumers not habitually resident in the country of the court must opt in to be bound. Most member states chose opt-in; the Netherlands and Portugal use opt-out.

Safeguards against abuse are written into the text. Article 12 applies loser pays, so the losing side covers the winner's costs, while individual consumers generally do not. Article 10 lets courts check third-party funding and reject funders that could divert the action from consumers' interests. Recital 42 states that the directive "should not make it possible to impose punitive damages".

The UK system works differently. Since October 1, 2015, section 47B of the Competition Act 1998 has allowed a class representative, often a special purpose company led by an academic or former official, to file a claim for breaches of competition law. The CAT must issue a collective proceedings order (CPO) before the case can proceed, testing whether the representative is suitable and whether the claims fit collective treatment. The tribunal then decides opt-in or opt-out. Settlements need CAT approval under section 49A.

A worked example shows how the money flows. In Merricks v Mastercard, brought for about 44 million UK adults, the claim was originally put at about GBP 14 billion. It settled for GBP 200 million, roughly 1.4% of that figure, according to a Divisional Court judgment of June 10, 2026. Consumers received a GBP 100 million pot, with a minimum payment of GBP 45 per claimant and an expected take-up of about 5%. The funder, Innsworth Capital, recovered expenditure of at least GBP 41 million plus a profit of about GBP 22.5 million.

Origin and evolution

Europe's approach grew out of injunction-only rules. The Injunctions Directive of 1998, codified as Directive 2009/22/EC, let consumer bodies stop unlawful practices but not claim damages. On June 11, 2013, the Commission issued Recommendation 2013/396/EU, inviting member states to adopt compensatory collective procedures built on opt-in, non-profit representatives and a ban on punitive damages. After the diesel emissions scandal, the Commission proposed binding rules as part of its "New Deal for Consumers" in April 2018. The directive was adopted on November 25, 2020, published on December 4, 2020, and had to be transposed by December 25, 2022 and applied from June 25, 2023.

National regimes moved at different speeds. The Netherlands introduced its WAMCA law on January 1, 2020, adding damages and an opt-out for Dutch residents to its older foundation model. Germany's Consumer Rights Enforcement Act (VDuG) took effect on October 13, 2023, creating its first damages action for consumers, open where at least 50 consumers may be affected. Spain was still the only member state without full transposition as of June 2026, according to BEUC, the European consumer organisation; the Commission sent it a reasoned opinion on April 29, 2026.

The UK's opt-out regime arrived through the Consumer Rights Act 2015. It stalled until the Supreme Court's Merricks ruling of December 2020 lowered the bar for certification. Lloyd v Google, in November 2021, blocked a representative claim for about 4 million iPhone users under the general court rules. PACCAR, in July 2023, held that litigation funding agreements paid as a share of damages were damages-based agreements, unsettling funding contracts across the CAT.

Why it matters for the marketing community

For advertisers, publishers and platforms, collective redress has turned privacy and competition disputes into balance-sheet risk. The UK tribunal on August 5, 2026 certified an opt-out claim for UK advertisers against Google, valued by the claimant's economist at about GBP 5 billion for search advertising bought between January 1, 2011 and April 15, 2025. Here advertisers are the claimants, not the defendants.

App economics are under the same pressure. The CAT found in October 2025 that Apple abused its dominant position in app markets, in a claim for about 36 million users valued at GBP 1.184 billion to GBP 2.237 billion. Google agreed a GBP 260 million settlement with UK app developers, approved on September 16, 2026, with about GBP 160 million for developers and GBP 100 million for the funder, insurers and lawyers.

Ad tech data practices are the other front. In Ireland, the Irish Council for Civil Liberties won permission on May 26, 2025 to bring the first class action against Microsoft over real-time bidding data, covering users of Xandr technology. noyb gained qualified-entity status for EU-wide collective cases in Austria on December 2, 2024 and in Ireland in October 2024, and put typical non-material damages at 100 to 1,000 euros per user.

Limitations and disputes

The central dispute is who benefits. Funders argue they make claims possible. Critics point to settlements such as Merricks, where consumers shared a pot worth a fraction of the headline claim and the funder's return was ring-fenced from take-up. In the Google developer settlement, stakeholder claims exceeded their pot by about GBP 15 million as of July 31, 2026.

Take-up is a second weakness. The CAT expected about 5% of Merricks class members to claim. Angeion Group projected 8% to 15% take-up by number in the Google developer case. Low participation leaves money undistributed.

Europe's model draws criticism from the opposite side. Opt-in procedures, loser-pays costs and non-profit-only standing limit the number of cases, and consumer groups say redress actions remain rare outside the Netherlands. A Dutch practitioner review of five years of WAMCA case law described the record on large-scale damages as "modest so far". Jurisdiction also remains contested. The Court of Justice of the EU ruled on December 2, 2025 that a Dutch court could hear a representative action covering all App Store NL users without locating each user's damage, a decision Apple had resisted.

Recent developments

Reform is under way in London. On July 17, 2026, the Department for Business and Trade opened a consultation, closed on September 25, proposing to codify the stricter certification test from the Supreme Court's Evans v Barclays ruling, allow damages-based agreements, let the CAT compel mediation and charge fees linked to claim value, according to Jones Day.

In the EU, privacy cases are multiplying. noyb on August 26, 2026 threatened an injunction against SCHUFA over a credit database covering 69 million people, with a possible damages action to follow. In the Netherlands, SOMI filed against Snapchat on June 9, 2026, seeking up to 1,000 euros per user, and the Privacy Collective sued AppLovin on May 21, 2026 over data on at least 8.5 million people, according to BEUC. The directive's first formal evaluation cannot come before June 26, 2028.

Summary

  • Who: Qualified entities such as consumer associations and noyb in the EU, class representatives and their funders in the UK, the courts that certify and supervise the claims, and the companies sued, increasingly platforms and ad tech firms.
  • What: Procedures letting one representative seek injunctions or compensation for many people harmed by the same conduct, with safeguards on funding, costs and damages that set them apart from US class actions.
  • When: EU principles date to June 2013; the binding directive was adopted on November 25, 2020 and applied from June 25, 2023; the UK opt-out regime began on October 1, 2015.
  • Where: All EU member states, with the Netherlands, Portugal and Germany prominent, and the Competition Appeal Tribunal in London.
  • Why: Individual losses are often too small to litigate; aggregation makes enforcement against large companies economically viable.
