The landscape

Spain is developing a stronger regime to facilitate class actions.

This involves transposing the EU Directive on representative actions into domestic law, a process that still awaits approval from the Spanish Parliament. The proposed law is expected to increase litigation and opportunities for plaintiffs.

Historically, class actions in Spain have been the exception rather than the rule. The standard approach has been to file a large number of individual claims in connection with a similar object. Typical mechanisms have included multiple parallel proceedings, or a joinder by which parties are added to an ongoing lawsuit. Until now, this has primarily involved consumers and retail investors making claims against banks and other financial services firms on the basis that their products were misleadingly promoted to obtain flawed consent. The lack of homogeneity in these claims means Spanish case law remains undeveloped.

By comparison, class actions have been much less frequent and mainly used to achieve injunctive remedies rather than help harmed individuals seek specific redress. Public perception of the mechanism as an avenue to protect their rights has been limited.

Increased litigation is therefore likely in areas of the economy where contracting with consumers is common, and broader consumer protections already apply.

Current developments

The proposed law in Spain will be a cross-cutting regulation. Although legal standing is limited to qualified entities, it is possible to launch a class action in any situation where the collective interest of "consumers" is damaged.

Increased litigation is therefore likely in areas of the economy where contracting with consumers is common, and broader consumer protections already apply. As such, class action claims in other areas such as environment, social and governance or anti-trust law may only take shape in Spain where the damage used to ground the claim represents a contravention of consumer protection regulations.

Sectors that are already characterised by strong public and private accountability mechanisms will likely also provide fertile terrain for follow-on class action litigation. In Spain, regulatory bodies are generally active to protect consumers. Examples include the Spanish Data Protection Agency (Agencia Española de Protección de Datos) and the Antitrust Commission (Comisión Nacional de los Mercados y la Competencia).

Future trends

Spain already has a well-established industry in law firms advising claimants on mass litigation.

It is likely to become a more attractive jurisdiction for plaintiffs seeking to trigger class actions in the future. In particular, cyber risk is a rising concern for companies recognising that failures can have a significant impact on broad groups of customers.

If important aspects of the draft law are finalised as expected, claims that are spurious or not well grounded will be struck out early as part of a rigorous pre-litigation certification phase. However, more plaintiff-friendly features should include the codification of an opt-out system. This is where group members are automatically included in a class action even if they do not actively sign up. Tight controls on third-party litigation funding are also expected to be absent.

The law in Spain with respect to class actions may also evolve as a result of the recent Court of Justice of the European Union judgment of July 2024. This was a landmark claim against CaixaBank for using unfair terms in its consumer contracts. The bank was ordered to cease and desist from using those clauses and to reimburse payments.
