Le registre international

Whilst the majority of the countries having adopted a sort of collective redress mechanism have not yet adopted a Register, some countries have done so.
The said Registers have a major publicity role since they, namely and according to the systems:
 • allow claimants to know if a lawsuit has already been filed in a particular field or against a given party (and built a legal strategy thereof)
• allow potential claimants to contest the representativity of the one having brought the action, and/or potentially cooperate with the latter for the success of the proceedings
• allow potential members of the class to know they are represented and then potentially recover the amounts granted on their behalf
Some of those Registers are the following ones:

United Kingdom

At least two registers coexist in the United Kingdom:

1. The Competition Appeal Tribunal

The United Kingdom Competition Appeal Tribunal is a specialist judicial body with cross-disciplinary expertise in law, economics, business and accountancy which hears and decides cases involving competition or economic regulatory issues.

It contains namely collective cases brought and decisions handed within the Competition private enforcement scope on an opt-in or on an opt-out basis, according to Section 47b Competition Act.

2. The General Litigation Order

The United Kingdom lists and informs about Group actions “which give rise to common or related issues of fact or law” and engaged according to r19.10 of the Civil Procedure Rules.

Representative actions are not registered as such. See for instance TikTok the case.

Popular actions do not have a special register in Portugal. Civil actions are published on the Citius website, in the distribution of new cases section and during this short period (a few months only). 


In Canada, collective actions are registered at the Canadian Bar Association, with a full list available here.

In Quebec, they are registered in the Registre des actions collectives, with a full list available here.
