Portugal. The Class Actions Law Review
The only collective action procedure available in Portugal that is similar to common law’s class action is the ‘popular action’.
In accordance with Article 52 of the Portuguese Constitution, every citizen has the right to individually, or jointly with others, submit petitions, representations, claims or complaints to defend: their rights; the Constitution; the laws or the general interest of sovereign entities; self-government bodies of the autonomous regions; or any authority. They also have the right to be informed of the outcome of any petition, representation, claim or complaint within a reasonable time frame.
All citizens with political and civil rights have the right to popular action, independently or through associations or foundations incorporated to defend relevant diffuse interests.
