Meaning and Definition

A lawsuit filed by a representative on behalf of a large group of people who have suffered similar harm or loss.

Any collective action or proceeding undertaken by a group sharing common interests or goals, particularly within a legal or organisational framework.

Dialectal Variation

British vs American Usage

Differences

Concept and term are identical and widely understood. The procedural rules for initiating and certifying a class action differ between jurisdictions (e.g., England & Wales vs. US Federal Rules). The US has a much more active class action litigation culture.

Connotations

In the US: a common tool for consumer protection and corporate accountability, but also sometimes viewed as exploitative by businesses. In the UK: a more specialised, less frequent legal mechanism, often called a 'group litigation order'.

Frequency

Significantly higher frequency in American English due to its central role in the US legal system. In British English, it is a specialised legal term with lower public discourse frequency.

FAQ

Frequently Asked Questions

Yes, one or a few named plaintiffs can file a lawsuit seeking to represent a larger 'class' of similarly situated people. The court must later 'certify' the class for it to proceed as a true class action.

Typically, no. Class action lawyers usually work on a 'contingency fee' basis, taking a percentage of the final settlement or award. Plaintiffs are not usually charged upfront.

If you are a member of a certified class but wish to pursue your own independent lawsuit, you must formally 'opt out' by a deadline. If you do nothing, you are automatically included in the class and bound by its result.
