What Is a Class Action Lawsuit?

A class action is a type of lawsuit where one or a few plaintiffs (called "class representatives") sue on behalf of a larger group of people ("the class") who all suffered similar harm from the same defendant.

When class actions are appropriate:

Many people were harmed by the same conduct.

Individual claims are too small to justify separate lawsuits.

Common questions of law or fact exist across all claims.

The class representatives' claims are typical of the class.

How it works:

Filing — An attorney files a complaint on behalf of the proposed class.

Certification — The court decides whether the case meets the requirements for class treatment (numerosity, commonality, typicality, adequacy).

Notice — Class members are notified of the lawsuit and their right to opt out.

Discovery and litigation — The case proceeds through evidence gathering and motions.

Settlement or trial — Most class actions settle. Settlements must be approved by the court as fair and adequate.

Distribution — Settlement funds are distributed to class members.

Common types:

Consumer fraud (defective products, deceptive practices)

Securities fraud

Employment discrimination

Data breaches and privacy violations

Environmental contamination

Antitrust violations

Opting out. You can usually opt out of a class action to pursue your own lawsuit, but you must do so before the deadline.

Criticisms. Critics note that class members often receive small payments while attorneys earn large fees. However, class actions remain an important tool for holding corporations accountable.
