What is Class Action?

A type of lawsuit in which one or more plaintiffs file and pursue a case on behalf of a larger group of people who have similar claims against the same defendant.

Understanding Class Action

Class actions are appropriate when individual claims are too small to justify separate lawsuits but collectively represent significant harm. The court must certify the class by finding that there are enough members, common legal questions, the representatives are typical of the class, and they will adequately protect the class's interests. Class members who do not opt out are bound by the outcome.

Examples

  • 3Data breach victims joining a class action against a company that failed to protect their information
