A more thorough explanation:

A named plaintiff is a person who sues on behalf of a group of plaintiffs in a class action. They are also known as a class representative. This person represents the interests of the entire group in court.

In a class action lawsuit against a company for selling defective products, one person is chosen as the named plaintiff to represent all the other people who bought the product. The named plaintiff will work with the lawyers to present the case in court and negotiate a settlement or judgment.

This example illustrates how a named plaintiff is chosen to represent a group of people in a legal case. They are responsible for making decisions on behalf of the group and communicating with the lawyers.
