This is a lawsuit filed by one or more people representing the interests of an entire class of people in litigation "who are similarly situated." Examples might include: all women who have suffered from defective contraceptive devices or breast implants, all those overcharged by a public utility during a particular period, or all those who were underpaid by an employer in violation of the Fair
Labor Standards Act . If a class action is successful, a period of time is given for those who can prove they fit the class to file claims to participate in the judgment amount. Class actions are difficult and expensive to file and follow through, but the results can be helpful to people who could not afford to carry a suit alone. They can force businesses that have caused broad damage to change their practices and/or pay for damages. They often result in high fees for the winning attorneys, although often attorneys do not collect a fee at the beginning of a class action suit but might charge a contingent fee (such as one-third of the final judgment), which, occasionally, can be millions of dollars. Such fees usually require court approval.
