Plaintiff-Side Class Action Litigation
A class action lawsuit is used when a number of people suffer the same or similar injuries as a result of the same unlawful conduct by a defendant or group of defendants.
Because many individual injuries are not worth enough to support a lawsuit, class actions allow those harmed to band together and bring a case against some of the largest companies in the world.
Also, filing as a class allows for the consolidation of class action attorneys, evidence, witnesses, and other aspects of litigation to make the lawsuit more efficient.
Bringing a case as a class action also allows for the consolidation of class action attorneys, evidence, witnesses, and other aspects of litigation to make the lawsuit more efficient.
The special federal rules governing class actions are found in the Federal Rule of Civil Procedure 23.
Many states also have their own rules governing class actions filed in state court, most of which are modeled directly on the federal class action rules.
Facing a powerful company or institution on your own can be overwhelming, especially when the damage affects many people just like you. You deserve powerful representation that understands the weight of what you’re going through and the importance of holding defendants accountable.
