 In general, tort reform advocates contend that too many of the over 15 million lawsuits filed in the United States each year are "frivolous" lawsuits.The term "frivolous lawsuit" has acquired a broader rhetorical definition in political debates about tort reform, where it is sometimes used by reform advocates to describe legally non-frivolous tort lawsuits that critics believe are without merit, or award high damage awards relative to actual damages.Tort reform advocates argue that the present tort system is too expensive, that meritless lawsuits clog up the courts, that per capita tort costs vary significantly from state to state, and that trial attorneys too often receive an overly large percentage of the punitive damages awarded to plaintiffs in tort cases.
