Strategic lawsuit against public participation
Strategic lawsuits against public participation (also known as SLAPP suits or intimidation lawsuits), or strategic litigation against public participation, are lawsuits intended to censor, intimidate, and silence critics by burdening them with the cost of a legal defense until they abandon their criticism or opposition. In a typical SLAPP, the plaintiff does not normally expect to win the lawsuit.
