Strategic litigation, also known as impact litigation, is the practice of bringing lawsuits intended to affect societal change.[2][3] Impact litigation cases may be class action lawsuits or individual claims with broader significance,[1] and may rely on statutory law arguments or on constitutional claims.[4] Such litigation has been widely and successfully used to influence public policy, especially by left-leaning groups, and often attracts significant media attention.[2] One prominent instance of this practice is Brown v. Board of Education.[1]
