High Quality Content by WIKIPEDIA articles! A strategic lawsuit against public participation (SLAPP) is a lawsuit that is intended to censor, intimidate and silence critics by burdening them with the cost of a legal defense until they abandon their criticism or opposition. The plaintiff does not normally expect to win the lawsuit. The plaintiff's goals are accomplished if the defendant succumbs to fear, intimidation, mounting legal costs or simple exhaustion and abandons the criticism. A SLAPP may also intimidate others from participating in the debate. A SLAPP is often preceded by a legal threat. The acronym was coined in the 1980s by University of Denver professors Penelope Canan and George W. Pring. The term was originally defined as "a lawsuit involving communications made to influence a governmental action or outcome, which resulted in a civil complaint or counterclaim filed against nongovernment individuals or organizations on a substantive issue of some public interest or social significance."
