AB 431 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: special motions to strike strategic lawsuits against public participation. (FE)

AB 431 creates a "special motion to strike" process to quickly dismiss lawsuits that target individuals or groups for speaking out on public issues, such as criticizing government actions or participating in public debates. If a plaintiff sues for speech protected under free speech or petition rights, the defendant can file this motion; the court will dismiss the case unless the plaintiff proves they are likely to win. If the motion succeeds, the winning defendant typically recovers attorney fees, unless the motion was frivolous or delayed the case. This bill directly affects people engaging in public discourse, including activists, journalists, and community members, by making it harder for opponents to use lawsuits to silence them.
