Illinois Statutes Chapter 735. Civil Procedure § 110/15. Applicability

§ 15. Applicability. This Act applies to any motion to dispose of a claim in a judicial proceeding on the grounds that the claim is based on, relates to, or is in response to any act or acts of the moving party in furtherance of the moving party's rights of petition, speech, association, or to otherwise participate in government.

Acts in furtherance of the constitutional rights to petition, speech, association, and participation in government are immune from liability, regardless of intent or purpose, except when not genuinely aimed at procuring favorable government action, result, or outcome.
