You could get SLAPP(ed) for signing it if Ms Morton decides to show her bad side. Which she rarely does.
Retaliatory lawsuits intended to silence, intimidate, or punish those who have used public forums to speak, petition, or otherwise move for government action on an issue.
The term strategic lawsuits against public participation, known by the acronym SLAPPs, applies to a variety of different types of lawsuits, including those claiming libel, defamation, business interference, or conspiracy. The term was coined by Professors George W. Pring and Penelope Canan of the University of Denver, who began to study this form of litigation in 1984. Pring and Canan define SLAPPs using four criteria: "[SLAPPs] (1) involve communications made to influence a government action or outcome, (2) which result in civil lawsuits (complaints, counterclaims, or cross-claims), (3) filed against non-governmental individuals or groups (4) on a substantive issue of some public interest or social significance."
In a typical SLAPP, an individual or citizens' group—the target (using Pring and Canan's terminology), or defendant—is sued by the filer, or plaintiff, for alleged wrongdoing simply because that individual or group has used constitutionally protected rights to persuade the government to take a particular course of action. SLAPPs have been directed against individuals and groups that have spoken in public forums on a wide variety of issues, particularly against real estate development, the actions of public officials, environmental damage or Pollution, and unwanted land use. They have also been used against those who have worked publicly for the rights of consumers, workers, women, minorities, and others. SLAPP defendants have been sued for apparently lawful actions such as circulating a petition, writing to a local newspaper, speaking at a public meeting, reporting violations of the law, or participating in a peaceful demonstration.
