Bill summary
What changes
The bill creates a new legal hurdle for defamation lawsuits filed by individuals accused of sexual or domestic violence against their alleged victims.
Who is affected
Alleged perpetrators of sexual/domestic misconduct, victims/survivors, and the civil court system.
Requirements and enforcement
Plaintiffs must plead specific, verifiable facts (impossibility or public retraction) to proceed with a defamation claim; general allegations are insufficient.
Costs and funding
Less than $10,000 in fiscal impact; however, individual litigants may face significant financial exposure from treble damages and attorney fees.
When it takes effect
Takes effect January 1, 2026.
Potential benefits
Provides strong protection for survivors of sexual/domestic violence against 'SLAPP'-style retaliatory legal actions; mandates financial penalties for frivolous suits.
Risks and tradeoffs
Potential violation of due process by restricting access to the courts; high bar for proving defamation may capture valid claims; significant financial risk for potential plaintiffs.
What is still unknown
The exact threshold the courts will use to determine what constitutes 'factual impossibility' and how this interacts with existing defamation discovery rules.
