Sean Buckley vs. Police Informant

Since 2020 Buckley has been subject to legal proceedings initiated by Jennifer Cole, who falsely accused him of stalking and assault. On the 7 August 2025 at Melbourne Magistrates Court, the police prosecutor, in front of Magistrate Malcolm Thomas withdrew all charges, and Buckley's solicitor Martin Amad stated "It reflects what he has said to his lawyers for the last five years that he is an innocent man. Of course it's a relief, and he thanks the justice system for obviously coming through with this decision."
