Guerin v O'Doherty (Approved) [2026] IECA 48 (26 March 2026)

The Court of Appeal held that the defendant failed to establish that the proceedings disclosed no reasonable cause of action, were bound to fail, or amounted to an abuse of process. The issues of privilege and public interest defence are factual and must be determined by a jury. The defendant's arguments regarding SLAPP, fair trial, and bias were unsupported and inconsistent. The High Court correctly applied the legal test and exercised its discretion appropriately. The appeal was dismissed.
