Mark Latham appeals a $140,000 defamation ruling over a 2023 tweet accusing gay MP Alex Greenwich of explicit acts, calling it a response to an insult.

Mark Latham is appealing a $140,000 defamation ruling over a 2023 tweet describing gay MP Alex Greenwich engaging in explicit sexual acts, calling it a response to Greenwich’s insult and not defamatory. Latham claims no reputational harm occurred and that the post referenced common conduct. Greenwich disputes this, calling the appeal incoherent and asserting the tweet vilified his private life and caused harm, including homophobic backlash. A three-day Federal Court hearing begins November 25, with Greenwich seeking higher damages. A separate vilification case is also pending. The dispute follows violent protests in March 2023 after Latham spoke at a Sydney church.
