Moira Deeming is doing what she does best: picking a massive fight. The controversial Victorian Liberal upper house MP just launched an 11th-hour Supreme Court lawsuit against her own state party president, Brian Loughnane.
The move is a frantic attempt to block an extraordinary state executive meeting designed to strip away her preselection. It’s a high-stakes legal gamble that comes less than five months before Victoria’s November state election. If you think this is just another minor political spat, you’re missing the bigger picture. This is a battle for political survival that could tear the Victorian Liberal Party apart right when they need unity the most.
The Assault Claim That Started the New War
To understand why Deeming is suing her own party president, you have to look at the explosive incident that triggered this latest round of infighting.
In May, Deeming lodged a formal police complaint against former Liberal leader Matthew Guy. She alleged that Guy had assaulted her by grabbing her "violently" in a headlock during a gala dinner. It was a massive accusation that immediately sent shockwaves through the party.
The problem? Victoria Police investigated the claim, reviewed the venue's CCTV footage, and flatly announced that "there was no offence detected."
According to Deeming’s lawyer, Tim Houweling, the CCTV footage shows Guy placing his hand on Deeming's upper back or shoulder area to pull her in to say something, a gesture he then repeated with another man at the table. Houweling argued that Guy maintained his grip as Deeming tried to pull away, causing her "fear and confusion."
Deeming later backtracked slightly, claiming she misunderstood what the word "headlock" actually meant. But the damage was done. Guy was furious, demanding a public apology and declaring his family name isn't a political toy.
"There was no ambiguity. I did not do what was alleged. The CCTV proves this. It did from the start, and Victoria Police agree," Guy said.
Despite immense pressure from the very top of the party, Deeming refused to apologise. That refusal is exactly what pushed the Liberal leadership to its breaking point.
Inside the Supreme Court Showdown
Because Deeming wouldn't issue an unqualified apology to Guy, the Victorian Liberal state executive scheduled a meeting to decide her future. The party constitution gives the executive the power to disendorse candidates who bring the party into disrepute.
Instead of waiting around to be pushed off the ticket, Deeming went on the offensive.
Her legal challenge against Brian Loughnane targets the procedural fairness of the review process. Her team argues that the party's push to revoke her preselection lacks proper notice and fairness. By filing this lawsuit in the Victorian Supreme Court, Deeming is attempting to freeze the party's machinery before they can vote her out.
It's an incredibly rare move. Political parties usually enjoy wide legal latitude to manage their own internal rules and preselection tickets. Taking a political party to court over its own internal processes is an uphill battle, but Deeming has a track record of winning when people count her out.
Why the Liberals are Desperate to Stop the Drama
The timing of this lawsuit couldn't be worse for the Victorian Coalition. With the state election locked in for November 2026, Opposition Leader Jess Wilson is trying to present a stable alternative to Jacinta Allan’s Labor government. Instead, the public is watching a relentless reality TV show of internal factional warfare.
Political scientist Zareh Ghazarian noted that this is a critical point for the leadership. The scandal has already hobbled the party significantly and taken up vital political coverage.
Even minor parties want nothing to do with the fallout. One Nation leader Pauline Hanson publicly shut the door on offering Deeming a spot, citing her refusal to apologize to a colleague as a lack of integrity.
A History of Burning Bridges
This isn't Deeming's first time dragging her party into a courtroom. She's a polarizing figure who has consistently chosen litigation over compromise.
- The 2023 Rally: Deeming was suspended and later expelled from the parliamentary Liberal party room after speaking at a "Let Women Speak" rally that was gatecrashed by neo-Nazis.
- The Defamation Win: She sued then-leader John Pesutto for defamation, claiming he falsely painted her as a Nazi sympathiser.
- The Leadership Fall: In late 2024, the Federal Court awarded her $300,000 in damages. That legal victory heavily contributed to Pesutto losing the Liberal leadership.
Deeming knows how to use the courts as a weapon against her political enemies. She’s betting that the threat of more legal bills and public embarrassment will force the party executive to back down.
What Happens Next
If the Supreme Court grants Deeming an injunction, it will delay the state executive's ability to dump her from the Western Metropolitan Region ticket. That buys her time to rally her conservative base, which views her as a warrior for women's rights and a victim of party elites.
If the court rejects her application, the state executive will almost certainly move to disendorse her immediately. Deeming has already hinted that she won't go quietly and could run as an independent. A rogue independent campaign from Deeming would bleed conservative votes away from the Liberals in a crucial region.
For everyday voters who want to know how this ends, the immediate step is watching the Supreme Court's decision on the injunction. If the court blocks the party meeting, expect weeks of bitter legal gridlock. If the court clears the way, the Liberal party will cut ties, and Deeming will likely launch a scorched-earth independent campaign that will haunt the party all the way to November.
Embattled MP’s future unclear after refusing to apologise for assault claim provides a breakdown of the political fallout inside the Victorian Liberal Party room following Deeming's refusal to issue an apology.
