A Liberal MP has launched an 11th-hour court challenge against her own party before a meeting to decide her fate after she made an assault allegation against a former leader.

Moira Deeming has lodged a legal action against Victorian Liberal party state president, Brian Loughnane, which is listed to be heard in the Victorian supreme court on Friday morning.

The latest round of Liberal infighting comes less than five months out from the 28 November state election, with party executives, including Loughnane, planning to meet on Friday evening to determine Deeming’s candidacy.

The upper house MP had made a police complaint against a colleague, Matthew Guy, alleging that he had assaulted her by grabbing her “violently” in a headlock at a gala dinner on 23 May.

Victoria police investigated and found “there was no offence detected”.

Guy has demanded a public apology from Deeming. “There was no ambiguity,” he said. “I did not do what was alleged. The CCTV proves this. It did from the start, and Victoria Police agree.”

Deeming has since claimed she misunderstood the meaning of headlock but has refused to apologise.

She has been invited to the state executive meeting to tell her side of the story but whether she attends is yet to be seen.

The opposition leader, Jess Wilson, on Thursday refused to answer questions about the process but told reporters Guy’s reputation had been harmed and she had directly asked Deeming to apologise.

“I think he deserves an apology,” she said. “That is the right thing to do, and Moira has decided that’s not the case. And now the state executive will meet.”

Pauline Hanson has declared she would not offer Deeming a position at One Nation. The senator said Deeming’s refusal to apologise to Guy showed the first-term MP could not “admit that she got it wrong”.

“You don’t do that to your fellow colleagues,” she told 3AW radio.

The scandal is yet another flare-up of what the public would see as disunity and disorganisation in the party, said a Monash University political scientist, Zareh Ghazarian.

“This is arguably the most critical point for the Liberal leadership right now to clear their internal problems,” he said. “This has to be resolved as quickly as possible because it’s already taken up a lot of political coverage … it has hobbled the party significantly.”

Deeming’s lawyer Tim Houweling said his client’s complaint had been made “honestly, in good faith and only as a matter of last resort”.

He referred to CCTV footage that shows Guy sitting at a table and talking with Deeming and another man. The former leader appears to place his hand on Deeming’s upper back or shoulder area and pull her in to say something before doing a similar gesture with the man.

The lawyer said Guy had maintained a grip as Deeming tried to pull away and this physical contact was “unexpected, unwelcome, physically painful and caused her to feel fear and confusion”.

Deeming successfully sued the former leader John Pesutto for defamation when he wrongly implied she was associated with neo-Nazis after they gatecrashed a rally at parliament she attended.
