A legal challenge against the election of Treasurer Josh Frydenberg and embattled Liberal MP Gladys Liu is expected back in court.
The fight, sparked by controversial Chinese-language posters, has been sent to the Federal Court amid a bid to get the Liberal Party to hand over information relating to the case.
Mr Frydenberg and Ms Liu are being challenged over alleged illegal conduct during the election campaign, after Liberal-authorised signs were displayed at Kooyong and Chisholm polling booths on election day in May.
The Chinese-language signs were in the Australian Electoral Commission's official colours of purple and white, had no Liberal branding and didn't refer to Liberal candidates by name or policies.

Failed Kooyong candidate Oliver Yates is spearheading the case again Mr Frydenberg, while climate campaigner Leslie Hall is challenging the election of Ms Liu, who is also under fire for previous links to Chinese Communist Party-associated community organisations.
During an earlier High Court hearing about the polling day signs, lawyers for Mr Yates and Ms Hall asked for orders to get the Liberals to hand over certain information.
Justice Michelle Gordon believed a Federal Court trial could better grapple with such orders.
An administrative hearing is set down for the Federal Court in Melbourne on Tuesday afternoon.
Opposition Leader Anthony Albanese said the court will make its judgment but it's crucial Australia's democracy is cherished and not manipulated.
"The information written in Chinese, Mandarin, on those signs, quite clearly could be viewed to be misleading," he told reporters in Bendigo on Tuesday.
