Josh Frydenberg and Gladys Liu are facing High Court challenges to their election wins, after questions were raised about Minister Frydenberg’s citizenship and the Liberal Party's campaign conduct.
Oliver Yates, who unsuccessfully contested the Victorian seat of Kooyong against Mr Frydenberg, is arguing the Kooyong election was affected by illegal conduct committed by the Liberal Party, to the knowledge of both Liberal candidates.
The Liberals authorised a sign in the AEC’s official colours of purple and white without Liberal branding, and it was in Chinese language saying the right way to vote was to put the Liberal Party first.
