Although Brown retained her seat, Glassie filed a petition against her victory. He alleged that she had effectively bribed voters by covering the charge of a private aircraft to carry voters to vote on Atiu; Brown maintained that this did not constitute an offence.[6] Brown resigned in April 2019 during the process of the petition through the courts and although Glassie was allowed to challenge the election result, this was reversed on appeal.[6][7] Brown's seat was declared vacant in September 2019, triggering another by-election.[8]
