Petitioner in the Southern Highlands Regional seat, Joseph Kobol, went before the Supreme Court with an application seeking leave to file for review.
A ruling will be given at a later date.
Justice Derek Hartshorn, sitting as a single Supreme Court judge, today heard submission from lawyers representing Kobol, the Electoral Commission and Governor William Powi.
Kobol is asking the Supreme Court to grant him leave to file a review into the dismissal of his petition in the National Court on June 14 after it was found to be incompetent.
