Justice Derek Hartshorn heard submissions from lawyers representing John Simon and the Electoral Commission and reserved his ruling for a later date.
Petitioner and lawyer, Vincent Alois Hamiya, who finished fourth in the election race, is alleging numerous instances of bribery and illegal practice by successful candidate Simon.
He filed the petition on 30 August last year. Simon was declared on 22 July.
The court was addressed on two motions challenging that petition today.
