74.Section 15 provides that if a recall petition is successful, the MP’s seat becomes vacant when the petition officer notifies the Speaker that the recall petition was successful (subsection (1)). However, this does not apply if, before the notice is given, the MP’s seat is already vacated as result of the MP’s disqualification, death, or for any other reason (subsection (2)). Subsection (1) is subject to regulations under section 18 about questioning the outcome of the petition (subsection (3)).
