OTTAWA -- The Conservative party鈥檚 national council president is slamming a petition for a review of Erin O鈥橳oole鈥檚 leadership as 鈥渦nconstitutional.鈥

鈥淲e鈥檙e supposed to be the party of the rule of law, not party of the rule of whim,鈥 Robert Batherson told Evan Solomon on CTV鈥檚 Power Play Tuesday.

Sen. Denise Batters launched a petition Monday calling for a review into Erin O鈥橳oole鈥檚 leadership within six months.

Late Tuesday, O鈥橳oole removed Batters from the Conservative caucus, saying in a news release that he will 鈥渘ot tolerate an individual discrediting and showing a clear lack of respect towards the efforts of the entire Conservative caucus.鈥

Batherson said there is not a provision in the party constitution that would allow a petition or referendum to trigger a leadership review. The senator argues a review will be triggered if five per cent of party membership from at least five provinces sign the petition.
