A Progressive Conservative MLA introduced a new bill to ban floor-crossing in the provincial legislature on Tuesday.
Albert Tory MLA Wayne Steeves tabled the bill that will require a MLA, if they quit a party they were elected with to join another party, to resign and run in a byelection for the new party.
Steeves said his proposed law is a matter of principle.
"I'm a believer that when you run for a political party, you run on their platform and you should stay there,” he said.
“If things happen that you can't stay there, you can sit as an Independent."
Steeves said his bill would not prevent a MLA, who quits a caucus to sit as an Independent, from rejoining the same caucus later.
That's what happened recently with Fundy-River Valley MLA Jim Parrott. Parrott had been kicked out of the Progressive Conservative caucus in 2012 for comments he made about bilingualism and health care, but was welcomed back by the Tories last week.
The Progressive Conservatives were burned by two floor-crossings in 2007. MLAs Wally Stiles and Joan MacAlpine-Stiles bolted the Tories and joined the Liberals.
Stiles was later named minister of natural resources.
