Does waka jumping put the government in dangerous waters?

As part of Labour’s coalition deal with NZ First they promised to support the so called ‘waka jumping’ bill. The bill would allow a party leader to expel an MP if believe the MP has acted in a way to distort political party proportionality and have the support of 2/3rds of MPs. The bill has been roundly criticised as going against the Bill of Rights Act and seen as undemocratic. Lachlan spoke with Professor Claudia Geiringer from Victoria University about the bill and the problems around it.
