Rodney Hide writes in the HoS:
Then we had the constitutional point. That no one, including the Prime Minister, could fire Gilmore forthwith was presented as a failing of our Parliamentary system. He was a list MP. He had done wrong. He should be fired.
I am not so sure those calling for the summary power to dismiss list MPs would appreciate the consequences.
I had two list MPs in my caucus forever trying to dispatch me. If I had been able to fire them, I would have. And I would still be there. But that’s hardly a satisfactory outcome for anyone.
I agree with Rodney that a party should not be able to sack a List MP. It would turn them even more into creatures of the party.
It would be a power too open to abuse by party leaders to get rid of MPs that challenge their authority.
