a conscience vote on all matters, page-19

If a politician wants to vote according to his/her conscience then they can always run as an Independant. If they want the support of a major party at election time then they are obliged to vote upon party lines for the most part. If the electorate wants an independant member then they can vote for the independant, but who determines what the majority of the voters views are?
Having said that, congratulations to those who wouldn't support the refugee bill.
