Saturday's referendum on the electoral system did more than just embed MMP, subject to the tinkering recommended by an Electoral Commission review. It also, by implication, enhanced the case for the term of Parliament to be increased from three to four years.
The argument against this has always been that in a country with few constitutional restraints on the power of the Executive, a short term affords the electorate one strong means of restraint.
If proportional representation promised to be an equally effective safeguard, its popularity had yet to be confirmed. Now, with the substantiation of MMP's broad acceptance, the time is right to reconsider a four-year term.
The thought is not new. In the most recent referendum on the subject, in 1990, 69.3 per cent of those who voted opposed the notion. That rejection must, however, be placed in context. It was held at the tail-end of a two-term Labour Government whose disdain for the public view led eventually to the introduction of MMP.
Politicians were held in particularly low esteem, and people were in no mood to endorse a device that would make governments even less responsive to the electorate.
