Returning the Act candidate as electorate MP activated a quirk in the MMP rules suspending the requirement that parties get at least 5 per cent of the party vote before being eligible to have a proportionate number of MPs.
In 2008, Act scored 3.6 per cent of the total vote but because Mr Hide was returned as MP for Epsom, he was able to bring four list MPs with him. New Zealand First scored 4.1 per cent of the vote, but because it did not win an electorate seat, it got no MPs.
The commission noted the bulk of submissions objected to this "on the grounds that it runs counter to some of the most fundamental principles of the MMP voting system, including that all votes should be of equal value, the primacy of the party vote in determining election outcomes, and fairness of results".
Members of the 1986 Royal Commission that designed the current MMP system "told us they have long regarded the one electorate seat threshold as their one mistake. In their view there are no good reasons to retain it and it should be abolished".
With the Epsom hi-jinks of the past two elections fresh in voters' minds, it's going to be hard for Mr Key to oppose a solution that closes this loop-hole. Particularly when Act is so weak, the chances of National benefiting from this trickery at the next election are minimal.
In its other recommendations, the commission has taken a sensible, don't-rock-the-boat approach. It's proposing the threshold for a party's entry to Parliament be lowered from 5 per cent to the 4 per cent proposed by the commission. The threshold was proposed as a way of, in the commission's words, "discouraging the proliferation of minor and/or extremist groups in the House".
To it, a 5 per cent threshold was "too severe", but parliamentarians of the day ignored the advice and went with 5 per cent. The present review says it "has proved to be a high hurdle", noting that in the last three MMP elections, only the two major parties and the Greens have surmounted it three times, NZ First managing it in 2005 and last year.
It says that 4 per cent is still a significant barrier, noting that in the last election, nine of the 13 parties polled less than 4 per cent of the party vote, and that there have been only three instances of parties receiving between 4 per cent and 5 per cent.
Despite some public clamour against it, the review supports the continuation of the right of electorate candidates to employ the safety net of a place on the party list as well. I agree. MMP is a party-based system, and it makes sense that a party's best and brightest don't get sacrificed in an electorate seat they were never realistically going to win. The talent pool of aspirant MPs is shallow regardless of party. We should be finding ways of encouraging more quality contenders to our Parliament, not driving them away. For the same reason, I support the decision to permit list MPs to continue showing the party flag in byelections.
As for the proposal to abolish the provision for overhang seats, I'm going to have to plead lack of space - and lack of a degree in mathematics. It's all to do with trying to readjust the proportionality of seats in Parliament when, for example, the Maori Party's MP count, because of its electorate seat victories, is out of kilter with its proportion of the total vote. The proposal is to restrict the number of MPs to 120, and work backwards from there to proportionalise the seats.
If the last two elections had been conducted under these new rules, National's MP count would have been down two in 2008 and one last year. It seems unlikely that will get through.
