I'm not aware of it. I know that the German system is federal system, and they have a provision of overhang seats. In the New Zealand context, one of the recommendations that the Electoral Commission made in 2012 to the New Zealand Parliament was that the one-seat threshold, which currently exists, should be abolished. If that recommendation were to be adopted, one of the consequences would be that the number of overhang seats might increase to an unacceptable level. We therefore recommended that provision for overhangs be removed. Our advice, on the analysis that we did, was that the impact on proportionality would be minor.
