Ditchburn v Divisional Returning Officer (Qld)

The case of *Ditchburn v Divisional Returning Officer (Qld)* concerned a petition brought before Hayne J in the Court of Disputed Returns, challenging the validity of an election for the House of Representatives. The petitioner, Ditchburn, disputed the election's outcome, raising fundamental questions about the nature of the Australian electoral system.

The central legal issues before the Court were whether the preferential voting system employed in federal elections constituted plural voting, and consequently, whether members of the House of Representatives were "directly chosen by the people" as required by the Australian Constitution. The petitioner argued that the preferential system, by allowing voters to express preferences beyond their first choice, effectively granted some voters more influence than others, thereby undermining the principle of one vote, one value.

Hayne J dismissed the petition, finding that the preferential voting system does not amount to plural voting. His Honour reasoned that each elector is entitled to cast only one vote, and that vote is counted according to the voter's expressed preferences. The Court held that the preferential system is a method of ensuring that the candidate elected has the support of a majority of voters, and that this method is consistent with the constitutional requirement that members of the House of Representatives be "directly chosen by the people". The Court concluded that the preferential system is a valid means of achieving direct choice by the electorate.

Consequently, the petition was dismissed, and the petitioner was ordered to pay the costs of the respondent and the Australian Electoral Commission.
