Re Parry; Re Lambie

The High Court of Australia, sitting as the Court of Disputed Returns, considered questions referred concerning the eligibility of Mr Stephen Parry and Ms Jacqui Lambie to sit as Senators. The proceedings also involved a declaration sought by the Commonwealth Attorney-General that Mr Richard Colbeck was duly elected as a Senator for Tasmania. The core of the dispute revolved around the distribution of votes in the Tasmanian Senate election following the disqualification of Mr Parry and Ms Lambie, and the potential impact of this on the election of other candidates, particularly Mr Colbeck.

The legal issues before the Court included determining the correct method for distributing votes in the Senate election, specifically the calculation of surplus votes and their transfer value. The Court was required to consider whether the exclusion of certain candidates, such as Mr Martin (a candidate from the Jacqui Lambie Network), could theoretically alter the outcome of the election and affect the declaration of Mr Colbeck as duly elected. This involved examining the mathematical implications of vote transfers and the potential for a different candidate to be elected if the distribution process were simulated with excluded candidates.

The Court heard submissions on the mechanics of vote distribution under the Commonwealth Electoral Act 1918 (Cth), including the calculation of transfer values for surplus votes. The Solicitor-General for the Commonwealth argued that Mr Colbeck's election was secure, as the number of votes he received and the surplus distributed to him were such that even a theoretical alteration in vote transfers due to the exclusion of other candidates would not be sufficient to disturb his position. This was based on the calculation that the transfer value of votes could only increase, not decrease, if Mr Martin's votes were redistributed, thereby making it mathematically improbable that Mr Colbeck's election would be affected. The Court considered the possibility of running simulations to definitively resolve any lingering doubts about the election outcome.
