Ruddick v Commonwealth of Australia

The plaintiff, Mr Ruddick, brought proceedings against the defendant, the Commonwealth of Australia, before the High Court of Australia. The dispute concerned the finalisation of a special case, which required agreement on certain factual assertions to determine the legal issues. The parties were seeking to resolve outstanding disagreements regarding specific paragraphs within the special case document, which were intended to provide the factual foundation for the Court's determination of the constitutional question.

The central legal issues before the Court were whether certain proposed factual assertions, specifically relating to paragraphs 58, 59, and 73 of the special case, should be included. The plaintiff contended for their inclusion, arguing they were necessary to establish voter confusion arising from the relative positioning of political parties on ballot papers. The Commonwealth, while not necessarily disputing the raw data presented in some of these paragraphs, resisted their inclusion on the basis that they would introduce alternative inferences that would "muddy the waters" and prevent the Court from drawing the inferences it considered critical to the case, namely, that voter confusion arose from similar party names.

The Court considered the submissions of both parties regarding the disputed paragraphs. The plaintiff argued that the Commonwealth had not provided a credible explanation for its resistance to including facts relating to ballot paper position, especially when similar methodologies were used for other facts. The Commonwealth, through the Solicitor-General, expressed concern that the inclusion of these additional variables would lead to a factual dispute about the correct inference to be drawn from the data, potentially requiring a trial or remittal to resolve, which would be contrary to the purpose of a special case. The Court noted the urgency of the matter and the potential for appeals if inferences were drawn without a clear factual basis agreed upon by the parties.

The Court ultimately indicated a direction towards resolving the factual disputes to allow the matter to proceed. The plaintiff proposed that if paragraphs 58 and 59 were included, they would agree to the omission of paragraph 73. The Commonwealth maintained its position that the proposed additional facts would create a rival inference, making it difficult for the Court to determine the true cause of any observed voter confusion. The Court was grappling with whether the dispute over inferences constituted a factual dispute requiring a trial or could be resolved through submissions to the Full Court.
