ACN 154 520 199 Pty Ltd and Commissioner of Taxation (Taxation)

ACN 154 520 199 Pty Ltd (ACN), the applicant, sought to issue summonses for the production of documents from the Commissioner of Taxation and a third party, Gold Corporation. The dispute arose in the context of the Tribunal's review of the Commissioner's objection decisions concerning ACN's claims for input tax credits. While a compromise was reached with the Commissioner, the summons directed at Gold Corporation, which sought documents to challenge the creditworthiness of expert witnesses engaged by the Commissioner, was contested.

The primary legal issues before the Tribunal were whether the summons issued to Gold Corporation was for a legitimate forensic purpose, whether its scope was too broad or oppressive, and the extent to which the Tribunal's coercive summons power could be exercised against a non-party. ACN contended that its commercial rivalry with Gold Corporation meant that the evidence of Gold Corporation's employees, engaged as expert witnesses by the Commissioner, might be biased, and that it was entitled to investigate these credit issues.

The Tribunal acknowledged that while a summons power exists to compel production from non-parties, it must be exercised with consideration for the imposition on that stranger to the litigation. The test for relevance remains the same, requiring a balancing exercise between the potential importance of the documents to the case and the third party's interest in avoiding undue cost and inconvenience. The Tribunal found that a request for correspondence between experts and other Gold Corporation employees relating to giving evidence was appropriate, particularly given ACN's undertaking to pay reasonable costs. However, a request for Gold Corporation's board papers and minutes was deemed too broad and potentially oppressive, as its relevance was unclear and it could encompass highly sensitive documents.

Consequently, the Tribunal ordered that the applicant provide a revised summons to Gold Corporation, giving effect to the Tribunal's reasons for decision, which would refine the scope of the documents sought.
