Viavattene, In the matter of an application for leave to issue a proceeding

The applicant, Viavattene, sought leave to issue a proceeding against the respondent, the Commissioner of Taxation. The dispute concerned the Commissioner's assessment of the applicant's tax liability, specifically relating to the deductibility of certain expenses. The application for leave was heard by Gageler J of the High Court of Australia.

The central legal issue before the Court was whether the applicant had established a *prima facie* case that the Commissioner's assessment was incorrect. This required the Court to consider the evidence presented by the applicant and determine if it raised a sufficient doubt about the validity of the Commissioner's assessment to warrant further proceedings.

Gageler J applied the principles governing applications for leave to issue proceedings, which require the applicant to demonstrate a real prospect of success. His Honour considered the nature of the alleged errors in the Commissioner's assessment and the evidence adduced by the applicant in support of those claims. Ultimately, Gageler J found that the applicant had not presented sufficient evidence to establish a *prima facie* case that the Commissioner's assessment was incorrect, and therefore, leave to issue the proceeding was refused.
