Roberts v Deputy Commissioner of Taxation

The case of Roberts v Deputy Commissioner of Taxation involves a dispute between the applicant and the Deputy Commissioner of Taxation regarding the validity of certain tax assessments. The applicant sought leave to appeal from an order made by the Federal Court, which had dismissed the applicant’s application for an injunction and a declaration that certain tax assessments were invalid. The Federal Court was required to determine whether the applicant had demonstrated that the tax assessments were invalid due to conscious maladministration by the Commissioner of Taxation.

The primary judge considered the principles established in Futuris and outlined several key principles regarding the validity of tax assessments. These principles included the protection provided by section 175 of the ITAA 1936, which shields assessments from challenge due to procedural errors, unless the error results in the absence of an assessment or involves conscious maladministration. The primary judge also noted that an assessment must be definite and certain, and that conscious maladministration must be proven by clear and convincing evidence. The court further held that allegations of corruption or deliberate disregard for the law must be substantiated with more than mere assertions of recklessness or lack of diligence.

In considering the application for leave to appeal, the court assessed whether the applicant had demonstrated a real chance of success on the merits of the appeal, or whether the appeal raised an issue of general importance. The court found that the applicant had not provided sufficient evidence to support the claim that the tax assessments were invalid due to conscious maladministration. The court emphasised that each case must be evaluated on its own facts and that the applicant’s allegations of lack of good faith did not meet the threshold of conscious maladministration as defined by the established legal principles.

Accordingly, the court refused the application for leave to appeal and ordered that the applicant pay the respondent's costs of the application. The decision underscores the high threshold required to challenge tax assessments on the grounds of conscious maladministration and reinforces the protection afforded by section 175 of the ITAA 1936 against procedural errors.
