Oliver v Oliver

This case involved an appeal by Mr Oliver (the Applicant) against a decision of the Administrative Appeals Tribunal (AAT) concerning child support assessments for his two children. Ms Oliver was the First Respondent and the Child Support Registrar was the Second Respondent. The dispute centred on the AAT's decision to vary child support assessments to account for the costs of the children attending a private grammar school.

The court was required to determine whether the AAT erred in finding that a ground for departure from the standard child support assessment existed under section 117(2)(b)(ii) of the *Child Support (Assessment) Act 1989* (Cth). Specifically, the Applicant argued that the AAT failed to consider whether the agreement for the children to attend the school was conditional on the First Respondent paying the associated fees, and therefore the costs of maintaining the children were not significantly affected. The Applicant also contended that the AAT denied him natural justice by failing to consider other potential grounds for departure.

McNab J dismissed the Applicant's grounds of appeal. The court found that the AAT correctly applied section 117(2)(b)(ii) by determining that there were special circumstances, the children were being educated in a manner expected by the parents, and the costs of maintaining the children were significantly affected. The AAT's finding that the Applicant acceded to the children attending the school and did not want to "stand in the way" was sufficient, and it was not necessary for the Applicant to have committed to paying the fees for the ground of departure to be established. Furthermore, the court held that as the AAT had established a valid ground for departure under section 117(2)(b)(ii), it was not required to consider other potential grounds for departure, thus negating the natural justice argument.

The originating application was dismissed, and the Applicant was ordered to pay the Second Respondent's costs fixed at $8,700.
