Spence and Burbidge (Child support)

This matter concerned an appeal by the liable parent, Mr. Spence, against a decision of the Child Support Registrar regarding the adjusted taxable income used for the child support assessment. Mr. Burbidge was the other party to the proceedings. The dispute centred on whether the adjusted taxable income declared by Mr. Spence should be applied to his child support assessment, and if so, whether it should be applied retrospectively.

The primary legal issue before the court was whether the Child Support Registrar had erred in refusing to apply Mr. Spence's declared adjusted taxable income to his child support assessment, and specifically, whether any such application should have retrospective effect. The court was required to consider the relevant provisions of the *Child Support (Registration and Collection) Act 1988* (Cth) and the *Child Support Assessment Act 1989* (Cth) concerning the determination and adjustment of child support assessments based on a liable parent's income.

The court affirmed the decision under review, finding no grounds to apply the adjusted taxable income retrospectively. The reasoning focused on the statutory framework governing child support assessments, which generally requires assessments to be made based on the information available at the time of the assessment or in accordance with specific provisions for retrospective adjustments. In this instance, the court determined that the circumstances did not meet the criteria for a retrospective adjustment of the child support assessment. The appeal was therefore dismissed.
