Holst and Marinos (Child support)

The Administrative Appeals Tribunal considered the dispute between Holst and Marinos concerning a child support administrative assessment. The core of the disagreement involved whether additional income earned by one of the parents after the parties' separation should be excluded from their adjusted taxable income for the purposes of calculating child support.

The Tribunal was required to determine whether the additional income, earned by the father since the separation, constituted "income from other sources" that should be disregarded under the *Child Support (Registration and Collection) Act 1988* (Cth). Specifically, the Tribunal had to assess if this income was of a nature that warranted exclusion from the father's adjusted taxable income when calculating his child support liability.

The Tribunal affirmed the decision under review, finding that the additional income earned by the father was not of a nature that should be excluded from his adjusted taxable income. The Tribunal applied the principles of the *Child Support (Registration and Collection) Act 1988* (Cth) and relevant case law, concluding that the income was assessable for child support purposes. The Tribunal's reasoning focused on the nature of the income and its relationship to the father's earning capacity.
