Tompson and Tompson (Child support)

The Administrative Appeals Tribunal considered the dispute between the parties, identified as Tompson and Tompson, concerning particulars of a child support administrative assessment. The core of the disagreement related to whether the adjusted taxable incomes for past periods for the liable parent should be changed.

The Tribunal was required to determine two key issues. Firstly, whether a decision not to amend the adjusted taxable incomes for past periods for the liable parent should be affirmed. Secondly, whether a decision under review to set aside and substitute the adjusted taxable incomes for past periods for the liable parent should be set aside and substituted.

In relation to the first issue, the Tribunal affirmed the decision not to amend the adjusted taxable incomes for past periods, finding no error in that determination. However, concerning the second issue, the Tribunal set aside the decision under review and substituted its own decision, indicating that the original decision to alter the adjusted taxable incomes was not sound. The Tribunal's reasoning focused on the specific evidence and legislative provisions governing child support assessments and adjustments to income particulars for past periods.
