Ritson and Kinchen (Child support)

This matter concerned an appeal by the father, Mr Ritson, against a decision of the Child Support Registrar, which had been affirmed by a Senior Member of the Administrative Appeals Tribunal (AAT). The dispute centred on the father's child support liability, specifically concerning the assessment of his income and the application of the child support formula. The father sought to have his child support assessment reduced, arguing that the Registrar and the AAT had erred in their calculations and considerations.

The primary legal issues before the court were whether the Senior Member of the AAT had erred in law by: (a) failing to properly consider the father's argument that his income should be assessed at a lower figure than that determined by the Registrar, and (b) failing to properly consider the father's argument that the child support formula should be applied in a manner that resulted in a lower assessment, particularly in light of his financial circumstances and the needs of the children.

The court found that the Senior Member had failed to adequately address the father's submissions regarding his income and the application of the formula. While the Senior Member had acknowledged the father's arguments, the judgment did not demonstrate a proper engagement with the specific evidence and legal principles raised by the father. The court reiterated that in child support matters, the AAT must provide reasons that clearly articulate how it has considered and applied the relevant legislative provisions and the evidence presented by the parties. The failure to do so constituted an error of law.

The court therefore upheld the appeal, setting aside the decision of the Senior Member and remitting the matter back to the AAT for redetermination according to law.
