Bronson and Child Support Registrar (Child support)

The Administrative Appeals Tribunal (AAT) considered the dispute between Bronson and the Child Support Registrar concerning the percentage of care arrangements for a child. The Registrar had made new percentage of care determinations, revoking existing ones, which Bronson sought to have reviewed.

The primary legal issue before the Tribunal was whether there had been a change to the likely pattern of care of the child that would justify the revocation of existing percentage of care determinations and the making of new ones. The Tribunal was required to assess the evidence presented to determine if the factual circumstances supported a change in the established care arrangements.

The Tribunal's reasoning focused on the evidence presented regarding the actual and anticipated care arrangements for the child. It applied the principles of the *Child Support (Registration and Collection) Act 1988* (Cth) concerning the determination of care percentages, which requires consideration of the likely pattern of care. After reviewing the evidence, the Tribunal found that the Registrar's decision to revoke the existing determinations and make new ones was not supported by the evidence of a significant change in the likely pattern of care.

Consequently, the Tribunal set aside the decision under review and substituted it with its own decision, finding that the existing percentage of care determinations should be maintained.
