Derrick and Derrick (Child support)

The matter of *Derrick and Derrick (Child Support)* concerned an appeal to the Administrative Appeals Tribunal (AAT) regarding a child support assessment. The applicant, Mr Derrick, sought to challenge a decision made by the Registrar of the Child Support Agency concerning the percentage of care for the parties' child. The core of the dispute revolved around whether there had been a significant change in the pattern of care that would warrant a reassessment of child support obligations.

The Tribunal was required to determine two primary legal issues. Firstly, whether the applicant had established that there was a change in the pattern of care for the child that was likely to be significant and continuing. Secondly, the Tribunal had to consider whether to grant leave for a late objection under section 87AA of the *Child Support (Registration and Collection) Act 1988*, given that the objection was lodged outside the prescribed time limits.

In its reasoning, the Tribunal acknowledged the applicant's assertion of a change in care arrangements. However, it found that the evidence presented did not sufficiently demonstrate a change in the pattern of care that was likely to be significant and continuing, as required by the legislation for a reassessment. The Tribunal also considered the application for a late objection, noting the discretion available under section 87AA. Ultimately, the Tribunal concluded that the grounds for granting leave for a late objection were not met, and therefore, the original decision of the Registrar stood.
