Blakley and Mossey (Child support)

The applicants, Blakley and Mossey, sought review of a decision made by the Child Support Registrar concerning the percentage of care for their child. The dispute centred on whether there had been a change to the likely pattern of care for the child, which would justify a revocation of existing percentage of care determinations and the making of new ones. The matter came before the court for review of the Registrar's decision.

The primary legal issue before the court was to determine whether the evidence established a change in the likely pattern of care for the child that warranted a departure from the existing percentage of care determinations. This involved assessing the factual circumstances presented by the parties and applying the relevant provisions of the *Child Support (Registration and Collection) Act 1988* (Cth) concerning changes to care arrangements.

The court considered the evidence regarding the actual care arrangements for the child and the likely future care arrangements. It applied the principles established in child support legislation and case law regarding what constitutes a "change in the likely pattern of care." The court found that the evidence did demonstrate a significant and likely ongoing change in the pattern of care. Consequently, the court set aside the decision under review and substituted its own determination regarding the percentage of care.
