Castle and Jonas (Child support)

The case of *Castle and Jonas* concerned a dispute over the percentage of care for a child. The applicant, Castle, sought to have existing percentage of care determinations revoked and new determinations made, alleging a change in the likely pattern of care. The respondent, Jonas, contested these claims. The matter came before the court for review of a decision made by the Child Support Registrar.

The primary legal issues before the court were whether there had been a change to the likely pattern of care for the child, and consequently, whether the existing percentage of care determinations should be revoked and new ones made. The court also had to consider the application of interim periods following the revocation of determinations, particularly in light of the maximum interim period prescribed by the relevant legislation.

The court affirmed the decision under review, finding that the Registrar had correctly applied the relevant provisions of the *Child Support (Registration and Collection) Act 1988*. The reasoning focused on the evidence presented regarding the actual and likely future care arrangements for the child. The court determined that the circumstances did not warrant a departure from the existing determinations, and that the Registrar had acted within their powers in making the original decisions. The court also considered the effect of non-compliance with court orders in relation to the care arrangements.
