Isaacson and Child Support Registrar (Child support)

The Administrative Appeals Tribunal (AAT) considered the matter of *Isaacson and Child Support Registrar*. The dispute concerned the Registrar's refusal to grant an extension of time for the applicant, Isaacson, to lodge an objection against a child support assessment.

The primary legal issue before the AAT was whether the Registrar had erred in refusing to grant the extension of time. This required the Tribunal to assess whether Isaacson had provided a reasonable explanation for the delay in lodging the objection and whether there were arguable merits to the proposed objection, balanced against any prejudice to the other parent.

The Tribunal found that Isaacson had provided a reasonable explanation for the delay and that the proposed objection had arguable merit. Crucially, the Tribunal determined that granting the extension of time would not cause prejudice to the other parent. Applying these considerations, the AAT concluded that the Registrar's decision to refuse the extension of time was not justified. The Tribunal set aside the decision under review and substituted it with a decision to grant the extension of time.
