Dietrich and Dietrich (Child support)

The Administrative Appeals Tribunal considered the dispute between the parties, identified as Dietrich and Dietrich, concerning an administrative assessment of child support. The core of the disagreement related to the Registrar's refusal to accept an estimated income figure provided by one of the parties.

The Tribunal was required to determine whether the Registrar had erred in refusing to accept the estimated income provided by the applicant. Specifically, the Tribunal had to assess whether the estimated income was less than the amount likely to be the actual income of the applicant, and if so, whether this refusal was justified under the relevant provisions of the *Child Support (Registration and Collection) Act 1988*.

The Tribunal affirmed the Registrar's decision, finding that the applicant had not provided sufficient evidence or justification to support the estimated income figure. The legal principle applied was that an estimated income figure must be demonstrably likely to reflect the actual income to be accepted by the Registrar. In this instance, the applicant failed to meet this threshold, leading to the affirmation of the original assessment.
