Rigby and Batson (Child support)

This matter concerned an appeal by Rigby against an administrative assessment of child support made by the Registrar of the Child Support Agency. The dispute centred on the Registrar's decision to accept an estimate of Rigby's income for the purposes of calculating child support liability. Rigby contended that this estimate should have been refused. The decision was made by S Trotter SM in the [Court Name].

The primary legal issue before the Court was whether the Registrar had erred in accepting the estimate of Rigby's income. This required the Court to consider the relevant provisions of the *Child Support (Registration and Collection) Act 1988* (Cth) and the *Child Support (Assessment) Act 1989* (Cth) concerning the estimation of a liable parent's income when actual income information is unavailable or unreliable. The Court had to determine if the estimate was reasonable and properly made in accordance with the legislative framework.

The Court affirmed the Registrar's decision, finding that the estimate of Rigby's income was properly made and accepted. The reasoning applied was that the Registrar had followed the correct procedures and had sufficient grounds to form the estimate in the absence of satisfactory income particulars from Rigby. The Court applied the principles that the Registrar has a broad discretion to estimate income where necessary to ensure the proper assessment of child support, and that such estimates should not be overturned unless demonstrably unreasonable or contrary to the legislative intent. The appeal was therefore dismissed.
