(1) This section allows the Registrar to amend an assessment of child support payable by a parent for all the children in a child support case for some days in a child support period if:
(a) those days occur in the application period for an income election that the parent has made; and
(b) the application period has ended; and
(c) the annual rate of child support payable by the parent for all the children in the child support case for those days was the minimum annual rate for the period or lower.
(2) The Registrar may amend the assessment to affect the annual rate of child support payable by the parent for those days.
(3) This section does not prevent the Registrar from making a new assessment for part of the child support period.
Note: This section does not limit the power under section 75 to amend assessments (see subsection 75(5)).
