Regulation 46 Special case — departure direction having effect from date earlier than effective date of current assessmentI1

liability to pay child support maintenance commenced earlier than the effective date of the maintenance assessment in force (“the current assessment”);

an application is made or treated as made in relation to the current assessment which results in a departure direction being given in respect of that assessment;

the applicant was unable to make an application on a date falling within a period in respect of which an earlier assessment had effect because he had not been notified of that earlier assessment during that period; and

if the applicant had been able to make such an application and had done so, the Department is satisfied that a departure direction would have been given in response to that application.
