The provisions of Part III of these Regulations shall not apply to a case in which there is a maintenance assessment in force on the date they come into force unless the absent parent in relation to whom that assessment was made makes an application for a review of that assessment under section 17 of the Act F1before 1st June 1999 or an application on or after that date for a decision under section 17 of the Act superseding an earlier decision.

Such an application must be made not later than 3 months after the date when these Regulations come into force, but if an application is made after that period it may be accepted if the Secretary of State is satisfied that there is good reason for its being made late.

Regulation 10(2) of the Procedure Regulations shall not apply in respect of a decision made solely for the purpose of applying Part III of these Regulations but instead the Secretary of State shall notify the relevant persons (as defined in regulation 1(2) of the Procedure Regulations) of the detail of how the provisions of Part III of these Regulations have been applied in that case.
