Section 603 provides that any agency action taken pursuant to section 602 shall be subject to such judicial review as would be available for similar actions by that agency on other grounds. Where the agency action consists of terminating or refusing to grant or to continue financial assistance because of a finding of a failure of the recipient to comply with the agency's requirements imposed under section 602, and the agency action would not otherwise be subject to judicial review under existing law, judicial review shall nevertheless be available to any person aggrieved as provided in section 10 of the Administrative Procedure Act (). The section also states explicitly that in the latter situation such agency action shall not be deemed committed to unreviewable agency discretion within the meaning of section 10. The purpose of this provision is to obviate the possible argument that although section 603 provides for review in accordance with section 10, section 10 itself has an exception for action "committed to agency discretion," which might otherwise be carried over into section 603. It is not the purpose of this provision of section 603, however, otherwise to alter the scope of judicial review as presently provided in section 10(e) of the Administrative Procedure Act.
