913. (1) The Supervisory Authority may—

(a) if it considers it necessary to do so, undertake an interim review of a work programme, and

(b) may submit to the Minister, within the period covered by the work programme, an amended or supplementary work programme, including an amended or supplementary annual programme of expenditure.

(2) An amended or supplementary annual programme of expenditure shall not be included in an amended or supplementary work programme unless it has first been approved in accordance with subsection (3) of section 911 and subsection (2) of that section applies to such an approval as it applies to the approval of an original annual programme of expenditure.

(3) If the Minister so approves with amendments the Supervisory Authority’s amended or supplementary annual programme of expenditure, the powers under section 911(4) are equally available to the Supervisory Authority with respect to its amended or supplementary work programme under this section as they are available with respect to an original work programme and, accordingly, section 911(4) applies, with any necessary modifications, to that amended or supplementary work programme.
