A charging authority shall notify the Secretary of State in writing of any amount calculated by it under section 95(4) above, whether originally or by way of substitute.

A relevant precepting authority shall notify the Secretary of State in writing of the amount of any precept issued by it under this Act, whether originally or by way of substitute.

A notification under subsection (1) or (2) above must be given before the end of the period of seven days beginning with the day on which the calculation is made or the precept is issued (as the case may be).

The Secretary of State may serve on a charging authority or relevant precepting authority a notice requiring it to supply to him such other information as is specified in the notice and required by him for the purpose of deciding whether to exercise his powers, and how to perform his functions, under this Part.

The authority shall supply the information required if it is in its possession or control, and shall do so in such form and manner, and at such time, as the Secretary of State specifies in the notice.

An authority may be required under subsection (4) above to supply information at the same time as it gives a notification under subsection (1) or (2) above or at some other time.

If an authority fails to comply with subsection (1) or (2) above, or with subsection (5) above, the Secretary of State may decide whether to exercise his powers, and how to perform his functions, under this Part on the basis of such assumptions and estimates as he sees fit.

In deciding whether to exercise his powers, and how to perform his functions, under this Part the Secretary of State may also take into account any other information available to him, whatever its source and whether or not obtained under a provision contained in or made under this or any other Act.
