(1) Subject to subsection (2) and sections 1206U and 1206V, if:
(a) a person applies in writing to the Secretary for a special employment advance deduction to be decreased, or to be stopped, because of severe financial hardship; and
(b) the Secretary is satisfied that:
(i) the person's circumstances are exceptional and could not reasonably have been foreseen at the time of the person's claim for the special employment advance; and
(ii) the person would suffer severe financial hardship if the special employment advance deduction that would otherwise apply were to continue;
the Secretary may determine in writing that, for the period stated in the determination, the special employment advance deduction is to be a lesser amount (which may be a nil amount) stated in the determination.
(2) At any time while the determination is in force, the Secretary may:
(a) vary the determination so as to require to be deducted from the person's rate a special employment advance deduction larger than the deduction (if any) previously applying under the determination, but smaller than the deduction applying immediately before the determination; or
(b) revoke the determination;
but only if the Secretary is satisfied that the person would not suffer severe financial hardship because of the variation or revocation.
(3) A variation or revocation of a determination must be in writing.
