31Special provisions where directions replace, or extend periods under, previous directions
(1)Where any such direction as is mentioned in section 28(2), (3) or (4)(c) above is given while a person's registration is subject to conditions or suspended by virtue of a direction under this Act, his registration shall continue to be conditional or suspended throughout any period which may intervene between the time when (but for this subsection) his registration would cease to be conditional or suspended, as the case may be, and the time when—
(a)the period for bringing an appeal against the direction under section 29 above expires ; or
(b)if such an appeal is brought, the appeal is determined or withdrawn or is struck out for want of prosecution.
(2)If, however, on the determination of any appeal under section 29 above any such direction as is mentioned in section 28(2), (3) or (4)(c) above takes effect after the time when (but for subsection (1) above) the current period of conditional registration or suspension referred to in the said provision of section 28 would have ended, the period for which that direction is to have effect shall be treated as having started to run at that time.
