(1) A person stops being a registrable offender if—
(a) the person is a registrable offender because of only a single finding of guilt for a registrable offence and either—
(i) the finding of guilt is quashed or set aside by a court; or
(ii) the person's sentence for the offence is reduced or otherwise amended on appeal so that the person would have been a person mentioned in section 9 (1) (b) or (c) had the amended sentence been the original sentence; or
(b) the person is a registrable offender only because the person is subject to a child sex offender registration order and the order is quashed or set aside on appeal.
(2) However, the person does not stop
being a registrable offender under subsection (1) (a) (i) if
the court orders that the person be retried for the registrable offence.
