"convicted" has, in addition to its ordinary meaning, the meaning given by subclauses (2), (3) and (4).
(2) For the purposes of these Regulations, a person is taken to have been convicted of an alleged offence if:
(a) the person has not been found guilty of the offence but asks for the offence to be taken into account when being sentenced for another offence; or
(b) the person has been found guilty of the offence but discharged without conviction.
(3) In addition, a person is taken to have been convicted of a psychoactive substance offence if:
(a) a law provides for the issue, in relation to the offence, of an expiation notice; and
(b) such a notice was issued to the person in relation to the offence; and
(c) the person paid the penalty required by the notice.
(4) However, a conviction that is spent (within the meaning of
Part VIIC of the Crimes Act 1914 ), or has been quashed, is not taken
to be a conviction for the purposes of these Regulations.
