If an authorised
person does something (whether in this jurisdiction or elsewhere) that, apart
from this section, would be an offence, the person is not criminally
responsible for the offence if —
(a) the
thing is done in the course of acquiring or using an assumed identity in
accordance with an authority; and
(b) the
thing is done —
(i)
in the case of an authorised officer, in the course of
his or her duty; or
(ii)
in the case of an authorised civilian, in accordance with
any direction by his or her supervisor under the authority;
and
(c)
doing the thing would not be an offence if the assumed identity were the
person’s real identity.
