(3) In proceedings for an offence against
this section, it is necessary to prove that a move on direction was given
within 6 hours before the person was found to be intoxicated and disorderly in
a public place, but it is not necessary to prove that the person contravened
the move on direction by being so intoxicated and disorderly in the
public place at the time concerned.

sufficient defence to a prosecution for an offence under this section if the
defendant satisfies the court that the defendant had a reasonable excuse for
conducting himself or herself in the manner alleged in the information for the
offence.
(6) For the purposes of this section, a person is
"intoxicated" if--
(a) the person's speech, balance, co-ordination or

(b) it is reasonable in the
circumstances to believe that the affected speech, balance, co-ordination or
behaviour is the result of the consumption of alcohol or any drug.
