drug occurs after operation of vessel
(1) This section
applies to proceedings for an offence against section 70(1) or (3) in
which the results of an oral fluid analysis or a blood test under section 72

(2) If in proceedings
to which this section applies the defendant satisfies the court—
(a) that
the defendant consumed the prescribed drug during the relevant period; and
(b) that
the prescribed drug was not consumed after an authorised person first
exercised powers under section 71 preliminary to the performance of the
alcotest or breath analysis referred to in section 72,
the court may, despite the other provisions of this Act, find the defendant
not guilty of the offence charged.
(3) In
subsection (2)—
"relevant period" means the period between—
(a) the
conduct of the defendant giving rise to the making of the requirement that the
defendant submit to the alcotest or breath analysis referred to in
