South Australian Consolidated Acts9—Defences to charge of an offence
It is a defence to a charge of an offence under section 6 or 7 if the
defendant proves that—
(a) the
dumping the subject of the charge was necessary to secure the safety of human
life, or of a vessel, aircraft or platform, at sea in a case of force majeure
caused by stress of weather; or
(b) the
dumping the subject of the charge was the only reasonable way of averting a
threat to human life, or to the safety of a vessel, aircraft or platform, at
sea and there was every probability that the damage caused by such dumping
would be less than would otherwise occur,
and, in either case, that—
(c) the
dumping was so conducted as to minimise the likelihood of damage to human or
marine life; and
(d) a
report of the dumping, setting out the prescribed information, was furnished
to the Minister as soon as practicable after the occurrence of the dumping.
