A. Misconstruction of definition of water pollution (charges 866, 180)
6Water pollution is defined in the PEO Act as:
(a) placing in or on, or otherwise introducing into or onto, waters (whether through an act or omission) any matter, whether solid, liquid or gaseous, so that the physical, chemical or biological condition of the waters is changed, or
(b) placing in or on, or otherwise introducing into or onto, the waters (whether through an act or omission) any refuse, litter, debris or other matter, whether solid or liquid or gaseous, so that the change in the condition of the waters or the refuse, litter, debris or other matter, either alone or together with any other refuse, litter, debris or matter present in the waters makes, or is likely to make, the waters unclean, noxious, poisonous or impure, detrimental to the health, safety, welfare or property of persons, undrinkable for farm animals, poisonous or harmful to aquatic life, animals, birds or fish in or around the waters or unsuitable for use in irrigation, or obstructs or interferes with, or is likely to obstruct or interfere with persons in the exercise or enjoyment of any right in relation to the waters, or
(c) placing in or on, or otherwise introducing into or onto, the waters (whether through an act or omission) any matter, whether solid, liquid or gaseous, that is of a prescribed nature, description or class or that does not comply with any standard prescribed in respect of that matter,
and, without affecting the generality of the foregoing, includes:
(d) placing any matter (whether solid, liquid or gaseous) in a position where:
(i) it falls, descends, is washed, is blown or percolates, or
(ii) it is likely to fall, descend, be washed, be blown or percolate, into any waters, onto the dry bed of any waters, or into any drain, channel or gutter used or designed to receive or pass rainwater, floodwater or any water that is not polluted or, ...
if the matter would, had it been placed in any waters, have polluted or have been likely to pollute those waters.
(emphasis added by the Council)
7The magistrate held there was no evidence of water pollution in relation to both charges. I note the events giving rise to these occurred relatively close together on 1 December 2010 (charge 866) and 10 January 2011 (charge 180). Her reasoning made reference to dictionary definitions of pollution and further included (TS4.23 - 39, 15 June 2012):
This information relates to polluting waters - that is, 180 - as does penalty notice ending in 866. As stated earlier in these remarks, the Court notes the definitions of "pollutant waters" contained in the legislation as well as in the dictionaries referred to clearly it is not sufficient to merely describe what can be observed with the naked eye. ...
There must be evidence of some aspect of the alleged "polluting waters" to show that the physical, chemical and biological characteristics of the water had been altered in such a way or to such an extent that it can affect the health or survival of life forms in an undesirable way. Alternatively, there must be evidence in relation to the water of the introduction of any matter to make the waters unclean, noxious, poisonous, impure or detrimental to the health, safety, welfare or property of persons, or harmful to animals, aquatic life, birds or fish, and I have to say there is no such evidence before the court, and accordingly those informations [sic] are dismissed.
8The Council submitted that the magistrate did not refer to the deeming of pollution in paragraph (d) of the definition. The Council relied in written submissions on this part of the definition at the local court hearing. The magistrate refers to definitions of water pollution in several dictionaries, which the parties did not refer to. In failing to refer to that part of the definition the magistrate misconstrued it. That error vitiated her decision as there was evidence which supported a finding of guilt under paragraph (d) of the definition. Photographic evidence of each offence relied on by the Council showed sediment apparently from the site in such a position (for example, statement of Ms Evelyn Baker dated 10 November 2011 attachment F, statement of Mr Adam Steven (undated) attachment 1). The Respondent's expert Dr Daniel Martens, a civil and environmental engineer, gave evidence (TS29.9 - 17, 23 April 2012) that the road sloped downhill to the gutter on both sides:
Q. On Dumaresq Street adjacent to the site you accept that the centre of the road slopes downhill to the gutter on both sides, don't you?
A. I didn't take any measurements. It appeared to be a crowned road with the fall either side of the crown going towards the gutter.
Q. That being the case dirt which was at the centre of or on the opposite side of the road would be in a position where it might descend or be washed into the gutter at some point.
A. Yes.
9The Respondent submitted that no question of law alone is identified with reasonable precision in relation to the magistrate's reasoning on water pollution, a requirement identified in R v JS [2007] NSWCCA 272; (2007) 175 A Crim R 108 at [75]. It is conceded that there is no express reference to the deeming provision in paragraph (d) of the definition of water pollution. The real criticism of the Council is inadequacy of reasoning. That is not the appeal ground articulated.
10That there is no reference to the deeming part of the definition does not automatically mean that the magistrate misconstrued the definition. Such a conclusion should not be lightly drawn. Further, that the magistrate did not deal with deemed pollution is not a question of law alone but a question of mixed fact and law. The magistrate did make findings of fact and explicitly applied the definition of water pollution to these in arriving at her conclusion. The magistrate's approach did not turn on the deeming provision, rather she found there was an absence of evidence to support the charges, being evidence of the condition of the receiving waters. Further, even if there was a question of law alone able to be raised in this appeal by the magistrate it was not vitiating.
