OVERVIEW
4The waste in issue was deposited on two areas of land at 190 Cattai Ridge Road, Maraylya being Lot 1 DP 566767 (the Land). The two areas were described in evidence as "Fill Body 2" with an area of 900 square metres, and "Fill Body 1" with an area of 1,850 square metres. There were 950 cubic metres of fill in Fill Body 2, which weighed an estimated 1,425 tonnes. There were 2,050 cubic metres in Fill Body 1, which weighed an estimated 3,075 tonnes. The totals were therefore 3,000 cubic metres weighing an estimated 4,500 tonnes. Fill Body 2 included brick, piping, hessian and fragments of asbestos-containing fire cement sheeting. Fill Body 1 included brick, metal, concrete, bitumen, artificial grass and fragments of asbestos-containing fibre cement sheeting. The material in the two fill bodies did not comprise excavated natural material and analysis of samples revealed elevated levels of Benzo(a)Pyrene.
5The Land is a large rural lot owned by Ralph and Suzanne Clark. They have lived and conducted businesses from there since the 1980's.
6The defendant Mr Kinnarney resided next door where he conducted a business through the corporate defendant. As its name suggests, the business of the corporate defendant involves earthworks. Mr Kinnarney is the sole director and shareholder of the corporate defendant, and he is its controlling mind and will, and drove its truck during the relevant period .
7Mr Kinnarney did not give evidence.
8It is common ground that:
(a)An oral arrangement was entered into between Mr Clark and Mr Kinnarney for Mr Kinnarney to transport and deposit fill on the Land for which Mr Clark would charge a fee. The object was to contribute to the creation of a firebreak. I find that the arrangement was entered into in late 2009.
(b)Thereafter Mr Kinnarney deposited fill on the Land using the corporate defendant's truck and trailer. I find that he did so between about and including late 2009 and June 2010.
(c)Between January and July 2010 Mr Kinnarney paid for depositing the fill by six cheques he drew on the corporate defendant's bank account against six invoices which he received from Mr Clark's company. Five of the six invoices are in evidence and are dated from January 2010 to July 2010. They were paid on or within days after the dates they bore. The sixth invoice cannot be located but, judging by its payment date of 4 May 2010 and the pattern of payment of the other invoices, it most likely was invoiced on or shortly before 4 May 2010.
9The fill transported by Mr Kinnarney constituted "waste" as defined in the POEO Act even if it was clean. In fact, I find that it contained the various materials referred to above at [4]. He transported it to a place that could not lawfully be used as a "waste facility" as defined in the POEO Act. This is not disputed.
10On the basis of the undisputed matters outlined above, the defendants are guilty of the offences charged subject to consideration of their only defence, identified on the first day of the trial, namely, the common law defence of honest and reasonable mistake of fact.
11The only other issues the defendants identified on the first day of the trial go not to guilt but to the seriousness of the offences, namely, the amount of fill and whether it was clean. However, the latter issue was not pressed in submissions, presumably because of the unchallenged evidence that it included a large amount of demolition material and the like.
12Calculation of the amount of fill turns on the rate paid per load and what constituted a load, neither of which were recorded on the invoices nor elsewhere in writing. I accept Mr Clark's evidence that he and Mr Kinnarney orally agreed that Mr Kinnarney would pay $100 plus GST per load; that periodically Mr Kinnarney informed Mr Clark how many loads he had delivered so they could be invoiced; and that a load was treated as a combined truck and trailer load (each with a capacity of a little over 10 tonnes, total 20 tonnes). The defendants submit that the rate was $200 per load (plus GST), but there is no evidence of that rate.
13On the basis of a rate of $100 per load of about 20 tonnes and the defendants' admitted payments of the invoices in the total amount of $16,550 (excluding GST), I conclude that Mr Kinnarney deposited approximately 3,310 tonnes of waste on Fill Bodies 1 and 2 in the six or seven months before 1 July 2010. Of this amount, I am satisfied that he deposited all the waste of 1,425 tonnes on Fill Body 2, and that the balance of his waste, approximately 1,885 tonnes, was deposited on Fill Body 1.
14A further issue, identified by the defendants in closing submissions, is whether Mr Kinnarney pushed fill over the escarpment on Fill Body 1. Having regard to the totality of the evidence and my assessment of Mr Clark's credit recounted later, I do have a reasonable doubt about whether Mr Kinnarney did so, and therefore I do not find that he did.
15Turning to the common law defence of honest and reasonable mistake of fact, the defendants say that Mr Kinnarney's mistake of fact was that, in reliance on what Mr Clark told him, he believed that Mr Clark had development consent which permitted the deposit of the fill on the Land under the Environmental Planning and Assessment Act 1979 (EPA Act). Although Mr Kinnarney did not give evidence, 15 propositions were put to Mr Clark in cross-examination, which the defendants say encapsulate this defence. Many of them Mr Clark denied or said he did not recall and there is no other evidence of them. Nevertheless, the defendants argue that the 15 propositions should be accepted as establishing the defence or as giving rise to a reasonable doubt as to whether they are guilty.
16The defendants submit, and I accept, that in assessing whether there is reasonable doubt in any respect, there should be taken into account damage to the credit of the main prosecution witness, Mr Clark, because:
(a)he admitted in cross-examination to lying to the Council investigating officers when they interviewed him on 1 July 2010 and to similarly lying in his two affidavits; and
(b)he was granted an indemnity against prosecution by the Council on 21 July 2010, even though he was criminally involved in and profited from the defendants' activities, on the basis of no more than his interview by Council officers and before the Council had conducted any further significant investigation.
17Consequently, I treat Mr Clark's evidence with particular caution. Nevertheless, having assessed his oral evidence, I do accept some but not all aspects of his evidence including evidence favourable to the defendants.
18In my opinion, the defence raised of honest and reasonable mistake of fact fails for at least three reasons. First, the alleged mistake was not one of fact but one of law, or alternatively was one of mixed fact and law, which is to be treated as a mistake of law. Secondly, the alleged belief, if true, would not take the defendants outside the operation of the POEO Act because lawful authority was required not only by development consent under the EPA Act but also by an environment protection licence under the POEO Act Chapter 3. Thirdly, in any event the defendants have not satisfied their evidential burden of proving that Mr Kinnarney was honestly and reasonably mistaken as alleged.
19Consequently, I propose to find the defendants guilty as charged.
20Having stated my conclusions shortly and summarised the main evidence and reasoning, I now proceed to a more detailed analysis.
