The scientific expert, Mr Roach, reported, on affidavit, his interpretation of the test results. In essence, his evidence is of no actual environmental harm, but a potential for harm. He says (in par12):
"Given this information and the possibility that the discharge only occurred for 2 hours, though it is possible it may have been longer, then it is difficult to be emphatic about the likelihood that some impact occurred. As discussed above the pH of the water was at a level where there was a potential for environmental effects if it had discharged into a relatively undisturbed environment. Secondly it adds, albeit to a small degree, to cumulative environmental impacts from acid water discharges in the Tweed River generally which is widely considered to be a significant environmental problem in the catchment."
49 The information to which Mr Roach had been referring related, inter alia, to the water flow and pH of watercourses connected with the creek into which the discharge had occurred. He had also observed that he would have expected small fish to have been present but no dead organisms were in fact noted.
50 It was submitted on behalf of the Applicant that "the offence did cause actual environmental harm to the extent that it added to the cumulative environmental impacts from water discharge in the Tweed River generally. Reliance was placed on the statement "A Defendant discharging acidic waters into waters already so degraded should not be given any advantage by way of mitigation simply because the receiving waters are in a degraded state. In such circumstances, the enforcement of the State's anti-pollution laws ought to be attended with greater rigour and enthusiasm to bring about an improved state of affairs in an already degraded water environment" - State Pollution Control Commission v White Wings Limited (unreported, Bignold J, 1 November 1991).
51 Despite these remarks, s241 obliged his Honour to take into account - it being clearly relevant - the extent of the harm actually caused. When regard is had to his Honour's use of the expression "In essence" and his quotation from the report of Mr Roach, it is impossible to conclude that his Honour misapprehended the impact of the Respondent's offence on the environment.
Ground 3(vi)
His Honour erred … in the weight given to the potential for environmental harm rather than to the circumstances leading to the offence.
52 His Honour properly dealt with both of these topics in his remarks and there is nothing but the size of the fine imposed to support this ground. It does not.
Ground 3 (vii)
His Honour erred … in taking into account an agreement by the Respondent to pay the prosecutor's costs.
53 What his Honour said was that "I also taken into account (the Respondent's preparedness to pay the Prosecutor's costs, and the unlikelihood of further offences of this type in all the circumstances."
54 Liabilities such as costs or the cost of rectification consequent on an offence are relevant in any consideration of the size of any fine to be imposed. However, it is difficult to see how in accordance with normal principles an order for the payment of costs would not have been made in any event and thus I doubt whether the Respondent's simple "preparedness" was of significance. However, his Honour's reference in the same sentence to the possibility of further offences does raise the question whether the reference the subject of this ground was directed to the topic of contrition or further offending rather than to the size of the fine directly. However I am prepared to assume the ground is made out.
Ground 3 (viii)
His Honour erred … in taking into account a finding that there was an unlikelihood of further offences of these types.
55 An assessment of the likelihood of further offending is relevant to considerations of personal deterrence, and protection of the community, 2 of the 5 purposes to which criminal punishment is directed - Veen v R (1987-1988) 164 CLR 465 at 476. It may be, as the Applicant submitted that the finding may have been based on evidence from Mr Burridge that the sand mine had been sold but that does not make the matter one to which no, or lesser, weight should be given. A person who has offended against the drink driving legislation is entitled to have taken into account in mitigation a sale of his motor vehicle effected in order to reduce the likelihood of repetition of offending.
56 This ground fails.
Ground 1
57 This submission takes too simplistic a view of the significance of the maximum penalty provided. Environmental offences are liable to be committed by a wide variety of persons - from lowly paid employees to the largest corporations in the State. They are liable to be committed in a wide variety of circumstances including by accident and even despite a great deal of care: They may be committed deliberately after a cost/benefit analysis by the perpetrator. They may result in no, or alternatively a great deal of, environmental damage. To ensure all such persons and situations are covered, to ensure that penalties are sufficient to hurt even very large corporations and to induce the taking of precautions, even costly precautions, the maximum must be high.
58 Recognition must be given to the situation of an offender. A fine which would operate as no significant imposition on a large corporation might well ruin a smaller one. $10,000 is no insubstantial sum and the fact that it was imposed on a corporation and is but 4% of the maximum does not of itself demonstrate that it was inadequate, particularly appellably inadequate. Nor does it show that his Honour did not pay regard to the increase in the maximum penalty in 1997.
59 In that connection, it must not be forgotten that there were a number of matters on which the Respondent could rely in mitigation. Some are referred to above. Another which merits specific mention is the Respondent's plea, albeit it must be acknowledged that the Respondent was caught red-handed and the Crown case very strong.
Other Matters
60 The Notice of Appeal which was filed stated as the sole ground of appeal that the sentence was inadequate. The Crown has established some of its more particular complaints and thus the discretion of this Court to interfere is enlivened. However it is common ground that the usual principles of double jeopardy apply. The errors which did occur were, in the context of the whole of his Honour's judgment, of relatively little significance. I am not persuaded that the sentence was one which was outside the legitimate exercise of his Honour's sentencing discretion. In these circumstances, I am not persuaded that the Court should interfere.
61 I would dismiss the appeal.
62 BARR J: I agree with Hulme J.
