(3) The defences in s 118D(2) are not consistent with an offence which is constituted by a single act or a single omission.
53 Both parties referred in some detail to other provisions of the Act and analysed in some detail the statutory provisions referred to in s 118D(2). Although this was done at the request of the Court in the hope that it may throw light upon the meaning of s 118D, no significant assistance was gained from these exercises.
54 I do not accept the Service's submission that the defences in s 118D(2) are not consistent with an offence which is constituted by a single act or a single omission. I see no good reason why a single act or a single omission, if it fell within any of the paragraphs of s 118D(2), could not provide a defence assuming the damage was caused by the single act or omission relied upon.
55 Environmental offences are notoriously difficult of proof. While the damage caused to a particular area is often all too evident, the prosecuting authority by its officers, is not present when the actual damage is caused and does not know the precise mechanism by which the damage was caused. The prosecuting authority may be able to ascertain the machinery which the landholder has or used. The landholder may do the work himself or have staff do it or engage contractors. From inspections of the property after the damage has been caused it may be evident that the damage has been caused by an act or acts in that the result produced could not have happened without an act (or, in some circumstances, an omission). However, it may not be possible to identify the particular act or acts causing the damage. Not infrequently the damage will have been committed by a series of acts, for example, driving a mower or a dozer or grader over an area for an hour or so, or even over some days or weeks. It may be some weeks later before an inspection takes place as a result of intelligence received or gathered by the Service.
56 I would adhere to the statements of principle that for continuing offences and facts so related that they amount to one activity and that where an offence is defined in the terms of a course of conduct or state of affairs, the prosecution can rely on a series of closely related acts (or omissions) and is not confined to relying on one act. Nor would I question that the acts or omissions relied upon by the prosecution may take place continuously or intermittently over a period of time. These principles are of appreciable importance in relation to environmental offences. Damage of consequence may be caused by several acts in combination, whereas damage caused by one act may be inconsequential. I regard the present case as a borderline one.
57 Part of the problem arises from the terms in which s 118D(1) is expressed and part from the terms of the proposed amendment.
58 In the present case the Service has by using the words "slashing, clearing, and/or crushing vegetation and/or constructing access tracks" in the proposed amendment relied on a series of acts on a 44 hectare property, each of which would constitute an offence. The methods and acts used to cause the alleged damage to the habitat are peculiarly within the knowledge of the defendants. Apparently, and not unexpectedly, the Service is not able to relate any particular act to any particular damage. The amendment proposed requires the defendants to meet a series of acts unrelated to any particular damage and over a wide area.
59 The essence of the offence is doing anything that causes damage to any habitat (other than a critical habitat) of a threatened species. The "doing anything" must be by an act or omission and that is an element of the offence and would have to be included in the charge. However, it does not follow that the "act" would have to be specified in the way in which this has been proposed in the amendments. In the factual particulars delivered with the statement of the charge in the summons the nature of the damage could be described in some detail followed by the statements that, by necessary inference, such damage must have been caused by an act, specifying any further facts and circumstances relied upon. It should then be stated that these are the best particulars that the prosecutor can supply, and, if it be the fact, that the prosecutor is not able to give further particulars of the act causing the damage. The draftsman of the charge and particulars may well be able to improve substantially on the outline I have suggested.
60 There are other problems which will need to be addressed. The damage may vary significantly over the 44 hectare property. This may necessitate different charges as the nature of the act required to inflict different types of damage may also differ significantly. It will be a question of degree. The Service proposed to amend the summons by deleting the word "and" and substituting the words "and/or" where reference is made to the two Lots on which the damage is said to occur. This requires some explanation or justification.
61 The amendments permitted are, at the very least, embarrassing and should not have been allowed.. As framed they require the applicants to meet a number of different cases any one of which, if proved, would constitute the offence charged. This is not to say that amendments differently framed would not have been permissible.
62 The question remains what should be done when the amendments permitted should not be allowed to stand. I would favour remitting the matter to the judge with the Service, if so advised, being at liberty to make an amendment application to elucidate the charge and reformulate its particulars. The argument before the judge concentrated on a matter of substance, namely, what was the essence of the offence with insufficient attention being paid by the Service to matters of form.
63 Having regard to the way in which s 118D is framed and the difficulties it poses, both as to matters of form and substance, there are considerable practical obstacles in the Service being able to make effective use of that section in its efforts to protect the environment by preventing damage to the habitats of threatened species, endangered populations or endangered ecological communities. As mentioned, the facts as to how damage was caused will be peculiarly within the knowledge of the potential defendants, for example, the landholder, his staff, his sharefarmer or his contractors. Amendment of the section should be considered.
64 As the amendments proposed by the Service were faulty as to form it must bear the costs of the application to amend before the judge and of the proceedings before this Court.
65 I propose the following orders:
1. Leave to appeal granted.
2. Appeal against the order of Cowdroy J of 9 July 2004 permitting the amendment allowed; Order set aside.
3. Remit the question of amendment of the charges specified in the summonses to the Land and Environment Court to consider such further application for amendment by the informant on behalf of the Service as it may wish to make and for directions for the further hearing of the summonses.
4. Order that the informant pay the costs of Hugh Charles Gordon and BGP Properties Pty Limited of the application to amend the charges in the summonses before the Land and Environment Court and the proceedings in this Court.
