65 In my opinion, the submissions of Mr Somerville ought not be accepted. Significantly, it should be noted that in drafting ss 190(1)(b), 190(2), and again in s 190(4) of the NPWA, the deliberate use of the indefinite article "the" when referring to "the offence" and not "an" is a strong textual indicator that a nexus or connection between the acts or omissions and the offence as charged is required. In other words, acts or omission of any offence charged under the NPWA will not suffice for the purpose of s190(1)(b).
66 While this begs the question as to the strength of the necessary connection between the act or omission relied upon as evidence of the offence and the offence as charged, at a minimum the acts or omission must be acts or omissions referrable to the elements of the offence the subject of the summons. Section 190(4) makes it plain that the "evidence of an offence means" (and not "includes") evidence by way of an act or omission of "the" possession offences and "the" harm offences, and not mere potential offending in general under the NPWA.
67 The use of the qualifier "any act or omission" is similarly a deliberate choice by Parliament. As Mr Somerville correctly submitted, it expands the range of acts or omissions evidence of which will enliven the time within which proceedings must be commenced under s 190(1)(b). But the word "any" must be read in the context of s 190(4) as a whole, which includes the words "constituting the offence". It is not at large; it is tethered to the offence as charged.
68 It is unlikely that to be "evidence" for the purpose of s 190(4) of the NPWA, the acts or omissions must mirror exactly the particulars contained in the summons of, for example, the specific threatened species or protected fauna harmed or possessed. Nevertheless, the acts or omissions must form a part of the possession and harm offences under ss 101, 118B, and 118A of the NPWA. They must constitute, at least in part, an element of those offences. Visiting, foraging, and leaving markings in conservation areas is not an element of any of the offences charged.
69 In this regard, evidence of Mr Wade's subjective belief or suspicion that any one of the numerous offences under the NPWA that he identified in the application for a search warrant had been committed by Mr Somerville is not determinative. This amounted to no more than evidence of potential offending in general under that Act and not evidence of "the offence" as charged in the summonses.
70 Furthermore, there is, as OEH correctly submitted, "a great distance between evidence that the accused might be committing and offence and evidence of an act constituting [a particular] offence". The circumstantial evidence that first came to Mr Wade's attention prior to 6 November 2016 rose no higher than evidence that Mr Somerville might be committing, or preparing to commit, an offence. There was nothing unlawful of itself about Mr Somerville being present in the Beni or Goonoo SCAs; being seen on public or private lands; looking into bushes or shrubs or climbing trees; or even being in a caravan on a hot day. Until the search warrant was executed there was nothing linking the coloured tape to Mr Somerville. And Mr Somerville was not observed using the tomahawk or ladder, nor was he seen removing, disturbing, collecting, possessing, or harming any animal, protected fauna, or part thereof. In my view, none of these acts were sufficient to be "any act or omission constituting" the offences contained in ss 101(1), 118A(1), or 118B(1) of the NPWA. At best, these acts amounted to evidence that Mr Somerville was looking or foraging for eggs to collect at some point in the future. But these acts did not constitute an offence under the NPWA, let alone the offences with which he was charged. Accordingly, as at 6 November 2016, there was no evidence of "any acts constituting the" possession and harm offences that had first come to the attention of an authorised officer.
