3. The provision of the particular by the prosecution that: 'The premises are situated at the Barrabup State Forest ... [and] the premises are a work site within the forest' (p 15) was an inadequate particular to provide the Applicant with a proper opportunity to prepare a defence. That is particularly so when it later emerged in evidence that the so-called premises, to which the prosecution was adverting was a work-site compromising a 'coup' (or area of forest), which was defined only by boundaries which were marked on a map which was in the possession of the officers of the Forest Products Commission, 'displayed at the front office of the CALM office' (wherever that may be) and available to the Respondent (pp 17, 19-20, 23, 25, 27, 34, 35-36).
4. In the situation where the prosecution had failed to provide adequate particulars, it was then the duty of the magistrate to order that adequate particulars be given. If an application for particulars is made and refused by the prosecution and the Magistrate, no matter how strong the evidence might have proved, any conviction would be set aside on appeal: Cochran v Price [1943] St R Qd 122, per Webb CJ at 125.
5. Counsel for the Appellant at the commencement of the trial (p 17) sought particulars as to the definition of the premises, which defined them more clearly than they had been defined by the particular given, i.e., 'a work site within the Barrabup State Forest'. The Magistrate ruled that the definition given was a clear definition, and effectively refused the application for particulars.
6. An accused person has a right to apply for particulars, which goes beyond the description of the offence in accordance with the statutory provision upon which it is based. The accused also has a right to have that application considered according to the rules dealing with the exercise of a judicial discretion: Cochran v Price [1943] St R Qd 122, per Philp J at 129. In this case, as in Cochran's case, there was no ground for the refusal of the application for particulars.
7. It cannot be said what would have been the evidence if the defendant had not been deprived of her primary right to particulars, so it cannot be said that no substantial miscarriage of justice occurred. The conviction should be quashed upon the ground that there has been no trial according to the form of law: Cochran v Price [1943] St R Qd 122, per Philp J at 130; see also Lafitte v Samuels (1972) 3 SASR 1 per Bray CJ at 8-9, Mitchell J at 13-14, Zelling J at 16-17 and 20; Romeyko v Samuels [1972] 2 SASR 529; Johnson v Miller [1937] HCA 77; (1937) 59 CLR 467 per Evatt J at 498.
8. In order for an offence to be committed which includes an element of remaining on premises, the premises in question must be clearly defined. Premises can only be such if they are 'specific and tangible', rather than 'notional or metaphorical': see Hasluck J in Molina v Zaknich [2000] WASCA 390; (2000) 117 A Crim R 346 at 355. As a matter of fundamental principle, before criminal responsibility could be attached to the fact of a person remaining in a particular place, it must be objectively possible for that person to be aware of the tangible and specific definition of the dimensions of the premises upon which it is alleged that person is remaining. In Molina v Zaknich Hasluck J said 'it was clear to anyone approaching the BGC site that it was a particular and defined area because there was cyclone fencing all around it' and it was 'clear from the evidence that the only area designated as a site or capable of being regarded as "the" premises was a fenced area occupied by BGC Constructions'. Similarly, in McGinty v Webb, unreported decision Nicholson J, 27 November 1990, SCWA Library No 8606, the Old Swan Brewery site was obviously defined by fencing and the natural features of the Swan River, Mt Eliza and Mounts Bay Road. By contrast, in the present case, the area, which the charge purported to include within the concept of premises, was an area delineated upon a map comprising 1600 hectares (Exhibit A) (pp 19, 27). That is a definition of premises which lacks the element of tangibility which must be present to attract the criminal liability contemplated by the offence created by section 82B of the Police Act.
9. The offence of remaining on premises can only occur following a warning to leave particular defined premises. In order for such warning to be complete it must convey to the offender sufficient information for the offender to know what the premises are which the offender must leave. In order for the Applicant to have had the requisite knowledge, it would have been necessary for her to have inspected the map which defined the area alleged to be the premises.
10. There was insufficient evidence upon which the Magistrate could reasonably conclude that the Applicant inspected the map, or otherwise acquired the requisite knowledge, for there to have been a warning given to her sufficient to satisfy that prerequisite to the commission of the offence. Mr Mammone's evidence (pp 28-29) is insufficient to support a conclusion that the Applicant was aware of the content of the map. The evidence of Constable Kingma (p 34) was that the map was shown to Lauren Caulfield and Simon Pettifry and that 3 or 4 other people, whom he could not identify, were in close proximity who would have been able to see that the map had been pulled out and an area was being pointed to. That evidence was insufficient for the Magistrate to conclude (p 41, para 4) that he was satisfied beyond reasonable doubt that the Applicant was 'within audible range of Constable Kingma at the time ... that he was describing' the area which comprised the premises the subject of the warning. Further, even assuming that the Applicant was within audible range of Constable Kingma, it would have been necessary for a person to not only hear what was being said, but also to inspect the map which was being referred to, in order to acquire the necessary knowledge of the area which Constable Kingma was describing to Lauren Caulfield and Simon Pettifry."
