Analysis of Grounds 2 and 3
40 The provisions of s.25, which an applicant for a final order authorising the carrying out of a forensic procedure must satisfy, can only be met by information or material being placed before a magistrate that establishes the matters specified in the sub-paragraphs of that section.
41 In the present matter, the first defendant purportedly addressed the factual matters relevant to s.25(f) in paragraph 5 of the affidavit. That paragraph, as earlier noted, simply states, "see paragraph 2". One accordingly turns to that paragraph in order to determine whether the evidence contained in it is sufficient to satisfy the preconditions or requirements specified in s.25(f).
42 The expression in s.25(f) "reasonable grounds to believe" is used in s.25(b), (c), (d) and (e), although the belief in each of those sub-paragraphs is related to past facts. In s.25(f), the grounds of the requisite belief must relate to a matter in prospect but one based on an assessment of existing facts, namely, the prospective outcome of a forensic procedure if undertaken.
43 It is clear that an applicant for a final order under the Forensic Procedures Act must place before the magistrate information which enables the latter to be able to assess whether or not there are reasonable grounds for the asserted belief. The mere assertion or contention in an affidavit that there are reasonable grounds to believe that a forensic procedure might produce evidence tending to confirm or disprove that the suspect committed the relevant offence is clearly insufficient: see Orban (supra) at [40]. The factual foundation constituting reasonable grounds for the specified belief must be given with sufficient particularity to permit an authorising magistrate to be in a position to determine whether there are reasonable grounds to believe that the forensic procedure might produce the outcome or result referred to in the sub-paragraph.
44 Whilst the factual matters set out in paragraph 2 to the first defendant's affidavit in support of the application disclosed factual matters that constitute reasonable grounds for believing that the plaintiff was a "suspect" within the meaning of s.3 of the Act in relation to a prescribed offence, they do not, in my opinion, establish matters that were necessary to satisfy the provisions of s.25(f).
45 Section 25(f) focuses attention upon the existence of reasonable grounds for a belief that a forensic procedure can, in a given situation, produce evidence that either tends to confirm or disprove that the suspect committed the relevant offence. In order to satisfy that pre-condition, there is a need in an application of the kind in question for an applicant to identify the basis upon for the belief that such a forensic outcome might be produced. The technique of DNA identification is, of course, one employed on the basis that there, in fact, exists forensic material upon which identification can be made or disproved. In an article, DNA Identification in the Criminal Justice System, by Jeremy Gans and Gregor Urbas (May 2002), Australian Institute of Criminology Trends and Issues and Crime and Criminal Justice, the learned authors discuss the technique of DNA identification involving, as it does, the essential comparison of DNA from two bodily samples, crime scene DNA and samples taken of other human bodily material:-
"… contemporary profiling techniques can generally be used on such tiny samples as the root of a pulled hair, saliva on a cigarette butt, a square-centimetre blood stain, skin cells from clothing or three micrograms of semen from a vaginal swab; standard or alternative techniques will sometimes succeed on other, less optimal, samples such as shed hair or skin cells from a handled object …"
46 The evidence before the magistrate in the application before him failed to identify the basis for the claimed belief that DNA matching could be undertaken. Specifically, there is no information as to the taking or availability of crime scene DNA material from the victim's premises. There are references to the possibility that a meal or meals had or may have been half eaten by someone and there is reference to the fact that a telephone call may have been made by the plaintiff. However, what is left to speculation is the existence of any relevant DNA crime scene sample(s) or material that could provide the reasonable grounds for the belief stated in and made necessary by the provisions of s.25(f). The existence and nature of any such samples or material, if they existed, would, no doubt, be readily ascertainable by or known to those who have been involved in the investigation.
47 I do not consider, as was argued on behalf of the first defendant, that the pre-condition specified in s.25(f) sets such a low threshold that the reference to "might produce evidence" meant that the magistrate need only be satisfied that there existed a potential outcome envisaged by s.25(f) without more. The inclusion of the expression "reasonable grounds to believe" means, there must be more than mere speculation or more than a mere theoretical possibility that evidence referred to in the provision might be produced. A factual foundation sufficient to constitute reasonable grounds for such belief must be demonstrated. The factual material in paragraph 2 of the affidavit, as I have earlier stated, was insufficient and was not directed to satisfying the pre-condition to s.25(f). It was directed and limited to satisfying the pre-condition stated in s.25(c).
48 In determining the correct interpretation and application of the provisions of s.25, it is, of course, necessary to bear in mind practical issues surrounding the availability of forensic procedures to authorised persons. In other words, an interpretation which would in any way frustrate the purpose of the legislature is, of course, one that must be avoided.
49 The first defendant submitted, as earlier mentioned, that the Act does not require material found at the crime scene to already have been analysed at the time of the making of an order for a forensic procedure. It was emphasised that an application is made whilst an investigation is still in progress and that "the spirit of intendment of the Act, particularly based on the working of s.25(f), is such to investigate that orders of this nature might be made where the factual framework is relatively thin on the ground".
50 An interpretation of a statutory provision that requires factual material to be placed before a magistrate on a forensic procedure application is not one that works against a practical application of the Act itself. The particular difficulty in the present matter arises simply from the absence of information or material that establishes relevant primary factual matters. In Orban (supra), for example, there existed specific material which established primary facts as to:-
