Of course, there will be difficulties in drawing lines in specific cases, but that happens every day in the law.
19 However, the mere fact that the prosecuting authority's intention/proposal is conditional will not suffice to relieve it of the obligation of early disclosure. If that were the law, the scheme would miss several of its intended targets (cf West at 654-5). I agree with O'Keefe J's remarks quoted above that a restrictive approach should not be adopted to the meaning or ambit of the statute. A fortiori, given the liberal discretions to waive non-compliance on appropriate terms (see West at 656-7). It is commonplace that the moving party in civil or criminal proceedings will discover that it becomes unnecessary to call every intended witness or to tender every proposed exhibit. In criminal cases a late plea may remove the need for any matter to be proved formally. Other issues may go away in light of formal admissions, judicial rulings, or the simple ebb and flow of adversary litigation. A conditional intention may still be a formed intention, as with the statement "I intend to go to the cricket if it is fine" (see generally K Campbell, "Conditional Intention" (1982) 2 Legal Studies 77).
20 Where the very admissibility of substantive evidence depends on proof of certain matters, then the latter proofs are as much an essential part of the ideal prosecution brief as the former. The "evidence that the prosecution intends to adduce in order to prove the commission of the offence" thus includes evidence both of facts in issue and evidence tendered solely in proof of the same (cf Evidence Act 1995, s55(2)(b)). This evidence will thus include facts touching "preliminary questions" as defined in s189 of the Evidence Act. Since an offence can only be proved by admissible evidence (leaving aside judicial notice, formal admissions and the like, which are rare) it may be inferred that the prosecuting authority would intend to adduce only admissible evidence. To the extent that admissibility itself turns on proof by "documents regarding the evidence" then the sinews of such proof are themselves a necessary part of the prosecution brief.
21 Of course, the formal admission of a fact will mean that is no longer in issue. Likewise, the waiver of a necessary method of proving a fact in issue may relieve the proponent of the need to do so. If such circumstances occur before the time for serving the brief of evidence, a prosecuting authority may properly form the intention not to call evidence on such matters, with consequential lightening of the load imposed by s66B(1).
22 It will not, however, suffice that the prosecuting authority thinks or hopes that formal proof may be dispensed with. A defendant is entitled to put a prosecutor to strict proof and a prosecuting authority is not entitled to assume otherwise without a firm foundation. (The Criminal Procedure Amendment (Pre-Trial Disclosure) Act 2001 qualifies this proposition in certain respects as regards complex trials in the Supreme Court and District Court.)
23 The claimant submitted that in the present case it was not the intention of the prosecuting authority to adduce the evidence of the warrants "unless the defence took the point". There are several difficulties with this. First, it does not qualify as a question of law. Secondly, the submission is pure assertion in view of the absence of evidence on the topic. Thirdly, the submission fails to grapple with the likelihood, verging on certainty, that the particular prosecutor must have intended to tender the warrants and evidentiary certificates, if necessary to do so. Such necessity might arise if the defendant absented herself from the hearing (cf Hodder (1986) 33 A Crim R 295) or if she attended and exercised her right to put the Crown to a strict proof. Such conditional intention was sufficient to engage the duty of early disclosure. In my view, it is indistinguishable from the intention of the person who says : "I will go to the cricket tomorrow if it is fine, unless the test match is over before then". Indeed, the cricket-lover's intentionality strikes me as more tentative than that of the prosecutor who, unless totally uninformed, must have realised both the necessity to tender the warrants unless the need to do so was waived and that there was no likelihood that waiver would be addressed until the day of trial.
24 In my view, O'Keefe J was correct in holding that no error of law was established.
25 The relevant warrants and evidentiary certificates were essential preconditions to admissibility of the tapes and other evidence of the intercepted conversations for the following reasons:
