[2003] VSCA 81
respondent. Appeal dismissed. Order of the Trial Division allowing the DPP's appeal and remitting the matter to the Magistrates' Court affirmed. Costs consequences in the courts below stand as ordered...
Luff was charged with drink-driving after an incident; a station breath test recorded 0.189% BAC. The magistrate accepted he was the driver but dismissed the alcohol charges because she was not satisfied the breath-analysis machine had been properly operated. The DPP (on behalf of the police informant) appealed to the Trial Division which allowed it and sent the case back to the Magistrates' Court. Luff appealed to the Court of Appeal. The Court of Appeal dismissed his appeal. It held (1) the DPP could properly bring the appeal on behalf of the police informant, the Court being able to infer the informant's wish to appeal from the circumstances and affidavits, and (2) the magistrate erred in law by treating proof that the breath analyser had been properly operated as a prerequisite for conviction under s 49(1)(f); s 49(4) places on the accused the onus to prove on the balance of probabilities that the instrument was not in proper working order or properly operated. The matter returns to the Magistrates' Court for rehearing consistent with these principles.

Short version: At about 12.30 a.m. on 5 December 1997 the appellant's utility vehicle mounted a kerb and damaged property in South Yarra. Police attended, conducted a preliminary breath test and took the appellant to the Prahran Police Station where at 3.07 a.m. an authorised operator used a breath analysing instrument and recorded a blood alcohol concentration of 0.189% (Vincent JA at [16], [19]). The appellant was charged under the Road Safety Act 1986 with, among other things, driving with more than the prescribed concentration of alcohol (s 49(1)(b)) and furnishing a breath sample within three hours yielding a reading above the prescribed concentration (s 49(1)(f)); other non-alcohol charges were also laid (Vincent JA at [22]).
After a three-day hearing in the Magistrates' Court the magistrate accepted the appellant was the driver but dismissed the two alcohol-related charges because she said she could not be satisfied that the breath analysing instrument had been properly operated (her detailed reasoning appears at [29]). The Director of Public Prosecutions (DPP), purportedly acting on behalf of Senior Constable Cole (the informant), appealed to the Trial Division which allowed the appeal, set aside the Magistrates' Court order and remitted the matter to the Magistrates' Court for rehearing (Vincent JA at [33], [36]). The appellant (Luff) then appealed to the Court of Appeal against the Trial Division decision. The Court of Appeal dismissed his appeal and affirmed the Trial Division's order remitting the matter to the Magistrates' Court (Vincent JA at [143]; Callaway JA at [2], [11]).
Two discrete legal problems were decisive: (1) whether the Trial Division had jurisdiction to hear the DPP's appeal under s 92 Magistrates' Court Act 1989, in particular whether there was adequate evidence that the informant 'wished to appeal' so as to allow the DPP to act on his behalf; and (2) whether the magistrate had applied the correct legal test in dismissing the alcohol charges by treating proof of proper operation of the breath analyser as an element the prosecution had to prove for s 49(1)(b) and, crucially, for s 49(1)(f) (Vincent JA at [47], [95], [105], [117]).
Two pillars underpinned the Court of Appeal's decision.
Jurisdiction under s 92: The Court accepted that the statutory provision requiring the DPP to bring an appeal on behalf of a police informant (s 92(2)) did not invariably demand a formal affidavit by the informant expressly stating he or she 'wished to appeal'. Rather, the Court explained that the tribunal may be satisfied on the balance of probabilities that the informant wished to appeal by the circumstances and communications before it, and by reasonable inference from the way the DPP became involved. The Court examined the affidavits of the OPP solicitor (Castle) stating that the Deputy Commissioner had asked the DPP to bring the appeal on behalf of the informant, and the informant's own affidavit indicating engagement with the process, and concluded those facts allowed the Trial Division properly to infer that the informant wished to appeal (Vincent JA at [63], [69], [75]-[84]; Callaway JA at [5], [8]). The Court therefore found no jurisdictional error.
Burden of proof and statutory scheme on breath-analysis: The Court carried out a textual and purposive analysis of Part 5 of the Road Safety Act. It concluded that s 49(1)(b) (driving while a prescribed concentration is present) simply requires prosecution proof beyond reasonable doubt of that essential element; the statute does not say the prosecution must prove the instrument was properly operated. By contrast, s 49(1)(f) expressly incorporates the breath analyser result into the offence but s 49(4) is a statutory defence that places upon the accused the burden on the balance of probabilities of proving the instrument was not in proper working order or was not properly operated. The Court followed Furze v Nixon in treating s 49(4) as a clear legislative allocation of the onus (Vincent JA at [95]-[105], [112], [120], [127], [133], [136], [143]). On this basis the magistrate erred in law by treating proof of proper operation as a prosecutorial obligation for s 49(1)(f), and also by treating that proof as necessary for conviction under s 49(1)(b) in the particular manner she did (Vincent JA at [120], [127]).
The Court therefore affirmed the Trial Division's approach: the remitter to the Magistrates' Court was appropriate so that the magistrate could apply the correct legal tests and re-evaluate the evidence, including consideration of whether the accused could discharge the s 49(4) defence on the balance of probabilities (Callaway JA at [11]; Vincent JA at [143]).
Before this decision (and consistent with it), the controlling rule on s 49(1)(f) had been stated in Furze v Nixon: s 49(4) places upon the accused the onus of proving that the breath analyser was not properly working or was not properly operated. The Court in Luff reaffirmed and expressly followed Furze, rejecting submissions that Furze was obiter or per incuriam (Callaway JA at [5]). The Court therefore cemented the position that the statutory defence in s 49(4) is the mechanism by which reliability of machine operation is challenged for s 49(1)(f) charges.
As to s 49(1)(b), the Court reiterated that the prosecution's obligation is to prove the essential element (the presence of the prescribed concentration) beyond reasonable doubt. If the only evidence of that element is an analysis that is shown to be unreliable, the prosecution may fail; but that is not the same as a rule that the prosecution must affirmatively prove proper operation in all cases (Vincent JA at [95]-[117]).
On procedure under s 92 Magistrates' Court Act, the Court clarified that the DPP's power to bring an appeal on behalf of a police informant may properly be exercised where the Court is satisfied on the balance of probabilities that the informant wished to appeal; formal sworn statements are not indispensable in every case (Vincent JA at [63], [69], [75]-[84]).
After Luff, practitioners should assume the following:
Statutory mechanism for police appeals (Vincent JA at [47]):
Magistrate's pivotal reason for dismissal (quoted at [29]):
Onus under s 49(4) (Vincent JA quoting Furze at [105]):
Effect of operator evidence under s 58(4) (Vincent JA at [112]):
Parliament's purpose for Part 5 (Vincent JA at [136], [140]):
The Luff decision is directly engaged whenever:
Practical triggers for litigators: (a) where defence counsel attacks operator credibility in cross-examination as in this case; (b) where the accused gives notice under s 58 so the certificate loses its conclusive effect; (c) where the DPP brings an appeal purportedly on behalf of a police officer informant and the appellant challenges the DPP's standing or the informant's wish to appeal.
This decision expressly follows Furze v Nixon and reinforces that authority as the binding approach in Victoria on s 49(1)(f) and s 49(4). Callaway JA also addressed suggestions that Furze might have been per incuriam and rejected them (Callaway JA at [5]), thus discouraging attempts to displace Furze on that basis at the Court of Appeal level. The Court's reasoning aligns with a statutory and purposive approach: treat s 49(4) as a specific legislative allocation of burden.
The Court signalled willingness to rely on appropriate inferences of the informant's wish to appeal where the factual matrix supports such an inference, referencing Day v Hunter and Mallock v Tabak in that context (Vincent JA at [63], [84]). The decision also made clear that courts need not adopt a rigid affidavit-only approach in every case to prove the informant's wish; the focus is whether the Trial Division was satisfied on the balance of probabilities.
Practitioners should therefore expect courts in Victoria to treat Luff (and Furze) as authoritative on allocation of burden in s 49(1)(f) matters, while still allowing fact-sensitive assessments at first instance about operator credibility and the practical effect of s 58(4) evidence.
Degree of contrary evidence required to displace s 58(4) averments: Vincent JA observed that while s 58(4) remains effective until contradicted, "empty or clearly unreliable" averments would require little rebuttal [120]. The Court did not delineate a precise threshold for when operator evidence becomes so unreliable that it cannot be treated as proof. That leaves an evidentiary question for lower courts: how much and what kind of contrary evidence will suffice to nullify s 58(4) proof?
Interaction between s 49(1)(b) and s 48(1)(a) presumption: Vincent JA noted the statutory presumption in s 48(1)(a) (that a concentration proven within three hours is presumed to have existed at the time of driving) but observed that the presumption only arises if the identified concentration is established as present within the prescribed period [95], [148]. The interplay between proof of concentration, challenges to analyser reliability, and the operation of the presumption may produce complex factual inquiries on remitter.
Extent of permissible inference about an informant's wish to appeal: Luff permits inference from circumstances and communications; what specific types of communications or institutional practice will suffice is unresolved. Although the Court accepted the OPP affidavit and the informant's conduct as adequate here, future cases may test the limits of inference, particularly where institutional actors (Deputy Commissioner, prosecutors) intervene.
Comparative and human-rights questions: Callaway JA noted later English decisions touching related issues (Sheldrake, Attorney-General's Reference) and differences posed by rights frameworks, but the Court did not explore their impact on Victorian procedure [5]. If human-rights-style arguments about procedural fairness and allocation of burdens are pressed in future, the local statutory scheme may be tested against broader rights-oriented jurisprudence.
In short, Luff clarifies the allocation of burden under the Road Safety Act and the practical operation of s 92 appeals in Victoria, but leaves scope for detailed evidentiary work at first instance on operator credibility and for doctrinal development as new factual scenarios arise.
[ 2003] VSCA 81
Driving offences - Appellant charged with having more than prescribed concentration of alcohol present in blood - Road Safety Act 1986, s.49(1)(b) and (f) - Whether prosecution obliged to prove breath analysing instrument properly operated - Charges dismissed and appeal brought by Director of Public Prosecutions - Magistrates' Court Act 1989, s.92 - Whether trial judge entitled to hold that informant "wishe[d] to appeal" - Furze v. Nixon [2000] VSCA 149; (2000) 2 V.R. 503 applied - Appeal dismissed.
"Charge 1 - Driving or being in charge of a motor vehicle while more than the prescribed concentration of alcohol is present in his blood contrary to s.49(1)(b) Road Safety Act 1986; Charge 2 - Being within three hours after driving or being in charge of a motor vehicle and furnishing a sample of breath for analysis by a breath analysing instrument under s.55(1) Road Safety Act 1986 and result of the analysis recorded or shown by the breath analysing instrument indicated more than the prescribed concentration of alcohol was present in his blood contrary to s.49(1)(f) Road Safety Act 1986; Charge 3 - Careless driving contrary to section 65 Road Safety Act 1986; Charge 4 - Failing to stop after an accident causing damage to property contrary to ; Charge 5 - Failing, after an accident causing damage to property, to give his name and address to the owner of the damaged property contrary to ; and Charge 6 - Failing, after an accident causing damage to property, to report the accident to the police contrary to ."
"As I say, I am perfectly satisfied that he is the driver.[6] I am not however perfectly satisfied that he had a breath alcohol reading of 0.189. This is why I say it's a most unusual case. Let me just read some of the evidence directly that [the operator] gave. You will recall that when he gave his evidence I gave the witness permission to refer to his statement which contained the proforma - we'll call it the proforma proof part of a breath operator's statement. I gave him that permission over objection from counsel and I still - I certainly don't believe that that was improper. I think it's perfectly proper to give leave to a witness to refer to his statement, however there was an objection at that time. He continued with his evidence and then in cross-examination he said that he had read his notes before he gave evidence, though there was a lot of the formal matters that he was unable to recall. He agreed that the last page of his notes contained the formal proofs. He disagreed that his mind went blank in evidence in chief just before he got to those important parts. He denied a number of other suggestions which we don't have to - I don't have to bother about. He did say that he had had a blank and that's why he hadn't been able to recall the - which led, of course, for me giving him leave. He couldn't remember the numbers on the machine, though he remembered the machine. He was asked - he gave evidence that he complied with the regulations. He then gave this piece of evidence when asked. He was asked what were the exact regulations he complied with. He said, 'I don't know the exact regulations and what they say. I can't remember the exact one. I can't recall which ones they are and if I have complied.' When put to him this question, 'You can't give evidence that you did comply with them', he said, 'That needs to be assessed by the court', and he denied he was being evasive on that point. He wasn't being evasive. He had been cornered and the reality is if he doesn't know what regulations he complied with, I can't be satisfied he complied with the regulations. He doesn't know what they are, he couldn't say what they are. It leaves me in the position where I cannot be satisfied that the test result obtained was obtained as a result of a properly operated machine by an authorized officer[7] and those 0.05 charges will be dismissed accordingly. As I have indicated, I find no difficulty in the fact that - well, I have no difficulty in finding that the defendant was the driver on the night and the remaining charges are found proved."
"[T]hat the learned judge of the Trial Division (hereafter referred to as 'the trial judge') erred in law as follows; 1. By holding that under the circumstances the appeal was competent pursuant to section 92 of the Magistrates' Court Act 1989. 2. By failing to hold that under the circumstances there was no evidence that section 92(2) of the Magistrates' Court Act 1989 had been complied with insofar that: (a) there was no competent evidence before the Court that the informant 'wished to appeal'; and/or (b) there was no competent evidence before the Court that the appeal was brought by the Director of Public Prosecutions on behalf of the informant. 3. By holding (if she did so hold) that: (a) it could be assumed under the circumstances that (a stranger to the proceedings) the Deputy Commissioner (Operations) of Police did not of his own accord initiate the request to the Director of Public Prosecutions to bring the appeal on behalf of the informant; and/or (b) that it was open to infer that the informant brought the matter to the attention of the Deputy Commissioner in order that the procedure laid down by section 92(2) of the Magistrates' Court Act 1989 for an appeal might be set in motion; and in so doing the learned trial judge applied the wrong test. 4. By failing to hold that in the absence of evidence to the contrary it was not open to assume or infer that: (a) the informant 'wished to appeal'; and/or (b) the appeal was not brought by a stranger to the proceedings; and/or (c) the requirements of section 92(1) of the Magistrates' Court Act had been complied with; and/or (d) the requirements of section 92(2) of the had been complied with. 5. By holding that: (a) the informant had shown by his initiation of the appeal process laid down under the that he 'wishes to appeal'; and (b) no other conclusion was possible on the facts; and in so doing the learned trial judge applied the wrong test. 6. By failing to hold that under the circumstances it was not open to find that: (a) the informant had in fact initiated the appeal process; and/or (b) 'wished to appeal'; and/or (c) the appeal had not been brought by a stranger or strangers to the proceedings (to wit, the prosecutor in the lower Court and/or the Deputy Commissioner of Police); and/or (d) the Director of Public Prosecutions had brought the appeal on behalf of the informant. 7. By holding that (under the circumstances) the Court had jurisdiction to hear the appeal.
"92. Appeal to Supreme Court on a question of law (1) A party to a criminal proceeding (other than a committal proceeding) in the Court may appeal to the Supreme Court on a question of law, from a final order of the Court in that proceeding. (2) If an informant who is a member of the police force wishes to appeal under sub-section (1), the appeal must be brought by the Director of Public Prosecutions on behalf of the informant."
"The terms of this sub-section make it clear that there is no magic in the words `any person who feels aggrieved' and that so far as criminal and quasi criminal matters are concerned, any party to the proceedings in the court below falls within them if he is dissatisfied with the decision given in that court. Consequently, if the informant or defendant in any such proceedings seeks an order to review the decision given therein, he takes his place as a `person who feels aggrieved', because by so doing he shows in the most unequivocal manner his dissatisfaction with the decision sought to be reviewed. What brings him within the class is the fact that he is a party to the proceedings below and, therefore, really interested therein, combined with the fact that he has shown by his application for an order nisi to review his dissatisfaction with the order sought to be reviewed."
In the later case of Jennings v. Newlan[10], an Order to Review was sought by the police prosecutor and not the informant in a charge laid against the respondent in the Magistrates' Court. Tadgell, J. held that the prosecutor had not been "shown to have had any special interest in the proceedings or their outcome"[11] and therefore did not fit the statutory description of "a person who feels aggrieved" by the dismissal of the information. After rejecting, for a number of reasons, an application made by the applicant in the proceeding to substitute as the "aggrieved" party the informant in the court below, he concluded by saying:
"Quite apart from all that, there is no evidence of any kind which indicates the attitude of the informant to his now being joined. I do not know why he did not apply for an order to review in the first place. The omission might have been accidental but I am not to assume that it was. Indeed, I know nothing of the informant at all."[12]
"1. I am a solicitor employed in the Office of Public Prosecutions, Victoria and my duties include receiving on behalf of the Director of Public Prosecutions, requests by the Deputy Commissioner (Operations) of Police on behalf of members of the police force, to bring appeals to the Supreme Court on questions of law pursuant to section 92(1) Magistrates' Court Act 1989.
...
3. The Director of Public Prosecutions has been asked by the Deputy Commissioner (Operations) of Police to bring an appeal on behalf of the Informant under section 92(1) Magistrates' Court Act 1989 from the final order made on 6 September 2000 by Ms. J. Crowe, Magistrate whereby she dismissed charges 1 and 2 in this matter.[13]
4. I have been directed by the Director of Public Prosecutions to bring an appeal on behalf of the informant under section 92(1) Magistrates' Court Act 1989 from the final order made on 6 September 2000 by Ms. J. Crowe, Magistrate whereby she dismissed charges 1 and 2 in this matter."
"It is to be expected in the context that the persons on whom the duty is imposed are instructed in and know their duty and the conditions of its exercise.
...
The situation is one in which the mind may be satisfied of the likelihood of correct observance of [s.92], and of the unlikelihood of lack of observance of its conditions."
First, driving a motor car in circumstances encompassed by s.49(1)(b) of the Road Traffic Act 1986.
"(1) A person is guilty of an offence if he or she -
...
(b) drives a motor vehicle or is in charge of a motor vehicle while the prescribed concentration of alcohol or more than the prescribed concentration of alcohol is present in his or her blood;"
It is to be noted that under this provision the prosecution bears the onus of establishing that the concentration of alcohol present in a driver's blood equals or exceeds the prescribed concentration.[15] However, there is, of course, no requirement that a breath analysing instrument be used to ascertain that concentration. Indeed, it may be ascertained by other means.[16] Nor is there any obligation cast upon the prosecution, in a case where a breath analysing instrument is employed, to prove that the machine was properly operated. If, however, a reasonable doubt can be seen to exist concerning the reliability of the analysis, a magistrate may well not be satisfied that the commission of the offence has been established. That is not because there is an onus cast upon the prosecution to establish that the instrument has been properly operated but because they have failed to prove the presence of an essential element of the offence itself.
Second, he was charged with an offence under s.49(1)(f) which applies to a driver who:
"(f) within 3 hours after driving or being in charge of a motor vehicle furnishes a sample of breath for analysis by a breath analysing instrument under section 55 and - (i) the result of the analysis as recorded or shown by the breath analysing instrument indicates that the prescribed concentration of alcohol or more than the prescribed concentration of alcohol is present in his or her blood; and (ii) the concentration of alcohol indicated by the analysis to be present in his or her blood was not due solely to the consumption of alcohol after driving or being in charge of the motor vehicle;
...
(4) It is a defence to a charge under paragraph (f) of sub-section (1) for the person charged to prove that the breath analysing instrument used was not on that occasion in proper working order or properly operated."
"... it was no part of the prosecution case to prove that on the relevant occasion the breath analysing instrument was either in proper working order or properly operated. We have set out already s 49 (1) (f) which constitutes the offence with which the appellant was charged. Section 49 (4) reads as follows: 'It is a defence to a charge under paragraph (f) of sub-section (1) for the person charged to prove that the breath analysing instrument used was not on that occasion in proper working order or properly operated.' This seems to be a plain legislative prescription casting upon the person charged the onus of proving that the breath analysing instrument was not, on the relevant occasion, in proper working order or properly operated.[18] We have said why, in our opinion, the certificate which was tendered in evidence was not (contrary to the judge's opinion) even prima facie evidence that the machine was properly operated; but in the light of s 58(4), if the contrary was to be proved, it was a matter for the appellant."
, the magistrate regarded that evidence as unsatisfactory.[21]
"It leaves me in the position where I cannot be satisfied that the test result was obtained as a result of a properly operated machine by an authorized officer."[23]
The judge in the Trial Division correctly found that in determining the matter on this basis, her Worship fell into error.
"The purposes of this Part are to - (a) reduce the number of motor vehicle collisions of which alcohol or other drugs are a cause; and (b) reduce the number of drivers whose driving is impaired by alcohol or other drugs; and (c) provide a simple and effective means of establishing that there is present in the blood of a driver more than the legal limit of alcohol."
[2] I do not overlook the more explicit language of s.48(1AC) and (1A), inserted some years after s.49(4) was enacted. In England such questions are complicated by the European Convention for the Protection of Human Rights and Fundamental Freedoms. See, for example, Sheldrake v. D.P.P. [2003] 2 All E.R. 497 and Attorney-General's Reference No. 4 of 2002 [2003] EWCA Crim. 762. Counsel informed us that leave to appeal to the House of Lords has been granted in both those cases. Paragraphs [9]-[10] of the former and para. [23] of the latter strongly support the construction of s.49(4) adopted in Furze v. Nixon.
[3] (1992) 16 M.V.R. 461 especially at 467-468.
[4] Compare the reasons in the Trial Division at [27].
[5] The proceeding which was conducted over 24, 25 and 26 May 2000 was tape-recorded but the recordings were preserved for only three months in accordance with the policy of the Court. There is some conflict in the affidavits before this Court concerning the precise state of the evidence that accordingly cannot be resolved. The situation is rendered more uncertain as, for some unexplained reason, the magistrate did not deliver judgment until 6 September 2000 and, it appears, did not have complete notes.
[6] The appellant asserted that he could not recall whether he had driven the car on the night in question although there was evidence that he had admitted that this was the case when initially spoken to by Constable Cole at his home.
[7] It had been conceded in the course of the hearing that the operator was duly authorized and I do not understand that it has ever been suggested that the instrument itself was not in proper working order.
[8] These sections respectively conferred upon "a person who feels aggrieved" a limited right to apply to a judge of the Supreme Court for an Order to Review convictions entered or orders made in the Court of Petty Sessions (Justices Act, s.155(1)) or the Magistrates' Court (Magistrates' Court Act 1971).
[9] [1964] VicRp 109; [1964] V.R. 845 at 847-48.
[13] The judge in the Court below reasonably found in relation to this passage that
"it can be assumed that the Deputy Commissioner (Operations) of Police did not of his own accord initiate the request to the Director of Public Prosecutions to bring this appeal on behalf of the informant .... The informant was the person within the Victoria Police responsible for the matter. It can be inferred that it was he who was initially responsible for the matter being brought to the attention of the Deputy Commissioner in order that the procedure laid down by sub-s.92(2) of the Magistrates' Court Act for an appeal might be set in motion."
[14] [1977] VicRp 7; [1977] V.R. 78 at 85.
(a) if it is established that at any time within 3 hours after an alleged offence against paragraph (a) or (b) of section 49(1), a certain concentration of alcohol was present in the blood of the person charged with the offence it must be presumed, until the contrary is proved, that not less than that concentration of alcohol was present in the person's blood at the time at which the offence is alleged to have been committed;"
The presumption with respect to the concentration of alcohol present in the blood of the charged person does not arise unless identified concentration is established as present within the prescribed period. It may well be in the present matter that, dependent upon the conclusions ultimately reached concerning the reliability of the analysis, that no such presumption would arise.
[17] [2000] VSCA 149; (2000) 2 V.R. 503 at 513.
[19] "s.58(4) Evidence by a person authorised to operate a breath analysing instrument under section 55 - (a) that an apparatus used by him or her on any occasion under that section was a breath analysing instrument within the meaning of this Part; (b) that the breath analysing instrument was on that occasion in proper working order and properly operated by him or her; (c) that, in relation to the breath analysing instrument, all regulations made under this Part with respect to breath analysing instruments were complied with -
is, in the absence of evidence to the contrary, proof of those facts."
21] I suspect that the operator who, it appears, gave evidence on such matters for the first time, may have been quite overawed by the experience. That possibility, whilst understandable, does not alter the effect or reliability of the evidence given by him.
