"(a) That at approximately 23.51 hours on3rd February 2004 , PC Rowland saw two vehicles, one of which was the appellant's Jaguar, leaving the car park of the public house known as the Hare and Hounds. He decided to stop both vehicles and did in fact do so in Broad Road. At this point PC Rowland asked the appellant whether he had been drinking. "(b) Following the appellant's answer PC Rowland carried out a roadside breath test. This proved positive and the appellant was arrested, cautioned and then conveyed to the police station. "(c) PC Fraser carried out the Intoximeter procedure at the police station in accordance with the form MGDDA. PC Rowland was also present throughout. PC Fraser asked the appellant set questions. His replies were noted on the form MGDDA by PC Rowland. The machine had been checked and no problems were present. PC Fraser explained the procedure for providing the specimens and the appellant duly provided two specimens of breath. The machine provided a computer print-out showing two readings, the lower of which was 52 microgrammes in 100 millilitres of breath. PC Fraser told the appellant he was therefore over the prescribed limit."
"PC Rowland gave evidence as follows: He stopped the appellant's vehicle on the night of2nd February 2004 on Broad Road, Braintree, after he had seen him leaving the car park of the Hare and Hounds public house. He did so because he suspected the appellant, who was the driver of the vehicle, had been drinking and wanted confirmation. "
"... the rights of the public to be protected from drink-drivers and the purpose of the legislation pertaining to this case."
"(a) Were we right in law to hold that there had been no breach ofCode C of the Police and Criminal Evidence Act 1984 Codes of Practice? "(b) Were we right to determine that there was admissible evidence on which we could conclude the proportion of alcohol in the appellant's breath is 52 microgrammes in 100 millilitres of breath and exceeded the prescribed limit? "(c) Did we err in law in rejecting the appellant's contention that they were not entitled to convict because there was no evidence of calibration of the Intoximeter machine? "(d) Were we entitled to take into account the purpose of the drink-drive legislation when considering the evidence and the conduct of the appellant's cross-examination of the witnesses during the trial?"
"Where a constable in uniform has reasonable cause to suspect (a) that a person driving a motor vehicle on a road or other public place has alcohol in his body he may, subject to section 9 of this Act require him to produce a specimen of breath for a breath test."
"It was clearly the intention of the legislature, in enacting subsection (5), that the defendant should be provided in advance of the hearing with the information recorded on the automatically produced statement. This information includes not only the results of the measurement effected by the instrument of the two specimens of breath -- results of which the defendant might otherwise have only an imperfect recollection -- but also, and of even greater importance, the results of the self-calibrating exercise which the instrument carries out both before and after the two specimens of breath are provided. If the measurement produced by the instrument is to be relied on by the prosecution, it is clearly vital for the prosecution to establish that the instrument was properly calibrated. "
"... it had to be accompanied by evidence of the calibration of the machine, both before and after the specimen of breath had been provided by the defendant and of the date and time when the test was taken. The witness also had to be in a position to inform the justices that the figures for calibration which he saw, if he did, on the display panel were within permissible limits and that therefore the device was functioning properly. "
"For my part I would accept that as clearly sufficient evidence, albeit perhaps in shorthand, that he had considered the calibration readings amongst others, and was telling the court that the machine was reliable and was working properly and he went on to give the actual reading of 51 microgrammes. The time for the defence to challenge that aspect of the case, that is, the reliability of the machine, if they had any basis at all for doing so, was then. They did not do so and that evidence went unchallenged."
"It seems that the position is clear.Section 16 of the Road Traffic Offenders Act 1988 enables, and it is a permissive section, the prosecution to rely on the documents produced by the machine provided they do so in the prescribed fashion. But it is clear that the prosecution may also rely on the direct evidence of the officer who administered the breath test at the police station to give the reading based on his observation of the figures on the machine. If he is going to do that, he must give evidence that the machine was working properly and appeared to be reliable at the time. That is a matter of basic common sense which the courts have underlined. "
"We have been referred to three cases where this court has said that, if a police officer gives oral evidence of the result of a Lion Intoximeter test but does not identify the print-out and produce it to the court, he must give evidence of the calibration of the machine both before and after the test was taken. Those cases are Owen v Chesters, Morgan v Lee and Denneny v Harding. In my judgment it does not follow that the officer must in terms give evidence of what the actual calibration results were. Here the officer's evidence-in-chief is summarised in paragraph 3 of the case as follows: 'He stated that at the time of the test all of the readings showed the machine was working properly.' That is no doubt a summary. We do not know the actual words used by the officer giving evidence, but we must accept it as an accurate and comprehensive summary. If the defence wanted to test that evidence, they should have explored the point in cross-examination. It would seem that, if the defence had done so, the sergeant could have given some answers. He had the print-out with him, but no questions were asked. In my judgment on the sergeant's evidence here there was a case to answer and the justices were entitled to find the offence proved. "
