"It is denied that EC/IR No. 03043 is an approved device. It uses a fundamentally different method from the exemplars for detecting where an analysis should be taken and, without prejudice to the generality of the foregoing, it uses different slope parameters and different slope times. These are either software changes or akin to software changes. Other alterations have taken place such as a new circuit board, and the DPP is put to proof that the software is still UK 5.23 and not, for example, 5.25 as in the EC/IR at Andover."
"We were of the opinion that there was evidence on which we could find that the appellant drove a motor vehicle on a road after consuming so much alcohol that the proportion of it in his breath exceeded the prescribed limit. We took into account the totality of the circumstances and found that: (1) The Intoximeter EC/IR (03043) is of a type approved by the Secretary of State. (2) The Intoximeter EC/IR did have a manual changeover valve but in 2001 it had a blanking plug fitted. (3) There was no evidence that there was mouth alcohol present at the time when the two samples were taken. (4) There was no evidence that the appellant suffers from reflux or did suffer from reflux on22nd February 2002 . (5) The EC/IR (serial number 03043) showed no malfunction. (6) Under all the circumstances we were satisfied that the reading provided by Intoximeter EC/IR (serial number 03043) was reliable."
"Were we wrong to refuse to issue a witness summons to compel the attendance of Mr Rudrum, the Forensic Science Service advisor to the Home Office on type approval?"
"Were we wrong to refuse the appellant's application to adduce two letters written by Mr Rudrum and the Managing Director of Intoximeters UK Ltd relating to the Banbury EC/IR as business documents undersection 24 Criminal Justice Act 1988 ?"
"Where the presumption that an Intoximeter is reliable is challenged by expert evidence (with or without evidence from the defendant/others as to the amount of alcohol consumed): (1) Magistrates are only concerned with the particular Intoximeter device used (for example in Mr Brown's case EC/IR instrument number 01384). It is thus no part of their function to consider whether the Intoximeter EC/IR should have received the approval of the Secretary of State. (2) Magistrates will be fully aware of the strength of the evidence provided by a printout, taken from an approved device, of a specimen of breath. The assumption ins.15(2) of the Road Traffic Offenders Act 1988 is an assumption that the proportion of alcohol in the relevant specimen was not less than the proportion of alcohol at the time of the offence. In the case of a breath specimen there is a presumption of law that the machine is reliable. If that presumption is challenged by relevant evidence, the Magistrates will have to be satisfied that the machine provided a reading upon which they can rely before making the assumption. (3) Magistrates will no doubt look with a critical eye (see Lord Griffiths in Cracknell v Willis, supra, at 468E) to see whether any tests conducted by expert witnesses correspond with the realities of the case with which they are concerned. (4) Magistrates should examine carefully whether the presumption that the machine is reliable is challenged by relevant evidence. Thus, for example, if (a) it is common ground that in the case of a particular defendant there would not have been mouth alcohol or alcohol vapour in the dead-space of the upper respiratory tract, (b) the reliability of the particular device is challenged by expert evidence confined to the effect on the instrument of mouth alcohol or alcohol vapour, (c) the Magistrates are satisfied that the device was otherwise reliable, (d) the presumption the machine is reliable will not have been challenged by relevant evidence. In the above example the challenge to the reliability of the particular device would not be relevant on the facts of the case. (5) Magistrates should remember that expert evidence relates only to part of the case and that whilst it may be of assistance in reaching a decision, they must reach a decision having considered all the evidence. If the presumption that the machine is reliable is challenged by relevant evidence, Magistrates will have to be satisfied that the machine provided a reading upon which they can rely before making the assumption that the proportion of alcohol in the specimen was not less than the proportion of alcohol at the time of the offence. Magistrates must consider all the evidence bearing in mind, where applicable, Lord Goff's observations set out in para 44 above. If after considering all the evidence (the burden of proof being on the prosecution) they are sure that the defendant is guilty, they must find the defendant guilty. If they are not sure, they must find the defendant not guilty."
"(3) Were we wrong to allow the respondent to adduce rebuttal evidence during the appellant's case? (4) Did we err in law in allowing the Service Engineer's report undersection 27 Criminal Justice Act 1988 to be admitted in evidence? (5) Did we err in law in allowing the Service Engineer's report to be given in evidence under the provisions ofsection 24 Criminal Justice Act 1988 ?"
"If, having regard to all the circumstances -- (a) the Crown court ... or (c) a Magistrates' Court on a trial of an information is of the opinion that in the interests of justice a statement which is admissible by virtue of section 23 or 24 above nevertheless ought to be admitted, it may direct that the statement shall be not be admitted. (2) Without prejudice to the generality of subsection (1) above, it shall be the duty of the court to have regard -- (a) to the nature and source of the document containing the statement and to whether or not, having regard to its nature and source and to any other circumstances that appear to the court to be relevant it is likely that the document is authentic; (b) to the extent to which the statement appears to supply evidence which would otherwise not be readily available; (c) to the relevance of the evidence that it appears to supply to any issue which is likely to have to be determined in the proceedings; and (d) to any risk, having regard in particular to whether it is likely to be possible to controvert the statement if the person making it does not attend to give oral evidence in the proceedings, that its admission or exclusion will result in unfairness to the accused or, if there is more than one, to any of them."
"As a rule, these rights require that an accused should be given an adequate and proper opportunity to challenge and question a witness, either at the time the witness was making his statement or at some later stage of the proceedings."
"Could a reasonable Bench properly directing themselves on the law have, on the admissible evidence, convicted the appellant?"
"Although costs were reasonably incurred, was it proportionate to award costs of£2,500 to the respondent when the fine was£1,500 ?"
"Was the hearsay evidence of Dr Mundy about each machine being tested every six months and after the Andover case admissible as an exception to the rule against hearsay?"
"If we were right to refuse the admission of the letters by Mr Rudrum and Mr Cunliffe because they did not relate to the Ealing machine, were we right to allow Dr Mundy and Professor Makin to give evidence about other Intoximeters?"
