"A constable must, on requiring any person to provide a specimen in pursuance of this section, warn him that a failure to provide it may render him liable to prosecution."
"(1) Subject to subsection (2) below, of any two specimens of breath provided by any person in pursuance of section 7 of this Act that with the lower proportion of alcohol in the breath shall be used and the other shall be disregarded. "(2) If the specimen with the lower proportion of alcohol contains no more than 50 microgrammes of alcohol in 100 millilitres of breath, the person who provided it may claim that it should be replaced by such specimen as may be required under section 7(4) of this Act and, if he then provides such a specimen, neither specimen of breath shall be used."
"4(b) At the said station, the appellant was lawfully required to provide 2 specimens of breath for analysis, which he did. "(c) The officer requiring those specimens reasonably believed that the device used was of a type approved by the Secretary of State. "(d) The lower of the two analyses indicated a proportion of alcohol in the appellant's breath that did not exceed 50 microgrammes of alcohol in 100 millilitres of breath. "(e) The appellant exercised his option undersection 8(2) of the Road Traffic Act 1988 and provided a specimen of blood. "(f) The alcohol level in the aforementioned specimen of blood exceeded the prescribed limit."
"7) We were of the opinion that -- "(a) The references tosection 7 of the Road Traffic Act 1988 in section 8 of that Act would not exclude the operation of the latter section in a case in which, unknown to the operating officer, modifications had been made to the breath testing device to an extent that meant that the device fell outside the scope of the approval of the Secretary of State. "(b) The appellant had not been required to give a sample of blood but had claimed the right to do so provided for bysection 8(2) of the Road Traffic Act 1988 . He having claimed that right and provided a sample of breath in pursuance thereof, we were required to disregard the evidence of the proportion of alcohol in the appellant's breath provided by the breath-testing device. "(c) The procedure adopted gave rise to no unfairness to the appellant, who had not sought to adduce any evidence to suggest that the amount of alcohol in his metabolism had not exceeded the prescribed limit. "(d) We, therefore, agreed with the first submission made for the respondent that approval of the breath-testing device was irrelevant and ruled that evidence intended to show that, by reason of modification, the device in question had ceased to be of an approved type would be inadmissible."
"Were we correct in refusing to allow the appellant to adduce evidence intended to show that the breath testing device used in this case was not an approved device?"
"Assuming that the machine is working properly, clearly it is appropriate in a borderline case to give the defendant the opportunity to provide instead a specimen of blood. After all, if he does not provide it he will fall to be convicted on his breath specimen. Assume, however, that the machine is not working properly, then in any event it is open to the police officer to require the blood specimen. I can see no possible reason why the prosecution should have to prove one way or the other whether the machine was actually working properly. The defendant is, if anything, better off if it is assumed to be working: the option then becomes his."
"The plain fact is that the questions formulated raise but a single issue, that which I earlier identified: does the prosecution have to prove that the machine was actually working accurately when a driver is put to his election under section 8(2)? In my judgment, the plain answer to that is 'No' and in the result this appeal falls to be dismissed."
"It is, therefore, in our judgment, not surprising that a strict and compulsory code is laid down as a set of pre-conditions which must be fulfilled before any specimen produced by the defendant, which may condemn him at the hearing of the charge against him, can be adduced in evidence: no matter that there may be some instances where breach of the code occasions no discernible prejudice."
"MR VOLLENWEIDER: Your Lordships, in the circumstances can I ask for costs? "
"MR VOLLENWEIDER: My Lord, it is sometimes difficult for counsel to give an estimate of -- "
"The failure by a party, without reasonable excuse, to comply with the foregoing paragraphs will be taken into account by the court in deciding what order to make about the costs of the claim, hearing or application, and about the costs of any further hearing or detailed assessment hearing that may be necessary as a result of that failure."
"Where he is requested to do so by the judge, the solicitor for the funded defendant shall provide an estimate of the total costs which are likely to be incurred under the representation order."
