"The device known as the Intoximeter EC/IR, manufactured by Intoximeters Inc, of St Louis Missouri, composed of the Intoximeter EC/IR, the Intoximeter EC/IR Gas Delivery System and software version EC/IR-UK5.23."
"A preliminary point was taken on behalf of the Appellant that the proceedings should be further adjourned as the prosecution had failed to provide full disclosure the service history of the Intoximeter device. It was contended on his behalf that modifications to the Intoximeter device had been such that it was no longer in the same condition as it had been when the Secretary of State's approval was given, and the Appellant's defence would be handicapped if fuller information were not available. We refused this application for reasons which are given in paragraph 7 (below)."
"We were of the opinion that (a) We should refuse the request for an adjournment as the issue of approval of a device was a matter solely for the Secretary of State, and no useful purpose would be served by the disclosure of information calculated to suggest that the device should not continue to enjoy that approval."
"(a) Were we correct in ruling that the approval of the Intoximeter device could not be challenged in this court, and that the request for an adjournment should therefore be refused?"
"(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."
"If the provision of a specimen other than a specimen of breath may be required in pursuance of this section the question whether it is to be a specimen of blood or a specimen of urine shall be decided by the constable making the requirement, but if a medical practitioner is of the opinion that for medical reasons a specimen of blood cannot or should not be taken the specimen shall be a specimen of urine."
"Everyone charged with a criminal offence has the following minimum rights: ... (b) to have adequate time and facilities for the preparation of his defence."
"It is likely that there will in practice be a fine line between: (a) Requiring the police not to obstruct the preparation of a defence, which must be implied in the right recognised in section 24(d) [which is the relevant provision of the Bill Of Rights Act]; and (b) Imposing on the police a new and affirmative duty to assist in the collection of evidence useful for the defence. "
"Failure may or may not amount to a breach of the right given by section 24(d).
