"At about 11.50 pm on17th January 2003 [Mr Beckett] was observed driving [his] Ford Escort by Police Constable David Johnson and Acting Police Sergeant Neil Jones (who were in uniform) as he drove into Coffee Hall, a residential area in Milton Keynes. He was signalled to stop, and did so after continuing to drive for a short distance. Constable Johnson spoke on the Appellant and asked him if it was his vehicle. When the Appellant replied, Constable Johnson immediately noticed the smell of intoxicating liquor on his breath. He Constable asked the Appellant if he had been drinking and the Appellant said he had had, 'a couple of pints'. Suspecting that the appellant had been driving with alcohol in his body, Constable Johnson required the Appellant to take a breath test, which was positive, whereupon the Appellant was arrested and taken to Milton Keynes police station. At the police station the evidential breath procedure was carried out and the Appellant, who was compliant, provided two specimens of breath upon an approved device. The lower reading given by the device for the proportion of alcohol in his breath was 58 micrograms of alcohol per 100 millilitres of breath -- a figure in excess of the statutory maximum of 35 microgrammes per 100 millilitres."
"Constable Johnson said that he had stopped the Appellant in the exercise of his power undersection 163 of the Road Traffic Act 1988 to check his documentation. It was a random check. When asked in cross-examination to expand upon this, he said that factors that had caused him to stop the Appellant had been the lateness of the hour, the fact that the car contained a single occupant and that the car was 'an older vehicle'. He had noticed alcohol on the Appellant's breath before he had got round to asking for his documents. He and the Appellant had been standing face to face in the initial conversation. The evidence of Acting Sergeant Jones was that it was a random stop to check documents and the road worthiness of the car. He had not spoken to the appellant in the first instance and had been a few yards away looking at the vehicle during the initial conversation, and had not overheard what had been said. The Appellant's evidence was that he had been about eight feet from Constable Johnson during the initial conversation. However, he agreed that he had told the officer that he had had, 'a couple of pints', and that the second officer had been looking at his car. He complained that he had been stopped upon the pretext of checking documents so that the police officers could 'avoid the random breath test law'."
"It was, in effect, contended by the Appellant (who was not legally represented) that as he had been stopped upon a random basis without any cause; that random stopping of motorists is prohibited by law; the officers should not have administered the breath test and the court should not have regard to the evidence of the subsequent breath testing upon the evidential device. Save that he asserted that it was a random stop a fact that was not in dispute) the Appellant did not allege bad faith on the part of the police officers."
"(a) It is well settled law that a police officer in uniform is entitled, by virtue ofsection 163 of the Road Traffic Act 1988 , to stop any person driving a motor vehicle on a road. He does not require grounds to do so, providing that he is acting in good faith. The constable's duty and power come from the section itself. (See Beard v Wood [1980] RTR 454). (b) It is, similarly, well settled law that in the absence of malpractice, oppression, caprice or opprobrious behaviour, there is no restriction on the stopping of motorists by a police officer in the execution of his duty and subsequent requirement of a breath test if the officer then and there genuinely suspects the ingestion of alcohol. (See Chief Constable of Gwent v Dash [1986] RTR 41, a case in which the only purpose of the stop was to ascertain whether the driver had alcohol in his body). (c) There was no evidence that Constable Johnson and Acting Sergeant Jones were acting otherwise than in good faith when they decided to stop the Appellant. The reasons given by them for doing so appeared to us to be adequate reasons. The Appellant adduced no significant evidence or argument to suggest otherwise. (In his application to this court to state a case, the appellant asserts the existence of a discrepancy between the evidence of the officers and the custody record. However, no evidence was adduced before us upon the hearing of the appeal as to the contents of the custody record and we were not aware of its contents). (d) In those circumstances we concluded that there was no basis upon which we should regard the evidence of the proportion of alcohol in the Appellant's breath as inadmissible or disregard that evidence. (e) There being no issue as to the remaining elements of the offence, we dismissed the appeal, upheld the conviction and ordered the Appellant to pay the sum of£250 in respect of the Respondent's costs of the appeal, to be paid within 28 days. (f) Upon the hearing of the appeal, the Appellant did not claim to rely upon theHuman Rights Act 1998 . Had he done so, we have taken the view that the restriction upon liberty authorised by section 163 is insufficient to offendArticle 5 of the Convention ."
"On the other hand, it appears to me that there is an arguable point of law which Mr Beckett could take further if he is willing to bear the risks of the costs involved. On the face of it, the police do have power to stop people under the Act, but Mr Beckett's challenge at his appeal was that this was not the random stop of police officers who were in the habit of stopping people at all times of the day and night to check their documents. This was a misuse of police power, when they were thwarted by the rule that they are not entitled to stop drivers at random to check the alcohol on their breath, and that, accordingly, he should not lawfully have been stopped. In those circumstances, the events which led up to his conviction should not be relied on."
"A person driving a mechanically propelled vehicle on a road must stop the vehicle on being required to do so by a constable in uniform."
"The word 'malpractice', as it has come to be used in this field, seems to me to cover cases where the police have acted from some indirect or improper motive or where the conduct on the part of the police could be described as capricious. The random stopping of cars undersection 159 of the Road Traffic Act 1972 for the purpose of detecting crime, or for inquiring whether the driver has had too much to drink, cannot be so described. Nor can it be said that the police were acting from some indirect or improper motive. However much the public may dislike the random stopping of cars, I cannot agree that random stopping by itself involves malpractice, and if Donaldson LJ said otherwise in Such v Ball to which Macpherson J has referred, then, I would very respectfully disagree."
"in summary, therefore, the police are, in my judgment, not prohibited from the random stopping of cars within the limits already referred to; but are, of course, prohibited from requiring breath tests at random, which is a very different thing. That distinction must always be borne in mind."
"... nothing insection 159 of the Road Traffic Act 1972 required the prosecutor to prove that a constable in uniform acting in the execution of his duty under that section was acting under some common law power for he derived his duty and his powers from the terms of section 159 itself; that since the facts established that the defendant, when driving a vehicle on a road, was required to stop by a uniformed constable not acting capriciously, the defendant, seemingly, had no answer to the charge."
"It should, however, be stated that the police officer was acting within the execution of his duty by virtue of his power at common law and not by virtue of any power contained in section 159 of the Road Traffic Act [which he quoted]."
"The finding that the police officer was acting lawfully in the execution of his duty at the time he stopped the defendant is sufficient to dispose of the appeal."
