8 O’HALLORAN AND FRANCIS v. THE UNITED KINGDOM JUDGMENT defendant’s appeal, finding that the prosecution could not rely on evidence of the admission which she had been compelled to make. 31. On appeal by the Procurator Fiscal, the Privy Council found that the use of the admission did not infringe the requirements of Article 6 of the Convention. Lord Bingham of Cornhill, giving the leading judgment, held, inter alia: “The high incidence of death and injury on the roads caused by the misuse of motor vehicles is a very serious problem common to almost all developed societies. The need to address it in an effective way, for the benefit of the public, cannot be doubted. Among other ways in which democratic societies have sought to address it is by subjecting the use of motor vehicles to a regime of regulation and making provision for enforcement by identifying, prosecuting and punishing offending drivers. Materials ... incomplete though they are, reveal different responses to the problem of enforcement. Under some legal systems (Spain, Belgium and France are examples) the registered owner is presumed to be the driver guilty of minor traffic infractions unless he shows that some other person was driving at the relevant time or establishes some other ground of exoneration. There being a clear public interest in enforcement of road traffic legislation the crucial question in this case is whether section 172 represents a disproportionate response, or one that undermines a defendant’s right to a fair trial, if an admission of being the driver is relied on at trial. I do not for my part consider that section 172, properly applied, does represent a disproportionate response to this serious social problem, nor do I think that reliance on the respondent’s admission in the present case, would undermine her right to a fair trial. I reach that conclusion for a number of reasons. 1. Section 172 provides for the putting of a single, simple question. The answer cannot of itself incriminate the suspect, since it is not without more an offence to drive a car. An admission of driving may, of course, as here, provide proof of a fact necessary to convict, but the section does not sanction prolonged questioning about facts alleged to give rise to criminal offences such as understandably was held to be objectionable in Saunders, and the penalty for declining to answer under the section is moderate and non-custodial. There is in the present case no suggestion of improper coercion or oppression such as might give rise to unreliable admissions and so contribute to a miscarriage of justice, and if there were evidence of such conduct the trial judge would have ample power to exclude evidence of the admission. 2. While the High Court was entitled to distinguish ... between the giving of an answer under section 172 and the provision of physical samples, and had the authority of the European Court in Saunders ... for doing so, this distinction should not in my opinion be pushed too far. It is true that the respondent’s answer whether given orally or in writing would create new evidence which did not exist until she spoke or wrote. In contrast, it may be acknowledged, the percentage of alcohol in her blood was a fact, existing before she blew into the breathalyser machine. But the whole purpose of requiring her to blow into the machine (on pain of a criminal penalty if she refused) was to obtain evidence not available until she did so and the reading so obtained could, in all save exceptional circumstances, be enough to convict a driver of an offence ... [I]t is not easy to see why a requirement to answer a question is objectionable and a requirement to undergo a breath test is not. Yet no criticism is made of the requirement that the respondent undergo a breath test.
