The High Court ruled that Garret Byrne was lawfully detained at the roadside during searches of him, his car and his passenger, and that his later arrest under road traffic legislation was lawful.
Mr Justice Hedigan delivered the judgment on 31 July 2014 in a case stated by District Court Judge Anne Watkin. The High Court answered “yes” to both questions put to it: whether the roadside detention was permitted under section 23 of the Misuse of Drugs Act, and whether the subsequent arrest under section 4(8) of the Road Traffic Act 2010 was lawful. A third question, about whether evidence of a blood-or-urine requirement and an alleged failure to comply should be excluded if either earlier step was unlawful, did not arise.
The case arose from a charge alleging that Byrne refused to provide a blood specimen after a doctor required one at Raheny Garda Station on 15 November 2012. The charge followed two unsuccessful attempts to provide a urine sample. Byrne said he could not provide urine and was afraid of needles, according to the evidence summarized in the judgment. The High Court was not deciding whether he committed the charged offence.
At the District Court hearing, Garda Niall McDonnell testified that he smelled cannabis from Byrne’s car and suspected Byrne was under the influence of an intoxicant. Searches of Byrne, his passenger and the car were negative. A dog unit also searched the car. McDonnell estimated that the searches took about 15 minutes in total; Byrne was arrested after they were completed. The judgment records that Byrne did not attempt to leave the scene.
The defence argued that Byrne had been kept at the roadside without being told he was under arrest or that a statutory detention power applied. It said this made the later arrest unlawful. The prosecution argued that the searches formed part of one investigation and that the detention was lawful.
Justice Hedigan held that section 23 allowed Gardaí to detain a person for the reasonable time needed to search them, and to require a person in control of a vehicle to remain with it while it was searched. Given the short duration, the linked searches and the circumstances described in evidence, he found the detention lawful and the later arrest valid. The judgment records the District Court’s earlier ruling on the detention and arrest; the High Court’s answers addressed those legal questions in the case stated.
