Director of Public Prosecutions -v- Wilson [2017] IESC 54 (19 July 2017)

The Supreme Court held that the collection and analysis of DNA from cigarette butts discarded by Mr. Wilson while in custody did not breach his constitutional rights, as the items were lawfully obtained and no deception was used. The statutory regime permitted the taking of bodily samples, and the Gardaí were not required to use force where alternative lawful means existed. DNA evidence, when supported by extremely remote statistical probability of a random match and properly connected to the crime, can be sufficient to establish guilt beyond reasonable doubt. There is no legal requirement for a mandatory warning to the jury when conviction is based solely on DNA evidence.

Ratio Decidendi

The Supreme Court held that the collection and analysis of DNA from cigarette butts discarded by Mr. Wilson while in custody did not breach his constitutional rights, as the items were lawfully obtained and no deception was used. The statutory regime permitted the taking of bodily samples, and the Gardaí were not required to use force where alternative lawful means existed. DNA evidence, when supported by extremely remote statistical probability of a random match and properly connected to the crime, can be sufficient to establish guilt beyond reasonable doubt. There is no legal requirement for a mandatory warning to the jury when conviction is based solely on DNA evidence.
