DPP v Peter Cullen, [2014 IESC 7]; [2014] 3 IR 30, was an Irish Supreme Court case in which the Court addressed the routine practice of An Garda Síochána of placing handcuffs after an arrest for drink driving. The court ruled that an arrest will be thrown out if it is shown that it was unnecessary to place handcuffs on the accused. There are certain circumstances that must be considered. For instance, whether the accused has a tendency for violence whilst intoxicated. The ruling raised the possibility that an invalidation of the arrest will also have an effect on the admissibility of the evidence.
