R v Taaffe  AC 539
Drug importation – Requirement of actual knowledge of drugs
Paul Desmond Taafe (T) was enlisted by a third party in Holland to import cannabis into England, which was prohibited to import under the . T, however, had mistakenly believed the substance to be currency, which T had believed was prohibited to import but was in fact not. T was charged under section 170(2) of the Customs and Excise Management Act 1979 (1979 Act) of having been knowingly concerned in the fraudulent evasion of the prohibition on the importation of cannabis. T was convicted and appealed.
The issue in question was whether T’s version of events in which he had erroneously believed the prohibited substance to be currency, if accepted by the jury, should entitle him to be acquitted.
‘Knowingly concerned’ under section 170(2) of the 1979 Act had to be read as actual knowledge that the substance in question was one the importation of which is prohibited. T was not knowingly concerned in the fraudulent evasion of the prohibition on the importation of cannabis when he mistakenly believed that the substance he was importing was currency. For an offence of which the ingredients are the defendant’s state of mind and knowledge, the defendant must be judged on the facts as he believed them to be. T’s mens rea for the impossible offence of smuggling currency could not be imported to the smuggling of drugs. The Court of Appeal allowed T’s appeal and his conviction was quashed. The House of Lords dismissed the prosecution’s appeal.
