Criminal law – Appeal. The Court of Appeal, Criminal Division dismissed the defendants' appeal against conviction for conspiracy, together and with other persons, to be concerned in the production of a controlled drug, namely cannabis, by another in contravention of s 4(2)(b) of the Misuse of Drugs Act 1971. The defendants' role in the conspiracy had been to make and supply bespoke equipment for the purpose of supplying cannabis farms with the said equipment throughout the United Kingdom and Ireland, which were used to assist in the cannabis growing process. The defendants, amongst other things, denied that they could be involved in such a conspiracy due to their not knowing or caring what the equipment would be used for. That argument was rejected and the convictions were concluded as safe.
