"Does a person commit an offence undersection 1 of the Criminal Attempts Act 1981 where, if the facts were as that person believed them to be, the full offence would have been committed by him, but where on the true facts the offence which that person set out to commit was in law impossible, e.g., because the substance imported and believed to be heroin was not heroin but a harmless substance?"
"The prosecution must prove that the defendants did what they did knowingly. That is to say, it must be proved that they knew the goods were prohibited goods and had been imported into the United Kingdom, although, in the context of this case, they need not know precisely what the prohibited goods were, as long as they knew they were prohibited.
"The court is not prepared to accept that submission. It seems perfectly clear that the word "knowingly" in section 304( b ) is concerned with knowing that a fraudulent evasion of a prohibition in respect of goods is taking place. If, therefore, the accused knows that what is on foot is the evasion of a prohibition against importation and he knowingly takes part in that operation, it is sufficient to justify his conviction, even if he does not know precisely what kind of goods are being imported. It is, of course, essential that he should know that the goods which are being imported are goods subject to a prohibition. It is essential he should know that the operation with which he is concerning himself is an operation designed to evade that prohibition and evade it fraudulently. But it is not necessary that he should know the precise category of the goods the importation of which has been prohibited."
"Where in any proceedings for an offence to which this section applies [which includes an offence under section 5(2)] it is necessary, if the accused is to be convicted of the offence charged, for the prosecution to prove that some substance or product involved in the alleged offence was the controlled drug which the prosecution alleges it to have been, and it is proved that the substance or product in question was that controlled drug, the accused -
"(1) If, with intent to commit an offence to which this section applies, a person does an act which is more than merely preparatory to the commission of the offence, he is guilty of attempting to commit the offence.
"My Lords, it has been strenuously and ably argued for the respondent that these provisions involve that a defendant is liable to conviction for an attempt even where his actions are innocent but he erroneously believes facts which, if true, would make those actions criminal, and further, that he is liable to such conviction whether or not in the event his intended course of action is completed."
"Objectively considered, therefore, her purchase of the recorder was a perfectly proper commercial transaction."
"The question may be stated in abstract terms as follows. Does section 1 of the Act of 1981 create a new offence of attempt where a person embarks on and completes a course of conduct which is objectively innocent, solely on the ground that the person mistakenly believes facts which, if true, would make that course of conduct a complete crime? If the question must be answered affirmatively it requires
"Putting the hand in the pocket is the guilty act, the intent to steal is the guilty mind, the offence is appropriately dealt with as an attempt, and the impossibility of committing the full offence for want of anything in the pocket to steal is declared by [subsection (2)] to be no obstacle to conviction."
"If it is right in principle that an attempt should be chargeable even though the crime which it is sought to commit could not possibly be committed, we do not think that we should be deterred by the consideration that such a change in our law would also cover some extreme and exceptional cases in which a prosecution would be theoretically possible. An example would be where a person is offered goods at such a low price that he believes that they are stolen, when in fact they are not; if he actually purchases them, upon the principles which we have discussed he would be liable for an attempt to handle stolen goods. Another case which has been much debated is that raised in argument by Bramwell B. in Reg. v. Collins (1864) 9 Cox C.C. 497. If A takes his own umbrella, mistaking it for one belonging to B and intending to steal B's umbrella, is he guilty of attempted theft? Again, on the principles which we have discussed he would in theory be guilty, but in neither case would it be realistic to suppose that a complaint would be made or that a prosecution would
