Parties to Crime in UK Law

Conspiracy, when regarded as a crime, is the agreement of two or more persons to effect any unlawful purpose, whether as their ultimate aim, or only as a means to it, and the crime is complete if there is such agreement, even though nothing is done in pursuance of it. But the tort of conspiracy is constituted only if the agreed combination is carried into effect in a greater or less degree and damage to the Plaintiff is thereby produced.

It is enough to say that if there is more than one purpose actuating a combination, liability must depend on ascertaining the predominant purpose. If that predominant purpose is to damage another person and damage results, that is tortious conspiracy. If the predominant purpose is the lawful protection or promotion of any lawful interest of the combiners (no illegal means being employed), it is not a tortious conspiracy, even though it causes damage to another person.

The rationale of the confiscation regime is that the defendant is deprived of what he has gained or its equivalent. He cannot, and should not, be deprived of what he has never obtained or its equivalent, because that is a fine. This must ordinarily mean that he has obtained property so as to own it, whether alone or jointly, which will ordinarily connote a power of disposition or control, as where a person directs a payment or conveyance of property to someone else.

contemplates that the defendant in question should have been instrumental in getting the property out of the crime. Not necessarily the only cause: there may, plainly, be other actors playing their parts. All that is required is that the defendant's acts should have contributed, to a non-trivial (that is, not de minimis) extent, to the getting of the property. This is no more than an instance of the common law's conventional approach to questions of causation.

While we in no way wish to detract from the obligation upon a Judge to advise a jury to proceed with caution where there is material to suggest that a witness's evidence may be tainted by an improper motive, and the strength of that advice must vary according to the facts of the case, we cannot accept that there is any obligation to give the accomplice warning with all that entails, when it is common ground that there is no basis for suggesting that the witness is a participant or in any way involved in the crime the subject matter of the trial.
