"It is in my judgment plain that the essence of what is meant by 'benefit' in section 71(4) is given by the verb 'obtain'; and whether in any given case a person has obtained any particular property must involve issues of fact."
"What remains to be said about the meaning of the word 'obtain' in section 71(4)? Clearly it does not mean 'retain' or 'keep'. But no less clearly, in my judgment, it contemplates that the defendant in question should have been instrumental in getting the property out of the crime. His acts must have been a cause of that being done. 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."
