"In the rare cases in which it is necessary to direct a jury by reference to foresight of consequences, I do not believe it is necessary for the judge to do more than invite the jury to consider two questions. First, was death or really serious injury in a murder case (or whatever relevant consequence must be proved to have been intended in any other case) a natural consequence of the defendant's voluntary act? Secondly, did the defendant foresee that consequence as being a natural consequence of his act? The jury should then be told that if they answer yes to both questions it is a proper inference for them to draw that he intended that consequence."
" Do the questions to be considered by a jury set out in the speech of Lord Bridge of Harwich in Reg, v. Moloney [1985] A.C. 905, 929 as a model direction require amplification?"
"If the prosecution has made you satisfied so as to be sure that Dean Hancock and Russell Shankland agreed that they would, in concert, push or throw missiles from the bridge, each having the intention either to kill or to cause really serious injury, then you will find each of them guilty of murder as the block was thrown or pushed by Dean Hancock in pursuance of the agreement.
"You may think that critical to the resolution of this case is the question of intent. In determining whether a person intended to kill or to cause really serious injury, you must have regard to all of the evidence which has been put before you, and draw from it such inferences as to you seem proper and appropriate. You may or may not, for the purpose of considering what inferences to draw, find it helpful to ask: Was death or serious injury a natural consequence of what was done? Did a defendant foresee that consequence as a natural consequence? That is a possible question which you may care to ask yourselves. If you find yourselves not satisfied so as to be sure that there was an intent to kill or to cause really serious injury, then it is open to you to return a verdict of not guilty of murder, but guilty of manslaughter."
"Your Lordship,
"I conclude with the pious hope that your Lordships will not again have to decide that foresight and foreseeability are not the same thing as intention although either may give rise to an irresistible inference of such, and that matters which are essentially to be treated as matters of inference for a jury as to a subjective state of mind will not once again be erected into a legal presumption. They should remain, what they always should have been, part of the law of evidence and inference to be left to the jury after a proper direction as to their weight, and not part of the substantive law."
"But looking on their facts at the decided cases where a crime of specific intent was under consideration, including Reg, v. Hyam[1975] AC 55 itself, they suggest to me that the probability of the consequence taken to have been foreseen must be little short of overwhelming before it will suffice to establish the necessary intent."
"foresight of consequences, as an element bearing on the issue of intention in murder, or indeed any other crime of specific intent, belongs, not to the substantive law, but to the law of evidence."
