The learned judge who presided at the trial (Maguire J.) early in his charge to the jury emphasized the intention of the accused as the thing they might find to be the crucial matter. His Honour directed them that the onus rested on the prosecution to satisfy them beyond reasonable doubt of the guilt of the accused and, after an explanation of that requirement, turned to the place taken in the case by the accused's story of matrimonial discord and unhappiness and his emotionally disturbed condition. In effect the learned judge said that, if the accused intended to kill the child, emotional or mental disturbance would afford no defence unless it amounted to insanity, a defence which was not set up. Subject to what he was about to say the jury could therefore discard from their minds any question of mental instability or lack of understanding or of normal mentality. His Honour then dealt with the reservation to which his statement was subject and explained that in both counts a specific intent was necessary, in the first a specific intent to murder, and, in substance, that the jury might think the accused's mental processes were such that they would not be prepared to say he had the intent which they might attribute to an ordinary man doing the same thing. His Honour then told the jury that on the first count the Crown must prove first that poison was administered to the child, secondly that it was administered by the accused and thirdly, what they might think in this case most important, that at the time he administered the poison he intended to murder her. He dealt with these issues in order and discussed the evidence relating to them. Under the first head, the learned judge defined poison as being a substance which if taken in sufficient quantity would be deleterious and harmful to human life or human health and well-being. It was not necessary for the Crown to prove that the dose administered was sufficient to bring about death; it was enough if the substance was of a nature to do so if administered in sufficient quantity, provided that the other two elements were proved. He spoke of the statement attributed to the accused that morphia had been administered and of the accused's case that he had given the child chloral hydrate. His Honour also mentioned sodium pentothal. He said that if they accepted the view that it was chloral hydrate and not morphia, it would not matter very much because both substances were poisons; if they were satisfied beyond reasonable doubt that any one of the substances was administered to the child the Crown would have established the first ingredient in the crime. The learned judge then turned to the question whether the poison so found to be administered was administered by the accused and dealt with some of the facts, ending that topic by saying that the accused said that he gave the child chloral syrup, that is chloral hydrate, but without the intention of committing a crime. His Honour then directed them with some fulness upon the issue whether the accused, if he administered poison, did so with intent to murder his child. He dealt first with the accused's case as to his intent and in doing so stated as part of his case that the accused put it that he was so worried and upset that he was not thinking clearly and did not measure out the child's dose with the care he otherwise might. His Honour then put the case for the Crown on the issue and in the course of stating it referred to the statements attributed by the detective sergeant and his fellow officer to the accused. He put before the jury the two questions which they must consider concerning the statements, namely first whether the accused said what was ascribed to him and second, if so, whether it could be relied upon as a true recital of what had happened. As his Honour made this point he referred to the assertion of the accused that at that time, viz. on the morning of 14th December, he was in a very confused and muddled state. As to the statement said to have been made by the accused on 21st December his Honour told the jury that the accused denied making any statement and he discussed the probabilities, having regard to the advice the accused had received from his solicitor. As his Honour drew to the conclusion of his charge he repeated that it was not necessary that the Crown should prove that a lethal dose of any particular poison was administered; it was sufficient if it was established that any quantity of poison was administered provided that it was established that at the time it was administered the accused intended to take the child's life. After making some further observations bearing upon the identification of the poison, his Honour said that there was plenty of poison about but just what happened or how it was used was a matter for them, remembering that it was not for the accused to prove his innocence. The charge ended with a brief reference to the case made by the accused.
