'In the case of each child, without necessarily having to determine the precise cause or causes of their death and for which no natural or known cause was said to be apparent at the time, you must be sure that the act or acts of the defendant, whatever they were, caused the child's death in that it was more than a minimal cause”.
What does this mean , “and for which no natural or known cause was said to be apparent at the time…?” All the deaths had a natural cause listed on the death certificates, so I don’t understand how this works in terms of what the jury has to decide.
This comes down to causation, the key word being "no natural or known cause". It's a long time since I took my criminal law exams but I've just done a very quick refresher (online google!) and two aspects of causation need to be shown for criminal liability to be established- factual and legal. Factual can be shown by the "but for" test, i.e. but for the defendant's actions the baby wouldn't have died (so no other cause for the death). For legal causation to be proven, it needs to be established the defendant's actions were more than minimal ( plus a few other things - law is never straightforward!). So this is the judge simplifying the law for the jury.
Off topic but just got a flashback to my criminal law exams - we had mad scenarios where someone would be beaten up, then someone else would stab them, then they would be taken to hospital and given the wrong medicine, and finally the cleaner would pull the plug out of their ventilator to plug in the hoover and the person would die. We would have to then go through all the perpetrators and determine what they could be charged with. I found it really interesting!
ETA I see what you mean about the phrasing of "apparent at the time". It does read strangely.
