"Because I am the judge of the law, ladies and gentlemen, any legal directions I give you, you must comply with. But I am not a judge of the facts and only you are the judges of the facts. So, as you are the judges of the facts, how do you act as a judge? ... [Y]ou act as you would wish and expect a judge to act, fairly, calmly, without prejudice and solely on the evidence. Each of you has sworn or affirmed to give a true verdict according to the evidence. The evidence is what you hear in the four walls of this courtroom from the witnesses who will give their evidence in the witness box and the exhibits which attended as part of the evidence. [T]hat is what you judge the case on and that alone. The evidence from the witnesses here in court in front of you and the exhibits tendered as part of the evidence. During the trial, witnesses are called to give evidence and they will be questioned and tested by questions, that's the proper process of the court, ladies and gentlemen. You see that happening and you judge the case on the evidence led here in front of you in court ...
A very important thing follows from that and it's this: you must not decide the case on anything outside the court ...
The next thing is this, and this is very important in this case as in every case. Do not go and do your own homework or do your own research, don't go and look up old newspapers, don't go down to the local library, do not go and look at the internet, do not do any electronic searches about anyone connected with this case, that's very important ladies and gentlemen. You have sworn or affirmed to give a true verdict on the evidence led here in court, therefore looking at anything else cannot help you because that's not the evidence ...
Your function is to decide the case solely [on] the evidence and I will give you various directions during the case to assist you in that regard but they are the first ones that I give you so that you know the limitations of what you should be looking at, just the evidence here in court and nothing else."
