“(1) Where a person tried on indictment has been acquitted (whether in respect of the whole or part of the indictment) the Attorney General may, if he desires the opinion of the Court of Appeal on a point of law which has arisen in the case, refer that point to the court, and the court shall, in accordance with this section, consider the point and give their opinion on it. (2) For the purpose of their consideration of a point referred to them under this section the Court of Appeal shall hear argument— (a) by, or by counsel on behalf of, the Attorney General; and (b) if the acquitted person desires to present any argument to the court, by counsel on his behalf or, with the leave of the court, by the acquitted person himself... (7) A reference under this section shall not affect the trial in relation to which the reference is made or any acquittal in that trial.”
“89…civil disobedience on conscientious grounds has a long and honourable history in this country. People who break the law to affirm their belief in the injustice of a law or government action are sometimes vindicated by history. The suffragettes are an example which comes immediately to mind. It is the mark of a civilised community that it can accommodate protests and demonstrations of this kind. But there are conventions which are generally accepted by the law-breakers on one side and the law-enforcers on the other. The protesters behave with a sense of proportion and do not cause excessive damage or inconvenience. And they vouch the sincerity of their beliefs by accepting the penalties imposed by the law. The police and prosecutors, on the other hand, behave with restraint and the magistrates impose sentences which take the conscientious motives of the protesters into account… 90. These appeals and similar cases concerned with controversial activities such as animal experiments, fox hunting, genetically modified crops, nuclear weapons and the like, suggest the emergence of a new phenomenon, namely litigation as the continuation of protest by other means… The protesters claim that their honestly held opinion of the legality or dangerous character of the activities in question justifies trespass, causing damage to property or the use of force. By this means they invite the court to adjudicate upon the merits of their opinions and provide themselves with a platform from which to address the media on the subject. ... 93. My Lords, I do not think that it would be inconsistent with our traditional respect for conscientious civil disobedience for your Lordships to say that there will seldom if ever be any arguable legal basis upon which these forensic tactics can be deployed. 94. The practical implications of what I have been saying for the conduct of the trials of direct action protesters are clear. If there is an issue as to whether the defendants were justified in doing acts which would otherwise be criminal, the burden is upon the prosecution to negative that defence. But the issue must first be raised by facts proved or admitted, either by the prosecution or the defence, on which a jury could find that the acts were justified… Evidence to support the opinions of the protesters as to the legality of the acts in question is irrelevant and inadmissible, disclosure going to this issue should not be ordered ...”
“When considering whether an issue should not be left to the jury, we have well in mind two principles. First, the judge may not direct a jury to convict. But that prohibition is to be distinguished from circumstances in which a judge is entitled to withdraw an issue from the jury, or where an issue does not arise on the evidence and so no direction need be given about it to the jury (R v. Wang[2005] 1 WLR 661 at [3] and [8] to [14]). Secondly, a judge may withdraw an issue from the jury if no reasonable jury properly directed could reach a particular conclusion (e.g. that the defendant might have acted under duress (R v. Bianco[2001] EWCA Crim 2516 at [15]); that the defendant might have a “reasonable excuse” (R v. Nicholson[2006] 1 WLR 2857 at [9]; R v. G[2010] 1 AC 43 , 87D); or loss of self-control (R v. Martin[2017] EWCA Crim 1359 at [39]).”
“[t]he fact that a defence might be considered hopeless on the merits is not a good reason for a judge to withdraw it from the jury”
“The court can only rule that the explanation advanced by a defendant is incapable in law of amounting to a good reason or a reasonable excuse if it can properly be said, on the true construction of the Act, that it would be inconsistent with the essential nature and purpose of the offence for the defendant’s explanation to be capable of amounting to a defence. R v Kelleher 147 SJLB 1395 is a good example…”
