"I reject the proposition, if that is what is suggested, that the prosecution at this stage must exclude all reasonable possibilities consistent with innocence; that is a decision ultimately for a jury to make. The question is whether there is evidence, in the case of any particular defendant, on which a jury, properly directed, could infer guilt. In deciding whether there is a case for any particular defendant to answer, it is not my function to decide whether I can reject all reasonable possibilities consistent with innocence; rather, the question is whether a reasonable jury could, on one possible view of the evidence, conclude that a defendant was guilty. It is undoubtedly the case that any jury considering the case where they are invited to draw adverse inferences from a combination of factual circumstances will have to reject all realistic possibilities consistent with innocence which might be put before them before they can safely draw conclusions adverse to any of the defendants. That is not my task at this stage. There are sometimes cases where it may be necessary for a judge to consider other reasonable probabilities and, occasionally, the outcome might be a ruling that there is no case to answer. These tend to be factually very simple cases: R v Younis Masih[2015] EWCA Crim 477 is one example of such a case. However, every case is fact specific."
"As we have explained, secondary liability does not require the existence of an agreement between D1 and D2. Where, however, it exists, such agreement is by its nature a form of encouragement and in most cases will also involve acts of assistance. The long established principle that where parties agree to carry out a criminal venture, each is liable for acts to which they have expressly or impliedly given their assent is an example of the intention to assist which is inherent in the making of the agreement. Similarly, where people come together without agreement, often spontaneously, to commit an offence together, the giving of intentional support by words or deeds, including by supportive presence, is sufficient to attract secondary liability on ordinary principles. We repeat that secondary liability includes cases of agreement between principal and secondary party, but it is not limited to them."
"The agreement alleged in this case is a conditional agreement: that 'should the need arise, one or more of them would use unlawful violence upon another or others, intending to cause that other person or persons really serious injury.' The defendants may have joined the agreement at different points in the course of the evening."
"Matters of assessment and weight of the evidence are for the jury and not for the judge. Since the judge is concerned with the sufficiency of evidence and not with the ultimate decision the question is not whether all juries or any particular jury or the judge would draw the inference of guilt from the evidence adduced but whether a reasonable jury could draw the inference of guilt."
"... it is possible for death to be caused by some overwhelming supervening act by the perpetrator which nobody in the defendant's shoes could have contemplated might happen and is of such a character as to relegate his acts to history; in that case the defendant will bear no criminal responsibility for the death."
