Which case highlighted jury misconduct involving a juror's social media activity?

The case that highlighted jury misconduct involving a juror's social media activity is R v Skaf. This case is significant because it involved a juror who engaged with social media during the trial, which raised concerns about the integrity of the jury process and the potential impact of external information on jury deliberations. The juror’s actions attracted attention to the risks associated with social media use and how it could influence the impartiality of jurors. Such misconduct undermines the fairness of the trial and the legal principle that jurors must decide cases based solely on the evidence presented in court.

Other cases mentioned, while important in their own rights, do not specifically address the issue of social media misconduct in relation to juror behavior.
