“I am a serving police officer. I know Mark Blackburn but I haven’t worked with him for over two years.”
“The Court is of the view that, leaving aside the question whether the presence of a police officer on a juror could ever be compatible with Article 6, where there is an important conflict regarding police evidence in the case and a police officer who is personally acquainted with the police officer witness giving the relevant evidence is a member of the jury, jury directions and judicial warnings are insufficient to guard against the risk that the juror may, albeit subconsciously, favour the evidence of the police. In the present case, [the juror] had known Mark Blackburn for ten years and although not from the same station, had on three occasions worked with him in the investigation of the same incident (…). Further, the other witnesses who supported Mark Blackburn’s account of events were also police officers (…). The Court recalls the conclusion of the Court of Appeal that the first applicant’s defence witness was not a witness of good character and that his explanation for the records of the use of his mobile phone and the discovery of heroin in his car “bordered on the farcical” (…). However, it is not for this Court to make its own assessment of the evidence presented at trial and, in particular, of the first applicant’s explanation for the evidence against him. Such assessment was for the members of the jury, who were required pursuant to Article 6 to be impartial.”
“The Court recalls the applicants were co-defendants in one set of criminal proceedings and that they were convicted by the same jury. In these circumstances, the Court considers that, having found in its examination of the first applicant’s complaint that the jury in the case could not be considered to constitute an “impartial tribunal” in light [the juror]’s presence, it would be artificial to reach a different conclusion regarding the “tribunal” which tried the second applicant. Thus, notwithstanding the fact that the jury was required to try the case against each applicant separately and was permitted to come to different verdicts in respect of each applicant, the Court considers that there has also been a violation of Article 6 § 1 in respect of the second applicant.”
“We are unable to envisage any circumstance in which, an Article 6 breach having arisen from want of independence and impartiality in the tribunal, it would be possible to conclude that the conviction is safe.”
“The third appellant was entitled to be tried by a tribunal that was and appeared to be impartial, and in my opinion he was not. The consequence is that his convictions must be quashed. This is a most unfortunate outcome, since the third appellant was accused of very grave crimes, of which he may have been guilty. But even a guilty defendant is entitled to be tried by an impartial tribunal and the consequence is inescapable.”
“9. It is important to distinguish between partiality towards the case of one of the parties and partiality towards a witness. Each can be describes as 'bias' but they are different in kind and can have different consequences. Association with or partiality towards a witness will not necessarily result in the appearance of bias, as defined by Lord Goff [in R v Gough]. Just because a juror feels partial to a particular witness does not mean that the juror will be partial to the case in support of which that witness is called. It may do so if the witness is so closely associated with the prosecution that partiality to the witness is equated with partiality towards the party calling the witness. Such a case was In re Medicaments[2001] 1 WLR 700 where an appearance of bias resulted from the fact that a member of the tribunal had applied for a job to the experts whose evidence was the foundation of the case of one of the parties. In many cases, however, the witness will not be associated with the prosecution in this way. 10. Where an impartial juror is shown to have had reason to favour a particular witness, this will not necessarily result in the quashing of a conviction. It will only do so if this has rendered the trial unfair, or given it an appearance of unfairness. To decide this it is necessary to consider two questions: i) Would the fair minded observer consider that partiality of the juror to the witness may have caused the jury to accept the evidence of that witness? If so ii) Would the fair minded observer consider that this may have affected the outcome of the trial? If the answer to both questions is in the affirmative, then the trial will not have the appearance of fairness. If the answer to the first or the second question is in the negative, then the partiality of the juror to the witness will not have affected the safety of the verdict and there will be no reason to consider the trial unfair. …. 29. Our conclusion is, as already expressed, that the fact that a police juror may seem likely to favour the evidence of a fellow police officer will not, automatically, lead to the appearance that he favours the prosecution. If the police evidence is not challenged or does not form an important part of the prosecution case, we do not consider that it will normally do so. None the less it will be appropriate to quash the conviction if, but only if, the effect of the juror's partiality towards a brother officer puts in doubt the safety of the conviction and thus renders the trial unfair.”
“Whether the fair-minded and informed observer, having considered the facts, would conclude that there was a real possibility that the tribunal was biased.”
“First of all, whether, if the police evidence is challenged, it forms an important part of the prosecution case, and secondly, any possibility of bias that might result from the closeness of the connection between the policeman on the jury and the police officer giving evidence.”
