In R v TR and others  EWCA Crim 1035 the Court of Appeal granted an application by the Crown to hold this trial without a jury because of allegations of jury tampering. A previous trial had been abandoned for that reason.
In 2007, following the arrests on different occasions of two of the present respondents, B and H, and the partial recovery from illness of T, three respondents stood their trial at the Central Criminal Court before His Honour Judge Roberts and a jury. This trial lasted for more than six months. By the time the judge came to sum up the jury had diminished to ten. After they had been in retirement for two days a note was sent to the trial judge which indicated that the jury had reached "on all defendants on all counts a very strong majority decision". As there was a Bank Holiday weekend ahead, the judge stated that he would not give a majority direction and take verdicts but, to assist the defence considering any submissions about the timing of such a direction he indicated that the verdicts were likely to be adverse to them. Nine Jurors returned to court after the Bank Holiday. A tenth juror said that he was under stress and refused to return to court. He was therefore discharged. With only nine jurors left, a majority veridct was no longer available and therefore the appropriate direction was not given. The jury was unable to reach unanimous verdicts. Pending a retrial the respondents were granted conditional bail.
To say the least, that was a very unfortunate series of events.
