The means by which this crime could be perpetrated can include attempting to discredit potential jurors to ensure they will not be selected for duty. Once selected, jurors could be bribed or intimidated to act in a certain manner on duty. It could also involve making unauthorized contact with them for the purpose of introducing prohibited outside information and then arguing for a mistrial.
In the United Kingdom, the Criminal Justice Act 2003 allows for non-jury trials when there is danger of jury tampering, or where jury tampering has taken place. On 18 June 2009, the Court of Appeal in England and Wales made a landmark ruling that resulted in the Lord Chief Justice, Lord Judge, allowing the first-ever criminal trial to be held without a jury by invoking Section 44 of the Criminal Justice Act 2003. The case in question involved four men accused of an armed robbery at Heathrow Airport in February 2004. After three juries either failed to reach verdicts or were discharged, the fourth trial of the case took place before a single judge, and ended on 31 March 2010 with guilty verdicts for all four accused.
