Garrow’s aggressive style of cross-examination often uncovered circumstantial information that motivated juries to bend the rules and reduce the severity of punishment.
In episode 2 of series 3 of “Garrow’s Law” on BBC1, two men are accused of destroying silk looms in an act of industrial sabotage. When the jury bring in a verdict of not guilty on the one against whom his co-accused had pleaded King’s Evidence to secure his own release, Justice Buller told the jury to change their verdict – but they declined to do so. This is an example of what is called jury nullification.
