Former insurance worker Craig Boath, 29,is serving a sentence of almost 10 years behind bars after being found guilty of sharing indecent images of children with other men.
His lawyers are now believed to be examining the decision given yesterday by the Scottish Criminal Cases Review. The body has referred Boath's case to the High Court after deciding the charges against him should have been restricted to sharing the images with one other person, rather than several.
It said that on this basis, the jury's verdict at the trial at the High Court in Edinburgh in 2009 may have resulted in a miscarriage of justice. His lawyers can now lodge an appeal.
Boath, of Dundee, was among six men convicted of conspiring to participate in the sexual abuse of children and child pornography offences. Two others, Neil Strachan and James Rennie, were also found guilty of conspiring to abuse youngsters, as were three other members of the gang.
