Criminal evidence and procedure – Human trafficking – Mutual corroboration – Sentencing. High Court of Justiciary: Refusing appeals against conviction and sentence by an appellant who was found guilty of eight offences of human trafficking, the court rejected contentions that the sheriff misdirected jury in relation to mutual corroboration in directing them that there was a legal sufficiency and that his use of the word 'rule' on twelve occasions, when describing mutual corroboration, amounted to a misdirection; furthermore it held that only a custodial sentence could have been regarded as appropriate and that the sheriff's selection of 3 years' imprisonment could not be described as excessive.
