Criminal evidence and procedure – Mutual corroboration – Moorov doctrine. High Court of Justiciary: Refusing an appeal by an appellant who was convicted of a series of sexual offences committed against two boys, the court rejected a contention that one boy's evidence in respect of charges of lewd and libidinous practices and indecent assaults could not corroborate the other boy's evidence in respect of a charge of sodomy and that a no case to answer submission should have been sustained, holding that there were not such significant differences in the character of offences that the evidence was insufficient to entitle a jury to conclude that the appellant was systematically pursuing a course of conduct towards the two complainers.
