Criminal evidence – Sexual offences – Corroboration. High Court of Justiciary: In an appeal by an appellant who was convicted of the offence of coercing another into being present during sexual activity by repeatedly exposing himself and masturbating in view of his next door neighbour on various occasions between 16 October and 16 November of 2017, only the final incident being spoken to by more than one witness, the court held that the summary sheriff was entitled to repel a submission of no case to answer, however while they might be different manifestations of a single course of conduct, each episode here was in fact a separate incident which required to be corroborated of itself, and accordingly the sheriff was not entitled to convict the appellant of four incidents rather than the one incident of 16 November 2017.
