Children proceedings – Decisions of children's hearing – Compulsory supervision order (CSO) – Frivolous and vexatious appeals. Sheriff Court: Following its refusal of an appeal by the mother of two children against decisions of a children's hearing to continue a CSO, including a measure of no contact between her and the children, the court heard a motion by the father of the children moving it to have the appellant deemed a frivolous and vexatious litigant, and after determining the correct approach to the relevant provision, while unable to conclude that the appeal was vexatious the court held that it was frivolous and that it should exercise its discretion to make an order requiring the appellant to obtain leave of the court before making another appeal under ss 154 or 161 of the Children's Hearings (Scotland) Act 2011 for a period of 12 months.
