[5] The notice of appeal, quite unsatisfactorily, identifies as the ground for that appeal that the learned judge erred in making the order, without further particularisation. However, the appellant's submissions here identified five grounds, three of which concerned findings of fact said not to be open. The first of those was the learned primary judge's characterisation of the appellant's non-compliance with treatment as "wilful"; the second, his conclusion that supervision by the appellant's parents would lead to the destruction of their relationship, a finding which, it was said, was based on a misunderstanding of a reporting psychiatrist's evidence; and the third, a finding that the unanimous expert opinion was that the risk the appellant would commit another serious sexual offence was too great to allow his release. In addition, it was said, the judge acted on a wrong principle in making the order for continuing detention, when an order for supervised release was adequate to protect the community; and, insofar as the decision to make that order might have been founded on the need for treatment, there was insufficient evidence to warrant it.
