Family proceedings – Care proceedings. In the course of care proceedings concerning four children, findings of fact were made in relation to one of the children, Z. He had been discovered to have had the drug Olanzapine in his body. The judge found that the mother was sole perpetrator. The Court of Appeal, Civil Division, in dismissing the mother's appeal, held that the judge's conclusion about the administration of the Olanzapine discovered in Z's system by a test taken on 14 August 2013 had been neither his own speculation nor an unwarranted calculation or deduction of his own. It had been a proper inference drawn from the available factual evidence and the un-contradicted scientific opinion evidence. His conclusion was, accordingly, unassailable.
