“The overriding obligation of the court is to act in the best interests of X. In the decisions in the Court of Appeal in In re R and In re W, and there is more recent authority to the similar effect, it has been made clear that, in the final analysis, the court has to take its own decision as to what is in the best interests of a young person and that, in an appropriate case, even if that young person is Gillick competent, it may be appropriate for the court to decide, with regret, but nonetheless firmly, not to give effect to the strongly held views and the strongly held religious beliefs of that young person. That is something the court is very slow to do. It is something the court is very reluctant to do and it will do it only - I put the matter descriptively rather than definitively - where there is clear evidence of a serious risk to health or possible death if the court does not intervene.”
