My point was generally that I think (and again may be different in secondary vs primary care) that Mrs A et al should be able to cite examples where we don’t routinely expect a child under 16 to have capacity to consent and demonstrate that as PBs are equally if not more serious it should be expected that children will not routinely be able to consent to taking PBs
I definitely agree that that would be very helpful. The sterilisation analogy made by PPs would be a good one - would the court expect a child under 16 to be able to consent to an elective treatment that causes sterilisation? - perhaps chemo could be used as the analogous situation? If the court feels that a child can't consent to chemo that may sterilise her under Gillick, even though the chemo could be life-saving, it would surely follow that she can't consent to PBs?
However I am not sure in what detail the court will examine the medical evidence on PBs. Will it be a fairly cursory overview - which would be easier for the Tavi to defend, I would think, or will the hearing examine the case for and against PBs in detail, in order to determine whether or not Gillick competence is applicable? As I said upthread, I am not a lawyer, but my understanding of requests for judicial review is that they are usually based on whether a proper process has been followed on reaching a policy decision, rather than questioning the policy itself. If there are any lawyers reading this thread, it would be interesting to know their views.
