From what I understand, the point of law being made that the court cannot decide by judicial review, whether Gillick competence is possible or not, based on age-bands as laid out by the previous court, as every single case has to be assessed on its own merits.
So even with poorly-evidenced medicine, which causes enormous harm, it isn’t up to the courts to designate or limit who might be considered competent. Presumably the judges must make the assumption that the medics are assumed to be responsible and skilled. You can challenge an individual case, but not put a more general stop to the rest.
So even if the judges decide that what’s being done is criminally bad, they might still conclude that legally it’s not up to them to draw up guidelines that doctors and medical bodies should be creating.
Which suggests to me that it may turn out that the only way to challenge this situation is through individuals suing the hospitals and hoping that enough damage is done that the medical pathways are changed.
Hope I’m wrong, but it sounds like it may be an important point of law: that judicial review is the wrong way to challenge this.
