My reading of it is that this is such cutting edge medicine that the NHS has not yet come up with any specific guidelines.
Where there are no guidelines, the doctor has to show that:
- They acted in what they sincerely believed, using their clinical judgement, was the best interests of the patient.
- They explained the treatment and all possible side effects to the patient (or in this case the parents) who then gave their consent, in the knowledge that there were no specific protocols to follow.
Having looked at the case, they have concluded that Dr Webberley hasn't committed any offence and therefore can go back to practising. It's pretty much a technicality, rather than any kind of ethical judgement.
I think what happens next is what will make the difference. I suspect that now this has been raised, the NHS will take steps to put protocols in place. This is their chance, should they so desire, to clip Dr Webberley's wings. They could, for example, ask for input from the doctors at the Paediatric Endocrine Unit, University College Hospital London who complained about her. They might, for example, set a specific minumum age for treatment so that anyone working in the NHS would have to follow that rule or face the consequences.
However, given the current political climate... to quote from the page you linked: "In 2016, the Women and Equalities Committee report on Transgender Equality concluded that the transgender community is being let down by the NHS." it seems more likely that Dr Webberley herself, as someone at the forefront of this medicine, might be heavily involved in writing the new protocols.
I can't be sure. I could be misjudging the NHS. But my suspicion is that the paediatricians who reported her will be tearing their hair out in the same way we are. The heavy hand of the trans-lobby will drive this forward even though there are many educated people who feel it is unsafe and are questioning the ethics of practising experimental medicine on vulnerable children.
This statement in particular (again from the linked page) has trans-lobby written all over it and it's clear that the tribunal have taken their pressure into account as evidence. “The MPTS took into consideration all of the new information available and the considerable support sent into the GMC from families, patients and voluntary sector members, who recognise the urgent need within the transgender community. Transgender patients face discrimination and barriers at every turn, it has long been my position that access to healthcare should not be one such barrier.”
