I am going to get flamed for this but the judge is not a medical expert and has to consider and balance three different medical views The Cass Review, the WPATH guidance and the Australian Standards of Care and Treatment Guidelines.
His reasoning on which to follow is not unreasonable given he is in Australia not the UK. A judge in the UK would likely give more weight to Cass than the Australian guidance. It’s not surprising an Australian judge would do the opposite. WPATH (wrongly) have a lot of credibility e.g. the NHS uses the guidance.
The facts are that Cass is political. It was a response by the government of the day to a toxic debate. The fact that Baroness Cass is a woman of integrity and highly experienced means she conducted a medical/data driven independent review does not change that. There are GC people who feel the review was not neutral so both sides of the debate are not 100% happy - in my view usually a good sign.
He is clearly aware there will be detransitioners and these will result in court cases.
Ash’s pact with their 10 year old sister shows an understanding that Ash may be left sterile, may want children and may require an egg donor to become pregnant. No one expects a 10 year old to be held to this pact. It’s more it illustrates Ash’s comprehension of the negative aspects of PB I.e. that there are downsides.
The judge acknowledges Ash maybe left sterilised etc. but at 16 Ash has demonstrated they understand this and there is a point where a judge has to take onboard a child/young persons wishes. I hate the idea that surrogacy is seen as one of the judges solutions to this.
Essentially this judge is doing what is proposed in the UK as part of a trial. The Cass Clinical trials means some children will be given PB and this will be based on their individual cases.
I acknowledge my response is based on the article and not hearing all the evidence.
Finally, I don’t think anyone should be given PB but can see why in this case a 16 year old has been granted the right to take them.
