Ah ok thanks, that's quite different.
So to break it down legally:
Sex with a child of her age is strict liability--that means he is guilty even if he genuinely believed and had reason to believe she was over 16. He has been found guilty of this.
The controversy then is the judge's sentencing: the fact that he got community service and costs. The judge has said the case is exceptional, that there was no grooming and he genuinely believed she was older, and had good reason to do so (met on tinder, had car and house).
Basically the judge has discretion on sentencing and has believed his side of the story, so has given him a lenient sentence while stressing that the case is exceptional.
The short one word quotes from the judge like 'sexualised' are not value judgements but from part of the judgement where she has to give a factual narrative of what occurred. If she doesn't do this kind of thing correctly it could be the basis for him to appeal. So I wouldn't criticise her carefully selected choice of words, but to disagree with sentencing is totally legitimate
