I see none of that in the judge's comments.
She does not imply that the law is wrong.
She is clear that strict liability is correct and states why the law is as it is.
She does not say that the girl's behaviour makes it acceptable. Indeed, she specifically says that her attitude is irrelevant to guilt. However, as a matter of law the fact that she consented is a factor to be taken into account when passing sentence.
"If she were a few months older" is again a factor to be taken into account when passing sentence. It does not alter the fact that there is a cut off age.
She does not say his spontaneous distress means he was contrite. She mentions it as supporting evidence that he genuinely believed she 16.
These are sentencing remarks. They rarely say much about the victim. However, the evidence is that the victim in this case has not suffered any distress as a result of what happened.
I suspect you are not used to reading sentencing remarks. These are fairly normal. The judge has laid out what happened and the reasons for conviction. She has then looked at mitigating and aggravating factors. Things such as the victim's consent (or lack thereof) come into play at this point and will always be mentioned. This does not mean the judge in any way disagrees with the law. It means the judge is doing her job.
