Turns out the prisoner has had no hormone treatment or surgery. And doesn't want any.

"It is understood that she has not undergone any transgender surgery, nor is she receiving hormonal therapy.
However, she was in possession of a gender recognition certificate by the time her case came before the court last July, and is now being accommodated with other female prisoners".
Sounds like the crimes were committed as a man and he was arrested as a man. While waiting for trial, the sex offender got a GRC by simply self-identifying as a woman which is a very straightforward process in Ireland.
Wonder if you have to declare pending court proceedings in Ireland as part of your GRC application? Probably not.
