From the judgement:
"There is no statutory requirement that male and female prisoners be accommodated in different establishments, but rule 12(1) of the Prison Rules 1999 provides that –
"Women prisoners shall normally be kept separate from male prisoners."
The population of a female prison may include persons who were born female and identify as such (referred to in this judgment as "women"); persons who were born male but identify as female, whether or not they have undergone any alteration of physical characteristics ("transgender women"); and transgender women who have obtained a GRC ("transgender women with a GRC"). It is important to the Claimant's case to note that both a transgender woman and a transgender woman with a GRC may retain male genitalia."
"Women prisoners shall normally be kept separate from male prisoners."
I am actually shocked by those prison rules because the inequality is already baked in in 1999. 'Women' vs males. Not female.
Were women's prisons never intended to be single sex? Where had transvestite or transsexual prisoners been housed before? Was it just that in 1999 they could not see where we would be 20 years later and the word "woman" was not contended ground? Were Press for Change consulted?
This is pre GRA so there was no legal reason for the fudge of language.
The judgement looks like it needs a good Barrakering, doesn't it?
So, to be clear, our current prison rules say Female-and-criminal-men-who-say-they-feel-like-women-and-men-with-the-paraphilia-of-transvestic-fetish-disorder-and-the-tiny-group-of-males-who-the-state-say-can-legally-call-themselves-female-even-though-they-still-may-have-penises prisoners shall normally (and what's with the normally? irrespective of their crime?) be kept separate from male prisoners.
Maybe the 1999 prison rules is the place to start change?
