I haven't read it all, but here are a few quotes:
Insofar as the Prisons Guidance allows SPS to accommodate trans prisoners in
prisons for the opposite biological sex, it is in conflict with the requirement that prison accommodation be provided separately for men and women. That constitutes a mis-statement of the law.
There is no positive obligation, in general terms, based on Article 2 or Article 3, to accommodate a trans prisoner in a prison for the opposite biological sex.
It is possible that, in an exceptional individual case, in a situation where there is a threat to life through suicide, it may be necessary to consider an argument that accommodation in a prison for the opposite biological sex is necessary and that rule 126 should be disapplied. Whether that could be achieved compatibly with the requirements of the EA 2010 cannot be determined in the abstract.
(Does that mean that if the TiM threatens suicide they may get placed in the women's prison?)
In all the circumstances, the Prisons Guidance is unlawful and the petitioner is
entitled to orders for declarator and reduction.
Yay.
