'A male who has a GRC stating that he is legally a woman is initially placed in a women’s prison. Conviction, offending history and anatomy are not taken into consideration. If he poses a risk to or is at risk from the female prisoners and the risk is too high to manage in a women’s prison, his case is referred to a Transgender Complex Case Board.
Theoretically, a decision may be to transfer him to a men’s prison. However, in assessing this risk he is still ‘treated as a woman’. This means he can only be transferred to a men’s prison if that same decision would be made for a female prisoner. In practice, however, women are never held in the male estate: the risk to their safety would be too great to manage.
Treating a male prisoner with a GRC as a woman extends to risk assessment. We are repeatedly told that male prisoners are thoroughly risk assessed to ensure the safety of female offenders. However, this is not the case.
The OASys Sexual Reoffending Predictor Score, OSP for short, is used for adult men who have been convicted of sexual or sexually motivated offences. It is not for use with female sexual offenders. Neither is it used for male sexual offenders with a GRC, because these prisoners are assessed as women. There is no alternative risk assessment tool for use with women who have been convicted of sexual offences.'
