The GRC is supposed to be significant and offer the holder protections not given to non grc holders of the same sex.
So why doesnt the DBS treat the GRC holder more favourably than a person who hasnt been through this significant process? Why can't the DBS state that the person has been through this meaningful process? It already provides other very sensitive information.
I suspect its because with a female birth certificate, a female dbs and all other id in their new name, a grc holder is indistinguishable on paper from a woman. And if the holders 'passes' as the opposite sex, the dbs is a significant factor in a male person having access to female only employment, or treated as female in the workplace.
All other people going through the service will have their orginal birth certificate and can be outed that way.
The dbs will say its the employers responsibility to confirm sex through the birth certificates or grc. The two certificates arent comparable in that its odd for someone to claim that they dont have a bc, but not that they dont have a grc. Thats why i think the system is designed to help men conceal that they have a grc.
The dbs checks only crimal history, and is not a design to confirm sex, therefore shouldnt have sex listed, especially when they allow anyone to request the wrong one to be stated.
