Please think about a transgender woman - that is a man
who has gone through all or part of a process to become a
woman. How comfortable or uncomfortable would you be for a
transgender woman to use female public toilets?
I wonder also what most would consider 'part of a process'?
Guidance from 'Press for Change: The UKs leading experts in Transgender Law'
The Explanatory Notes to the Act make it quite clear that 'gender reassignment' is to be considered a social process and not a medical process.
As such, the act protects anyone who is Intending to undergo, is undergoing, or has undergone gender reassignment even if they have not had or do not intend to have any medical gender reassignment treatments.
Initially the European Court of Justice used the phrase “intending to undergo, undergoing or having undergone gender reassignment” but s. 82 of the Sex Discrimination Act 1975 (as amended) now states that this refers to those people intending to transition, or who have transitioned to living permanently in the new gender role ‘under medical supervision’. Medical supervision is as little as going to the doctor and saying "I wish to undergo gender reassignment treatment, please could you refer me to be put on the waiting list for a clinical assessment”.
With the Equality Act 2010 under medical Supervision has been removed and is no longer required.
As such it is possible to say that “intending to undergo, undergoing or having undergone gender reassignment” now means in UK law; “intending to live permanently, or is already living permanently in the new gender role.”
