I agree with Snowypeaks. I thought the position paper was a very clear and strong endorsement that sex means biological sex and not gender, which is defined separately. IOW, a transwoman is a man, not a woman, for the purposes of the treaties.
Excerpts:
-While not addressing or defining the terms “sex” or “gender”, many foundational human rights treaties, and declarations, including CEDAW, enshrine a prohibition of discrimination based on sex which can only be taken to mean as referring to biological sex
In General Recommendation No. 28, the CEDAW Committee defined “gender” as “socially constructed identities, attributes and roles for women and men and society’s social and cultural meaning for these biological differences resulting in hierarchical relationships between women and men [emphasis added]”. “This understanding of gender clarifies that the term ‘gender’ is not to be equated with women”. It is also clear that the CEDAW Committee did not equate a person who may identify as a woman and a man with someone who is a woman or a man – the latter being defined as either biologically male or female.
it is clear that sex and gender are two different concepts. However, international law does not permit any derogation to the prohibition of discrimination against women based on sex. Where tension may arise between the right to non-discrimination based on sex and non-discrimination based on gender or gender identity, international human rights law does not endorse an interpretation that allows either for derogations from the obligation to ensure non-discrimination based on sex or the subordination of this obligation not to discriminate based on sex to other rights . . .
It is my view that international human rights treaties, including CEDAW, prohibit such derogation under any circumstance, including during a public emergency.
Building on the implicit understanding that the word “woman” refers to biological females, the CEDAW Committee’s reference to lesbian women can only be understood to mean biological females that are attracted to biological females.
