Gender Blender: Recent changes, such as the UK Supreme Court’s ruling that the term “woman” refers to those biologically female in specific contexts, widen the discrepancies in how gender is legally defined and recognised between European states. This interpretation of gender and sex creates further obstacles for people who might be intersex or non-binary. Considering that several Member States still require mental health assessments and a mandatory sex change to issue a Gender Recognition Certificate, how can Europe establish clear legal interpretations of gender for gender recognition and anti-discrimination purposes, while having a harmonised approach to protecting transgender and intersex individuals?
