International criminal law already recognises persecution on gender grounds as a crime against humanity. It also recognises the crime of apartheid, but the Rome Statute's definition of apartheid is framed in terms of domination by one racial group over another.
Gender apartheid is therefore not currently a separate offence named in the Rome Statute.
A growing international campaign argues that this leaves a gap: gender persecution can criminalise serious acts committed against women, while the concept of gender apartheid is intended to describe an institutionalised system created to maintain their subordinate status.
Why would recognition matter?
Recognition could create clearer obligations for states to prevent and punish gender apartheid, investigate those responsible and avoid supporting its continuation.
It would also give women who have lived under these systems a stronger form of legal and public acknowledgement: that what happened to them was not simply unfair treatment or a series of separate restrictions, but part of a system recognised as criminal under international law.
