Legal justifications for gender parity on the bench of the International Court of Justice: An argument for evolutive interpretation of Article 9 of the ICJ Statute

The UN General Assembly and the UN Security Council should amend their rules of procedure to create gender parity on the bench of the International Court of Justice. Only 3.7 per cent of all judges on the ICJ have been women. The UN Charter, ICJ Statute, and long-standing practice of the Court underscore the importance of representation, but the focus has been on geographical representation. Using the law of international organizations, combined with the law of treaty interpretation and international human rights law, this article argues that Article 9 of the ICJ Statute should be interpreted to include a requirement of gender parity. Established practice, subsequent practice, and the UN’s multi-decade gender parity in staffing policy establish an evolutive interpretation of what is required to fulfil equality at the UN and the ICJ. The nomination and election procedures for ICJ judges are sufficiently flexible to facilitate this interpretation
