Resolution Sets Time-Bound Process for Adopting World’s First Stand-alone Treaty on Crimes Against Humanity

The United Nations Sixth Committee today adopted by consensus a resolution to advance a draft treaty on crimes against humanity to negotiations. Once adopted by the General Assembly next month, states will negotiate the first stand-alone treaty that explicitly addresses state responsibility to prevent and punish crimes against humanity.

Today’s resolution calls for a concrete and time-bound process consisting of preparatory sessions in 2026 and 2027, and three-week negotiations in 2028 and 2029, where a treaty will be finalized.

“Today’s resolution is a historic breakthrough toward a crimes against humanity treaty,” said Kelly Adams, legal advisor at the Global Justice Center. “Despite the proliferation of crimes against humanity around the world, negotiations on this treaty have been delayed time and again. But today’s decision paves the way for a treaty, which will offer crucial tools to prevent and punish these most extreme rights violations.”

The current draft treaty was developed over six years by the International Law Commission, a UN expert body charged with developing and codifying international law. For more information on the draft treaty, visit cahtreatynow.org.

Although crimes against humanity are defined under various treaties, including the Rome Statute that established the International Criminal Court, there is currently no treaty which expressly addresses states’ responsibilities to prevent or punish these crimes. This gap distinguishes crimes against humanity from war crimes and genocide, each of which has its own dedicated treaty (the Geneva Conventions and the Genocide Convention, respectively).

Negotiations for a new treaty present a unique opportunity to better advance justice for gender-based crimes, among other issues. In October 2023, a collection of human rights organizations and international law experts published a letter and several briefs that proposed changes to the draft treaty that focused on incorporating crimes like forced marriage, reproductive violence, and gender apartheid. A growing number of UN member states have expressed support for the inclusion of these crimes in a future treaty.

“At present, treaty provisions have yet to catch up to the lived experiences of victims of sexual and gender-based crimes and judicial findings that acknowledge this fuller scope of harms,” said Adams. “A strong, progressive, and survivor-centric treaty will ensure international and domestic systems are better equipped to prevent, punish, and ensure redress for systematic or widespread attacks on civilians involving sexual and gender-based violence.”

The General Assembly is expected to make a decision on the draft resolution in early December 2024.
