Dear friends,

UNFOLD ZERO welcomes the 25th anniversary of the historic 1996 International Court of Justice Advisory Opinion on the Legality of the Threat or Use of Nuclear Weapons, and encourages you to join the important anniversary event organised by the International Association of Lawyers Against Nuclear Arms (IALANA). See below for the program.

Representatives of IALANA and civil society greet the New Zealand Attorney General as he arrives at the Peace Palace (International Court of Justice) in the Hague to deliver New Zealand's oral statement in the ICJ case on the Threat or Use of Nuclear Weapons, November 9, 1995.


On 8 July 1996, the International Court of Justice (ICJ) handed down its Advisory Opinion on the legality of the threat or use of nuclear weapons. It was the first authoritative international judicial opinion on nuclear weapons since their development in the 1940s.

The ICJ affirmed that "the threat or use of nuclear weapons would generally be contrary to the rules of international law applicable in armed conflict, and in particular the principles and rules of humanitarian law," but with a caveat that "the Court cannot conclude definitively whether the threat or use of nuclear weapons would be lawful or unlawful in an extreme circumstance of self-defence, in which the very survival of a State would be at stake."

The Court also affirmed that "There exists an obligation to pursue in good faith and bring to a conclusion negotiations leading to nuclear disarmament in all its aspects under strict and effective international control".


July 8 online anniversary event

In this anniversary event, leading international lawyers and activists, professors of international law and experts on arms control and disarmament law will discuss the importance of the Advisory Opinion and its relevance for the present day struggle towards nuclear disarmament. 

The webinar will also address more recent developments, such as the Treaty on the Prohibition of Nuclear Weapons and General Comment no. 36 on the right to life of the UN Human Rights Committee, which has opened the door to challenging nuclear armed and allied states policies amongst the broader human rights community and in the UN Human Rights Bodies. See, for example, Nuclear weapons violate the Right to Life: Using UN Human Rights Committee General Comment 36 in grassroots actions and campaigns and Canadian and French nuclear weapons policies challenged in the UN Human Rights Committee.

Finally, the event will address the question of what lessons can be drawn from the opinion regarding achievement of a world without nuclear weapons.


Inspiration for an ICJ case on climate change

The 1996 ICJ advisory opinion has provided precedent, supportive legal arguments and inspiration for a number of subsequent legal actions and initiatives, inlcuding a new campaign from the World's Youth for Climate Justice and Normandy Chair for Peace to take the issue of climate change to the ICJ. For more information see the animated video introduction to ICJ and the Climate campaign and the facebook recordings of the recent webinar on the initiative at Session A (Americas/Europe/Africa) and Session B (Asia/Pacific).
