For the first time in history; nuclear weapons will be ruled unlawful and prohibited; just as the world has done for other weapons of mass destruction such as biological and chemical weapons.

ACTION ALERT: Help Move Your Government
To Ratify the Nuclear Weapons Ban Treaty

Abolition 2000

(August 25, 2017) -- Democracy broke out at the UN this summer when 122 nations working closely with Civil Society adopted a treaty to ban nuclear weapons on July 7, 2017 after three weeks of negotiations; mandated by the UN General Assembly.

For the first time in history; nuclear weapons will be ruled unlawful and prohibited; just as the world has done for other weapons of mass destruction such as biological and chemical weapons!

Although the nine nuclear weapons states and their partners in the US nuclear alliance in NATO -- as well as Japan, Australia, and South Korea -- did not support the negotiations, the non-nuclear weapons states took the lead to make this new treaty to ban the bomb a reality.

The treaty requires 50 countries to sign and ratify it before it enters into legal force. It will be opened for signature at the UN General Assembly in New York on September 20, 2017.

Please see and download the Signing Kit here prepared by the UN Office for Disarmament Affairs (or click on the image below) to help you take effective action to enroll your government to sign and ratify the treaty.

See the ICAN website here, for more information on the text of the treaty and which nations voted for it.



Treaty on the Prohibition of Nuclear Weapons --
Signature and Ratification


The Treaty on the Prohibition of Nuclear Weapons includes a comprehensive set of prohibitions on participating in any nuclear weapon activities. These include undertakings not to develop, test, produce, acquire, possess, stockpile, use or threaten to use nuclear weapons.

The Treaty also prohibits the deployment of nuclear weapons on national territory and the provision of assistance to any State in the conduct of prohibited activities. States parties will also be obliged to prevent and suppress any activity prohibited to a State Party under this Treaty undertaken by persons or on territory under its jurisdiction or control.

The Treaty also obliges States parties to provide adequate assistance to individuals affected by the use or testing of nuclear weapons as well as to take necessary and appropriate measure of environmental remediation in areas under its jurisdiction or control contaminated as a result of activities related to the testing or use of nuclear weapons.

This brochure describes the procedures that States must follow in order to sign, ratify, accept, approve or accede to this treaty.

Included are model instruments that can be used for deposit with the Secretary-General of the United Nations.

1. Signature
The Treaty on the Prohibition of Nuclear Weapons will open for signature on 20 September 2017 at United Nations Headquarters in New York. Thereafter it can be signed at United Nations Headquarters in New York.

Under established international practice, only Heads of State, Heads of Government or Ministers for Foreign A airs are empowered, by virtue of their functions, to sign multilateral treaties on behalf of States without having to produce full powers to that effect.

Other representatives wishing to sign the Treaty must be in possession of appropriate full powers signed by one of these authorities. States wishing to sign the Treaty should, as necessary, provide the required full powers in advance to the United Nations Secretariat, Office of Legal Affairs.

By signing the Treaty on the Prohibition of Nuclear Weapons, a State signals its intention to become a party to it in the future. Once it has signed the Treaty, a State must not take any action that would undermine its object and purpose (see Article 18, Vienna Treaty on the Law of Treaties, 1969). Signing the Treaty does not make the State a party to it.

Signature does not legally bind the signatory State or require it to begin to implement the provisions of the Treaty. To become legally bound by a multilateral treaty, a signatory State must subsequently deposit its instrument of ratification, acceptance or approval. That State will then become a party in accordance with the entry into force provisions of the treaty in question.

States that have not signed a treaty may also consent to be bound by the treaty through the act of accession.

2. Consent to be bound (ratification, acceptance, approval and accession)
To become party to the Treaty on the Prohibition of Nuclear Weapons, a State must formally consent to be bound by the Treaty. This involves two steps: action by the concerned State at national level, and the notification to the depositary of consent to be bound.

A. Action by the national government
At the national level, a State must agree to adhere to the Treaty in accordance with domestic procedures for becoming party to treaties. This usually requires discussion within the country and action by its parliament and/or its executive.

B. Notification to the depositary
After domestic procedures have been followed and the decision to be bound by the Treaty has been taken, a State will need to prepare an instrument of ratification, acceptance, approval or accession.

A State that has signed the Treaty may consent to be bound by preparing an instrument of ratification, acceptance or approval.

A State that has not signed the Treaty may consent to be bound by preparing an instrument of accession.

For constitutional reasons, certain States use the terms 'acceptance' or 'approval' to describe their adherence to multilateral treaties. These terms have the same legal effect as ratification and consequently express a signatory State's consent to be bound by a treaty.

Instruments of consent to be bound by the Treaty (ratification, acceptance, approval or accession) must be deposited with the Treaty's depositary: the Secretary-General of the United Nations (contact: Office of Legal A airs, Treaty Section). e deposit of an instrument of consent to be bound with the depositary is a pre-requisite for the entry into force of a multilateral treaty for a State.

Some States can ratify treaties immediately, if their domestic procedures so permit. Nothing prohibits a State from depositing its instrument of ratification, acceptance or approval for the Treaty on the Prohibition of Nuclear Weapons on the same day as it signs the Treaty.

3. Entry into force
The Treaty on the Prohibition of Nuclear Weapons shall enter into force 90 days after 50 States have deposited their instrument of consent to be bound (ratification, acceptance, approval or accession). The specific date on which the Treaty becomes binding on a State is determined as follows:

a) For the first 50 States that deposit instruments with the United Nations Secretary-General, the Treaty will enter into force 90 days after the 50th instrument of ratification, acceptance, approval or accession is deposited.

b) For States that deposit their instrument thereafter, the Treaty will enter into force 90 days following the date on which they deposit their its instrument of ratification, acceptance, approval or accession with the United Nations Secretary- General.

4. Model instruments
Models of instruments to be deposited with the Secretary- General of the United Nations are annexed.
