Practice Relating to Rule 70. Weapons of a Nature to Cause Superfluous Injury or Unnecessary Suffering
In its written statement submitted to the ICJ in the Nuclear Weapons (WHO) case in 1994, Samoa stated:
The use of nuclear weapons by a state in war or other armed conflict would be a violation of international customary law and conventions, including the Hague Conventions and the Geneva Conventions. Such law and conventions prohibit the use of weapons … which cause unnecessary suffering.

In its written statement submitted to the ICJ in the Nuclear Weapons case in 1995, Samoa stated that it “believes that the prohibition of the use or threat of use of nuclear weapons has been achieved under general international law. It has occurred by the cumulative effect of a series of multilateral treaties and of a series of resolutions of the General Assembly”, including the 1868 St. Petersburg Declaration, the 1907 Hague Convention (IV) and the 1977 Additional Protocol I.
