Practice Relating to Rule 70. Weapons of a Nature to Cause Superfluous Injury or Unnecessary Suffering
Article 20 of the draft Additional Protocol II, prohibiting the use of weapons of a nature to cause superfluous injury or unnecessary suffering, was deleted at the last moment by the CDDH, without any plenary debate, as part of a general revision of the 1977 Additional Protocol II. During the amendment voting at this stage, Saudi Arabia stated:
Article 20 (Basic rules) was rejected in a vote … since the legitimate party to an internal conflict is the de jure State. Obviously it will never try to exterminate its nationals or to damage its environment.
