Practice Relating to Rule 89. Violence to Life
In its written statement submitted to the ICJ in the Nuclear Weapons case in 1995, Costa Rica stated:
The human right to life has found support both within the United Nations Treaties, Declarations and Resolutions as well as in Regional and International Agreements.
Through the evolution from the Universal Declaration of Human Rights to the present time, the principles and articles, build upon each other to construct a strong structure where it is conclusive that the use of nuclear weapons violates the international law governing the Human Rights to Life and Health.
