Practice Relating to Rule 89. Violence to Life
In its oral pleadings before the ICJ in the Nuclear Weapons case in 1995, Qatar stated:
The right to life is one of the four non-derogable rights which constitute the “irreducible core” of human rights. This means that the right to life cannot be suspended by a State, even in times of public death. [sic] Although it is expected that in times of war human beings might perish, such killings should not exceed the limits of law.
