Practice Relating to Rule 44. Due Regard for the Natural Environment in Military Operations
In its written statement submitted to the ICJ in the Nuclear Weapons case in 1995, Egypt stated that it considered the principle whereby every State must ensure that activities within its jurisdiction or under its control do not cause damage to the environment to be a “general rule”. Referring to the 1972 Stockholm Declaration on the Human Environment and the 1992 Rio Declaration, in which this rule was stated, Egypt argued that they “must be seen as declaratory of evolving normative regulation for the protection of the environment”.
