Practice Relating to Rule 15. The Principle of Precautions in Attack
Section D. Information required for deciding upon precautions in attack
New Zealand’s Military Manual (1992), with respect to the standard by which to judge the duty to take all feasible precautions, states:
Any subsequent evaluation of conduct must focus on all the circumstances, including humanitarian and military considerations, as they appeared to decision makers at the time, rather than against an absolute standard.
Upon ratification of the 1977 Additional Protocol I, New Zealand stated:
In relation to Article 51 to 58 inclusive, it the understanding of the Government of New Zealand that military commanders and others responsible for planning, deciding upon, or executing attacks necessarily have to reach decisions on the basis of their assessment of the information from all sources which is reasonably available to them at the relevant time.
