Practice Relating to Rule 54. Attacks against Objects Indispensable to the Survival of the Civilian Population
Section B. Attacks against objects used to sustain or support the adverse party
In 1994, in reply to a questionnaire from the House of Representatives, Colombia’s Ministry of Foreign Affairs quoted Article 14 of the 1977 Additional Protocol II. It added:
What this article prohibits is the starvation of civilians. Therefore if one of the parties considers that an agricultural area with its crops, its livestock and its supply of clean water is supporting the military effort of the adverse party, or if it simply serves to feed the civilian population which is suspected of collaborating with the adverse party, that party can claim that it is meeting the objective of Article 14, that is, not starving the population, by moving the population concerned to another place.
