Practice Relating to Rule 15. The Principle of Precautions in Attack
Section D. Information required for deciding upon precautions in attack
Spain’s LOAC Manual (1996) states:
Information is one of the basic pillars on which a commander must base his decisions. A commander needs information about the presence of protected persons and objects in the zone of operation, the nature and location of medical establishments, the location of cultural and religious objects, nuclear power plants, concentrations of civilian persons, movements of populations, etc.
Spain’s LOAC Manual (2007) states:
Information is one of the essential pillars on which commanders base their decisions. Commanders must include in their information requirements the presence in the area of protected people and property, the nature and location of medical establishments, the location of cultural and religious property, nuclear power stations, concentrations of civilian population, population movements, etc.
Upon ratification of the 1977 Additional Protocol I, Spain declared with regard to Articles 51 to 58 inclusive:
It is the understanding [of the Spanish Government] that the decision made by military commanders, or others with the legal capacity to plan or execute attacks which may have repercussions on civilians or civilian objects or similar objects, shall not necessarily be based on anything more than the relevant information available at the relevant time and which it has been possible to obtain to that effect.
