Protection against the effects of hostilities
Apart from a few provisions of limited scope, the Geneva Conventions do not deal with the general protection of civilian populations against the effects of hostilities. This matter came under The Hague Conventions, most of whose rules go back to 1907 and have from that time acquired a customary character and are still valid. But the evolution that has taken place since the beginning of this century in military technique and, in particular, extraordinary developments in aerial warfare has made it necessary to develop and make more specific the existing law of armed conflicts. This is the subject of Part IV of the First Protocol additional to the Conventions.
1. Fundamental principle and basic rules
The fundamental principle on which the law of armed conflicts is based is expressed as follows: In any armed conflict, the right of the Parties to the conflict to choose methods or means of warfare is not unlimited. Two basic rules follow from this principle. The first prohibits the use of weapons, projectiles and material and methods of warfare of a nature to cause unnecessary injury. The second, in order to ensure respect and protection for the civilian population and civilian property, obliges the Parties to the conflict to distinguish at all times between the civilian population and combatants, as well as between civilian property and military objectives and to direct their operations only against military objectives.
2. Definition of civilians and civilian Property
Any Person not belonging to the armed forces (see Chapter III, Section I) is considered as a civilian and the same applies in case of doubt as to his status. The civilian population comprises all persons who are civilians.
Civilian property is anything which is not a military objective, i.e. which by its nature, location, purpose or use does not effectively contribute to military action and whose total or partial destruction, capture or neutralization would not offer a definite military advantage in the circumstances ruling at the time. Thus, military equipment, a road of strategic importance, a supply column on its way to the army, a civilian building evacuated and reoccupied by combatants are military objectives. In case of doubt, a property which is normally assigned to civilian use should be considered as civilian and must not be attacked.
3. Protection of civilian persons and property
The prohibition of attacks on civilian persons and civilian property includes all acts of violence, whether committed in offence or defence. Attacks or threats of violence intended to terrorize the civilian Population are also prohibited.
The prohibition includes attacks launched indiscriminately. In particular these are attacks which are not directed or which cannot be directed, because of the methods or means of combat employed, at a military objective. Also considered as indiscriminate are attacks which treat as a single military objective a number of clearly separated and distinct military objectives located in a town, village or other area containing a similar concentration of civilians or civilian property. The same applies to attacks which cause incidental civilian losses and damage excessive in relation to the concrete and direct military advantage anticipated.
The presence or movements of the civilian population or individual civilians must not be used to try to shield military objectives from attack or to shield, favour or impede military operations.
The Fourth Convention provides for the conclusion by Parties to a conflict of local agreements for the evacuation from besieged or encircled areas of wounded, sick, disabled and old people, children and women in labour, and for the passage of ministers of all religions, medical personnel and equipment on their way to such areas.
The Protocol forbids starving civilian populations. Objects indispensable to the survival of civilian populations, such as foodstuffs, agricultural areas, crops, livestock, drinking water installations and supplies and irrigation works must neither be attacked, destroyed, removed nor rendered useless. A belligerent may depart from this rule only on its own territory and only if imperative military necessities require it to do so.
