Military Necessity and Humanity in International Humanitarian Law: Preserving the Delicate Balance

This chapter examines the international humanitarian law (IHL) principles of military necessity and humanity. It argues that the two principles undergird the entire body of IHL. Therefore, each individual IHL rule represents a delicate balance fashioned by States to accommodate both their legitimate need to be able to fight effectively on the battlefield and their desire to avoid unnecessary harm to combatants and the civilian population. However, the principles do not constitute norms which apply in addition to the existing rules, whether customary or conventional in nature. To interpret them in this manner would skew the balance upon which States have agreed.
