International Humanitarian Law
"The body of international law — primarily the Geneva Conventions and their Additional Protocols — that regulates the conduct of armed conflict and seeks to limit its effects on people and property."
International Humanitarian Law (IHL), also known as the Law of Armed Conflict (LOAC) or jus in bello (law in war), is the branch of international law that applies in situations of armed conflict. Its primary purpose is to limit the suffering caused by war by protecting those who are not — or are no longer — participating in hostilities (civilians, wounded soldiers, prisoners of war) and by restricting the means and methods of warfare. The cornerstone of IHL is the four Geneva Conventions of August 12, 1949: (I) wounded and sick in field armies; (II) wounded, sick, and shipwrecked at sea; (III) prisoners of war (POWs); (IV) protection of civilians in wartime. These are supplemented by three Additional Protocols: Protocol I (1977, international conflicts), Protocol II (1977, non-international conflicts), Protocol III (2005, additional emblem — Red Crystal). Core IHL principles: (1) Distinction — parties must distinguish between civilians and combatants, and between civilian objects and military objectives; (2) Proportionality — civilian harm must not be excessive relative to anticipated military advantage; (3) Military Necessity — force is justified only to achieve legitimate military objectives; (4) Humanity — unnecessary suffering must be avoided; (5) Precaution — all feasible precautions must be taken to minimise civilian harm. IHL is administered and promoted by the International Committee of the Red Cross (ICRC), a neutral, impartial, and independent humanitarian organisation founded in 1863 and headquartered in Geneva. IHL applies regardless of the justice of the cause — it governs how wars are fought, not why (which is the domain of jus ad bellum). IHL covers both international armed conflicts (between states) and non-international armed conflicts (civil wars, armed groups). War crimes are serious violations of IHL and fall within ICC jurisdiction.
UPSC GS2 International Relations and GS4 Ethics questions on rules-based international order, laws of war, protection of civilians. Key org: ICRC (Geneva). Distinction: IHL (how war is fought) vs. jus ad bellum (right to go to war — UN Charter Article 51 self-defence). IHL applies to all parties regardless of who started the conflict.
- 1 IHL = Law of Armed Conflict = jus in bello — governs conduct during armed conflict
- 2 Four Geneva Conventions (1949): wounded/sick (land), wounded/sick (sea), POWs, civilians
- 3 Three Additional Protocols: 1977 (×2) and 2005
- 4 Core principles: Distinction, Proportionality, Military Necessity, Humanity, Precaution
- 5 ICRC (est. 1863, Geneva) — guardian and promoter of IHL, neutral and impartial
- 6 Applies to all parties in a conflict — regardless of who is the aggressor
- 7 IHL ≠ jus ad bellum (legality of use of force, governed by UN Charter)
- 8 Serious violations = war crimes, within ICC jurisdiction
India's conduct in counter-insurgency operations in J&K is sometimes evaluated against IHL principles — particularly AFSPA provisions — by human rights bodies. India maintains that AFSPA is consistent with IHL given the non-international armed conflict situation, illustrating the tension between state security imperatives and IHL obligations.
