International Humanitarian Law, Geneva Conventions and Laws of Armed Conflict

International Humanitarian Law, also known as the Law of Armed Conflict or jus in bello, regulates conduct during armed conflicts. It limits the effects of war by protecting persons who are not, or are no longer, taking part in hostilities. It also restricts the means and methods of warfare through treaties such as the Hague Conventions, the Geneva Conventions of 1949, and their Additional Protocols.

Origins and Historical Development

Early customary rules of warfare existed across ancient civilizations, including the codes in the Mahabharata, the Laws of Manu, and Islamic jurisprudence during the Middle Ages. Modern treaty-based codification began in the nineteenth century.

Lieber Code (1863)

Promulgated during the American Civil War by President Abraham Lincoln, General Orders No. 100 (the Lieber Code) represented the first modern written code regulating the conduct of land warfare. It established rules on military necessity, the humane treatment of prisoners of war, and the protection of civilians.

The Red Cross and the 1864 Geneva Convention

Swiss businessman Henry Dunant witnessed the aftermath of the Battle of Solferino in 1859. His book, A Memory of Solferino, led to the founding of the International Committee of the Red Cross (ICRC) in 1863. In 1864, twelve states signed the original Geneva Convention for the Amelioration of the Condition of the Wounded in Armies in the Field, adopting the Red Cross emblem as a neutral protective sign.

The Hague Conventions (1899 and 1907)

The Hague Regulations focused primarily on “Hague Law”—the rules governing permissible means, weapons, and methods of warfare. They banned specific weapons, including expanding bullets and poison gas, while defining lawful combatants and the status of occupied territories.

The Four Geneva Conventions of 1949

Adopted in the aftermath of World War II, the four Geneva Conventions of August 12, 1949, modernized and expanded humanitarian protection.

• First Geneva Convention: Protects wounded and sick members of armed forces in the field, as well as medical and religious personnel, medical units, and medical transports.
• Second Geneva Convention: Adapts the protections of the First Convention to maritime warfare, protecting wounded, sick, and shipwrecked members of armed forces at sea and hospital ships.
• Third Geneva Convention: Governs the treatment of Prisoners of War (POWs). It mandates humane conditions, prohibits torture or coercion during interrogation, requires release and repatriation after hostilities end, and grants the ICRC access to detention facilities.
• Fourth Geneva Convention: Focuses on the protection of civilian populations during armed conflict and under foreign military occupation. It strictly prohibits collective punishment, reprisals against civilians, hostage-taking, and deportations.

Common Article 3

Article 3, identical in all four 1949 Conventions, serves as a “treaty in miniature” for non-international armed conflicts (civil wars and internal rebellions). It mandates humane treatment for all non-combatants, bans murder, mutilation, torture, and outrages upon personal dignity, and requires care for the sick and wounded without discrimination.

Additional Protocols

Three Additional Protocols supplement the Geneva Conventions to address modern warfare methods and irregular combatants.

• Additional Protocol I (1977): Strengthens protection for victims of international armed conflicts. It clarifies rules against attacks on civilian objects, dams, nuclear plants, and the natural environment, while broadening the definition of lawful combatants to include national liberation movements.
• Additional Protocol II (1977): Extends specific legal protections to victims of non-international armed conflicts occurring between state armed forces and organized dissident armed groups with territorial control.
• Additional Protocol III (2005): Created an additional protective emblem—the Red Crystal—free of religious, national, or political connotations, alongside the Red Cross and Red Crescent.

Core Principles of the Law of Armed Conflict

International Humanitarian Law operates on five fundamental principles that govern battlefield decisions.

International Humanitarian Law versus International Human Rights Law

IHL and International Human Rights Law (IHRL) are complementary legal frameworks, but they differ in scope and legal operation.

International Criminal Law and War Crimes

Violations of the Geneva Conventions classified as “grave breaches” constitute war crimes subject to universal jurisdiction.

• Rome Statute (1998): Established the International Criminal Court (ICC) in The Hague. It exercises jurisdiction over four core international crimes: genocide, crimes against humanity, war crimes, and the crime of aggression.
• Ad Hoc Tribunals: The UN Security Council created the International Criminal Tribunal for the former Yugoslavia (ICTY) in 1993 and the International Criminal Tribunal for Rwanda (ICTR) in 1994 to prosecute individuals for serious violations of international humanitarian law.
• Universal Jurisdiction: Allows national courts of any state to prosecute individuals accused of grave breaches of the Geneva Conventions, regardless of where the crime occurred or the nationality of the perpetrator or victims.

India and International Humanitarian Law

• India ratified the four Geneva Conventions of 1949 on October 16, 1950.
• The Indian Parliament passed the Geneva Conventions Act, 1960, to implement the conventions into domestic law and punish grave breaches.
• India has not signed or ratified Additional Protocol I (1977) or Additional Protocol II (1977), citing security concerns regarding the legal status of non-state combatants and national liberation groups.
• India is not a party to the 1998 Rome Statute of the International Criminal Court.
• The Indian Armed Forces maintain dedicated Human Rights Cells within the Army Headquarters and lower formations to monitor compliance with domestic and international norms during operations.

Key Facts on International Humanitarian Law

• Henry Dunant shared the first Nobel Peace Prize in 1901 with Frédéric Passy for his role in establishing the Red Cross.
• The International Committee of the Red Cross is a private Swiss organization that acts as an independent, neutral intermediary in armed conflicts.
• Universal participation exists for the four Geneva Conventions of 1949, with 196 state parties making them universally ratified treaties.
• The St. Petersburg Declaration of 1868 was the first formal agreement prohibiting the use of explosive projectiles under 400 grams.
• The Martens Clause, introduced in the preamble to the 1899 Hague Convention II, states that populations remain under the protection of the principles of the law of nations, humanity, and public conscience even in situations not covered by written treaties.
• Medical personnel, hospital staff, and military chaplains are considered non-combatants under the First Geneva Convention and cannot be made the object of attack.
• The 1925 Geneva Protocol prohibited the use of chemical and biological weapons in international armed conflicts.
• The emblem of the Red Crystal was adopted under Additional Protocol III in 2005 to provide a non-religious alternative to the Red Cross and Red Crescent.
• Jus ad bellum refers to the conditions under which states may resort to war or force, whereas jus in bello governs the conduct of parties during an active armed conflict.
• Grave breaches of the Geneva Conventions include wilful killing, torture or inhuman treatment, extensive destruction of property not justified by military necessity, and unlawful deportation or transfer.
