Laws of war

The law of war (also law of armed conflict, LOAC) is law concerning acceptable practices relating to war. In cases other than civil wars, it is considered an aspect of public international law (the law of nations). The laws of war are divided into two categories:

*Jus in bello, law concerning acceptable conduct in war.
*Jus ad bellum, law concerning acceptable justifications to use armed force.

Sources of the laws of war

Attempts to define and regulate the conduct of individuals, nations, and other agents in war and to mitigate the worst effects of war have a long history. In medieval Europe the Roman Catholic Church promulgated teachings on just war, reflected to some extent in movements such as the Peace and Truce of God. The impulse to restrict the extent of warfare, and especially protect the lives and property of non-combatants continued with Hugo Grotius and his attempts to write laws of war.

Positive international humanitarian law consists of treaties (international agreements) which directly affect the laws of war by binding consenting nations and achieving widespread consent, including:

* The Hague Conventions of 1899 and 1907
* Geneva Protocol (1935)
* The United Nations Charter (1945)
* The Geneva Conventions and subsequent protocols, including
** First Geneva Convention "for the Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field" (first adopted in 1864, last revision in 1949)
** Second Geneva Convention "for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea" (first adopted in 1949, successor of the 1907 Hague Convention X)
** Third Geneva Convention "relative to the Treatment of Prisoners of War" (first adopted in 1929, last revision in 1949)
** Fourth Geneva Convention "relative to the Protection of Civilian Persons in Time of War" (first adopted in 1949, based on parts of the 1907 Hague Convention IV)
** Protocol I (relating to the Protection of Victims of International Armed Conflicts) and Protocol II (relating to the Protection of Victims of Non-International Armed Conflicts) (1977)

The opposite of positive laws of war is customary laws of war, many of which were explored at the Nuremberg War Trials. These laws define both the "permissive" rights of states as well as "prohibitions" on their conduct when dealing with irregular forces and non-signatories.

In addition, the Nuremberg War Trial judgment on "The Law Relating to War Crimes and Crimes Against Humanity" [ [http://www.yale.edu/lawweb/avalon/imt/proc/judlawre.htm Judgement : The Law Relating to War Crimes and Crimes Against Humanity] contained in the Avalon Project archive at Yale Law School.] held, under the guidelines Nuremberg Principles, that treaties like the Hague Convention of 1907, having been widely accepted by "all civilised nations" for about half a century, whereby then part of the customary laws of war and binding on all parties whether the party was a signatory to the specific treaty or not.

Interpretations of international humanitarian law change over time and this also affects the laws of war. For example Carla Del Ponte, the chief prosecutor for the International Criminal Tribunal for the former Yugoslavia pointed out in 2001 that although there is no specific treaty ban on the use of depleted uranium projectiles, there is a developing scientific debate and concern expressed regarding the impact of the use of such projectiles and it is possible that, in future, there will be a consensus view in international legal circles that use of such projectiles violate general principles of the law applicable to use of weapons in armed conflict. [ [http://www.un.org/icty/pressreal/nato061300.htm#IVA2 The Final Report to the Prosecutor by the Committee Established to Review the NATO Bombing Campaign Against the Federal Republic of Yugoslavia: Use of Depleted Uranium Projectiles] ] This is because in future it may be the consensus view that depleted uranium projectiles breaches one or more of the following treaties: The Universal Declaration of Human Rights; the Charter of the United Nations; the Genocide Convention; the United Nations Convention Against Torture; the Geneva Conventions including Protocol I; the Convention on Conventional Weapons of 1980; the Chemical Weapons Convention; and the Convention on the Physical Protection of Nuclear Material.

Purposes of the laws

It has often been commented that creating laws for something as inherently crimeful and lawless as war seems like a lesson in absurdity. However, based on the adherence to what amounted to customary international law by warring parties through the ages, it was felt that codifying laws of war would be beneficial.

Some of the central principles underlying laws of war are:
* Wars should be limited to achieving the political goals that started the war (e.g., territorial control) and should not include unnecessary destruction;
* Wars should be brought to an end as quickly as possible;
* People and property that do not contribute to the war effort should be protected against unnecessary destruction and hardship;

To this end, laws of war are intended to mitigate the evils of war by:
* Protecting both combatants and noncombatants from unnecessary suffering;
* Safeguarding certain fundamental human rights of persons who fall into the hands of the enemy, particularly prisoners of war, the wounded and sick, and civilians;
* Facilitating the restoration of peace.

Conduct of warfare

Among other issues, the laws of war address declaration of war, acceptance of surrender and the treatment of prisoners of war; military necessity along with "distinction" and "proportionality"; and the prohibition of certain inhumane weapons which cause unnecessary suffering.

It is a violation of the laws of war to engage in combat without meeting certain requirements, among them the wearing of a distinctive uniform or other distinctive signs visible at a distance, and the carrying of weapons openly. Impersonating soldiers of the other side by wearing the enemy's uniform is allowed, though fighting in that uniform, like fighting under a white flag, is perfidy which is forbidden, as is the taking of hostages.

Land warfare

The Law of Land Warfare is that part of the Laws of War applicable to the conduct of warfare on land (territory) and to relationships between belligerents and neutral states. This article, derived from public domain government sources, generally describes the law as internationally understood. The conduct of armed hostilities on land is regulated by the law of land warfare which is both written and unwritten.

Prohibitory effect

The law of war places limits on the exercise of a belligerent’s power mentioned under "Purposes" and requires that belligerents refrain from employing any kind or degree of violence which is not actually necessary for military purposes and that they conduct hostilities with regard for the principles of
humanity and chivalry.

Binding both on states and individuals

The law of war is binding not only upon States as such but also upon individuals and, in particular, the members of their armed forces.

Sources of the law

The law of war is derived from two principal sources:
* "Lawmaking Treaties" (or "Conventions"), such as the Hague and Geneva Conventions.
* "Custom". Not all the law of war derives from or has been incorporated in such treaties, which can refer to the continuing importance of customary law. (see Martens Clause). Such customary international law is established by the general practice of nations together with their acceptance that such practice is required by law.

Declaration of war

Some treaties, notably the UN charter (1945) Article 2, and some other articles in the charter, seek to curtail the right of member states to declare war; as does the older Kellogg-Briand Pact of 1928 for those nations who ratified it. The Kellogg-Briand Pact was used against those charged at the Nuremberg War Trials in Germany post-WW2 for waging an aggressive war.

Violations and applicability

Parties are bound by the laws of war to the extent that such compliance does not interfere with achieving legitimate military goals. For example, they are obliged to make every effort to avoid damaging people and property not involved in combat, but they are not guilty of a war crime if a bomb mistakenly hits a residential area.

By the same token, combatants that use protected people or property as shields or camouflage are guilty of violations of laws of war and are responsible for damage to those that should be protected.Fact|date=July 2007

Prohibitory effects

Well-known examples of such laws include the prohibition on attacking doctors or ambulances displaying a Red Cross, a Red Crescent or other emblem related to the International Red Cross and Red Crescent Movement (this sometimes leads to confusion when the British military is involved, where certain regiments use the English flag, which is also a red cross).Fact|date=March 2008 It is also prohibited to fire at a person or vehicle bearing a white flag, since that indicates an intent to surrender or a desire to communicate. In either case, the persons protected by the Red Cross or white flag are expected to maintain neutrality, and may not engage in warlike acts; in fact, engaging in war activities under a white flag or red cross is itself a violation of the laws of war known as perfidy.

Remedies for violations

During conflict, punishment for violating the laws of war may consist of a specific, deliberate and limited violation of the laws of war in reprisal.

Soldiers who break specific provisions of the laws of war lose the protections and status afforded as prisoners of war but only after facing a "competent tribunal" (GC III Art 5). At that point they become an unlawful combatant but they must still be "treated with humanity and, in case of trial, shall not be deprived of the rights of fair and regular trial", because they are still covered by GC IV Art 5. For example in 1976 foreign soldiers fighting for FNLA were captured by the MPLA in the civil war that broke out when Angola gained independence from Portugal in 1975. After "a regularly constituted court" found them guilty of being mercenaries, three Britons and an American were shot by a firing squad on July 10, 1976. Nine others were imprisoned for terms of 16 to 30 years.

Spies and terrorists may be subject to civilian law or military tribunal for their acts and in practice have been subjected to torture and/or execution. The laws of war neither approve nor condemn such acts, which fall outside their scope. However, nations that have signed the "UN Convention Against Torture" have committed themselves not to use torture on anyone for any reason. Citizens and soldiers of nations which have not signed the Fourth Geneva Convention are also not protected by it (Article 4: "Nationals of a State which is not bound by the Convention are not protected by it".), whether they are spies or terrorists. Also, citizens and soldiers of nations which have not signed and do not abide by the Third and Fourth Geneva Conventions are not protected by them. (Article 2, of both Conventions: " [The High Contracting Parties] shall furthermore be bound by the Convention in relation to [a Power which is not a contracting party] , if the latter accepts and applies the provisions thereof". note: emphasis added)

If someone is (or is suspected to be) a citizen or soldier of a nation which has signed or abides by the Fourth Geneva Convention (see Art. 2 and Art. 4 citations above), or is (or is suspected to be) a "prisoner of war" (POW) per the definitions of such "protected persons" in the Third Geneva Convention (see Art. 4 and Art. 5), the following applies: A POW who breaks specific provisions of the laws of war may be penalized, but not penalized worse than the tribunal would penalize its own soldiers for the same offense (and usually a disciplinary, not judicial, punishment if its own soldiers normally wouldn't be brought to trial for a particular offense) and POW's may not be penalized based on rank or gender, nor with corporal punishment, collective punishments for individual acts, lack of daylight, or torture/cruelty (GC IV, Art. 82 through Art. 88).

After a conflict has ended, persons who have committed or ordered any breach of the laws of war, especially atrocities, may be held individually accountable for war crimes through process of law. Also, nations which signed the Geneva Conventions are required to search for, then try and punish, anyone who has committed or ordered certain "grave breaches" of the laws of war. (see GC III, Art. 129 and Art. 130)

History has shown that the laws of war are traditionally more strictly applied to those defeated, as the victorious faction are placed in the role of policing themselves.Fact|date=July 2008 While it can be argued that the victors may be less strict on their own forces, it can also be argued that the signing of the treaties involved in the laws of war implies a good-faith promise to adhere to them equally. As with many facets of war, the aftermath and subsequent legal proceedings depend heavily on circumstance, and are different for each conflict.

There is an emerging trend in the US to hold private corporations civilly liable for aiding and abetting in war crimes, by knowingly providing substantial assistance in the commission of the crimes. Under international law, the mens rea element is knowledge, not intent that the crimes be carried out. This opens the door not only to hold private security contractors liable, but also other kinds of corporations which employ violent mercenary or terrorist groups as private security forces. Although conflict zones often lack functioning legal systems, and government may even have passed laws immunizing private mercenaries from criminal liability, aiding and abetting a war crime can still be the basis for civil liability in a foreign court with jurisdiction over the defendant corporation.
