The first and most significant U.S. case involving command responsibility was that of General Tomoyuki Yamashita, commander of the Japanese forces in the Philippines in World War II, whose troops committed brutal atrocities against the civilian population and prisoners of war. Gen. Yamashita, who had lost almost all command, control, and communications over his troops, was nevertheless convicted by the International Military Tribunal in Tokyo based on the doctrine of command responsibility. The U.S. Supreme Court affirmed the decision, holding that General Yamashita was, by virtue of his position as commander of the Japanese forces in the Philippines, under an affirmative duty to take such measures as were within his power and appropriate in the circumstances to protect prisoners of war and the civilian population.361 General Yamashita was executed by hanging.
International and U.S. authorities have since set forth three elements to establishing liability for criminal acts pursuant to the doctrine of command responsibility:
1. There must be a superior-subordinate relationship.
2. The superior must have known or had reason to know that the subordinate was about to commit a crime or had committed a crime.
3. The superior failed to take necessary and reasonable measures to prevent the crime or to punish the perpetrator.362
U.S Army Field Manual 27-10, Section 501 states:
In some cases, military commanders may be responsible for war crimes committed by subordinate members of the armed forces, or other persons subject to their control. Thus, for instance, when troops commit massacres and atrocities against the civilian population of occupied territory or against prisoners of war, the responsibility may rest not only with the actual perpetrators but also with the commander. Such a responsibility arises directly when the acts in question have been committed in pursuance of an order of the commander concerned. The commander is also responsible if he has actual knowledge, or should have knowledge, through reports received by him or through other means, that troops or other persons subject to his control are about to commit or have committed a war crime and he fails to take the necessary and reasonable steps to insure compliance with the law of war or to punish violators thereof.
Similarly, the U.S. Department of Defense draft instructions for guidance to military commissions states: A person is criminally liable for a completed substantive offense if that person commits the offense, aids or abets the commission of the offense, solicits commission of the offense, or is otherwise responsible due to command responsibility, and provides the following elements:
1. The accused had command and control, or effective authority and control, over one or more subordinates;
2. One or more of the accuseds subordinates committed, attempted to commit, conspired to commit, solicited to commit, or aided or abetted the commission of one or more substantive offenses triable by military commission;
3. The accused either knew or should have known that the subordinate or subordinates were committing, attempting to commit, conspiring to commit, soliciting, or aiding and abetting such offense or offenses; [and]
4. The accused failed to take all necessary and reasonable measures within his or her power to prevent or repress the commission of the offense or offenses.363
The rule under customary international law is the same. According to an authoritative study by the ICRC, that rule is:
Commanders and other superiors are criminally responsible for war crimes committed by their subordinates if they knew, or had reason to know, that the subordinates were about to commit or were committing such crimes and did not take all necessary and reasonable measures in their power to prevent their commission, or if such crimes had been committed, to punish the persons responsible.364
A superior-subordinate relationship is clearest when there are formal rules, for example when legislation or a military chain of command specify the existence of a relationship. However, even in the absence of formal rules, a superior can have actual and effective control.365 Thus, civilian and political superiors, as well as those in military command, may be held liable under this doctrine.366 In establishing whether a superior-subordinate relationship exists, case law has found the following questions useful: What are the powers of influence of the alleged superior?367 What capacity does the superior have to issue orders?368 Does analysis of the distribution of tasks within any relationship demonstrate a superior-subordinate relationship?369
The superiors knowledge
A superior may be held liable under the command responsibility doctrine where he or she either knew, had reason to know, or should have known that crimes were being committed by his/her subordinates.370
According to A. P. V. Rogers, one of the foremost authorities on the laws of war, there are three ways of proving knowledge:
Rogers thus notes that If knowledge cannot be proved by direct evidence, it may be inferred from the surrounding circumstances, for example, the widespread nature, severity or notoriety of offences. Similarly, if he is told that a report deals with, say, the massacre of civilians by troops under his command, he is put under a duty to do something about it. He cannot simply turn a blind eye to it. He must give appropriate orders to his staff.
Rogers concludes that:
Actual knowledge may be difficult to prove, but can be inferred from the surrounding circumstances, especially if war crimes by those under command are so widespread as to be notorious, for example, when soldiers under command carry out sustained and frequent unlawful attacks, .Liability may also attach to a commander even if he did not actually know about the acts of subordinates but ought to have known about them and his failure in this respect constituted a dereliction of duty on his part, for example, if he is put on notice but fails to do anything about it.
Superior duty to take necessary and reasonable measures to prevent the crime or to punish the perpetrator
Superiors have both a duty to prevent and a duty to punish
the crimes of subordinate persons. These constitute distinct and independent
A superiors duty to punish arises after the commission of an offense. It is predicated upon offenses by others which have already occurred, not future offenses. Punishment is, therefore, intended to deter the commission of future offenses.

More recently, several decisions under the Torture Victim Protection Act of 1991 (28 U.S.C.S. § 1350) have applied the doctrine of command responsibility. See Hilao v. Estate of Ferdinand Marcos, 103.F.3d 767, 777-78 (9th Cir.1996); Kadic v Karadzic, 70 F.3d 232, 239, 242 (2d Cir. 1995); Paul v Avril, 901 F.Supp. 330,335 (S.D.Fla. 1994); Xuncax v. Gramajo, 886 F.Supp. 162, 171-172 (D.Mass. 1995). In Ford v. Garcia, 289 F.3d 1283 (11th Cir. Fla. 2002), for example, family members of victims of atrocities committed by members of the Salvadorian National Guard, filed a case in a Florida federal court against a general and the former minister of defense. The judge directed that the two generals could be held responsible for the crimes of their subordinates if the defendants were in effective command and if they knew or should have known that persons under their effective command were committing such crimes.

With respect to superior and subordinate relationships not described in paragraph (a) [military chain of command], a superior shall be criminally responsible for crimes within the jurisdiction of the Court committed by subordinates under his or her effective authority and control, as a result of his or her failure to exercise control properly over such subordinates, where:
(i) The superior either knew, or consciously disregarded information which clearly indicated, that the subordinates were committing or about to commit such crimes;
(ii) The crimes concerned activities that were within the effective responsibility and control of the superior; and
(iii) The superior failed to take all necessary and reasonable measures within his or her power to prevent or repress their commission or to submit the matter to the competent authorities for investigation and prosecution.

(a) actual knowledge, (b) such serious personal dereliction on the part of the commander as to constitute wilful and wanton disregard of the possible consequences, or (c) an imputation of constructive knowledge, that is, despite pleas to the contrary, the commander, under the facts and circumstances of the particular case, must have known of the offences charged and acquiesced therein.
