46 96. Furthermore, the Court acknowledges that the Nuremberg Charter played an important role in establishing the elements that characterize a crime as a “crime against humanity.” This Charter provided the first articulation of the elements for such a crime.119 The original conception of such elements remained basically unaltered as of the date of the death of Mr. Almonacid-Arellano, with the exception that crimes against humanity may be committed during both peaceful and war times.120 On that basis, the Court acknowledges that crimes against humanity include the commission of inhuman acts, such as murder, committed in a context of generalized or systematic attacks against civilians. A single illegal act as those mentioned above, committed within the described background, would suffice for a crime against humanity to arise. In the same sense, the International Tribunal for the Former Yugoslavia rendered judgment in the Case of Prosecutor v. Dusko Tadic, when considering that “a single act committed by a perpetrator within a context of a generalized or systematic attack against the civil population brings about individual criminal liability, and it is not necessary for the perpetrator to commit numerous offenses in order to be considered responsible.”121 All these elements were already legally defined when Mr. Almonacid-Arellano was executed. 97. On the other hand, the International Military Tribunal for the trial of the Major War Criminals (hereinafter the “Nuremberg Tribunal”), which had jurisdiction to hear the cases of crimes included in the London Charter, stated that the Nuremberg Charter “is the expression of International Law existing at the moment of its creation, and to such extent, is in itself a contribution to International Law.”122 In this way, it provided recognition to the existence of an international custom, as an expression of international law, which prohibited such crimes. 119 Article 6 - The Tribunal established by the Agreement referred to in Article 1 hereof for the trial and punishment of the major war criminals of the European Axis countries shall have the power to try and punish persons who, acting in the interests of the European Axis countries, whether as individuals or as members of organizations, committed any of the following crimes: […] (c) CRIMES AGAINST HUMANITY: namely, murder, extermination, enslavement, deportation, and other inhumane acts committed against any civilian population, before or during the war; or persecutions on political, racial or religious grounds in execution of or in connection with any crime within the jurisdiction of the Tribunal, whether or not in violation of the domestic law of the country where perpetrated. 120 Cf.
