resulting from the acts of the States responsible. 171 Thus, in accordance with the basic principles of international law, in order to establish whether the State’s international responsibility is entailed in a case submitted to its consideration, the Inter-American Court must determine whether its agents have committed an act or omission, 172 which it will proceed to do below. 95. The Court also notes that the Paraguayan State itself recognized in the proceedings before the Commission, in a brief dated September 11, 2008, that the Public Prosecution Service had concluded that “acts of torture had been carried out” against several detainees, including the petitioner.” 173 The Court recalls that, according to international practice, when a party to a litigation has adopted a specific attitude that adversely affects its own position or benefits the position of the other party, under the estoppel principle, it cannot then assume another position contrary to the first. 174 96. Without prejudice to the above, the Court will proceed to analyze the acts to which Mr. López was subjected and consider whether they can be classified as torture pursuant to its case law (supra paras. 91 to 93). 97. With respect to the intentional nature of the acts in question, the Court holds that state agents carried them out deliberately and consciously. 98. With regard to the intensity of the physical or mental suffering endured, the body of evidence shows that Mr. López was subjected to physical and psychological punishments that were extremely intense and severe. When he was arrested, his hands were tied, he was blindfolded, and they laid him down on the ground. Several officers hit him on the soles of his feet numerous times. At the same time, Mr. López could hear another detainee being beaten and moaning from the pain being inflicted. 175 Mr. López was beaten throughout the morning. 176 These events were described not only by Mr. López, 177 but by several other individuals who witnessed them. Police officer V.C.G. said he was also held at the Specialized Group, where he saw Mr. López in “a terrible state, having clearly received blows to the neck, back and soles of his feet.” 178 Intelligence 171 Cf.
