Unmasking the Challenges
International human rights law and international humanitarian law absolutely prohibit all forms of torture and cruel, inhuman, or degrading treatment (CIDT) at all times and against anyone, even the worst of criminals. International criminal law moreover provides for the individual criminal responsibility of perpetrators. Nevertheless, there remains a number of legal and practical challenges to overcome in order to ensure the effectiveness of this prohibition. The most visible challenge pertains to the implementation of the prohibition not only in domestic law but also in the concrete practice of law enforcement officials and other State agents. Other—less visible and insufficiently discussed—challenges concern laws and practices that may indirectly impact the effectiveness of the prohibition of torture and CIDT and whose acceptability under public international law is not crystal clear. For instance, is the prohibition of using evidence obtained through torture/CIDT (so-called exclusionary rule) absolute and applicable in all cases? How far does the international law obligation to prosecute and punish torture/CIDT perpetrators go? To what extent may individual perpetrators of torture/CIDT invoke mitigating circumstances or even justifications to avoid or diminish punishment for the commission of such acts in extreme circumstances? Does the passing of lenient sentences upon individual perpetrators of ill-treatment entail the responsibility of the State as a failure to punish? The present chapter will discuss these issues in light of contemporary international practice of various human rights bodies (treaty bodies and UN special procedures) and international/mixed criminal courts and tribunals.
