Practice Relating to Rule 90. Torture and Cruel, Inhuman or Degrading Treatment
Sweden’s Military Manual (1976) provides that military persons and civilians in the power of a party to the conflict shall not be tortured or mistreated. 
Sweden, Folkrätten – Internationella regler i krig, Blhang Svensk soldat, 1976, p. 28.
Sweden’s IHL Manual (1991) considers that the fundamental guarantees for persons in the power of one party to the conflict as contained in Article 75 of the 1977 Additional Protocol I are part of customary international law. 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section 2.2.3, p. 19.
The manual provides that “torture or inhuman treatment” is a grave breach of the 1949 Geneva Conventions. 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section 4.2, p. 93.
The manual also states: “Protected persons may not be exposed to any form of physical or mental coercion.” 
Sweden, International Humanitarian Law in Armed Conflict, with reference to the Swedish Total Defence System, Swedish Ministry of Defence, January 1991, Section 6.1.3, p. 122.
Sweden’s Penal Code (1962), as amended in 1998, provides that causing severe suffering to persons enjoying special protection under international law is a crime against international law. 
Sweden, Penal Code, 1962, as amended in 1998, 1962, Article 22(6).
In its judgment in the Arklöf case in 2006, Sweden’s Stockholm District Court stated:
[F]rom an international law perspective this is a matter of … cruel treatment, torture as well as humiliating and degrading treatment (articles 3 of Geneva Conventions I–IV, Additional Protocol II article 4). The compulsion that Arklöf exercised when he forced Tabakovic to walk out into a supposed minefield and to walk over a body can primarily be referred to as mental torture.
As previously stated, the international law rules that have been violated have customary status. These are serious transgressions. 
Sweden, Stockholm District Court, Arklöf case, Judgment, 18 December 2006, p. 61.
In its judgment in the Arklöf case in 2006, Sweden’s Stockholm District Court stated:
From an international law perspective, the acts include … cruel treatment, torture as well as humiliating and degrading treatment (articles 3 of Geneva Conventions I–IV, Additional Protocol II article 4).
It should be noted that torture is designated as the causing of serious physical or mental pain or such suffering, irrespective of whether the purpose is to obtain information, admissions or the execution of criminal acts or solely with the aim of punishing an individual, or has its grounds in discrimination of some type (see Customary International Humanitarian Law, Volume 1 p. 317 and ICTY, e.g. the case of Kunarac et al. (IT-96-23 & 23/1)). The definition within international humanitarian law is consequently more far-reaching than that which applies according to the Torture Convention mentioned by the prosecutor. 
Sweden, Stockholm District Court, Arklöf case, Judgment, 18 December 2006, p. 59.
