seclusion and restraint by united nations treaty
bodies and special rapporteurs
Report of the Special Rapporteur on torture and other cruel, inhuman or
degrading treatment or punishment, U.N. Doc. A/63/175 Annex (28 July 2008)
(Manfred Nowak)
• “The use of solitary confinement should be absolutely prohibited in the
following circumstances:
˚˚ For death row and life-sentenced prisoners by virtue of their sentence.
˚˚ For mentally ill prisoners.
˚˚ For children under the age of 18.”
• “Furthermore, when isolation regimes are intentionally used to apply
psychological pressure on prisoners, such practices become coercive and
should be absolutely prohibited.”
• “As a general principle solitary confinement should only be used in very
exceptional cases, for as short a time as possible and only as a last resort.”
Report of the Special Rapporteur on torture and other cruel, inhuman or
degrading treatment or punishment, U.N. Doc. A/66/268 (5 August 2011)
(Juan Mendez)
• “… the social isolation and sensory deprivation that is imposed by some

hours a day. Of particular concern to the Special Rapporteur is prolonged
solitary confinement, which he defines as any period of solitary confinement
in excess of 15 days… because at that point, according to the literature
surveyed, some of the harmful psychological effects of isolation can become
irreversible.”
• “…the longer the duration of solitary confinement or the greater the
uncertainty regarding the length of time, the greater the risk of serious
and irreparable harm to the inmate that may constitute cruel, inhuman or
degrading treatment or punishment or even torture.” [58]
• “Solitary confinement, when used for the purpose of punishment, cannot
be justified for any reason, precisely because it imposes severe mental pain
and suffering beyond any reasonable retribution for criminal behaviour and
