Detention: solitary confinement
There is uncertainty as to whether solitary confinement by itself constitutes torture or cruel,
inhuman or degrading treatment or punishment.113 The HRC has expressed concern about the
use of solitary confinement for incarcerated persons following conviction.114
It has
commented that solitary confinement is “a harsh penalty with serious psychological
consequences”115 and is only justifiable in case of urgent need and for limited periods only. It
may otherwise amount to a breach of article 10(1) of the ICCPR. The Committee Against
Torture has also identified solitary confinement as a subject of concern, and has said that strict
conditions of solitary confinement may, in certain circumstances, amount to acts prohibited by
article 16 of the CAT.116
Whether solitary confinement constitutes torture will depend on the particular circumstances
of the individual case.117 In each case, regard must be had to the particular conditions, the
stringency of the measure, its duration, the objective pursued and its effects on the person
concerned.118 The European Commission on Human Rights has declared that absolute sensory
isolation combined with absolute social isolation constitutes inhuman treatment for which no
security requirements can form a justification.119
Non-voluntary solitary confinement should only ever be used as a punishment if proper
processes have been followed. It should never be for prolonged periods and there should be
the opportunity for independent review. There may be persons with special characteristics
