The use of solitary confinement must be strictly regulated and offer solid safeguards, including limitation in time to at least mitigate its negative effects. Whenever solitary confinement lasts more than a few hours there should be controls in place to avoid any systematic and/or discriminatory use of the measure.
Once the measure is decided upon, the person concerned must be promptly informed of the decision. The detainee must be able to challenge this decision through an internal complaints system or using legal recourse. The person concerned has the right to a lawyer.
To reduce the negative effects of solitary confinement, contacts with families, fellow inmates and chaplains must be maintained.
Measures should also be taken by the authorities to ensure that the material conditions in solitary are equivalent to conditions within the rest of the institution. In the event of disciplinary confinement, accommodation may be more limited, but must meet international standards, particularly regarding the size of cells, access to light, toilets, fresh air and the ability to exercise.
