The Nelson Mandela Rules and the use of restraints
The UN Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)13 provide
both principles and practical rules for the use of restraints in prisons. The overarching principle is that
“No prisoner shall be subjected to, and all prisoners shall be protected from, torture and other cruel,
inhuman or degrading treatment or punishment” (Rule 1), hence the absolute prohibition on any “use of
chains, irons or other instruments of restraint which are inherently degrading or painful” (Rule 47(1)).
Rule 47(2) provides that “Other instruments of restraint” – that is, ones that are not inherently degrading
or painful – may only be used “As a precaution against escape during a transfer, provided that they are
removed when the prisoner appears before a judicial or administrative authority” and “By order of the
prison director, if other methods of control fail, in order to prevent a prisoner from injuring himself or
herself or others or from damaging property”. Rule 48 further clarifies that instruments of restraint can
only be used after “lesser means of control” have proved ineffective, that the method used must be
the least intrusive one and be removed as soon as is no longer necessary, and that it must “never be
used on women during labour, during childbirth and immediately after childbirth.” Importantly, Rule 49
adds that “The prison administration should seek access to, and provide training in the use of, control
techniques that would obviate the need for the imposition of instruments of restraint or reduce their
intrusiveness.”
Despite the prohibitions of the Nelson Mandela Rules, some companies have manufactured a range
of degrading or painful mechanical restraints that severely restrict movement, some of which are likely
to cause severe physical pain as well as mental suffering or risk serious injury to the prisoner. They
include thumb cuffs, finger cuffs, leg irons, bar fetters, weighted leg restraints, neck restraints, and
restraints specifically designed to be bolted to prison walls, floors or ceilings. For example, the Omega
13 UN Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules), adopted by UN General Assembly
resolution 70/175, 17 December 2015, Annex.
