About OPCAT
The Optional Protocol to the Convention against
Torture and other Cruel, Inhuman or Degrading
Treatment or Punishment (OPCAT) is an
international human rights treaty designed to
strengthen the protection of people deprived of
their liberty. It acknowledges that such people
are particularly vulnerable to ill-treatment, and
advocates that efforts to end ill-treatment focus
on prevention through a system of regular visits
to places of detention.
At the time of its adoption in 2002, OPCAT was
the first treaty to establish a dual international
and national system for the protection of
human rights. At the international level,
OPCAT established the Subcommittee for the
Prevention of Torture (SPT). The role of the
SPT is to periodically visit places of detention
in each of the States which ratify the treaty
(States Parties) and to make recommendations
to those States concerning the prevention
of ill-treatment. At the national level, OPCAT
requires States Parties to have in place a
‘national preventive mechanism’ (NPM), the role
of which is also to visit places of detention and
monitor the treatment of and conditions for
detainees. While the two visiting regimes – at
international and national levels – may overlap,
they are intended to complement each other
and be mutually reinforcing.
The scope of OPCAT is deliberately broad.
States Parties must allow the SPT and the
NPM to carry out visits to “any place under
its jurisdiction and control where persons are
or may be deprived of their liberty, either by
virtue of an order given by a public authority
or at its instigation or with its consent or
acquiescence”. 1
OPCAT defines deprivation of liberty as “any
form of detention or imprisonment or the
placement of a person in a public or private
custodial setting which that person is not
permitted to leave at will by order of any
judicial, administrative or other authority.” 2
About the SPT
Following the entry into force of OPCAT in
2006, the SPT began its work in February
2007. The role of the SPT is to visit places
of detention and make recommendations
to States Parties concerning the protection
of detainees against torture and other illtreatment. When they ratify OPCAT, States
Parties must grant the SPT unrestricted
access to all places of detention and allow
it to conduct private interviews with any
detainee it chooses, as well as any other
relevant people. Sanctions against anyone,
or any organisation, who speaks to the SPT
are prohibited. States Parties are also obliged
to provide the SPT with information on the
number of detainees and the number of
places of detention and their location, as
well as information relating to treatment and
conditions.
Following a visit, the SPT passes on its
recommendations and observations to
the State in confidence and, if relevant, to
the NPM. SPT reports may be published
at the request of the State Party. OPCAT
emphasises co-operation between the
SPT and the State Party and the need for
dialogue about the implementation of the
SPT’s recommendations.
