Adopted on 18 December 2002 at the fifty-seventh

PREAMBLE
The States Parties to the present Protocol,
Reaffirming that torture and other cruel, inhuman or degrading
treatment or punishment are prohibited and constitute serious
violations of human rights,
Convinced that further measures are necessary to achieve
the purposes of the Convention against Torture and Other
Cruel, Inhuman or Degrading Treatment or Punishment (hereinafter
referred to as the Convention) and to strengthen the protection
of persons deprived of their liberty against torture and
other cruel, inhuman or degrading treatment or punishment,
Recalling that articles 2 and 16 of the Convention oblige
each State Party to take effective measures to prevent acts
of torture and other cruel, inhuman or degrading treatment
or punishment in any territory under its jurisdiction,
Recognizing that States have the primary responsibility
for implementing those articles, that strengthening the
protection of people deprived of their liberty and the full
respect for their human rights is a common responsibility
shared by all and that international implementing bodies
complement and strengthen national measures,
Recalling that the effective prevention of torture and other
cruel, inhuman or degrading treatment or punishment requires
education and a combination of various legislative, administrative,
judicial and other measures,
Recalling also that the World Conference on Human Rights
firmly declared that efforts to eradicate torture should
first and foremost be concentrated on prevention and called
for the adoption of an optional protocol to the Convention,
intended to establish a preventive system of regular visits
to places of detention,
Convinced that the protection of persons deprived of their
liberty against torture and other cruel, inhuman or degrading
treatment or punishment can be strengthened by non-judicial
means of a preventive nature, based on regular visits to
places of detention, Have agreed as follows:
