The Optional Protocol to the United Nations Convention against Torture (OPCAT) is the international instrument establishing the Subcommittee on Prevention of Torture and entrusting national bodies – the National Preventive Mechanisms (NPMs) – with a role in the implementation of the Convention, as monitoring bodies.

NPMs have the mandate to regularly visit places of deprivation of liberty in their country, such as police stations, prisons and other detention facilities, psychiatric hospitals, and any other places where persons are not permitted to leave at their own will. NPMs also have the mandate to make recommendations to national authorities to work with them on the prevention of torture and ill-treatment and on the improvement of conditions of living in places of deprivation of liberty, for which they have a key role.

NPMs are empowered to perform their mandate effectively considering that they are independent bodies to which States Parties guarantee their functional independence as well as the independence of their personnel, ensure that their experts have the required capabilities and professional knowledge and provide them with the necessary resources for their adequate functioning.
