The prohibition
The prohibition of torture is absolute. It admits no exception for war, public emergency, or the gravity of the offence a detained person is suspected of. Article 3 of the European Convention on Human Rights states it in a single sentence and permits no derogation from it.
The United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, adopted in 1984, obliges states party to criminalise torture, to investigate allegations, and to refuse to return anyone to a country where they face it.
Why monitoring exists
Ill-treatment happens where it is not seen. Detention removes a person from the ordinary checks that would otherwise notice — a neighbour, a doctor of their choosing, a journalist, a court they can reach unaccompanied. Prohibition on paper does not replace those checks. Monitoring does: unannounced visits, private interviews, and access to custody records that nobody had time to prepare.
The Optional Protocol to the Convention against Torture, adopted in 2002, builds this into law. States party undertake to permit visits by an international body and to establish a National Preventive Mechanism of their own, with a standing right of access to every place where people are deprived of liberty.
What a visit looks at
- The first hours of custody, when the risk of ill-treatment is highest and the safeguards are thinnest.
- Whether a detained person was told their rights in a language they speak, and could act on them — a lawyer, a doctor, a call.
- Medical screening on arrival, and whether injuries are recorded by someone independent of the detaining authority.
- Material conditions: space, light, ventilation, heating, sanitation, and time out of cell.
- Solitary confinement and other forms of isolation — the grounds, the duration, and the review.
- Complaints: whether one can be made without going through the people it concerns, and whether anything follows from it.
How findings are used
A monitoring report is not a verdict. It records what was observed, sets it against the applicable standard, and says what should change and by when. Its force comes from specificity and from publication: a recommendation that names a facility, a practice and a deadline is harder to absorb into a general assurance of good intent.
