Article 3 ECHR: Torture, Inhuman and Degrading Treatment

Article 3 is one of the few absolute rights in the Convention. This note covers the threshold, the three categories, why no balancing is allowed, and the State’s duty to protect.

By Aoibheann Nic Eochaidh · Irish law · free study note · For Irish law students and exam revision. · updated 29 October 2026
In short: Article 3 prohibits torture and inhuman or degrading treatment or punishment in absolute terms. Ill-treatment must reach a minimum level of severity; once it does, there is no exception, no justification and no derogation.

The threshold and the absolute rule

In Ireland v United Kingdom, App no 5310/71, 18 January 1978; Series A no 25 ECtHR · persuasive in Irish courts the Court held that ill-treatment must attain a minimum level of severity, assessed on all the circumstances, such as duration, physical or mental effects and, in some cases, the sex, age and state of health of the victim. Article 3 prohibits ill-treatment in absolute terms, irrespective of the victim’s conduct, with no exception and no derogation.

The absolute rule holds even against terrorism and threats to life. In Chahal v United Kingdom, App no 22414/93, 15 November 1996 ECtHR · persuasive in Irish courts and later cases the Court refused to balance the risk to the person against the reasons for expelling him. In Gäfgen v Germany, App no 22978/05, 1 June 2010 ECtHR · persuasive in Irish courts threats of considerable pain made to find out where a kidnapped child was were inhuman treatment, even though a life was at risk.

Torture, inhuman and degrading treatment

Torture carries a special stigma attaching to deliberate inhuman treatment causing very serious and cruel suffering. In Selmouni v France, App no 25803/94, 28 July 1999 ECtHR · persuasive in Irish courts the Court said that, because the Convention is a living instrument, acts classified in the past as inhuman and degrading treatment could be classified differently in future. Violence in police custody, taken as a whole, was torture.

Degrading treatment humiliates or debases. In Tyrer v United Kingdom, App no 5856/72, 25 April 1978; Series A no 26 ECtHR · persuasive in Irish courts judicial birching of a 15-year-old was degrading punishment. In Bouyid v Belgium, App no 23380/09, 28 September 2015 ECtHR · persuasive in Irish courts the Grand Chamber held that any physical force against a person in custody not made strictly necessary by his own conduct is in principle a breach; a slap by an officer on a person entirely under his control was degrading treatment.

Removal: extradition and deportation

In Soering v United Kingdom, App no 14038/88, 7 July 1989; Series A no 161 ECtHR · persuasive in Irish courts the Court held that extradition engages the extraditing State’s responsibility where substantial grounds show a real risk of treatment contrary to Article 3 in the requesting country. Extradition to Virginia, given the death-row phenomenon and the applicant’s personal circumstances, would have breached Article 3.

Positive obligations, and Ireland

Article 3 also requires the State to protect people, including from private individuals, and to investigate arguable claims of ill-treatment by State agents.

In O'Keeffe v Ireland, App no 35810/09, 28 January 2014 ECtHR · persuasive in Irish courts the Grand Chamber held that it is an inherent obligation of government to protect children from ill-treatment, especially in primary education, and that the obligation applied in 1973. A State cannot absolve itself by delegating primary education to non-State bodies; it should at least have had effective mechanisms for detecting and reporting abuse. The applicant’s domestic claim had failed in the Supreme Court in O'Keeffe v Hickey [2008] IESC 72; [2009] 2 IR 302 IE · Supreme Court.

Points that come up

Can Article 3 ever be justified?

No. Ireland v United Kingdom held that it prohibits torture and inhuman or degrading treatment in absolute terms, irrespective of the victim’s conduct, and Article 15(2) allows no derogation from it.

What is the difference between torture and inhuman treatment?

Torture is deliberate inhuman treatment causing very serious and cruel suffering, and carries a special stigma. Selmouni v France held that the classification can rise over time.

What did O’Keeffe v Ireland decide?

That the State had a positive obligation, already in 1973, to protect children in national schools from abuse, and could not absolve itself by delegating primary education to non-State bodies.
