## Facts

- Widespread violence in Northern Ireland led the United Kingdom to adopt emergency security measures, including internment without trial of suspected terrorists.
- The Republic of Ireland filed an inter-State application alleging systemic violations of the European Convention on Human Rights arising from detention, internment, and interrogation practices.
- A group of detainees were subjected, in combination, to five interrogation methods: wall-standing (stress position), hooding, continuous loud noise, sleep deprivation, and reduced food and drink.
- The five techniques were treated as an interrogation policy rather than isolated misconduct and were later disavowed by the United Kingdom, which stated they would not be used in the future.
- Ireland alleged violations of Article 3 (torture; inhuman or degrading treatment), Article 5 (liberty and security), Article 6 (fair trial), and Article 14 (non-discrimination), and contested the scope of the United Kingdom’s Article 15 derogation during a public emergency.

## Issues

1. Whether the combined use of the five techniques violated Article 3, and whether the conduct constituted “torture” or “inhuman or degrading treatment.”
2. Whether internment and related emergency detention measures violated Articles 5 and 6, and to what extent any departures were justified by an Article 15 derogation as “strictly required by the exigencies of the situation.”
3. Whether the challenged practices reflected attributable State policy sufficient to establish responsibility in an inter-State proceeding.

## Decision

- The Court held that the five techniques, used in combination, violated Article 3 as inhuman and degrading treatment.
- The Court held that the five techniques did not constitute torture on the facts and under the severity threshold applied at the time.
- The Court accepted that Northern Ireland faced a public emergency capable of engaging Article 15.
- The Court reached a mixed result under Articles 5 and 6, accepting that certain departures could be permitted under Article 15 while finding other aspects incompatible with Convention requirements.
- The Court treated the interrogation methods as attributable to the State because they were authorized and implemented as an official practice during the relevant period.

## Legal Principles

- Article 3 is absolute: no derogation is permitted, even during a public emergency.
- Classification under Article 3 turns on severity and purpose: torture is deliberate inhuman treatment causing very serious and cruel suffering; inhuman treatment causes intense physical or mental suffering; degrading treatment humiliates or debases by inducing fear, anguish, or inferiority.
- Combined interrogation methods can breach Article 3 even if individual techniques are evaluated in context; official authorization and policy use support State responsibility.
- Under Article 15, a State may derogate from certain obligations only to the extent “strictly required by the exigencies of the situation,” subject to judicial scrutiny despite a margin of appreciation.
- A State’s later repudiation of unlawful practices does not erase responsibility for violations committed during the relevant period.

## Conclusion

The Court found that the United Kingdom’s coordinated use of the five techniques in Northern Ireland breached Article 3 as inhuman and degrading treatment but not torture, reaffirmed the non-derogable nature of Article 3, and evaluated emergency detention measures under Article 15’s strict-necessity standard, producing a mixed outcome under Articles 5 and 6.
