Chahal v UK [1996] 23 EHRR 413
DEPORTATION – INDIAN CITIZEN – ARTICLE 3 ECHR – RISK OF TORTURE OR DEGRADIG TREATMENT BY FOREIGN STATE
Facts
C, an Indian citizen, was given indefinite leave to remain in the UK after entering illegally. In 1984 he visited India and, due to his associations with the Sikh separatist movement, was detained and tortured by police. Deportation proceedings were initiated after C’s return and his application for political asylum was refused. As the decision to deport concerned national security, he had no right of appeal to an independent tribunal. His case was examined by an advisory panel, who reported to the Secretary of State, but C was allowed no representation and was not told of the evidence against him. C’s application for judicial review failed as, in the absence of evidence of the risk posed to national security, the court was unable to assess whether the Secretary of State’s decision to refuse asylum was irrational.
Issues
The principal issue before the European Court of Human Rights concerned the nature of the prohibition against torture and degrading treatment guaranteed under Art.3 of the European Convention of Human Rights, namely whether this protection was absolute or could be qualified in the interests of national security and the prevention of terrorism.
Decision/Outcome
Art.3 of the ECHR set out an absolute prohibition against “torture or inhumane or degrading treatment”, regardless of the circumstances of the case; the primary consideration in the present case was not national security but rather the possibility that C would be subjected to such treatment in the event of his deportation. As there was substantial evidence of serious human rights abuses by the Indian authorities, and as their assurances of C’s safety were not wholly convincing, C’s deportation would violate Art.3.
The ECtHR also found that here had been violations of Art.5.4 in the refusal to allow C recourse to domestic appeal procedures, as it should be possible to protect confidential information without denying access to the court system.

This case summary accurately reflects the decision in Chahal v United Kingdom (1996) 23 EHRR 413. The core legal principles established by the European Court of Human Rights remain good law: Article 3 ECHR imposes an absolute prohibition on torture and inhuman or degrading treatment or punishment, and this prohibition applies without qualification in expulsion and deportation cases regardless of national security considerations. This position was reaffirmed by the ECtHR Grand Chamber in Saadi v Italy (2009) 49 EHRR 30, which expressly rejected arguments that national security interests could be weighed against the Article 3 risk.
The Article 5(4) findings concerning procedural fairness in the context of confidential national security material were influential in the development of the Special Immigration Appeals Commission (SIAC), established by the Special Immigration Appeals Commission Act 1997, which introduced the Special Advocate procedure to address the deficit identified in this case.
Readers should note that following Brexit, the UK has retained the European Convention on Human Rights in domestic law via the Human Rights Act 1998, which remains in force. There have been ongoing political debates about reform of the Human Rights Act, and the Bill of Rights Bill, which would have introduced a replacement framework, was withdrawn in 2023. The 1998 Act therefore continues to apply. The absolute nature of the Article 3 prohibition in removal cases, as confirmed in Chahal, continues to govern UK courts and the Home Office’s approach to deportation decisions.
