ECHR Article 5 — Right to Liberty Lawyer
Article 5 of the European Convention on Human Rights guarantees the right to liberty and security. Our ECHR lawyers challenge unlawful detention in extradition cases — before domestic courts on habeas corpus grounds and at the European Court of Human Rights — with urgent interim measures available where detention is imminent or ongoing.
What Does ECHR Article 5 Protect?
Article 5 of the European Convention on Human Rights guarantees the right to liberty and security of person. It provides that no one shall be deprived of their liberty except in accordance with a procedure prescribed by law and only on grounds the Convention exhaustively defines. Those grounds include conviction by a competent court, lawful arrest on suspicion of a criminal offence, detention of minors, detention on grounds of mental illness, and — critically in the international law context — detention pending extradition or deportation.
Unlike Article 3, Article 5 is a qualified right: deprivation of liberty is permissible in defined circumstances, but the procedural and substantive safeguards surrounding any detention are strictly enforced. Any detention that falls outside the permitted grounds, or that fails to comply with the procedural requirements attached to those grounds, constitutes a violation of Article 5 — and carries with it the right to compensation.
Detention Pending Extradition Under Article 5
Article 5 expressly permits detention of a person against whom action is being taken with a view to deportation or extradition. However, the European Court of Human Rights has established strict conditions that such detention must satisfy to be Convention-compliant.
First, the detention must be lawful under domestic law — it must have a legal basis in national legislation and must comply with that legislation. Second, the detention must not be arbitrary: the extradition proceedings must be conducted with due diligence, without excessive delay, and the detention must remain proportionate throughout. In Chahal v. United Kingdom, the Court held that where extradition proceedings are prolonged by conduct attributable to the authorities — rather than by the complexity of the case or the conduct of the applicant — continued detention may become arbitrary. In Saadi v. United Kingdom, the Court clarified that extradition detention does not require the authorities to show a risk of absconding or reoffending — the sole requirement is that action is being genuinely taken with a view to extradition.
Third, Article 5 requires that the detained person be informed promptly, in a language they understand, of the reasons for arrest. Failure to provide adequate reasons may itself constitute a violation.
The Right to Habeas Corpus
Article 5 guarantees that everyone deprived of their liberty is entitled to take proceedings by which a court determines the lawfulness of the detention speedily and orders release if the detention is unlawful. This habeas corpus guarantee applies in full to extradition detention.
The Court has consistently held that habeas corpus review must be substantive — not merely formal. The reviewing court must assess not only procedural compliance but also whether the grounds for detention remain valid, whether detention has become arbitrary due to delay, and whether continued detention is proportionate. Our ECHR lawyers advise on and pursue habeas corpus proceedings in domestic courts and, where domestic remedies fail, before the European Court of Human Rights.
Excessive Duration of Pre-Extradition Detention
The ECHR has addressed the permissible duration of detention pending extradition in a number of cases. The Convention does not set a fixed maximum period, but the Court scrutinises the overall length of detention against the complexity of the extradition proceedings and any delay attributable to the authorities. Where proceedings are conducted without due diligence — for example, where the requesting state fails to complete documentation in a timely manner or where domestic courts contribute to unnecessary delay — the continued detention will be found to violate Article 5.
Our lawyers monitor the progress of extradition proceedings on behalf of detained clients and take immediate action — including applications for bail and habeas corpus proceedings — when delay becomes unjustified. Where domestic courts fail to act with sufficient speed, an application for interim measures under Rule 39 of the ECHR Rules of Court may be pursued in parallel with an individual application to Strasbourg.
Article 5 and Unlawful Pre-Trial Detention in the Requesting State
Where a client has already been subjected to unlawful detention in the requesting state — for example, before formal extradition proceedings were initiated — Article 5 may provide additional grounds to oppose extradition. Evidence of arbitrary pre-trial detention in the requesting country is relevant to the Article 5 assessment and may also reinforce an Article 3 challenge based on conditions of detention.
How to Challenge Unlawful Detention Under Article 5
An effective Article 5 challenge requires immediate action at every level. Our team provides comprehensive representation:
In domestic proceedings, we apply for bail or release, challenge the legal basis for detention in habeas corpus proceedings, and raise Article 5 arguments before extradition courts. Where detention has been ordered on insufficient grounds or has continued beyond a justified period, we pursue urgent applications to the relevant domestic court.
Where domestic remedies are exhausted or ineffective, we represent clients before the European Court of Human Rights, filing individual applications under Article 34 of the Convention and, where necessary, seeking Rule 39 interim measures to secure immediate release or to halt further proceedings.
If you or someone you know is being held in detention in connection with extradition proceedings and you believe Article 5 has been violated, contact our legal team immediately for an urgent assessment.
