NAVALNYY v. RUSSIA (No. 4) - 4743/21 (Article 5 - Right to liberty and security : Third Section) [2026] ECHR 19 (03 February 2026)

Executive summary

The European Court of Human Rights held that Russia unlawfully detained Aleksey Navalnyy after activating his suspended sentence based on the 2014 conviction, and also unlawfully detained him pending the activation proceedings. It found that the earlier criminal case had been previously condemned by the Court as a flagrant denial of justice and that the domestic courts used an unforeseeable, legally expansive application of Russian law; the judgment also addressed Article 2, Article 3, and Article 34 issues arising from the same detention episode.

Key points

• Applicant: Aleksey Anatolyevich Navalnyy; respondent: Russian Federation; applications nos. 4743/21 and 37083/21.
• Article 5 § 1: detention after activation of the suspended sentence was unlawful because it was causally tied to the 2014 conviction, which had already been found to violate Articles 6 and 7.
• Article 5 § 1: pending the activation proceedings, domestic courts applied legal provisions by “analogy” contrary to their wording, breaching legal certainty.
• Article 2 (substantive): the Court found a real and immediate risk to the applicant’s life and held that authorities failed to carry out an adequate risk assessment or address his complaints.
• Article 3 (substantive): the applicant was subjected to combined ill-treatment in detention, including 39 days of sleep deprivation and shaving of his hair without legal basis.
• Article 34: Russia’s failure to comply with the Rule 39 interim measure to immediately release him hindered the right of individual application.

Why it matters

The judgment reinforces that detention measures built on previously condemned or unforeseeably applied criminal convictions can generate direct Convention exposure, including where the state uses probation or sentence-activation mechanisms. For sanctions and sovereign-risk audiences, it adds to the record of judicial findings against Russia involving politically sensitive detention, non-compliance with interim measures, and treatment raising Article 2/3 concerns.

Implications

Compliance and litigation teams should treat Russian detention, probation-activation, and criminal-enforcement actions against opposition figures as higher-risk where they rely on prior convictions already found Convention-defective or on expansive interpretations of domestic law. The judgment strengthens arguments for non-recognition of the legality of such detention measures, supports human-rights-based escalation in sovereign-risk assessments, and may be cited to challenge state conduct in future enforcement or asset-risk analyses.
