On 25 August 2026 the Grand Chamber of the European Court of Human Rights issued a judgment in Kavala v. Türkiye (No. 2) finding multiple breaches of the European Convention on Human Rights in relation to Osman Kavala’s prolonged detention, trial and conviction. The Court concluded that Türkiye must secure Kavala’s release “at the earliest possible date” and take steps to eliminate the consequences of his conviction. The judgment examined the whole sequence of post‑2019 events — including renewed criminal proceedings that produced an aggravated life sentence — and found violations of rights including liberty, fair trial and freedoms of expression and assembly, as well as misuse of restrictions for improper purposes.

Why this matters: The Grand Chamber ruling is legally significant for several reasons. First, it reaffirms that domestic criminal proceedings and sentences cannot be used to nullify earlier binding judgments of the Court or to perpetuate deprivation of liberty after an international finding has been made. Second, the judgment invokes Article 46 enforcement obligations (execution of the Court’s judgments), requiring not only individual relief for Kavala but also remedial measures to address systemic problems in domestic procedures. That increases pressure on national authorities and the Council of Europe’s Committee of Ministers, which supervises execution of ECHR judgments, to monitor compliance and consider follow‑up measures.
Background in plain language: Osman Kavala, a long‑standing figure in Turkish civil society litigation, was the subject of an earlier ECHR ruling; subsequent domestic prosecutions and a conviction to aggravated life imprisonment were examined by the Grand Chamber as a whole. The Court’s order to secure immediate release and to eliminate the conviction’s consequences does not itself overturn a national conviction directly; rather, it creates binding international legal obligations that require domestic action — for example, reopening or revisiting domestic remedies, annulment or other legal steps that effectively remove the sentence’s legal consequences — and it empowers the Committee of Ministers to supervise implementation.
