This ASSEDEL commentary offers a doctrinal critique of three separate opinions delivered in the Grand Chamber judgment Yasak v. T\u00fcrkiye (no. 17389\/20, 5 May 2026), which found violations of Articles 3 and 7 ECHR and reversed the Chamber\u2019s judgment. The case concerned the conviction of \u015eaban Yasak for membership of an alleged armed terrorist organization (FET\u00d6\/PDY) based on evidential links to the G\u00fclen movement, and his subsequent detention conditions.<\/p>\n\n\n\n
The commentary examines the reasoning of the dissenting opinions against established case-law. On Article 3, the commentary argues that the Joint Partly Dissenting Opinion on detention conditions employs a disaggregated rather than genuinely cumulative assessment, adopts an administrative-capacity perspective rather than the standpoint of the detained person, misapplies the CPT minimum standard of outdoor exercise as a sufficiency benchmark, and accords excessive weight to the applicant\u2019s voluntary election to remain in the facility and to domestic compliance with Mur\u0161i\u0107 principles. <\/p>\n\n\n\n
On Article 7, the commentary contests the Joint Dissenting Opinion\u2019s thesis that deficiencies in establishing the constituent mental element of a specific-intent offence belong to Article 6 procedural fairness rather than Article 7 legality, demonstrating that nullum crimen sine lege requires an individualized establishment of the mens rea that the offence structurally requires. <\/p>\n\n\n\n
The commentary further addresses Judge N\u00ed Raifeartaigh\u2019s individual dissent, clarifying the jurisprudential basis for recognizing mens rea as an autonomous Article 7 requirement and distinguishing the legality review the Court conducts from the evidentiary reweighing the fourth-instance doctrine forbids. The central doctrinal concern across all three opinions is the substitution of formal compliance with domestic criteria for the substantive assessment the Convention\u2019s case-law requires.<\/p>\n\n\n\n
