YASAK / TURKEY JUDGMENT – LEGAL ASSESSMENT REPORT
The Grand Chamber judgment of the ECtHR dated 5 May 2026 in Yasak v. Turkey constitutes a highly significant turning point for criminal proceedings conducted after 15 July.
The Court found that the most fundamental principle of criminal law was violated in the applicant’s conviction for membership in an armed terrorist organization: a person cannot be punished without their personal culpability and criminal intent being concretely established.
