Okay, I will provide you with a detailed description of the decision in the case of *Karslı and Others v. Türkiye*.
**1. Essence of the Decision:**
The European Court of Human Rights (ECtHR) delivered a judgment concerning numerous applications against Türkiye, all related to convictions for membership in the “Fetullahist Terror Organisation/Parallel State Structure” (FETÖ/PDY). These convictions were largely based on the applicants’ use of the encrypted messaging application “ByLock.” The ECtHR found that Türkiye violated Article 7 (no punishment without law) and Article 6 § 1 (right to a fair trial) of the European Convention on Human Rights. The Court determined that the Turkish domestic courts’ approach of automatically equating the use of ByLock with membership in a terrorist organization was a violation of the principle of legality. The Court also identified shortcomings in the procedural framework of the criminal proceedings, particularly the inability of applicants to effectively challenge the ByLock evidence.
**2. Structure and Main Provisions:**
* **Subject Matter:** The judgment addresses the complaints of numerous applicants who were convicted in Türkiye for being members of an armed terrorist organization (FETÖ/PDY). The primary evidence against them was their use of the ByLock application.
* **Joinder of the Applications:** The Court decided to examine all the applications jointly due to their similar subject matter.
* **Alleged Violation of Articles 7 and 6 § 1:** The applicants argued that their convictions violated the principle of no punishment without law (Article 7) and the right to a fair trial (Article 6 § 1).
* **The Court’s Assessment:** The ECtHR referenced its previous judgment in *Yüksel Yalçınkaya v. Türkiye* and its findings in *Demirhan and Others v. Türkiye*, reiterating that the Turkish courts’ approach to ByLock evidence was problematic. The Court found that the mere use of ByLock was treated as conclusive proof of guilt, which contravened the principle of legality. The Court also noted that the applicants’ procedural rights under Article 6 § 1 had been undermined.
* **Other Alleged Violations:** The Court did not find it necessary to examine other complaints raised by the applicants under different articles of the Convention.
* **Application of Article 41:** The Court held that the finding of a violation of Articles 7 and 6 § 1 constituted sufficient just satisfaction for any non-pecuniary damage sustained by the applicants. It also noted that the applicants have the possibility to request the reopening of domestic proceedings.
**3. Main Provisions for Use:**
* The decision reinforces the principle of legality under Article 7, emphasizing that individuals should not be convicted based solely on the use of a particular application without further evidence of criminal intent or activity.
* It highlights the importance of fair trial rights under Article 6 § 1, particularly the right of the defense to effectively challenge evidence presented against them.
* The judgment suggests that Turkish courts should provide appropriate safeguards when dealing with digital evidence, ensuring that defendants have the opportunity to challenge the evidence and that the courts provide adequate reasoning for their decisions.
* The decision is for Ukrainians, as it emphasizes the importance of fair trial rights and the principle of legality, which are essential for ensuring justice and protecting individuals from arbitrary prosecution.
