1. Case Title

A.S. v. Türkiye – ECtHR (Application No. 28241/21)

2. Respondent State

Türkiye

3. Nature of the Case

The applicant was detained due to alleged presence and interaction on an encrypted digital application. He argues that such digital behaviour lacks any individualised suspicion required by Article 5 §1(c).

4. Theme of the Case

The case concerns digital expression, criminalisation of messaging-app use, and arbitrary detention arising from digital interaction traces. It raises fundamental questions about privacy, digital autonomy and the limits of digital evidence.

5. Impact

The case could affirm that digital presence, app usage or participation in encrypted communication channels cannot justify detention without corroborating criminal conduct. It will strengthen European protection standards for digital privacy and online civic space.
