FIFTH SECTIONCASE OF KONONENKO AND OTHERS v. UKRAINE(Applications nos. 7340/22 and 9 others –see appended list)      JUDGMENT STRASBOURG12 December 2024 This judgment is final but it may be subject to editorial revision.In the case of Kononenko and Others v. Ukraine,The European Court of Human Rights (Fifth Section), sitting as a Committee composed of: Diana Sârcu, President, Kateřina Šimáčková, Mykola Gnatovskyy, judges,and Viktoriya Maradudina, Acting Deputy Section Registrar,Having deliberated in private on 21 November 2024,Delivers the following judgment, which was adopted on that date:PROCEDURE1. The case originated in applications against Ukraine lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) on the various dates indicated in the appended table.2. The Ukrainian Government (“the Government”) were given notice of the applications.THE FACTS3. The list of applicants and the relevant details of the applications are set out in the appended table.4. The applicants complained of the inadequate conditions of their detention and of the lack of any effective remedy in domestic law. Some applicants also raised other complaints under the provisions of the Convention.THE LAWJOINDER OF THE APPLICATIONS5. Having regard to the similar subject matter of the applications, the Court finds it appropriate to examine them jointly in a single judgment.ALLEGED VIOLATION OF ARTICLES 3 AND 13 OF THE CONVENTION6. The applicants complained principally of the inadequate conditions of their detention and that they had no effective remedy in this connection. They relied on Articles 3 and 13 of the Convention.7. The Court notes that the applicants were kept in detention in poor conditions. The details of the applicants’ detention are indicated in the appended table. The Court refers to the principles established in its case‑law regarding inadequate conditions of detention (see, for instance, Muršić v. Croatia [GC], no. 7334/13, §§ 96‑101, ECHR 2016). It reiterates in particular that a serious lack of space in a prison cell weighs heavily as a factor to be taken into account for the purpose of establishing whether the detention conditions described are “degrading” from the point of view of Article 3 and may disclose a violation, both alone or taken together with other shortcomings (see Muršić, cited above, §§ 122-41, and Ananyev and Others v. Russia, nos. 42525/07 and 60800/08, §§ 149‑59, 10 January 2012).8. In the leading cases of Melnik v. Ukraine (no. 72286/01, 28 March 2006) and Sukachov v. Ukraine (no. 14057/17, 30 January 2020), the Court already found a violation in respect of issues similar to those in the present case.9. Having examined all the material submitted to it, the Court has not found any fact or argument capable of persuading it to reach a different conclusion on the admissibility and merits of these complaints. In particular, the Court observes that, in reply to a prima facie case of inadequate conditions of detention, complained of by the applicants, the Government have failed to provide any primary evidence showing cell floor plans and the actual number of inmates during the specific periods of the applicants’ detention (see Ananyev and Others, cited above, § 123, and, for example, Sparysh and Kutsmand v. Ukraine [Committee], nos. 49709/18 and 49870/18, 12 September 2024). Having regard to its case-law on the subject, the Court considers that in the instant case the applicants’ conditions of detention were inadequate.10. The Court further notes that the applicants did not have at their disposal an effective remedy in respect of these complaints.11. Some applicants submitted other complaints which also raised issues under the Convention, given the relevant well-established case-law of the Court (see appended table). These complaints are not manifestly ill-founded within the meaning of Article 35 § 3 (a) of the Convention, nor are they inadmissible on any other ground.
