FIFTH SECTIONCASE OF KALIMOV AND OTHERS v. UKRAINE(Applications nos. 26875/23 and 10 others –see appended list)      JUDGMENT STRASBOURG24 October 2024 This judgment is final but it may be subject to editorial revision.In the case of Kalimov and Others v. Ukraine,The European Court of Human Rights (Fifth Section), sitting as a Committee composed of: Kateřina Šimáčková, President, Mykola Gnatovskyy, Artūrs Kučs, judges,and Viktoriya Maradudina, Acting Deputy Section Registrar,Having deliberated in private on 3 October 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.THE LAWJOINDER OF THE APPLICATIONS4. 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 CONVENTION5. 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.6. 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).7. 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.8. The Court further observes in the present case that, in reply to a prima facie complaint of inadequate conditions of detention, no primary evidence showing cell floor plans and the actual number of inmates during the entire period of the applicants’ detention have been provided by the Government (see Ananyev and Others v. Russia, cited above, § 123, and, for example, Sparysh and Kutsmand v. Ukraine [Committee], nos. 49709/18 and 49870/18, 12 September 2024).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. Having regard to its case-law on the subject, the Court considers that in the instant case the applicants’ conditions of detention during the periods indicated in the appended table 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. In applications nos. 577/24 and 579/24, the applicants also raised other complaints under Article 3 of the Convention.13. The Court has examined these complaints and considers that, in the light of all the material in its possession and in so far as the matters complained of are within its competence, these complaints either do not meet the admissibility criteria set out in Articles 34 and 35 of the Convention or do not disclose any appearance of a violation of the rights and freedoms enshrined in the Convention or the Protocols thereto.It follows that this part of the applications must be rejected in accordance with Article 35 § 4 of the Convention.APPLICATION OF ARTICLE 41 OF THE CONVENTION14. Regard being had to the documents in its possession and to its case‑law (see, in particular, Sukachov, cited above, §§ 165 and 167), the Court considers it reasonable to award the sums indicated in the appended table.

Outcome for Article 3: violation
