FIFTH SECTIONCASE OF BARTKOVA AND VORONIN v. UKRAINE(Applications nos. 24178/14 and 67581/17)      JUDGMENT STRASBOURG10 February 2022 This judgment is final but it may be subject to editorial revision.In the case of Bartkova and Voronin v. Ukraine,The European Court of Human Rights (Fifth Section), sitting as a Committee composed of: Lətif Hüseynov, President, Lado Chanturia, Arnfinn Bårdsen, judges,and Viktoriya Maradudina, Acting Deputy Section Registrar,Having deliberated in private on 20 January 2022,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 lack of relevant and sufficient reasons for detention. They 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 ARTICLE 5 § 3 of the Convention6.  The applicants complained principally of the lack of relevant and sufficient reasons for detention. They relied, expressly or in substance, on Article 5 § 3 of the Convention, which reads as follows:Article 5 § 3“3.  Everyone arrested or detained in accordance with the provisions of paragraph 1 (c) of this Article shall be brought promptly before a judge or other officer authorised by law to exercise judicial power and shall be entitled to trial within a reasonable time or to release pending trial. Release may be conditioned by guarantees to appear for trial.”7.  The Court reiterates that, according to its established case-law under Article 5 § 3 of the Convention, the persistence of a reasonable suspicion that the person arrested has committed an offence is a condition sine qua non for the lawfulness of the continued detention, but after a certain lapse of time it no longer suffices. In such cases, the Court must establish whether the other grounds given by the judicial authorities continued to justify the deprivation of liberty. Where such grounds were “relevant” and “sufficient”, the Court must also ascertain whether the competent national authorities displayed “special diligence” in the conduct of the proceedings. The Court has also held that justification for any period of detention, no matter how short, must be convincingly demonstrated by the authorities. When deciding whether a person should be released or detained, the authorities are obliged to consider alternative measures for ensuring this person’s appearance at trial. The requirement for the judicial officer to give “relevant” and “sufficient” reasons for the detention – in addition to the persistence of reasonable suspicion – applies already at the time of the first decision ordering detention on remand, that is to say “promptly” after the arrest (see, among other authorities, Buzadji v. the Republic of Moldova [GC], no. 23755/07, §§ 87 and 102, 5 July 2016).8.  In the leading case of Korban v. Ukraine, no. 26744/16, §§ 158-81, 4 July 2019, 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. Having regard to its case-law on the subject, the Court considers that in the instant case the domestic courts failed to provide relevant and sufficient reasons for the applicants’ pre-trial detention.10.  These complaints are therefore admissible and disclose a breach of Article 5 § 3 of the Convention.REMAINING COMPLAINTS11.  The applicants also raised other complaints under various Articles of the Convention.12.  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, they 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.13.  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.  Article 41 of the Convention provides:“If the Court finds that there has been a violation of the Convention or the Protocols thereto, and if the internal law of the High Contracting Party concerned allows only partial reparation to be made, the Court shall, if necessary, afford just satisfaction to the injured party.”15.  Regard being had to the documents in its possession and to its case‑law (see, in particular, Ara Harutyunyan v. Armenia , no. 629/11, § 66, 20 October 2016), the Court considers it reasonable to award the sums indicated in the appended table and it rejects any additional claims for just satisfaction raised by the applicants.16.  The Court considers it appropriate that the default interest rate should be based on the marginal lending rate of the European Central Bank, to which should be added three percentage points.FOR THESE REASONS, THE COURT, UNANIMOUSLY,Decides to join the applications;Declares the complaints concerning the lack of relevant and sufficient reasons for detention admissible and the remainder of the applications inadmissible;Holds that these complaints disclose a breach of Article 5 § 3 of the Convention concerning the lack of relevant and sufficient reasons for detention; Holds(a)  that the respondent State is to pay the applicants, within three months, the amounts indicated in the appended table, to be converted into the currency of the respondent State at the rate applicable at the date of settlement;(b)  that from the expiry of the above-mentioned three months until settlement simple interest shall be payable on the above amounts at a rate equal to the marginal lending rate of the European Central Bank during the default period plus three percentage points;Dismisses the remainder of the applicants’ claims for just satisfaction.Done in English, and notified in writing on 10 February 2022, pursuant to Rule 77 §§ 2 and 3 of the Rules of Court.  Viktoriya Maradudina Lətif Hüseynov Acting Deputy Registrar President   APPENDIXList of applications raising complaints under Article 5 § 3 of the Convention(lack of relevant and sufficient reasons for detention)No.Application no.Date of introductionApplicant’s nameYear of birthRepresentative’s name and locationPeriod of detentionCourt which issued detention order/ examined appealSpecific defectsAmount awarded for non-pecuniary damage per applicant(in euros)[1]Amount awarded for costs and expenses per application(in euros)[2]   24178/1413/03/2014InnaYevgenivnaBARTKOVA1988 Danilevych Tetyana MykolayivnaVinnytsyafrom 22/01/2014 to 07/09/2015Vinnytsya City Courtfragility of the reasons employed by the courts, use of assumptions, in the absence of any evidentiary basis, of the risks of absconding or obstructing justice2,000250   67581/1730/08/2017LevYuriyovychVORONIN1963 Ignatov Oleksandr AnatoliyovychDnipro01/08/2017-27/10/2017Kyiv-Sviatoshynskyy District Courtfailure to assess the applicant’s personal situation reducing the risks of re-offending, colluding or absconding, failure to examine the possibility of applying other measures of restraint, fragility of the reasons employed by the courts2,000- [1] Plus any tax that may be chargeable to the applicants.[2] Plus any tax that may be chargeable to the applicants.
