FIFTH SECTIONCASE OF PANCHUK v. UKRAINE(Application no. 14607/16)      JUDGMENT STRASBOURG22 July 2021 This judgment is final but it may be subject to editorial revision.In the case of Panchuk v. Ukraine,The European Court of Human Rights (Fifth Section), sitting as a Committee composed of: Stéphanie Mourou-Vikström, President, Jovan Ilievski, Mattias Guyomar, judges,and Viktoriya Maradudina, Acting Deputy Section Registrar,Having deliberated in private on 1 July 2021,Delivers the following judgment, which was adopted on that date:PROCEDURE1.  The case originated in an application against Ukraine lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) on 4 March 2016.2.  The applicant was represented by Ms O. Richko, a lawyer practising in Kharkiv.3.  The Ukrainian Government (“the Government”) were given notice of the application.THE FACTS4.  The applicant’s details and information relevant to the application are set out in the appended table.5.  The applicant complained of the unlawful detention.THE LAWALLEGED VIOLATION OF ARTICLE 5 § 1 of the Convention6.  The applicant complained of the unlawful detention. He relied on Article 5 § 1 of the Convention, which reads as follows:Article 5 § 1“1.  Everyone has the right to liberty and security of person. No one shall be deprived of his liberty save in the following cases and in accordance with a procedure prescribed by law:...(c) the lawful arrest or detention of a person effected for the purpose of bringing him before the competent legal authority on reasonable suspicion of having committed an offence or when it is reasonably considered necessary to prevent his committing an offence or fleeing after having done so; ...”7.  The Court reiterates that Article 5 of the Convention is, together with Articles 2, 3 and 4, in the first rank of the fundamental rights that protect the physical security of the individual, and as such its importance is paramount. Its key purpose is to prevent arbitrary or unjustified deprivations of liberty (see Buzadji v. the Republic of Moldova [GC], no. 23755/07, § 84, ECHR 2016 (extracts), with further references).8.  Where the “lawfulness” of detention is in issue, including the question whether “a procedure prescribed by law” has been followed, the Convention refers essentially to national law and lays down the obligation to conform to the substantive and procedural rules thereof. Compliance with the national law is not, however, sufficient: Article 5 § 1 requires in addition that any deprivation of liberty should be in keeping with the purpose of protecting the individual from arbitrariness (see S., V. and A. v. Denmark [GC], nos. 35553/12, 36678/12 and 36711/12, § 74, 22 October 2018, with further references).9.  In the leading case of Ruslan Yakovenko v. Ukraine (no. 5425/11, §§ 68-70, 4 June 2015) the Court found a violation in respect of issues similar to those in the present case (see the appended table).10.  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 applicant’s detention was not in accordance with Article 5 § 1 of the Convention.11.  It follows that the applicant’s complaint is admissible and discloses a violation of Article 5 § 1 of the Convention.APPLICATION OF ARTICLE 41 OF THE CONVENTION12.  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.”13.  Regard being had to the documents in its possession and to its case‑law (see, in particular, Malyk v. Ukraine, no. 37198/10, 29 January 2015), 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 applicant.14.  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,Declares the application admissible;Holds that this application discloses a breach of Article 5 § 1 of the Convention concerning the unlawful detention;Holds(a)  that the respondent State is to pay the applicant, 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 applicant’s claims for just satisfaction.Done in English, and notified in writing on 22 July 2021, pursuant to Rule 77 §§ 2 and 3 of the Rules of Court. Viktoriya Maradudina Stéphanie Mourou-VikströmActing Deputy Registrar PresidentAPPENDIXApplication raising complaints under Article 5 § 1 of the Convention(unlawful detention)Application no.Date of introductionApplicant’s nameYear of birthPeriod of unlawful detentionSpecific defectsAmount awarded for pecuniary and non-pecuniary damage per applicant(in euros)[1]Amount awarded for costs and expenses per application(in euros)[2]14607/1604/03/2016Yevgen Ivanovych PANCHUK1978 12/09/2015 - 18/09/2015delayed release (Ruslan Yakovenko v. Ukraine, no. 5425/11, §§ 68-70, ECHR 2015)1,800250 [1] Plus any tax that may be chargeable to the applicant.[2] Plus any tax that may be chargeable to the applicant.
