FIFTH SECTION      CASE OF ISAYEV AND OTHERS v. UKRAINE (Applications nos. 1292/14 and 16 others -see appended list)             JUDGMENT    STRASBOURG 6 December 2018   This judgment is final but it may be subject to editorial revision.In the case of Isayev and Others v. Ukraine,The European Court of Human Rights (Fifth Section), sitting as a Committee composed of: Síofra O’Leary, President, Mārtiņš Mits, Lado Chanturia, judges,and Liv Tigerstedt, Acting Deputy Section Registrar,Having deliberated in private on 15 November 2018,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 applications were communicated to the Ukrainian Government (“the Government”).THE FACTS3. The list of applicants and the relevant details of the applications are set out in the appended table.4. The applicants complained that they were deprived of an opportunity to comment on the appeals lodged by the defendants in their cases. Some applicants also raised other complaints under the provisions of the Convention.THE LAWI. JOINDER 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.II. THE LOCUS STANDI OF MS OLENA VASYLIVNA SIROZHENKO6. As concerns the complaints raised by the applicant in application no. 42952/14, the Court notes that the applicant died on 27 March 2015, while the case was pending before the Court. The applicant’s wife, Ms Olena Vasylivna Sirozhenko, has requested to pursue the application on her husband’s behalf. As the request is in line with its case-law, the Court sees no reason to refuse it (see, among other authorities, Petr Korolev v. Russia, no. 38112/04, §§ 43-45, 21 October 2010; Sergey Denisov and Others v. Russia, nos. 1985/05 and 4 others, §§ 73-75, 19 April 2016; Benyaminson v. Ukraine, no. 31585/02, § 83, 26 July 2007; and Horváthová v. Slovakia, no. 74456/01, §§ 25-27, 17 May 2005). However, reference will still be made to the applicant throughout the present text.III. ALLEGED VIOLATION OF ARTICLE 6 § 1 OF THE CONVENTION7. The applicants complained that the principle of equality of arms had been breached on account of the domestic courts’ failure to serve appeals on them or otherwise inform them of the appeals lodged in their cases. They relied on Article 6 § 1 of the Convention, which reads as follows:Article 6 § 1“In the determination of his civil rights and obligations ... everyone is entitled to a ... hearing within a reasonable time by [a] ... tribunal ...”8. The Court reiterates that the general concept of a fair trial, encompassing the fundamental principle that proceedings should be adversarial (see Ruiz-Mateos v. Spain, 23 June 1993, § 63, Series A no. 262), requires that the person against whom proceedings have been initiated should be informed of this fact (see Dilipak and Karakaya v. Turkey, nos. 7942/05 and 24838/05, § 77, 4 March 2014). The principle of equality of arms requires that each party should be afforded a reasonable opportunity to present his or her case under conditions that do not place him or her at a substantial disadvantage vis-à-vis his or her opponent (see Avotiņš v. Latvia [GC], no. 17502/07, § 119, ECHR 2016, and Dombo Beheer B.V. v. the Netherlands, 27 October 1993, § 33, Series A no. 274). Each party must be given the opportunity to have knowledge of and comment on the observations filed or evidence adduced by the other party, including the other party’s appeal. What is at stake is the litigants’ confidence in the workings of justice, which is based on, inter alia, the knowledge that they have had the opportunity to express their views on every document in the file (see Beer v. Austria, no. 30428/96, §§ 17-18, 6 February 2001).9. It may, therefore, be incumbent on the domestic courts to ascertain that their summonses or other documents have reached the parties sufficiently in advance and, where appropriate, record their findings in the text of the judgment (see Gankin and Others v. Russia, nos. 2430/06 et al, § 36, 31 May 2016). If court documents are not duly served on a litigant, then he or she might be prevented from defending him or herself in the proceedings (see Zavodnik v. Slovenia, no. 53723/13, § 70, 21 May 2015, with further references).10. In the leading case of Lazarenko and Others v. Ukraine, (nos. 70329/12 and 5 others, 27 June 2017), the Court already found a violation in respect of issues similar to those in the present case.11. Having examined all the material submitted to it and lacking any evidence of proper notification of the applicants, 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 finds that by proceeding to consider the appeals lodged in the applicants’ cases without attempting to ascertain whether they were served on the applicants or whether the applicants were informed of the appeals by any other means, the domestic courts deprived the applicants of the opportunity to comment on the appeals lodged in their cases and fell short of their obligation to respect the principle of equality of arms enshrined in Article 6 of the Convention.12. OTHER ALLEGED VIOLATIONS UNDER WELL-ESTABLISHED CASE-LAW13. The applicants in applications nos. 30523/14, 29820/15, 16469/16 and 66870/17 submitted other complaints under the articles of the Convention and its Protocols which also raised issues, 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.

Outcome for Article 6: violation
