Having regard to:
the applications (nos. 42126/15 and 42127/15) against Georgia and Russia lodged with the Court under Article 34 of the Convention for the Protection of Human Rights and Fundamental Freedoms (“the Convention”) on 21 August 2015 by two Georgian nationals, Mr O.J. (“the first applicant”) and Mr J.O. (“the second applicant”; together “the applicants”), who were born in 1977 and 1964 respectively;
the decision not to have the applicants’ names disclosed;
the decision to give notice of the applications to the Georgian Government, represented by their Agent, Mr B. Dzamashvili, and to the Russian Government, represented successively by Mr G. Matyushkin, Mr M. Galperin and Mr M. Vinogradov, Representatives of the Russian Federation at the European Court of Human Rights;
the parties’ observations;
the decision to uphold the Georgian Government’s objection to examination of the applications by a Committee;
Having deliberated in private on 28 November 2023,
Delivers the following judgment, which was adopted on that date:
INTRODUCTION
1. The applications concern the applicants’ complaints that they had been ill-treated during their arrest and subsequent unlawful detention in the Autonomous Republic of Abkhazia, Georgia, (hereinafter “Abkhazia”) and that they had not received a fair hearing in the proceedings before the de facto Supreme Court of Abkhazia (“the de facto SCA”), which had sentenced them to imprisonment for “endangering the constitutional order of Abkhazia through the commission of espionage”. The Court notes that the term “Abkhazia” refers to the region in Georgia which is currently outside the de facto control of the Georgian Government. The applications further concern the absence of an effective remedy in respect of their complaints. 2. On 16 March 2022 the Committee of Ministers of the Council of Europe, in the context of a procedure launched under Article 8 of the Statute of the Council of Europe, adopted Resolution CM/Res(2022)2, by which the Russian Federation ceased to be a member of the Council of Europe as from 16 March 2022. 3. On 22 March 2022 the Court, sitting in plenary session in accordance with Rule 20 § 1 of the Rules of Court, adopted the “Resolution of the European Court of Human Rights on the consequences of the cessation of membership of the Russian Federation to the Council of Europe in light of Article 58 of the European Convention on Human Rights”. It stated that the Russian Federation would cease to be a High Contracting Party to the Convention on 16 September 2022. 4. On 5 September 2022 the plenary Court took formal notice of the fact that the office of judge in respect of the Russian Federation would cease to exist after 16 September 2022. This, as a consequence, entailed that there was no longer a valid list of ad hoc judges who would be eligible to take part in the consideration of cases where the Russian Federation was the respondent State. 5. By a letter of 8 November 2022, the Russian Government were informed, inter alia, that the Court intended to appoint one of the sitting judges of the Court to act as an ad hoc judge for the examination of applications against that State which the Court remained competent to deal with (applying by analogy Rule 29 § 2). The Russian Government were invited to comment on that arrangement by 22 November 2022 but they did not submit any comments. 6. Accordingly, in the present case the President of the Chamber decided to appoint an ad hoc judge from among the members of the composition, applying by analogy Rule 29 § 2 (b). THE FACTS        detention and sentencing of the applicants

7. The applicants were represented by Mr D. Khachidze, a lawyer practising in Tbilisi. 8. The facts of the case may be summarised as follows on the basis of the submissions provided by the applicants. 9. The Georgian Government emphasised their inability to obtain information regarding the factual circumstances and stated that they did not challenge the applicants’ assertions. The Russian Government did not contest the facts as described by the applicants but stated that no evidence of the involvement of Russian agents in the events complained of had been provided. 10. Both applicants were arrested on 15 March 2012 in the second applicant’s house in Tagiloni, a village in Gali Region, Abkhazia, by a special-forces team of the de facto Abkhaz Security Services (“the de facto security services”), who found two hand grenades and a hunting knife in the house after they had searched it. 11. Criminal proceedings for espionage were brought against the applicants and the de facto SCA subsequently delivered a judgment on 16 April 2013 finding both of them guilty as charged (see paragraph 1 above) and sentencing the first applicant to eleven years and six months’ imprisonment and the second applicant to thirteen years’ imprisonment. Specifically, the de facto SCA found that in early 2011 the applicants, acting under the instructions of the Department of Military Intelligence of the Ministry of Defence of Georgia (“the DMI”), had recruited D.K. – a soldier from the Russian military unit of border guards based at Tagiloni village – as an informant for the DMI and had themselves served as intermediaries for transmitting information to the Georgian authorities. 12. According to the applicants, they had been ill-treated by the de facto security services at the time of their arrest, as well as over several days thereafter while being questioned about their ties with the DMI and the Russian informant mentioned above. Both applicants had allegedly been beaten while handcuffed to chairs, as well as subjected to waterboarding. In addition, the first applicant had had his teeth loosened – but not removed – by means of forceps used for tooth extraction and had been threatened with rape and told that footage of it would be uploaded on the Internet. The second applicant had had a rope tied around his neck in a simulation of strangulation. 13. The applicants were assigned lawyers on 19 March 2012 who advised them to confess in order to stop the beatings. Subsequently, both applicants declared that they had had ties to the DMI (see paragraph 11 above). On 23 March 2012 both applicants were charged with espionage (see paragraph 1 above) and the second applicant also with unlawful possession of ammunitions and a cold weapon. 14. According to the applicants, even though after their “confessions” the beatings had become less frequent, they had continued to be ill-treated while being questioned twice a week by the de facto security services and by Russian military staff working for the Russian Federal Security Service. 15. The applicants spent the first six months of their detention at the de facto security services’ premises in Sukhumi and the following three months at the temporary detention facilities of the de facto Abkhaz Ministry of the Interior in Sukhumi. They were then transferred to Dranda Prison where their trial took place. 16. It appears that at some point in time D.K. (see paragraph 11 above) was arrested and charged with high treason in Russia. During the criminal proceedings against him, he allegedly confessed that he had served as an informant for the DMI and incriminated the applicants. 17. According to the applicants, although they had told the de facto SCA that their confessions had been extracted under torture, the de facto SCA had relied on those statements as part of the evidence used to convict them. 18. An appeal against the judgment was in principle possible within a ten‑day period, as indicated in the de facto SCA’s judgment; however, considering that an appeal would be futile, the applicants did not pursue it. 19. According to the applicants, the Georgian authorities had been informed of their detention and ill-treatment from the early days after their arrest. 20. The applicants’ family members repeatedly reached out to officials at the Ministry of Defence, who repeatedly assured them orally that all measures had been taken to secure the applicants’ release. In addition, on 6 February 2015 relatives of the applicants wrote a letter addressed to the President of Georgia, the Prime Minister and the State Minister for Reconciliation and Civic Equality (“the State Minister”). The information was subsequently passed on to the Chief Public Prosecutor, the Ministry of Foreign Affairs and the DMI. 21. On 20 February 2015 the first applicant’s wife received a reply from the State Minister’s office informing her that consultations concerning the applicants were underway and that she would be informed of any developments. Later in 2015 the first applicant’s sister wrote a letter to the State Minister. On 4 August 2015 the State Minister’s office replied, informing her that there were some “positive indications” concerning the applicants and again assuring her that the family would be informed in due course of further developments. 22. Both applicants were released on 10 March 2016 following interventions by the Georgian authorities and, in particular, negotiations they had started with the de facto Abkhaz authorities in May 2015 (see paragraph 36 below). Relations between the respondent States and the de facto Abkhaz authorities   Relations between the Russian Federation and the de facto Abkhaz authorities     The applicants’ submissions

23. The applicants submitted that the Russian Federation had been exercising effective control over the territory of Abkhazia through its military forces since 1993. The Georgian Government’s submissions
24. The Georgian Government submitted that the de facto Abkhaz authorities had had Russia’s continued and decisive support to the extent that they had survived and continued to survive only by virtue of Russian military, economic, financial and political support. In particular, Abkhazia had been absorbed into Russia’s military, security, political, economic, social and humanitarian sectors. This had been demonstrated more specifically by the application of the Law on Citizenship of the Russian Federation; Russia’s direct involvement in the de facto Abkhaz administration, including key positions within the de facto defence, law enforcement and security authorities; Russia’s military aggression against Georgia; the recognition by Russia of Abkhazia as an independent State; the agreements signed by Russia with Abkhazia in violation of international law and the sovereignty of Georgia; Russia’s continued occupation of Abkhazia; Russia’s control of the different territory “borders” within Georgia; the large number of Russian troops and their military bases; and Russia’s essential financial support of the Abkhaz administration and their investment in infrastructure projects, including a gas pipeline. The Russian Government’s submissions
25. The Russian Government stated that the Russian troops participating in peacekeeping operations in Georgia had withdrawn from the temporarily occupied regions of Georgia to the security zones at the borders of Abkhazia (and South Ossetia) by 22 August 2008. They had completed their planned withdrawal to Russia by 1 September 2008. On 9 October 2008 the peacekeepers of the Russian Federation had also been withdrawn from the above-mentioned security zones, whereas the events of the present case had allegedly occurred in 2012. 26. The Russian Government also emphasised that the applicants had been apprehended by officers of the “Abkhaz security services” who were representatives of a “government body which was not subordinate to the Russian Federation”. Furthermore, the applicants had been kept in the Abkhaz security services’ premises in Sukhumi, which was a place “not belonging to the competence of the Russian Federation”. Relations between Georgia and the de facto Abkhaz authorities     The applicants’ submissions

27. The applicants did not make specific submissions on this matter. They pointed out more generally that, although Georgia had not been able to exercise control over Abkhaz territory since 1993, the government of Georgia had not made a reservation regarding the application of the Convention in that territory. The Russian Government’s submissions
28. The Russian Government did not make specific submissions on this matter. The Georgian Government’s submissions   Measures for resolving the conflict and observing human rights in Abkhazia

29. The Georgian Government submitted that Georgia had been making all possible efforts to resolve the conflict and ensure respect for human rights in Abkhazia. 30. Since 1992 Georgia had been keeping the international community informed of the situation in Abkhazia and had been requesting, both in bilateral and multilateral contexts, support for the peaceful resolution of the conflict. The government of Georgia had spared no effort to address the issues of ending the occupation of the territory, the implementation of the Ceasefire Agreement of 12 August 2008 mediated by the European Union (for more information about the ceasefire agreement, see Georgia v. Russia (II) [GC], no. 38263/08, § 153, 21 January 2021) and the humanitarian situation on the ground. Particular attention had been paid to the implementation of reconciliation and engagement policies as well as to confidence-building measures. 31. They further submitted that, following the 2008 conflict, the Geneva International Discussions (“the GID”)[1] had been the sole forum for exchange between Georgia and Russia which was aimed at addressing the consequences of the August 2008 military conflict, in particular in the occupied regions in Georgia. The Georgian representatives at the GID had continually raised the subject of the human rights situation in Abkhazia, specifically as regards, but not limited to, kidnappings, unlawful detention and lack of access by people to their property located in Abkhaz territory, and had deplored that the territory had remained inaccessible to the international community. During the period in question in the present applications, namely between 2012 and 2015, the Georgian authorities had registered 996 cases of human rights breaches in Abkhazia, which included but were not limited to abductions, arbitrary detentions, ill-treatment, restrictions on freedom of movement and verbal and physical abuse. 32. On 7 March 2013 the Georgian Parliament had adopted a Resolution on Basic Directions of Georgia’s Foreign Policy, which reaffirmed Georgia’s territorial integrity and its policy of non-recognition of Abkhazia (and South Ossetia). Measures in respect of the protection of human rights of people living near the occupation line had been part of the Action Plan of the Government of Georgia on the Protection of Human Rights 2014-2016. The Ministry for Foreign Affairs had also produced quarterly reports on the human rights situation in Georgia. Those reports had identified problems and had systematically appealed to the international community, including States as well as international, intergovernmental and non-governmental organisations (NGOs), to continue to call on the Russian Federation to bear responsibility for human rights violations in the occupied regions and to stop placing barbed wire fences and other obstacles (and remove those already placed) along the occupation line. The State Minister’s office had systematically collected and processed material on human rights breaches in Abkhazia and prepared related reports for the GID, monitored elections in Abkhazia and daily Abkhaz media and cooperated with international and local NGOs working in Abkhazia. 33. The Georgian Government further submitted that Georgia had also been committed to creating favourable conditions for a long-term reconciliation process which was aimed at promoting interaction among the divided populations of Georgia, who had been separated by occupation lines, and the reintegration of Abkhazians. The State Minister’s office had been pursuing policies promoting civil society development in Abkhazia. As part of the State’s strategy in the occupied territories, residents of those territories had been able to benefit from State-subsidised medical treatment in Georgia according to their needs. Georgia had also been sending vaccines, life-saving medication and some medical equipment to the Abkhaz territory. 34. The Georgian authorities had also pursued efforts towards ensuring the safe, unconditional and dignified return to Abkhazia of forcibly displaced people as well as their descendants. 35. Georgia’s policy as regards Russia in the period between 2012 and 2016 had been aimed at de-escalating tensions and creating an environment conducive to genuine dialogue. While this had led to the partial restoration of economic and humanitarian ties with Russia, it had not translated into finding political solutions to the problem. Individual measures taken by Georgia to ensure the applicants’ rights under the Convention
36. The Georgian Government pointed out that on 10 March 2016 the applicants had been released from their unlawful detention as a result of the Georgian authorities’ lengthy, complex and intensive efforts, which had lasted ten months. The Georgian authorities had been providing the applicants with psychological, social, financial and legal assistance since their release. RELEVANT LEGAL FRAMEWORK AND PRACTICE
37. The parties did not provide any relevant information. THE LAW
        PRELIMINARY issues
38. In view of the fact that the Russian Federation ceased to be a Party to the Convention on 16 September 2022 (see paragraph 2 above), the Court decides that it has jurisdiction to deal with the applicants’ complaints in so far as they relate to facts that took place before that date (see Fedotova and Others v. Russia [GC], nos. 40792/10 and 2 others, §§ 68-73, 17 January 2023, and Ukraine and the Netherlands v. Russia (dec.) [GC], nos. 8019/16 and 2 others, 25 January 2023). JOINDER OF THE APPLICATIONS
39. Having regard to the similar subject matter of the applications, the Court finds it appropriate to examine them jointly in a single judgment (Rule 42 § 1). ADMISSIBILITY ISSUES   The parties’ submissions     The Russian Government

40. The Russian Government raised a number of objections to the admissibility of the applications. In the first place, they stated that the applicants had failed to properly apply to the Court because they had authorised their representative to act on their behalf, not in the application form itself, but in a separate authority form and the application before the Court had been signed only by their representative but not by the applicants themselves. Furthermore, the applicants’ signatures on their passports differed from their signatures on the authority forms, which raised doubts as to whether the applicants had indeed authorised their legal representative to act on their behalf in the proceedings before the Court. 41. In addition, they submitted that the applicants had failed to comply with the six-month time-limit, as they had not justified the delay of about four years in turning to the Court, calculated from the time of the facts complained of. The Russian Government referred explicitly to the general applicable principle under the Convention concerning the absence of effective remedies (see paragraph 47 below), yet did not specifically state that there had not been effective remedies at the applicants’ disposal. 42. Lastly, the Russian Government asserted that the applications were incompatible with the Convention ratione loci. Their submissions on that point can be found in paragraph 26 above. The Georgian Government
43. The Georgian Government did not make any submissions as regards admissibility. The applicants
44. The applicants stated that they had signed the authority forms in 2015 while they had been detained in Abkhazia. Their passports, however, had been issued in 2009 and 1994 respectively. The long period which had elapsed between the issuance of their passports and their signing of the authority forms explained the difference in signatures. They confirmed that they had authorised their representative to act on their behalf in the proceedings before the Court. Without specifying further, they added that meetings between themselves and their relatives or their lawyer in Abkhaz territory had depended on the will of the local de facto administration. Lastly, they stated that Russia had been exercising effective control over the territory of Abkhazia since 1993 and that Russian officers had been directly involved in their ill-treatment during interrogation. The Court’s assessment     The applicants’ signatures on the documents in their applications to the Court

45. The Court accepts that, in view of having been detained by the de facto authorities in Abkhazia at the time of lodging their applications with the Court, the applicants validly authorised their representative to act on their behalf in the proceedings before the Court. In particular, given that their access to family members and their lawyer depended on the will of the de facto authorities, as asserted by them and not disputed by the two respondent Governments, the Court accepts that the applicants’ authorising their representative in an authority form separate from the application form itself does not raise an issue in terms of compliance with the procedure for applying to the Court. The Court further notes that the matter raised by the Russian Government is not one of the grounds for inadmissibility set out in Article 35 of the Convention. Accordingly, this preliminary objection must be dismissed, as the application cannot be rejected for failure to comply with the procedural rules of the Court (see Tokel v. Turkey, no. 23662/08, §§ 45‑48, 9 February 2021, with further references). 46. In addition, the Court is prepared to accept that the difference between the signatures on the applicants’ passports and those on the authority forms may well be due, as submitted by them, to the long period which elapsed between the issuance of their passports and the signing of the authority forms. Compliance with the six-month time-limit
47. As regards the objection that the applications were lodged outside the six-month time-limit which had been applicable under the Convention at the time of the events, the Court reiterates the following. In the absence of remedies, the time-limit for applicants to lodge their complaints with the Court is to be calculated from the date of the act or decision which is said not to comply with the Convention and, furthermore, it must not apply to a “continuing situation” (see, among many other authorities, Georgia v. Russia (I) (dec.), no. 13255/07, § 47, 30 June 2009). Neither of the respondent Governments submitted that there existed any effective remedies in respect of the applicants’ complaints. Accordingly, the Court finds that, since no effective remedies existed in relation to the applicants’ complaints, it was necessary for them to apply to the Court within six-months from the time when the acts complained of occurred. 48. Bearing in mind that a complaint is always characterised by the alleged facts (see Radomilja and Others v. Croatia [GC], nos. 37685/10 and 22768/12, § 115, 20 March 2018), the Court notes that the applicants complained in the first place that they had been ill-treated at the time of their arrest and subsequently during interrogation (see paragraphs 12 and 14 above). However, they did not explicitly complain, and it cannot be deduced from the material in the case file, that their alleged ill-treatment continued after they had been sentenced on 16 April 2013 (see paragraphs 12 and 14 above). In view of the description provided by the applicants in the context of their complaints under Article 3, and particularly in the absence of specific complaints of physical ill-treatment and/or intense mental suffering caused to them by the de facto Abkhaz authorities after 16 April 2013, the Court finds that such a complaint has not been made before it by either of the applicants. 49. The Court also notes that the applicants’ detention pending trial, falling to be examined under Article 5 § 1 (c) of the Convention, came to an end on 16 April 2013, the date on which they were sentenced. That was also the date when the criminal proceedings against them, in respect of which they complained under Article 6 §§ 1 and 3 of the Convention, ended with their conviction, against which they did not appeal. However, the applicants applied to the Court on 21 August 2015, which was long after the six-month time-limit under the Convention had expired in respect of the above complaints, made specifically under Article 3, Article 5 § 1 (c) and Article 6 §§ 1 and 3. 50. Apart from stating on that point that they had been detained in Abkhazia until their release in March 2016 and that “therefore the situation was of a continuing nature”, the applicants did not in any way explain why or how they had been prevented from applying to the Court within six months from 16 April 2013. In the absence of any indications from the applicants on that point, it is not for the Court to speculate about any possible reasons why they did not submit their applications before it within the time-limit (contrast Mamasakhlisi and Others v. Georgia and Russia, no. 29999/04, §§ 254-55 and 271-74, 7 March 2023). 51. That said, in the exceptional circumstances of this case (compare Mocanu and Others v. Romania [GC], nos. 10865/09 and 2 others, § 275, ECHR 2014 (extracts), and Mamasakhlisi and Others, cited above, § 273), the Court is prepared to accept that being detained in Abkhaz territory by the de facto Abkhaz authorities represented in itself a serious obstacle to the applicants’ applying to the Court within the time-limit required under the Convention. This can be inferred from the applicants’ submission above that access to their relatives and lawyer in Abkhaz territory had been up to the de facto administration (see paragraph 36 above). The Court finds that obstacle sufficient to exempt the applicants from the obligation to comply with the requisite time-limit with regard to their complaints made under Article 3, Article 5 § 1 (c) and Article 6 §§ 1 and 3 (compare Mamasakhlisi and Others, cited above, § 273). 52. The Court further observes that, at the time when they lodged their applications with the Court, the applicants were still being detained, allegedly unlawfully. Consequently, as regards the complaint which falls to be examined under Article 5 § 1 (a) of the Convention, their applications were not submitted outside the six-month time-limit, given that the situations complained of had not come to an end. 53. In the light of the foregoing, the Court considers that the applications were not lodged out of time. The Russian Government’s objection in that regard must therefore be dismissed. Jurisdiction (ratione loci and ratione personae)
54. The general principles have been summarised by the Court in Georgia v. Russia (II) ([GC], no. 38263/08, § 81, 21 January 2021, with further references) and most recently in Ukraine and the Netherlands v. Russia, cited above, §§ 547-75). The essence of those principles is that a State’s jurisdictional authority under Article 1 is primarily territorial, as well as that there are certain exceptions – the spatial concept of jurisdiction and the personal concept of jurisdiction – recognised by the Court as capable of giving rise to the exercise of jurisdiction by a Contracting State outside its own territorial boundaries. In each case, the question of whether exceptional circumstances exist that require and justify a finding by the Court that the State was exercising jurisdiction extraterritorially must be determined with reference to the particular facts (see, among other authorities, Georgia v. Russia (II), cited above, § 82). 55. Article 1 of the Convention reads as follows:
“The High Contracting Parties shall secure to everyone within their jurisdiction the rights and freedoms defined in Section I of [the] Convention.”
56. It follows from Article 1 that member States must answer for any infringement of the rights and freedoms protected by the Convention committed against individuals placed under their “jurisdiction” (see Ilaşcu and Others v. Moldova and Russia [GC], no. 48787/99, § 311, ECHR 2004‑VII). The Court must first determine whether, in respect of the matters complained of, the applicants fell within the jurisdiction of either or both of the respondent States within the meaning of Article 1 of the Convention (compare Catan and Others v. the Republic of Moldova and Russia [GC], nos. 43370/04 and 2 others, § 82, ECHR 2012 (extracts)). 57. In the present case, issues arise as to the meaning of “jurisdiction” with regard to both territorial jurisdiction (in the case of Georgia) and the exercise of extraterritorial jurisdiction (in the case of the Russian Federation). Jurisdiction of Georgia
58. The Court notes that the events of which the applicants complained took place solely in Georgian territory subsequent to its ratification of the Convention on 20 May 1999. On the basis of all the material in its possession, the Court considers that the government of Georgia, the only legitimate government of that State under international law, had no authority over Abkhazia during the period during which the events covered by the applications occurred. It has not been argued otherwise by the parties. 59. In earlier cases (see, among other authorities, Mozer v. the Republic of Moldova and Russia [GC], no. 11138/10, § 99 23 February 2016, with further references, and Mamasakhlisi and Others, cited above, § 318), the Court held that individuals detained in the territorial State had fallen within that State’s jurisdiction even though it had not had effective control over the region in question. The State’s obligation under Article 1 of the Convention to “secure to everyone within [its] jurisdiction the [Convention] rights and freedoms” had, however, been limited in the circumstances to a positive obligation to take the diplomatic, economic, judicial or other measures that were both in its power to take and in accordance with international law (see Ilaşcu and Others, cited above, § 331). 60. The Court sees no reason to distinguish the present case from those cited above and thus finds that the facts of the applications fell within the jurisdiction of Georgia. Although Georgia had no effective control over the acts of the de facto authorities in Abkhazia, the fact that the region was recognised under public international law as part of Georgia’s territory gave rise to a positive obligation for that State, under Article 1 of the Convention, to use all the legal and diplomatic means available to it to continue to guarantee the enjoyment of the rights and freedoms defined in the Convention to those living there (see Ilaşcu and Others, § 333, and Catan and Others, § 109, both cited above). That positive obligation relates both to the measures needed to re-establish its control over Abkhaz territory, as an expression of its jurisdiction, and to measures needed to ensure respect for the individual applicants’ rights. The Court will consider below (see paragraphs 78 to 80, and 88-89 below) whether Georgia has satisfied this positive obligation. Jurisdiction of the Russian Federation
61. The Court must next determine whether the facts complained of by the applicants also fell within the jurisdiction of the Russian Federation. The Court found in Georgia v. Russia (II) (cited above, §§ 174, 175, 295 and 312) that, even after October 2008, the strong Russian presence and the Abkhaz authorities’ dependency on the Russian Federation, on whom their survival had depended, had indicated that the Russian Federation had exercised continued “effective control” over Abkhazia, placing the events which occurred after the cessation of hostilities (12 August 2008) within the jurisdiction of the Russian Federation. The Court further held in its recent decision on admissibility in Georgia v. Russia (IV)((dec.), no. 39611/18, § 44, 20 April 2023) that its conclusion in Georgia v. Russia (II) (cited above, §§ 162-75 and 299) that there had been continued “effective control” of Russia over Abkhazia at least until 23 May 2018 continued to be valid, in the absence of any relevant new information to the contrary. 62. On the basis of the above, it follows that the events complained of by the applicants in the present case, which took place in Abkhaz territory between 15 March 2012 (the date of their arrest) and 10 March 2016 (the date of their release), fell within the jurisdiction of the Russian Federation. The Russian Government’s objection ratione loci must therefore be dismissed. ALLEGED VIOLATION OF ARTICLE 3 OF THE CONVENTION
63. The applicants complained that they had been repeatedly tortured at the time of their arrest and during their subsequent detention. They relied on Article 3, which reads as follows:
“No one shall be subjected to torture or to inhuman or degrading treatment or punishment.”
64. The two respondent Governments did not submit specific observations in respect of this complaint. Their comments in respect of the allegations in the applications more generally have been summarised in paragraph 8 above. 65. The Court, for the reasons which follow immediately below, finds that the applicants’ complaints under Article 3 are inadmissible. 66. Undoubtedly, the Convention prohibits in absolute terms torture and inhuman and degrading treatment, irrespective of the victim’s conduct (see, among many other authorities, Labita v. Italy [GC], no. 26772/95, § 119, ECHR 2000-IV, and Selmouni v. France [GC], no. 25803/94, § 95, ECHR 1999-V). Furthermore, where the events at issue lie wholly, or in large part, within the exclusive knowledge of the authorities, as in the case of persons under their control in custody, strong presumptions of fact will arise in respect of injuries occurring during such detention. Indeed, the burden of proof may be regarded as lying with the authorities to provide a satisfactory and convincing explanation (see Ribitsch v. Austria, 4 December 1995, § 34, Series A no. 336, and Salman v. Turkey [GC], no. 21986/93, § 100, ECHR 2000‑VII). 67. Notwithstanding the above, allegations of ill-treatment must be supported by appropriate evidence (see, among many other authorities, Jalloh v. Germany [GC], no. 54810/00, § 67, ECHR 2006‑IX). To assess this evidence, the Court adopts the standard of proof “beyond reasonable doubt” yet considers that such proof may follow from the coexistence of sufficiently strong, clear and concordant inferences or of similar unrebutted presumptions of fact (ibid.). 68. The Court is aware that the applicants were kept in detention for approximately three years subsequent to the alleged torture and therefore had a limited ability to secure or gather evidence for such treatment (see paragraphs 12-14 and 51 above). Nevertheless, the Court cannot but note that the applicants did not submit medical certificates attesting to any physical after‑effects of their detention in Abkhazia (compare Mangîr and Others v. the Republic of Moldova and Russia, no. 50157/06, § 47, 17 July 2018 and Tanış v. Turkey (dec.), no. 15442/08, §§ 46-49, 9 February 2016). Likewise, they did not submit any reports of psychological evaluations carried out after their release (contrast Mamasakhlisi and Others, cited above, § 389). The Court has already emphasised the importance of independent and thorough examinations of persons on release from detention (see Akkoç v. Turkey, nos. 22947/93 and 22948/93, § 118, ECHR 2000‑X). In view of the description provided by the applicants of ill-treatment (see paragraphs 12 and 14 above), medical reports prepared subsequently to their release could have provided relevant prima facie evidence if they had recorded, for example, possible signs of any physical injuries or psychological effects that the alleged ill-treatment might have had on them (compare and contrast Mamasakhlisi and Others, cited above, §§ 390 and 395). Furthermore, the applicants have not provided any other evidence, such as, for example, statements made by their lawyer or their family members, to corroborate their version of the events (compare, mutatis mutandis, Borodin v. Russia, no. 41867/04, § 99, 6 November 2012, and Mangîr and Others, cited above, § 47). 69. Accordingly, although the applicants provided a rather detailed account of their alleged ill-treatment, the Court is unable, on the basis of the materials submitted, to find prima facie that they were subjected to the ill‑treatment alleged. 70. The Court accordingly finds that the applicants’ complaints under Article 3 of the Convention are inadmissible as being manifestly ill-founded and must be rejected in accordance with Article 35 §§ 1 and 4 of the Convention. ALLEGED VIOLATION OF ARTICLE 5 § 1 (a) and (c) OF THE CONVENTION
71. The applicants complained that they had been detained unlawfully in Abkhazia. They relied on Article 5 § 1 of the Convention. The Court considers that this complaint concerns the applicants’ allegedly unlawful detention pending trial and their continued unlawful detention after their conviction on 16 March 2013, which fall to be examined under Article 5 § 1 (a) and (c) of the Convention respectively, which reads as follows:
Article 5 § 1 (a) and (c)
“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:
(a)  the lawful detention of a person after conviction by a competent court;
... (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;”
   Admissibility
72. The Court notes that these complaints are neither manifestly ill‑founded nor inadmissible on any other grounds listed in Article 35 of the Convention. They must therefore be declared admissible. Merits     The parties’ submissions

73. The applicants submitted that Georgia had been aware of the violations of the applicants’ Convention rights since 2012 when they had been detained in Abkhazia but the Georgian authorities had not taken any measures before May 2015 to put an end to those violations (see paragraphs 22 and 36 above). 74. In addition to their general comments in respect of the allegations made by the applicants (which have been summarised in paragraph 8 above), the two respondent Governments stated as follows. The Russian Government emphasised the absence of causal links between the acts of the Russian Federation and the alleged violations of the applicants’ rights. The Georgian Government submitted that they did not contest that the applicants had been unlawfully arrested and had remained in unlawful detention between 15 March 2012 and 10 March 2016. The Court’s assessment
75. It is well established in the Court’s case-law under Article 5 § 1 of the Convention that any deprivation of liberty must not only be based on one of the exceptions listed in sub-paragraphs (a) through (f) but must also be “lawful”; this necessitates that it have a legal basis in domestic law and that it be compatible with the rule of law, a concept inherent in all the Articles of the Convention. 76. Previously, in Mamasakhlisi and Others (cited above, §§ 422-28), the Court, for the first time, examined complaints concerning unlawful arrest and detention, both pending trial and following conviction, ordered by the de facto Abkhaz authorities in the period before 14 February 2007. Referring to the lack of information provided by the respondent Governments about the specific provisions of domestic law that had served as a legal basis, to the scarcity of official sources of information concerning the legal and court system in Abkhazia as well as to the absence of a basis for assuming that there was a system reflecting a judicial tradition compatible with the Convention in the region similar to the one in the rest of the Georgia, the Court found that the de facto authorities and courts could not order the applicants’ “lawful arrest or detention” within the meaning of Article 5 § 1 (a) and (c) of the Convention. The Court held that the applicants’ arrest and detention had been unlawful for the purposes of that provision, in violation of Article 5 § 1 (a) and (c) of the Convention. 77. In the absence of any new and pertinent information to the contrary, the Court considers that the conclusion reached in Mamasakhlisi and Others (ibid.) is also valid in the present case.
