ANATOLIY MARINOV v. BULGARIA JUDGMENT an effective remedy. It follows that the application cannot be rejected for non-exhaustion of domestic remedies. (c) Regarding the abuse of the right of individual petition 30. The Court reiterates that, according to its case-law, an application is an abuse of the right of application if it is knowingly based on untrue facts with a view to deceiving the Court (see, among other authorities, X and Others v. Bulgaria [GC], no. 22457/16, § 145, 2 February 2021). Furthermore, the submission of incomplete and thus misleading information may also amount to an abuse of the right of application, especially if the information concerns the very core of the case and no sufficient explanation has been provided for the failure to disclose that information (see Gross v. Switzerland [GC], no. 67810/10, § 28, ECHR 2014). The same applies if important new developments have occurred during the proceedings before the Court and if, despite being expressly required to do so by Rule 47 § 7 of the Rules of Court, the applicant has failed to disclose that information to the Court, thereby preventing it from ruling on the case in full knowledge of the facts. However, even in such cases, the applicant’s intention to mislead the Court must always be established with sufficient certainty (see Centro Europa 7 S.r.l. and Di Stefano v. Italy [GC], no. 38433/09, § 97, ECHR 2012). 31. Turning to the circumstances of the present case, the Court has no basis to conclude that the applicant intentionally submitted facts which he knew to be false. In addition, the Court considers that while it is true that, in his initial application, the applicant did not provide the information specified by the Government, that information cannot be deemed to be essential for deciding the outcome of the application. The Court gives particular weight to the fact that the applicant’s complaint questions the automatic constitutional ban on his right to vote after he was declared legally incapable – regardless of whether or not his legal capacity is restored to him in the future. The Court has already noted that the proceedings for restoring the applicant’s legal capacity do not relate sufficiently to the core issue highlighted in the present complaint (paragraphs 27-29 above). 32. Accordingly, the Court rejects the Government’s preliminary objection that the applicant’s conduct constituted an abuse of the right of application within the meaning of Article 35 § 3 (a) in fine of the Convention. (d) Conclusion on the admissibility 33. The Court notes that the application is neither manifestly ill-founded nor inadmissible on any other grounds listed in Article 35 of the Convention. It must therefore be declared admissible. 8
