26 MAGYAR KÉTFARKÚ KUTYA PÁRT v. HUNGARY JUDGMENT B. The parties’ submissions 1. The Government 50. The Government objected before the Grand Chamber that the applicant had failed to exhaust domestic remedies in the form of the constitutional complaint provided for in section 26(2) of the Constitutional Court Act (“the CCA”), through which the MKKP could have argued before the Constitutional Court that the Kúria had applied legislation which was in contravention of the Fundamental Law. The Government further submitted that although the MKKP had lodged a complaint under section 27 of the CCA against the Kúria’s decisions, and had thus formally exhausted that option, it had not established its direct interest in the case, which was a precondition of admissibility under domestic law. 2. The MKKP 51. The MKKP did not comment on this issue. C. The Court’s assessment 52. The Court reiterates first of all that under Article 35 § 1 it may only deal with a matter after all domestic remedies have been exhausted. Applicants must have provided the domestic courts with the opportunity, in principle intended to be afforded to Contracting States, of preventing or putting right the violations alleged against them. That rule is based on the assumption that there is an effective remedy available in the domestic system in respect of the alleged breach. The only remedies which Article 35 § 1 requires to be exhausted are those that relate to the breach alleged and are capable of redressing the alleged violation. The existence of such remedies must be sufficiently certain not only in theory but also in practice, failing which they will lack the requisite accessibility and effectiveness: it falls to the respondent State to establish that these conditions are satisfied (see, among many other authorities, McFarlane v. Ireland [GC], no. 31333/06, § 107, 10 September 2010; Vučković and Others v. Serbia (preliminary objection) [GC], nos. 17153/11 and 29 others, §§ 69-77, 25 March 2014; and Parrillo v. Italy [GC], no. 46470/11, § 87, ECHR 2015). 53. In several cases the Court has considered that domestic remedies were exhausted for the purposes of Article 35 § 1 of the Convention despite the fact that the applicant’s constitutional complaint had been dismissed as inadmissible, as the substance of the complaint had been sufficiently raised before the Constitutional Court (see, inter alia, Gäfgen v. Germany [GC], no. 22978/05, § 144, ECHR 2010; see also Uhl v. Germany (dec.), no. 64387/01, 6 May 2004; Storck v. Germany, (dec.), no. 61603/00,
