"The Court reiterates, having regard to the parties’ submissions which are summarised above, in paragraphs 60 et seq. and 72 et seq., that “the scope of the Contracting States’ obligations under Article 13 varies depending on the nature of the applicant’s complaint; ... the remedy must be effective in practice as well as in law in the sense either of preventing the alleged violation or remedying the impugned state of affairs, or of providing adequate redress for any violation that has already occurred” (see Petkov and Others v. Bulgaria, nos. 77568/01, 178/02 and 505/02, § 74, 11 June 2009). The Court also reiterates that “although no single remedy may itself entirely satisfy the requirements of Article 13, the aggregate of remedies provided for under domestic law may do so” (see Kudła v. Poland [GC], no. 30210/96, § 157, ECHR 2000‑XI). "
