168Furthermore, it is apparent from the case-law of the European Court of Human Rights that the expression ‘established by law’ in Article 6(1) ECHR concerns not only the legal basis for the very existence of the tribunal but also the composition of the bench in each case. The purpose of that expression is to prevent the organisation of the judicial system from being left to the discretion of the executive and to ensure that that matter is governed by a law. Nor, moreover, in codified law countries, can the organisation of the judicial system be left to the discretion of the judicial authorities, which does not, however, rule out conferring on them a certain power to interpret the relevant national legislation. Furthermore, the delegation of powers in matters relating to judicial organisation is acceptable in so far as that possibility falls within the framework of the national law of the State in question, including the relevant provisions of its Constitution (see, inter alia, ECtHR, 28 April 2009, Savino and Others v. Italy, CE:ECHR:2009:0428JUD001721405, §§ 94 and 95 and the case-law cited).
