128As regards the condition of ‘impartiality’, within the meaning of Article 6(1) of the ECHR, impartiality can, according to equally settled case-law of the European Court of Human Rights, be tested in various ways, namely, according to a subjective test where regard must be had to the personal convictions and behaviour of a particular judge, that is, by examining whether the judge gave any indication of personal prejudice or bias in a given case; and also according to an objective test, that is to say by ascertaining whether the tribunal itself and, among other aspects, its composition, offered sufficient guarantees to exclude any legitimate doubt in respect of its impartiality. As to the objective test, it must be determined whether, quite apart from the judge’s conduct, there are ascertainable facts which may raise doubts as to his or her impartiality. In this connection, even appearances may be of a certain importance. Once again, what is at stake is the confidence which the courts in a democratic society must inspire in the public, and first and foremost in the parties to the proceedings (see, inter alia, ECtHR, 6 May 2003, Kleyn and Others v. Netherlands, CE:ECHR:2003:0506JUD003934398, § 191 and the case-law cited, and 6 November 2018, Ramos Nunes de Carvalho e Sá v. Portugal, CE:ECHR:2018:1106JUD005539113, §§ 145, 147 and 149 and the case-law cited).
