"The Court cannot accept, however, that an absolute bar on voting by any person under partial guardianship, irrespective of his or her actual faculties, falls within an acceptable margin of appreciation. Indeed, while the Court reiterates that this margin of appreciation is wide, it is not all-embracing (Hirst v. the United Kingdom (no. 2) [GC], op. cit., § 82). In addition, if a restriction on fundamental rights applies to a particularly vulnerable group in society, who have suffered considerable discrimination in the past, such as the mentally disabled, then the State's margin of appreciation is substantially narrower and it must have very weighty reasons for the restrictions in question (cf. also the example of those suffering different treatment on the ground of their gender - Abdulaziz, Cabales and Balkandali v. the United Kingdom, 28 May 1985, § 78, Series A no. 94, race - D.H. and Others v. the Czech Republic [GC], no. 57325/00, § 182, ECHR 2007-..., or sexual orientation - E.B. v. France [GC], no. 43546/02, § 94, ECHR 2008-...). The reason for this approach, which questions certain classifications per se, is that such groups were historically subject to prejudice with lasting consequences, resulting in their social exclusion. Such prejudice may entail legislative stereotyping which prohibits the individualised evaluation of their capacities and needs (cf. Shtukaturov v. Russia, no. 44009/05, § 95, 27 March 2008). "
