The Formulation of a Normative Standard of Judicial Impartiality that Incorporates Objective-Cognitive Impartiality in Peruvian Legal System: A Study on the Repercussion of the Jurisprudence of International Human Rights Courts.

This article is a case study on the configuration of the duty of impartiality in the jurisprudential development of human rights courts and its influence on Peruvian domestic courts. In this line of reasoning, the way in which the distinction between subjective and objective impartiality-identified with the “theory of appearances-has been constructed is analyzed and, later, the relationship between impartiality and cognitive bias is determined. This is done with the aim of criticizing the theory of appearances and proposing the formulation of a standard in which three dimensions of the guarantee of impartiality are distinguished: subjective, objective-functional and objective-cognitive. Finally, the distinction between external and internal judicial independence is addressed, and its difference with impartiality is determined.

Keywords : Duty of judicial impartiality; jurisprudence of international human rights courts; subjective judicial impartiality; objective judicial impartiality; cognitive biases.
