L'influence des marqueurs identitaires du juge dans les décisions relatives à la garde des enfants dans un contexte post-rupture

The “best interest of the child” is a fundamental concept of family law as it is the decisive criterion in each decision concerning a child. The Civil Code of Québec enumerates, in art. 33 para. 2, the criteria that must be taken into consideration, which are “the moral, intellectual, emotional and physical needs of the child, [his] age, health, personality and family environment, and [the] other aspects of his situation”. Scholars have approached this concept from different angles. While some of them have expressed interest in its origin and evolution, others have articulated their own definition. In this thesis, I chose to explore the concept of the “best interest of the child” by examining the manner in which courts have interpreted this principle in cases related to child custody, and to what extent it is affected by the gender and the age of the decision-maker. Indeed, whenever a child is part of a conflict, regardless of whether it concerns custody or any other matter, his best interest constitutes the central element. Yet the concept of the child's best interest is highly indeterminate: its interpretation is left to the discretion of the judge, who will specify its content according to the law and facts of each case. But once the judge has considered the factual and normative contexts, he can sometimes face a « neutral » situation, for which he could consider sole and shared custody as options. Would it therefore be accurate to assume that the judge’s inclination toward one or the other option of custody is governed by elements other than the law and facts of the case? This is the main question of this study. Based on recognized and well established theories asserting the importance of considering the social context and individual experience of the decision maker in the interpretative process, the proposed hypothesis is that beyond the facts and the law, there are other elements that have a crucial influence on the process of interpretation (and on the content of the decision that a judge renders), most notably the identity profile of the judge (i.e., gender and age, including their underlying values and ideologies). Indeed, and although the values, ideologies, and dominant social characteristics are not sufficient in themselves to explain the judicial outcomes, I nevertheless consider that the impact that the former has on the latter cannot be denied. By examining the cognitive process that governs the reasoning of the decision maker, this thesis aims to identify, through interdisciplinary analysis, human factors and social forces that shape individual experiences and are likely to have an impact on judicial decisions. The objective of this research is not to establish a causal link between the profile of the judge and his/her decisions, but rather to determine whether a correlation can be established between these parameters. Wishing to go beyond traditional perceptions conveyed by the traditional doctrine, this thesis is a contribution to the development of a non-formalist conception of law, as a way of demonstrating the idea that the profile of the judge systematically and consistently frames his decisions.  A study of this kind certainly faces difficulties, in that it confronts the lawyer with concepts and theories that belong to other disciplines, and which therefore may not be familiar. However, the deep understanding of the interpretive process and resulting decisions justify the importance of this kind of research.
