In this article, we analyse and discuss the legal criteria granting access to facilitated naturalisation in Switzer- land. Among the possible legal criteria, marriage to a Swiss citizen as a criterion for obtaining citizenship is em- blematic of the conservative political background in this country. It is also influenced by gendered stereotypes within the law itself and its application. We argue in fa- vour of a critical approach to the law in order to avoid the erasure of categories of individuals who are relegated to society’s margins. In a healthy democracy and judicial system, the law ought to be designed so as to avoid repro- ducing exclusionary bias. In this regard, we also discuss why acceding to citizenship is a prerequisite for exercis- ing one’s political rights and thus, achieving inclusion in Switzerland.
