Over the past years, Ingrid Leijten has been working on her PhD thesis, which focuses on the development of the rights laid down in the European Convention on Human Rights and in particular on the socio-economic dimension of these rights. It deals with the question of how the European Court of Human Rights can navigate between providing effective and individual as well as principled fundamental rights protection, while at the same time taking account of its institutional position and showing deference towards (the social policies of) the Member States. In the light of this, the thesis explores the possible use and added value of the notion of ‘core rights’ for the reasoning of the ECtHR in socio-economic cases. By means of a comparative study of (the theoretical underpinnings of) the German  Wesensgehaltsgarantie, the minimum core obligations that have been recognized in the context of the International Covenant on Economic, Social and Cultural Rights, and the debate on the use of core rights for the protection of socio-economic rights under the South African Constitution, insights are gained on the possibilities and pitfalls inherent in the idea of core rights protection. On the basis thereof, Ingrid Leijten has developed a ‘core rights perspective’ that is tailored to the protection of socio-economic interests by the ECtHR. It is argued that this perspective allows the ECtHR to develop a principled approach to the adjudication of (positive) socio-economic claims that is characterized by a clear demarcation of the scope of the Convention and a focus on minimum guarantees, the protection of vulnerable individuals and non-discrimination. In this way the core rights perspective may help the ECtHR in leaving the necessary room for national laws and policies while ensuring robust socio-economic protection.
