Full list of publications 

Ingrid Leijten’s research deals with the protection of fundamental rights at the international, European, national and local level, with a particular focus on the European Convention on Human Rights (ECHR) and social rights protection. Fascinated by the internationalisation and constitutionalisation of public law, she investigates the role of rights in relation to the work of different governmental powers.

In her monograph Core Socio-Economic Rights and the European Court of Human Rights (CUP 2018), she discusses the protection of social rights under the ECHR. The work includes a comparative study of core fundamental rights protection at the national, constitutional, and international level and deals with issues ranging from social security and environmental protection as fundamental rights issues to minimum protection for (undocumented) migrants. For more information on the book, see CUP’s website. Currently, Leijten is editing an interdisciplinary volume on the topic of a social minimum (forthcoming with Hart Publishing).

Other projects deal with fundamental rights interpretation and reasoning; proportionality, reasonableness, and alternatives; the legislator and executive as fundamental rights protectors; social security and property rights, and the relation between national and supranational rights protection. Leijten’s work appeared in, amongst others, the Human Rights Law Review, the German Law Journal, and the Tijdschrift voor Constitutioneel Recht, as well as in various edited volumes, such as Shaping Rights (CUP 2014). She also publishes case notes and blog posts, covering case law developments and other current fundamental rights issues. Besides in the form of publications, Ingrid Leijten regularly presents her work at (international) conferences, seminars, and workshops, as well as to judges and government bodies.

Ingrid Leijten teaches various courses in constitutional law and in international and European human rights law (LLB, LLM, and Advanced LLM level). These include Beginselen van de democratische rechtsstaat (Principles of the Democratic Rechtsstaat); Constitutionele Vraagstukken in Europese Context (Constitutional Law in a European Context); European Human Rights Law; Human Rights Conceptions in a Pluralist World, and Privatissimum European and International Human Rights Law. In addition, she supervises LLB and (Adv.) LLM theses on topics related to her research interests.
