The article draws attention to how integrative interpretation – a methodology where the European Court of Human Rights integrates its normative environment into the interpretation of the European Convention of Human Rights – may offer an important path to bridging many of the challenges caused by fragmentation in the field of human rights. More specifically, the article offers insight into a selection of ECHR cases that are characterised by the existence of normative overlap between the ECHR, the CEDAW and the CRC; and by the fact that interaction between these legal sources actually takes place in the interpretation carried out by the Court. Interaction is discussed through two topics: the issue of state obligations in relation to domestic violence, and the issue of state obligations in relation to expulsion of immigrants with children. The article demonstrates that systemic integration may result in a strengthening of the protection of human rights under ECHR through what is termed ‘interpretive widening and thickening’.
