The Common European Asylum System (CEAS) has been in a constant state of development since its conception in 1999, however the 2015 European refugee crisis demonstrated the need for several adjustments to be made. Since then, engagement between the European Union and Member States over what the future of this system could look like has increased. This thesis builds on existing Europeanisation and de-Europeanisation research by operationalising these concepts to use as lenses through which to view the EU’s engagement with the Swedish state over the sovereignty and responsibility and border management aspects of the CEAS following the peak of the 2015 refugee crisis. Employing data in the form of policy documents and speech transcripts from the Swedish Ministry of Justice and the EU, this thesis conducts a qualitative content analysis to examine the discourse between the two actors and determine whether or not dynamics of Europeanisation or de-Europeanisation can be identified. The results of this study conclude that dynamics of Europeanisation can be identified in the engagement between the Swedish Ministry of Justice and the EU over the solidarity and responsibility aspect of the CEAS while dynamics of de-Europeanisation can be identified in relation to discourse surrounding border management.
