The paper highlights the particularities of the Estonian case study and the added value of the Estonian ECIs. I believe the Estonian case study has much to tell for both the IMAGINE project and Europe at large. I see the Estonian uniqueness in three main aspects. First, the cultural, economic and geopolitical positioning which has brought about a strong security paradigm complemented by a mild economic one. Second, the specific aspects of Estonian constitutional theory and practice and how it relates to EU law, especially in light of Estonia’s portrayal as one of the most liberal and EU-enthusiastic countries. Third, the perks and pitfalls of being such a small and dynamic country, especially the importance and experience of the bold reforms done in 1990s, most notably the large-scale judicial reform. All of these are in many ways different from other IMAGINE case studies and will hopefully uncover a special vision of ECIs.
