The knowledge and perspectives gained through these exchanges are of particular importance in the context of Ukraine’s ongoing preparations for accession to the European Union. We greatly value your openness, professional cooperation and warm hospitality, which made the visit both professionally enriching and especially rewarding for the delegation.

We are sincerely grateful for the opportunity provided to the delegation to hold meetings with representatives o f Estonia’s key institutions involved in safeguarding constitutional governance, including representatives of the Supreme Court o f Estonia, Office of the Chancellor of Justice, the Ministry of Justice and Digital Affairs, and the Constitutional Committee of the Parliament of Estonia. These meetings offered valuable insights into Estonia’s constitutional framework and institutions and provided an opportunity to discuss issues of particular relevance to our respective legal systems.

The delegation of the Constitutional Court of Ukraine would like to express its gratitude to Mr Ullar Kaljumae, Director of the Supreme Court of Estonia, and to all the staff of the Supreme Court of Estonia, and in particular to Ms Karin Leichter-Tammisto, Legal Adviser to the President of the Supreme Court o f Estonia, whose dedicated efforts, professionalism and warm hospitality contributed greatly to the success of the visit. The warm impressions the delegation brought back from Estonia, together with the kindness and genuine warmth extended by our Estonian colleagues, will remain with its members for a long time to come.

We are confident that this visit has further strengthened the friendly relations between our institutions and laid a solid foundation for continued cooperation, professional exchange and mutual support in the field of constitutional justice.

Please accept, Mr President, the assurances of my highest considération and esteem.
