This report assesses the ways in which the semi-presidential form of government can be best structured to promote stable, democratic and inclusive governance in Ukraine. Constitutional stability in Ukraine has faced four main challenges: (a) recurring institutional conflict among the president, legislature and government; (b) a presidency that has fallen prey to autocratic tendencies; (c) a fragmented and weak party system that has undermined the capacity of the legislature to act coherently; (d) a weak constitutional culture and a weak Constitutional Court. The report presents comparative knowledge from other semi-presidential systems, and reflections on the Ukrainian context, which could benefit a wide range of stakeholders, such as legislators, policy advisors, think tanks and civil society.
