Abstract
This study explores Turkey’s 2017 constitutional amendments, which signify a structural transformation from a parliamentary to a semi-presidential system. The research highlights the increasing powers of the president, including veto authority and diminished parliamentary oversight. Using a legal-analytical approach, the study examines the implications of these changes on the balance between the legislative and executive branches. The central hypothesis posits that the amendments weakened parliamentary control, consolidating executive power. Findings indicate a shift toward Presidential, with the abolition of mechanisms like parliamentary interpellation, confirming a major change in the political structure.
