Impact of presidential system on separation of powers in Türkiye

As a result of the system change discussions that accelerated after the 2016 coup attempt and a series of constitutional changes, Türkiye switched from a parliamentary democracy to a Turkish-style presidential system in 2018. As a result of the adoption of this new and unique system, which has similarities and differences with other presidential systems, the office of prime minister in the executive body was abolished and the executive power was concentrated in the hands of a single person. Changes in the executive organ inevitably affected the other organs of the state, namely the legislature and the judiciary. For this reason, serious changes have occurred in the relations of executive, legislative and judicial organs both within themselves and with each other. As a result of these changes, wide-ranging debates began in the direction that a more stable Türkiye would be possible by eliminating the dualism in the executive, or that the executive would result in an anti-democratic Türkiye by taking advantage of the increased power and authorities to control the other state organs. Considering that the principle of separation of powers is indispensable for democracies and that it strengthens the democratic administration against authoritarian regimes, effect of the presidential system on the principle of separation of powers will be investigated within the scope of this thesis.
