The constitutional amendments in 2017 have led to significant changes on the structure of the executive branch and accordingly, the powers of the President have been rearranged. One of the powers that was granted to the President by the amendments is the power of issuing a Presidential decree which is different from previous regulatory decrees in many aspects. Al- though there are some similarities between the Presidential decrees and the other decrees, the Presidential decrees differs from the others in terms of procedure, fundamental principles, sub- ject, judicial review procedure, and the position in the hierarchy of laws. Moreover, since the President has the primary regulative power, the Presidential decrees must be discussed in the context of the legislative power. In this article, the Presidential decrees are examined under two headings as the ordinary Presidential decrees and the state of emergency Presidential decrees. Furthermore, the questions that may be arisen from the amendments are tried to be solved.
