"We need to see how the law will pass. There is still room for change in the General Assembly," Gul said during a joint conference with Georgian President Giorgi Margvelashvili.
The proposed bill to restructure the Supreme Board of Judges and Prosecutors (HSYK) was approved by a parliamentary commission on Thursday. If passed by the Parliament, it will be submitted to President Gul for ratification.
"Let the bill pass first; then you will see what I will do," Gul said.
The bill proposes transferring some of the powers of the HSYK to its chair - Justice Minister Bekir Bozdag.
AK Party had earlier sought partnership with opposition parties for a constitutional amendment to change the HSYK. The plan fell by the wayside after the two largest opposition parties - CHP and MHP - rejected AK Party's offer.
