The regulation is in the final provisions of the bill. Full text (in Ukrainian) is available on the Parliament’s official website.
In particular, the Transitional Provisions section contains following regulations to become valid after the entry into force of the Law "On Amendments to the Constitution of Ukraine” (regarding the decentralization of power)," "the next regular local elections - the elections of community leaders, members of community councils, district and regional councils shall be held on the last Sunday of October 2017."
"The authority of village, town and city mayors and deputies of the local councils elected in the next regular elections in October 2015 and local elections held from October 2015 to October 2017 shall be terminated from the day of gaining powers by the respective chairmen of communities, community councils, district and regional councils, elected at the next regular local elections in October 2017," reads the bill.
The final provisions of the bill also state that "the district and regional councils, elected at the next regular local elections in October 2017, create executive committees under the law on local governing, which defines the powers of the executive committees of district and regional councils."
Ukrainian President Petro Poroshenko earlier said that he saw no need for early parliamentary elections in the wake of presenting draft amendments to the Fundamental Law.
