On 18 May 2007, the Parliament of Kazakhstan approved a constitutional amendment which allowed the incumbent president—himself—to run for an unlimited number of five-year terms. This amendment applied specifically and only to Nazarbayev: the original constitution's prescribed maximum of two five-year terms will still apply to all future presidents of Kazakhstan. That same year in August, legislative elections were held from which the Nur Otan won all the contested seats in the Mazhilis, eliminating any form of opposition which sparked controversy and criticism from international organizations and groups within the country. In response, Kazakhstan introduced an amendment by allowing for a two-party system since any party that wins 2nd place in race regardless or not if it passes the 7% electoral threshold is guaranteed to have representation in the Parliament.
