In 1993 Sumin won the first election of the Head of Administration of Chelyabinsk Oblast, gaining more than 50% of the votes. However, the results of the elections were canceled, despite the decision of the Constitutional Court of Russia recognising legality of Sumin's election. Until October 1993 there were two administrations in the region, led by Pyotr Sumin and Vadim Solovyov respectively. In October 1993, after the dissolution of the Supreme Soviet, President Boris Yeltsin confirmed Solovyov's powers.
