Four deputies of Yekaterinburg's City Duma have filed suit seeking to disallow the results of the legislature's session last Tuesday, which inaugurated the newly-elected opposition candidate Yevgeny Roizman.
Members of Just Russia and the Russian Party of Pensioners for Justice said all the decisions made by the city's governing body on Sept. 24 should be cancelled because the session was conducted without a quorum, RIA Novosti reported.
Their complaint is set to be considered by the court on Thursday.
The new mayor disagreed with the claims provided in the complaint, but said the city's court will have the last word in resolving the dispute.
Deputies from both Just Russia and the Russian Party of Pensioners for Justice were not present at the City Duma's first session under Roizman last Tuesday, hoping to draw attention to violations during the city's elections on Sept. 8.
