Between 1909 and 1915, Nekrasov was a member of the Kadets' Central Committee, where he was consistently Left of center. He delivered the Kadets' parliamentary interpellation on April 9, 1912 after the Lena massacre, denouncing what he described as the government's illegal interference in an economic dispute between labor and capital on the side of the latter. Later in 1912 Nekrasov argued that "constructive work" within the Duma had been made impossible by the Tsarist government and that the party should be more confrontational and use the Duma for anti-government propaganda instead of lawmaking. On June 11, 1915 he resigned from the Central Committee over what he saw as the majority's willingness to give the government a blank check during World War I.
