Ukrainians in the Russian Federation represent the third-largest ethnic group after Russians and Tatars. In spite of their relatively high numbers, some Ukrainians in Russia complain[when?] of unfair treatment and anti-Ukrainian sentiment in the Russian Federation.[27][28] In November 2010, the High Court of Russia cancelled registration of one of the biggest civic communities of the Ukrainian minority, the "Federal nation-cultural autonomy of the Ukrainians in Russia" (FNCAUR).[29]
