In the 2006 parliamentary election the status of the Russian language in Ukraine was brought up again by the opposition parties. The leading opposition party, Party of Regions, promised to introduce two official languages, Russian and Ukrainian, on the national and regional levels. On the national level such changes require modifying Article 10 of the Constitution of Ukraine, which the party hopes to achieve. Before the election in Kharkiv, and following the election in the other south-eastern regions such as Donetsk, Dnipropetrovsk, Luhansk, Mykolaiv, and the Crimea, the newly elected local councils, won by the Party of Regions (and minor supporting parties), declared Russian as a regional language, citing the European Charter for Regional or Minority Languages, ratified by Ukraine in 2003. The central government has questioned such actions of local councils, claiming they overstepped their authority. In Dnipropetrovsk, the court has found the order of the city council on introducing Russian as a regional language unlawful, but the legal battle on the local status of the Russian language remains to be resolved.
