To facilitate the annexation politically, the Russian-backed Crimean parliament and the Sevastopol City Council announced on 6 March, in violation of the Ukrainian Constitution, a referendum on the issue of joining Russia, to be held on 16 March. The upcoming vote allowed citizens to vote on whether Crimea should apply to join Russia as a federal subject of the Russian Federation, or restore the 1992 Crimean constitution and Crimea's status as a part of Ukraine. The available choices did not include keeping the status quo of Crimea and Sevastopol as they were at the time the referendum was held.
