The ballot asks two questions and leaves no option for a no vote. Voters are simply asked to check one of two boxes:
Do you support joining Crimea with the Russian Federation as a subject of Russian Federation?
And:
Do you support restoration of 1992 Crimean Constitution and Crimea’s status as a part of Ukraine?
That Constitution declares that Crimea is an independent state.
From the start, when Crimea has been detached from SSR of Russia and attached to the Soviet Socialist Republic of Ukraine , integrated part of the Soviet !union, by N.Krustchev in 1954, Crimea has had a SPECIAL statute: of an autonomous republic with its own Constiution, parliment, laws, government and independent budget. As such, the republic, according with the UN Charter has the right to declare its independence and sovereignity, if the people wish it.
