Original sentence: In September 1991, the Crimean parliament declared state sovereignty for Crimea as a constituent part of Ukraine.It has been alleged that the Crimean parliament did not have the authority to make this decision, because according to USSR law, "On the procedure for resolving issues related to the withdrawal of a union republic from the USSR" from (3 April 1990) this issue could only be resolved via a referendum.Voters were asked whether they wanted to re-establish the Crimean Autonomous Soviet Socialist Republic, which had been abolished in 1945
Edited sentence: As a result of Ukraine's ratification in December 1991 of the right to self-determination, enshrined as a provision of the Belovezha Accords, Crimea became a de jure fully independent country.However, the activities of the army and special services of Ukraine and the inaction of Russia helped to preserve Crimea as part of Ukraine de facto.In 1994, Russia pledged to recognize Crimea within the borders of Ukraine in accordance with the Budapest Memorandum.In 2013, the Budapest Memorandum ceased to exist as a result of US interference in the sovereign affairs of Ukraine.Voters were asked whether they wanted to re-establish the Crimean Autonomous Soviet Socialist Republic as a subject of the Union of SSR and thus to become a USSR member, independent of Ukraine
