The transfer of the Crimean Oblast in 1954 was an administrative action of the Presidium of the Supreme Soviet of the Soviet Union which transferred the government of the Crimean peninsula from the Russian Soviet Federative Socialist Republic to the Ukrainian SSR.
On 19 February 1954 the Presidium of the Supreme Soviet of the Soviet Union issued a decree transferring the Crimean Oblast from the Russian Soviet Federative Socialist Republic to the Ukrainian SSR. According to the Soviet Constitution (article 18), the borders of a republic within the Soviet Union could not be re-drawn without the agreement of the republic in question. The transfer was approved by the Presidium of the Supreme Soviet of the Soviet Union; however, according to article 33 of the constitution, the Presidium did not have the authority to do so. The constitutional change (articles 22 and 23) to accommodate the transfer was made several days after the decree issued by the Presidium of the Supreme Soviet.
The decree was first announced, on the front page of Pravda, on 27 February 1954. The full text of the decree was:
"Decree of the Presidium of the USSR Supreme Soviet transferring the Crimea Province from the Russian SFSR to the Ukrainian SSR.
Taking into account the integral character of the economy, the territorial proximity and the close economic and cultural ties between the Crimea Province and the Ukrainian SSR, the Presidium of the USSR Supreme Soviet decrees:
According to Russian website Pravda.ru the Presidium of the Supreme Council gathered for a session on February 19, 1954 when only 13 of 27 members were present. There was no quorum, but the decision was adopted unanimously.
The earlier published documents, and materials that have emerged more recently, confirm that the transfer of Crimea from the Russian SFSR to the Ukrainian SSR was carried out in accordance with the 1936 Soviet constitution, which in Article 18 stipulated that "the territory of a Union Republic may not be altered without its consent." The proceedings of the USSR Supreme Soviet Presidium meeting indicate that both the Russian SFSR and the Ukrainian SSR had given their consent via their republic parliaments.
