Before dawn on Feb. 27, at least two dozen heavily armed men stormed the Crimean parliament building and the nearby headquarters of the regional government, bringing with them a cache of assault rifles and rocket propelled grenades. A few hours later, Aksyonov walked into the parliament and, after a brief round of talks with the gunmen, began to gather a quorum of the chamber's lawmakers.

Спустя 22 года и 364 дня после первого в СССР референдума в автономной республике Украины Крым состоялся последний референдум. Проводился он вопреки украинскому законодательству, не предусматривающему понятия региональный референдум и предписывающему решать территориальные вопросы только на всеукраинском референдуме

Zeitschrift für ausländisches öffentliches Recht und Völkerrecht (Heidelberg Journal of International Law). 2014, 74 [2022-03-04]. （原始内容(PDF)存档于2020-01-01）. Organizing and holding the referendum on Crimea's accession to Russia was illegal under the Ukrainian constitution. Article 2 of the constitution establishes that "Ukraine shall be a unitary state" and that the "territory of Ukraine within its present border is indivisible and inviolable". This is confirmed in regard to Crimea by Chapter X of the constitution, which provides for the autonomous status of Crimea. Article 134 sets forth that Crimea is an "inseparable constituent part of Ukraine". The autonomous status provides Crimea with a certain set of authorities and allows, inter alia, to hold referendums. These rights are, however, limited to local matters. The constitution makes clear that alterations to the territory of Ukraine require an all-Ukrainian referendum.

The recognition of Crimea by Russia was the legal fig leaf which allowed Russia to say that it did not annex Crimea from Ukraine, rather the Republic of Crimea exercised its sovereign powers in seeking a merge with Russia
