Yes, they did. The both sides used such a 'vote'.
BTW, it is quite ironic to complain about legal procedures in that part of the world (Russia and Ukraine) where such a saying is quite common: Everything - for my friends; the law - for my enemies.
People forget the agreement between Yanukovych and the Maidan leadership all supervised by the EU and Russia, that deal was signed on the 21st of feb 2014, it just about gave the Maidan lot everything they wanted but Yarosh the right sector Nazis didn't like it so some people didn't want that deal to go through, and we know who they were, the deal was signed in the morning by afternoon the Nazi element had taken control of all the Government b
21 February, Parliament passed a peace agreement signed by President Yanukovych and all three opposition leaders that: ordered the withdrawal of troops and banned the use of lethal force; stated that only Parliament could declare a state of emergency; mandated early Presidential elections after the reinstatement of the 2004 Constitution; and declared that antigovernment forces must forfeit any weapons and relinquish control over public buildings.
Parliament then passed a series of resolutions to implement and expand the peace deal, including blanket amnesty for antigovernment protesters and a bill to free former prime minister Yulia Tymoshenko from prison.
Later a column of 40 policemen from Lviv arrived in Kiev to declare their defection from the government and their intent to protect the demonstrators.
All security forces had withdrawn from Independence Square by the afternoon.
At the Maidan many activists, including members of Right Sector and Automaidan, denounced the deal as an unacceptable compromise and continued to demand Yanukovych’s resignation. As the opposition leaders spoke, demonstrators held an open casket procession for protesters who had died in the previous days, marching forward to lay the coffins on the stage.
Leaders of two militant nationalist groups interrupted the speeches, blamed the opposition leaders’ for failing to oust Yanukovych and vowed to lead an armed attack.
Late that evening, President Yanukovych fled the capital.
The next morning, 22 February, given the continued absence of riot police, occupiers of the Maidan declared themselves the head of security for Kiev. The presidential administration building near Independence Square remained empty. Protesters carrying makeshift weapons seized Yanukovych’s palace near Kiev and opened it to the public.
In the afternoon President Yanukovych spoke on television from eastern Ukraine, stating that a “coup” had driven him from the capital but he had no plan to resign. Few major institutions in Ukraine still remained under the control of Yanukovych’s administration.
Parliament acted the following day, the 23rd, making Oleksandr Turchynov the new president pending an election, and ousting remaining members of Yanukovych’s cabinet. Members of Yanukovych’s own party issued a statement strongly denouncing the now-deposed President’s use of deadly force against protesters. The military declared support for the new government.
Pro-Yanukovych demonstrators held rallies in several eastern cities.
uildings the police had already withdrawn from the streets, bottom line is it was a coup.
