The Ukrainian opposition demands parliament register two draft resolutions on the procedure to return the 2004 Constitution and to vote on them on February 20, leader of the Batkivschyna faction Arseniy Yatseniuk said.

"We demand that our draft resolutions be registered, be included on the agenda tomorrow and pass relevant field-specific committees on Wednesday [February 19] and that we put for vote on Thursday [February 20] two our acts - the constitution act which was submitted today with signatures of over 200 people's deputies and the resolution of the Ukrainian Verkhovna Rada of the 1996 version of the Constitution - so that the Ukrainian people can see who votes in which way and which party supports what," Yatseniuk said during a meeting of the coordination board of factions and parliamentary committee heads in Kyiv on Monday.

The administration in parliament refuses to register these documents, Yatseniuk said.

The Verkhovna Rada resolution on the 1996 Constitution stipulates all the facts on passing rulings by the Constitutional Court, Yatseniuk said.

The Constitutional Court does not have the right to reconsider the Constitution and the 2010 rulings of the Constitutional Court were corrupt, Yatseniuk said.

"Submitting amendments and annexes to the Constitution should be held in accordance with the Ukrainian Constitution," Yatseniuk said.
