"Finally, the constitution demands that at least three quarters of the constitutional membership of the Verkhovna Rada vote for the removal of the President in the final step. However, instead of the required 338 parliamentary deputies only 328 voted for the removal of the President." [0]
The internationally accepted standard is 2/3. Not a single country besides Russia recognized Yanukovych as the president of Ukraine after the vote, and even Russia gave up being a sore loser after a few months.
No I don't. If you want to nitpick, then for starters the Ukrainian parliament didn't go through the formal impeachment process (which requires 4/5 majority), because the Ukrainian constitution has no provisions for a situation when president and cabinet ministers just burn documents to hide tracks, run away into another country and become internationally wanted criminals.
Instead, the parliament passed a declaration saying that the government had abadoned their duties and called for early elections, and did so within the bounds of Ukrainian laws, and with an internationally recognized margin of majority for such drastic steps. There is no domestic or international case for calling early elections a coup. The whole "coup" sob story has been dead and buried for a long time. The transition of power was as clean as you can hope to get in a severe political crisis.
If you are looking for something to call a coup, then the Russian invasion of Crimea was a textbook coup.
