What you suggest is certainly possible. It would take a team of lawyers to go over the fine print on the contracts.
I can't do that, and regretably, the press no longer does its job investigating this kind of story. The press should investigate, get copies of the contracts, consult their lawyers. But they probably won't bother to check who is telling the truth.
I doubt that such things are in so fine print. Probably it is enough to get the story from each side and compare. It should not be too hard.

I am sure there is plenty of sources available. Since we know the Ukrainian government side of the story, could someone provide the Russian explanation, preferably with some details and references?
