sailors. June 20, 2009 – In Sevastopol, a Russian fleet servicemen allegedly used physical force against 30 civilians. The city also alleges contract violations by the Construction Management Corporation of the Black Sea Fleet for not following through on promises to construct requested commercial housing after taking advance payment. The city began talks with the President and the Prime-Minister of the Russian Federation, Dmitry Medvedev and Vladimir Putin, and also to the Russian Minister of Defense Anatoliy Serdyukov with respect to the contract violations, but those did not yield results. On August 27, 2009, Russian marines successfully prevented Ukrainian bailiffs from enforcing a Ukrainian court ruling on seizing lighthouses belonging to the BSF. Russia stated that Ukrainians may not step onto its bases without permission. The Ukrainian Foreign Ministry described the Russian obstruction as a "disregard for Ukrainian legislation and international agreements". On April 16, 2013, a "high-ranking Russian Defense Ministry official" complained to Interfax that "Ukraine's stubborn position" was slowing the cancellation of customs payments (for the fleet) and that Ukraine still upheld (former) Ukrainian President Viktor Yushchenko's 2008 decrees that banned the "relaxed procedure" of BSF formations crossing the Ukrainian border.
