Nemtsov and Milov have been banned from leaving Russia for six months:

source They lost a defamation case brought by Gennady Timchenko, the owner of Gunvor, whom they had accused of something everyone already knows: that he is a friend of V.V. Putin and has built his business on that friendship. Nemtsov and Milov were ordered to publish a retraction, which they did. However, Timchenko's lawyer decided that the retraction was not done properly and demanded that the defendants be barred from leaving Russia. And the bailiff service was only too happy to do exactly that. Quite an interesting situation.

Timchenko is a Finnish citizen. He has officially renounced his Russian citizenship. He lives in Switzerland, in the canton of Zug, which allows him to minimize his tax burden. He makes his money by latching onto Russian oil like a parasite, like a leech. His crony and accomplice, citizen V.V. Putin, simply forced the largest oil companies to trade through him. Timchenko, who gave up Russian citizenship and pays taxes outside Russia, is the biggest trader of our oil and has officially become a billionaire because of it. Everyone knows this. But if you say it out loud, a Russian court will declare that you are damaging the reputation of the wonderful Mr. Timchenko, and the Russian bailiff service will bar you from leaving the country. It brings to mind stories about He-Who-Must-Not-Be-Named. And here is another story about the enforcement of court rulings: I won cases against Rosneft and Transneft in two levels of court. The rulings came into force back in April. Did I get the documents? Of course not. In fact, enforcement proceedings against Transneft have even been opened:

As you can see, the deadline for complying with the ruling has been missed, and Transneft should already have been fined (5,000 rubles, about $50 at the time—not exactly a terrifying coercive measure). Unfortunately, under current law I cannot demand that Transneft chief Tokarev be barred from leaving Russia. A pity—it would be wonderful to ruin his summer vacation in some French château. Even so, failure to comply with a court ruling is, at least in theory, punishable here even by criminal liability. Let's see whether the bailiffs will defend the interests of Russian citizen Navalny as zealously as they defend those of Finnish billionaire Timchenko.
