Australian Colin Russell is now the only one of the 28 activists and two journalists who were arrested over an Arctic drilling protest in September to remain without bail.
On Friday, Russian courts granted bail to Briton Phil Ball, Swedish-US joint citizen Dima Litvinov and Russian Roman Dolgov, all three joining 26 others who were bailed in the past week.
It remains unclear why Russell’s appeal was the only one to be turned down at the second time of asking.
Most of those bailed have already left prison, but it is understood they have not yet received their passports and are not free to leave Russia.
All 30 were arrested on board Greenpeace’s flagship vessel Arctic Sunrise during a failed attempt to scale a Gazprom Neft Shelf-operated platform in the Pechora Sea in September.
They all still face charges of hooliganism that carry a prison sentence of up to seven years.
An international tribunal on Friday also ordered Russia to release the Arctic Sunrise on payment of a €3.6 million ($4.87 million) bond.
