Cristian d'Alessandro of Italy failed to get his criminal case closed due to the lack of an interpreter and will have to visit the St Petersburg branch of Russia's Investigative Committee again tomorrow, said Violetta Ryabko, a Greenpeace spokeswoman.
The criminal charges against the crew were closed under an amnesty that was passed by the parliament earlier this month, seen by many as an attempt by the Kremlin to dampen the criticism of Russia's human rights record before the Winter Olympics in Sochi in February.
The 30 crew members aboard a Greenpeace ship were detained in September and held in custody for two months before they were released on bail in November.
They were originally charged with piracy, but that was then downgraded to hooliganism.
"That was an extremely odd Christmas morning," Frank Hewetson of Britain was quoted by Grenpeace as saying today.
Peter Willcox, the US captain of the Greenpeace ship Arctic Sunrise, said in a statement released by the group that he was "pleased and relieved the charges have been dropped, but we should not have been charged at all."
He said earlier this month that he did not mind that charges against the Greenpeace team were dropped under the amnesty, but that he hoped that "this will not happen again.
