Supporters of Russian anti-corruption lawyer Sergei Magnitsky have seen their hopes of justice fade after it emerged that prosecutors have withdrawn charges against the only person to be tried in connection with his death.
An investigation into the death of Mr Magnitsky in Moscow's Butyrka prison in 2009 saw charges brought against two people, both doctors: Larisa Litvinova, who was responsible for the lawyer's treatment during the last weeks of his life, and Dmitri Kratov, who at the time was the chief medical official at the prison.
Charges of professional negligence against Dr Litvinova were dropped earlier this year after prosecutors claimed the statute of limitations had run out, and on Monday the state prosecutor, Konstantin Bokov, urged the court to acquit Dr Kratov. "There is no cause-and-effect relationship between Kratov's actions and Magnitsky's death," Mr Bokov is reported to have said. "I request his acquittal." The court is expected to make its ruling on Friday.
Mr Magnitsky died in November 2009 after nearly a year in jail – the victim, former colleagues say, of retribution from the same police investigators he had accused of stealing $230m from the state through fraudulent tax refunds. The 37-year-old's death was attributed by the prison to a heart attack, but Mr Magnitsky's supporters insist he was fatally beaten after exposing what he described as a web of corruption.
Relations between the US and Russia have deteriorated as a result of the case. Two weeks ago America passed into law its Magnitsky Act, which bans those linked to the lawyer's death from entering the US or using its banking system. The act prompted a furious response from the Russian Ministry of Foreign Affairs, which described it as "nothing but a vindictive desire to counter Russia in world affairs". In responseRussia's lower parliament, the Duma, has approved the so-called Yakovlev list, which among other things bars US citizens from adopting Russian children. The legislation is yet to be signed into law by President Putin.
"We have not determined what happened, and the biggest tragedy here is that... this may have been our last chance to ask questions," said Dmitry Kharitonov, a lawyer for Mr Magnitsky's widow Natalia Zharikova. Mr Kharitonov said a guilty verdict was possible but unlikely, adding: "The prosecutors essentially defended Kratov, rather than prosecuting him."
He said he believed prosecutors want Mr Kratov cleared to avoid any suggestion that they are culpable for Mr Magnitsky's death after they backed efforts to keep him in jail on tax evasion charges. He said he also believed they wanted to stay on the right side of the diplomatic argument. Calling for a further investigation into the case, he said: "The easiest thing for the prosecutor's office to do is to say that nobody is guilty – and if nobody is guilty, then why is the Magnitsky Act needed?"
Former Foreign Secretaries Sir Malcolm Rifkind and David Miliband have called for British Magnitsky Act to be introduced, complaining that corrupt officials enjoy their ill-gotten wealth in London with few consequences. President Vladimir Putin, who has dismissed suggestions Mr Magnitsky was killed, is under pressure not to adopt the Yakovlev List. More than 100,000 people have signed a petition organised by the liberal Moscow newspaper Novaya Gazeta calling for the law to be abandoned.
