Jailed Russian opposition leader Alexei Navalny appeared before a Supreme Court judge by video link on January 11 to argue for the right to longer meal breaks and access to more books in prison.Wearing a black prison uniform and standing behind bars in a small, bare room, Navalny, 47, appeared gaunt but spoke animatedly, at length and without notes.It was the second day running that he had taken part in legal hearings from the Arctic “Polar Wolf” penal colony, one of Russia’s harshest, to which he was transferred last month after his cumulative sentences were extended to more than 30 years.Navalny said prison rules limiting inmates to one book at a time meant that someone who chose to have a Bible or a Koran could not have any other religious or secular literature, including newspapers or magazines.”One book is not enough for me. It clearly violates my religious rights,” he said.He also argued that meal breaks were too short.His arguments prompted a detailed discussion with the judge and a representative of the justice ministry on prison libraries, meal arrangements and cell furnishings.Navalny has frequently used such hearings in the past as a means of defying the authorities, demonstrating his resilience and maintaining a link to the outside world despite the harsh conditions of his imprisonment.He and his supporters say the many charges against him, ranging from fraud to extremism, were trumped up to silence his criticism of President Vladimir Putin.The Kremlin makes a point of not speaking his name and says he is a convicted criminal whose treatment is a matter for the prison system.
