Deutsche Welle Dec. 18, 2020 Jailed Turkish philanthropist Osman Kavala is going on trial on charges connected with a failed 2016 coup. His yearslong imprisonment without a conviction has been condemned by rights groups across the world. Kavala has been in prison in Turkey for more than three years without being convicted of a crime Turkish civil society leader Osman Kavala is to appear on Friday before a court in Istanbul for a fresh trial seen by critics as part of a government campaign to crack down on dissent. Kavala, a 63-year-old businessman and philanthropist, who is known partly for his efforts to promote human rights through the arts, has been in prison in Turkey for more than three years without a conviction. His case has drawn condemnation from around the world, with the EU and US both calling for his immediate release. Kavala is the director of Turkey's Anadolu Kultur civil society organization and has supported a range of art and social projects. He was also a founding member of philanthropist George Soros' Open Society Foundation in Turkey. He was acquitted in February of attempting to overthrow the Turkish government during 2013 protests against the planned demolition of an Istanbul park that turned into anti-government rallies. However, he was rearrested almost immediately on fresh charges of espionage and trying to destroy the constitutional order in connection with a failed coup in July 2016. Quashing dissent In the aftermath of the coup, Turkish authorities have carried out a massive crackdown on suspected government opponents. Tens of thousands of judges, teachers, police and civil servants have been suspended or dismissed from their jobs, with many arrested and imprisoned. Human rights group say that Turkish President Recep Tayyip Erdogan has used the failed coup as a pretext to enact authoritarian policies. Turkey's constitutional court is currently deliberating on whether Kavala's detention is lawful. It is not known when it will deliver its verdict.
