Turkey’s Constitutional Court ruled on Tuesday that prominent philanthropist and businessman Osman Kavala’s detention did not violate his right to liberty and security, state news agency Anadolu reported.
The country’s top court rejected Kavala’s individual application by eight votes against seven, according to Anadolu.
Kavala, who has been jailed since November 2017, has to remain behind bars.
Kavala was acquitted in February in a trial in connection with the 2013 Gezi Park environmental protests in Istanbul.
However, before he could walk free, a new warrant was issued for Kavala on charges linked to an attempted coup in 2016.
An Istanbul court earlier this month started the new trial in which Kavala could face life imprisonment if found guilty of attempting to overthrow the constitutional order and up to 20 years for espionage.
Kavala, the chair of Anadolu Kultur, which also works with the Goethe Institute, denies all charges.
