Russia’s supreme court has overturned the conviction of peaceful dissident Ildar Dadin. The court ordered the 34-year-old immediately released from custody.

In 2015, Dadin was the first person to be convicted under strict new laws regulating anti-government demonstrations. Under the statute, violating protest rules more than twice in a 180-day period became a felony.

Dadin is well known as a supporter of Maidan revolution in Ukraine.
