Igor Sergunin was the only one of the three to plead guilty, according to independent sources, and received a lighter sentence of three and a half years.
Alyaksei Liptser received five years of imprisonment in a general regime colony, Vadim Kobzev – five and a half years.
Kobzev’s lawyer Andrei Hryvtsov said that the evidence against them constitutes illegal interference in private life.
“It is forbidden in principle to eavesdrop on meetings between the lawyer and the client in the colony – there is a direct legal prohibition,” he told the Russian BBC.
The three lawyers were tried near the Pokrov prison where Navalny was originally sent when he returned to Russia in January 2021 after surviving a nerve agent attack he blamed on Russian leader Vladimir Putin.
The Kremlin denied the allegations, and Navalny remained in the Russian colonies north of the Arctic Circle and 1,900 km (1,200 miles) northeast of Moscow until his death.
His widow, Yulia Navalnya, blamed Putin for his death, which the authorities are writing off as “sudden death syndrome.”
