“It was discovered that these organizations not only disseminated information that incited hatred and enmity against government officials, but also committed extremist actions,” a spokesman for prosecutors, Alexei Zhafyarov, said outside court.
A statement from the Moscow City Court after the 10-hour session said the offices of Navalny’s regional network and its anti-corruption organization had been banned with immediate effect.
The Navalny Anti-Corruption Foundation (FBK) has lobbied the Kremlin in recent years by publishing research on high-level corruption among the political elite.
Those investigations, in turn, have sparked massive street demonstrations.
Its network of regional offices has also promoted the 45-year-old opposition leader’s smart voting campaign, which encourages voters to vote for candidates in elections likely to oust pro-Kremlin rulers.
Wednesday’s ruling comes ahead of September’s parliamentary elections, in which the deeply unpopular ruling United Russia party is expected to fight.
Navalny, Putin’s most outspoken critic at home, survived a near-fatal nerve agent attack last summer that blames the Kremlin, a claim the administration denies.
Attorneys representing Navalny’s organization said Wednesday they had been given 10 days to appeal the ruling, which they said in an online statement they certainly would.
