The court on Tuesday said Navalny's 30-day sentence would come into effect immediately, a Reuters correspondent there reported.
"What happens in court really has no relation to the judgment, the judgment probably already exists. they need to observe some formal steps but it has no relation to the result", Navalny told reporters following the adjournment.
Navalny had called for demonstrations in more than 90 towns and cities under the slogan "Putin is not our tsar" to protest what he says is Putin's autocratic rule.
The jail sentence could reflect the authorities' desire to keep Navalny behind bars to prevent him from staging more protests in the run-up to the World Cup hosted by Russian Federation that could tarnish its opening on June 14.

"Hamas is intentionally and cynically provoking this response", Shah said , noting that Israel "has the right to defend itself". Merkel also expressed concern at the violence in Gaza , but said " Germany understands Israel's security needs".
Navalny himself was grabbed by police and carried away by his arms and legs shortly after appearing in Moscow's packed Pushkin square.
Navalny had previously been detained in January after joining a rally calling for a boycott of the presidential election. Separately, he was also convicted of disobeying police during the rally and sentenced to 15 days, but that sentence would be counted as part of the 30 days under Russian law.
"I consider the detention was illegal, my rights were violated", Navalny said in court, arguing he had a constitutional right to hold a protest. "On the basis of provisions of the Russian Code on Administrative Offences and the Supreme Court's clarifications, the enforcement of arrest begins on the day the relevant ruling is handed down".
