The European Court of Human Rights ruled Thursday that Russian authorities' arrests of opposition leader Alexei Navalny were politically motivated, a decision that deals a blow to the Kremlin's dismissal of Navalny as a mere troublemaker.

Navalny hailed the ruling as an example of "genuine justice" and said it is an important signal for many people in Russia who face arbitrary detentions for their political activities.

The court's highest chamber found that Russian authorities violated multiple human rights in detaining Navalny seven times from 2012 to 2014, and that two of the arrests were expressly aimed at "suppressing political pluralism."

It ordered Russia to pay Navalny 63,000 euros ($71,000) in damages, and called on Russia to fix legislation to "take due regard of the fundamental importance of the right to peaceful assembly."

The ruling is final and binding on Russia as a member of the Council of Europe, the continent's human rights watchdog.

"I'm very pleased with this ruling — this is genuine justice," Navalny told reporters after the hearing. "This ruling is very important not only for me but also for many people in Russia who face similar arrests on a daily basis."

Russia is obliged to carry out the court's rulings, which enforce the European Convention on Human Rights , but it has delayed implementing past rulings from the court and argued against them as encroaching on Russian judicial sovereignty.

Navalny told reporters that he expects the Russian government to ignore this ruling and dismiss it on political grounds.

Navalny, arguably Russian President Vladimir Putin's most serious foe, has been convicted of fraud in two separate trials that have been widely viewed as political retribution for his investigations of official corruption and his leading role in staging anti-government protests.
