The march, which police moved to break up before it even began, was intended as an expression of popular discontent with the government of President Vladimir Putin, and organizers claimed they were trying to use peaceful pressure to persuade the authorities to hold free and fair elections next year. In all, more than 100 anti-Kremlin protestors were rounded up.
"The complaint has just been filed," Karina Moskalenko told RIA Novosti. "In it we contend that a series of European human rights conventions were violated."
The former world chess champion, who founded his opposition party in 2005, was charged with organizing an unsanctioned demonstration, and a court later ordered him to pay a 1,000-ruble ($40) fine.
Moskalenko said that 10 others litigants had also joined the suit, adding that she expected more to follow.
She said that the detention had violated Kasparov's rights under Russian law to freedom of expression, freedom of assembly and access to a fair hearing.
