A Moscow prosecutor has demanded prison terms of between five and six years for eight demonstrators charged with mass disorder at a protest held in May 2012 on the Russian capital's Bolotnaya Square.
The hearings were adjourned until January 27.
Several dozen people were arrested on Bolotnaya after a protest against President Vladmir Putin's third term in office.
The protest ended in clashes, with scores of police and protesters injured.
Twenty-eight protesters were charged with organizing or participating in mass disorders.
Three have already been convicted and sentenced to 2 1/2 and 4 1/2 years in jail, while one was sent to a psychiatric clinic.
In December, criminal proceedings against four protesters were dropped following an amnesty signed by Putin.
Activists say the clashes on Bolotnaya were planned provocations by authorities.
Investigators say the protest was orchestrated by a Georgian politician.
