Egyptian prominent activist Alaa Abdel-Fatah and 24 co-defendants will stand trial on 23 March.
They all face charges of illegal protesting.
The court decision comes after several protests against the detention of activists for months with no trial.
Abdel-Fatah has spent over 100 days in detention without trial since he was arrested last November.
On 26 November, Abdel-Fattah, along with other activists, organised a protest in central Cairo to denounce the subjection of civilians to military trials. The protest was dispersed by police, and scores of activists were arrested.
Abdel-Fattah was arrested at his home on 28 November, two days after the protest.
In January, he received a suspended one-year jail sentence in a separate case on charges of torching the campaign headquarters of Hosni Mubarak's last prime minister Ahmed Shafiq who ran for president in 2012.
