At this time last year, newly appointed Communist Party leader Xi Jinping, who is now China's president, marked the anniversary of the constitution by pledging to uphold the rights of Chinese citizens and urging officials to build confidence in the law.
Xi's remarks last December prompted the country's liberal intellectuals, activists and others to advocate that China adopt constitutionalism in which the government's power is restricted by the country's laws.
The three Xinyu activists Liu Ping, Wei Zhongping and Li Sihua are among those who sought to push the party's new leadership to live by the promises laid out in the constitution, which guarantees freedoms of speech, assembly, religion and other rights that in reality are rarely protected in China.
The three are part of the New Citizens Movement, a loose network of campaigners who have lobbied for officials to declare their assets to help curb corruption. Participants have held small, peaceful demonstrations and organized dinner parties.
The three activists are accused of "illegal assembly" a charge their lawyers say stems from a photo of them holding signs calling for the release of other protesters and other charges.
A woman surnamed Peng who answered the phone at the Xinyu public security bureau said police had not received any reports of anyone being harassed at the courthouse.
