Tang Hui had been sentenced without trial to 18 months in a labor camp in August 2012 for "disturbing social order" after she demonstrated for stricter punishment of those found guilty of raping her then 11-year-old daughter and forcing her into prostitution, China's official Xinhua news agency reported Wednesday.
A public outcry forced officials to release Tang eight days later.
In her complaint filed with the Intermediate People's Court in Yongzhou, Tang demanded $235 in compensation from the camp for infringing on her personal freedom, another $160 for psychological damage and a written apology.
She also asked for a change of venue so Yongzhou authorities could not interfere with the outcome of the case.
