CHANGSHA, April 30 (Xinhua) -- The mother of a girl who was raped and forced into prostitution lodged an appeal on Tuesday in central China's Hunan Provincial High People's Court after losing a lawsuit she filed against local authorities who put her in a labor camp for protesting her daughter's captors' sentences.

Tang Hui appealed to have an April 12 judgment by the Intermediate People's Court of the city of Yongzhou overturned, as well as asked for an apology from the local re-education through labor commission and 2,463.85 yuan (399.5 U.S.dollars) in compensation for the time she spent in the labor camp.

Last year, Tang petitioned for harsher punishments for those found guilty of raping her daughter and forcing the girl into prostitution. She was put into a labor camp in Yongzhou for "seriously disturbing social order and exerting a negative impact on society" by protesting in front of local government buildings on Aug. 2, 2012.

She was sentenced to 18 months in the camp, but was released eight days later amid public outcry urging her release.

On Jan. 22, Tang filed a lawsuit at the Intermediate People's Court in Yongzhou in which she asked for 2,463.85 yuan in compensation, the same amount specified in her appeal. Her case was heard on Jan. 28, with courtroom proceedings lasting one day.

On April 12, the court ruled that Tang was not entitled to the compensation she requested.
