BEIJING, Feb. 1 -- Chinese courts handled more than 13.37 million cases in 2013, up 6.8 percent year on year, the Supreme People's Court (SPC) said Saturday in a statement.

Courts at all levels closed more than 12.94 million cases, including a number of major ones, such as the trials of former secretary of the Chongqing Municipal Committee of the Communist Party of China Bo Xilai and former railways minister Liu Zhijun, it said.

According to the SPC, 1,960 cases that had not been concluded for more than three years were completed last year.

Several wrong judgements were corrected in 2013, including the case of Li Huailiang who was wrongly detained and jailed over 12 years for the rape and murder of a teenage girl in central China's Henan Province.

The SPC also issued a series of judicial interpretations concerning food safety and creating and spreading online rumors.
