The precursor to the CCEG was the Special Case Examination Committee, an organ established by the Politburo in May 1966 to investigate the political offences of Peng Zhen, Luo Ruiqing, Lu Dingyi and Yang Shangkun. When it was found that there was a need for analysis of other cases, the committee was retained under a new name, and soon achieved a permanence as a central institution.
