On April 6, 2015, Caixin Weekly published an article that Hu Shuli, the editor-in-chief of Caixin, wrote. The title was, "The Promise to Resist Officials’ intervention in the Judiciary." The article discussed the new policy that the Office of the Chinese Communist Party Central Commission and the Office of the State of the People’s Republic of China issued and published on Xinhua on March 30, 2015.  The policy established a penalty, thereby preventing government officials from intervening in judicial activities and meddling with the judicial records of specific cases.
Hu pointed out in her article that Ma Jian, the former Deputy Minister of State Security, who used to support Guo Wengui (as discussed in previous ChinaScope briefings  ), has repeatedly intervened in criminal cases. Ma Jian was responsible to Zeng Qinghong, who was former leader Jiang Zemin’s top advisor. Hu Shuli stated, "Obviously, Ma’s purpose was to shelter their money-power trade network. However, a corrupt official whose rank and power was higher than Ma’s would have intervened more recklessly in the judicial system, and might even have done so in the name of strengthening the Party’s leadership over judicial work. Such acts have seriously damaged the judiciary, shaken citizens’ belief in the rule of law, and become the most dangerous viruses infecting China’s judicial system." 
The above-mentioned "higher-rank official" who "intervened more recklessly in the judicial system" "in the name of strengthening the Party’s leadership over judicial work" is likely to refer to Jiang Zemin, because he used that term, but his successors Hu Jintao and Xi Jinping did not.
