Chinese procuratorial agencies investigated 34,599 cases involving administrative litigation in 2015, up 1.6 percent from the year before, the Supreme People's Procuratorate (SPP) said on Tuesday.
According to a statement from the SPP, 4,033 of the 34,599 involved litigants appealing against judgments, while 1,081 of the filed cases were related to suspected illegal judging activity.
"Procuratorial agencies have intensified supervision efforts in administrative litigation in recent years," SPP spokesperson Xiao Wei said.
A revised Administrative Procedure Law took effect on May 1, 2015. The legislation, first promulgated in October 1990, guarantees citizens' rights to pursue the government through the courts.
The revision compels defendants -- representatives of the administrations concerned -- to personally appear at the court. Those who refuse to appear without legitimate reasons or who leave the court during the trial without approval may face additional punishment.
