China has strengthened supervision over judicial personnel to prevent illicit activities, according to a report submitted to the top legislature.

Zhang Jun, procurator-general of the Supreme People's Procuratorate, made the report at the bi-monthly session of the Standing Committee of the National People's Congress on Wednesday.

The report said that since last year prosecutors had investigated 191 people suspected of deliberately making judgments contrary to facts and laws in civil or administrative trials.

The report said areas to be watched had been extended from judgment to the litigation process.

Over the past five years, 86,104 pieces of procuratorate advice have been made, concerning illicit acts in litigation, the report said. More than 90 percent were accepted by the courts.
