Case of Yuan, Man, and Jin for Not Knowing the Yue Rebellion

Around 112 BC, during the reign of Emperor Wu of Han, the kingdom of Nanyue revolted against imperial authority. Three local administrators—Yuan, Man, and Jin—were accused of “not knowing the Yue people were plotting rebellion” (弗知越人反). Under the draconian laws promoted by Emperor Wu and his harsh legalist advisors, failure to detect and report a rebellion was treated as an offense equivalent to complicity, with strict liability regardless of actual knowledge. The three were arrested, tried before the Commandant of Justice, and convicted. Despite their lack of forewarning or participation, they were sentenced to death by public execution (弃市). This case, preserved in the “Discourses on Salt and Iron,” exemplifies the era's excessively punitive legal net. It was later cited by Confucian literati as a brutal illustration of the arbitrary and inhumane application of capital punishment under an autocratic regime.

Yuan, Man, and Jin were found guilty and executed by public beheading (弃市), a common death penalty for serious crimes in the Han Dynasty.

Whether ignorance of a rebellion should be punished as a capital crime, and whether the law should impose strict objective liability without proving actual knowledge or criminal intent, highlighting the conflict between Legalist absolutism and Confucian principles of proportionality and moral culpability.

The case became a notorious symbol of oppressive legalism under Emperor Wu. It was fiercely criticized during the Salt and Iron Debates by reformist scholars, who used it to denounce the cruelty of the era's penal system. The precedent fueled enduring debates on collective punishment, strict liability, and the necessity of mens rea in traditional Chinese law.
