Case of Convict Zai Tudou's Assault in Xiaogu

During the Western Han Dynasty, Zai Tudou, a convict serving a sentence of "clamp and city-guard" (qian chengdan) in Xiaogu County, Dunhuang Commandery, engaged in a physical fight and injured another person. County Magistrate Yu and Assistant Shou investigated the incident and, following statutory procedures, prepared a legal report for higher authorities because the offender was already a penal laborer. The case was documented on bamboo slips, detailing the application of the Han Statutes and Ordinances to a serving prisoner who committed a new violent offense. The judicial authorities examined the nature of the injury and the offender's current penal status before determining the appropriate sentence. This case exemplifies how local Han officials handled crimes by convicts under state labor sentences.

The convict Zai Tudou received an aggravated sentence in accordance with Han law; given that standard assault with injury could result in additional hard labor or mutilation, his existing qian chengdan status likely led to an upgraded penalty, possibly a mutilating punishment such as amputation of the left foot.

Whether the penalty for a serving convict who committed a new assault should be aggravated beyond the standard punishment for "dou shang ren" (assault causing injury), and how to properly interpret the relevant statutes concerning recidivism while under penal labor.

The case provides rare direct evidence of Han Dynasty judicial procedure for prisoner recidivism, highlighting the strict legal attitude toward convicts who reoffend. It is a valuable primary source for studying the operation of the early Chinese penal system, the role of county magistrates in criminal adjudication, and the bureaucratic reporting requirements preserved in Dunhuang bamboo slip documents.
