Abstract: This article explores the reasons why the Board of Punishment，as the judicial and legal center“Under Heaven，”adjudicated numerous minor cases during the Qing dynasty. The Board of Punishment adjudicated minor cases because of the special jurisdiction over bannermen，especially the imperial clansman and because of the inherent contradiction of the juridical system in the Capital. At the beginning of the Qing dynasty，because of the special jurisdiction over bannermen，the Imperial Household Department and the Eight Banners had to send cases involving both bannermen and civilians to the Board of Punishment. Censors of the Five Wards also had to send cases involving only bannermen to the Board. Since the mid-Qing，cases involving imperial clansmen，regardless of their possible punishments，had to be co-adjudicated by both the Imperial Clan Court and either the Board of Revenue or the Board of Punishment. There was not“a system of adjudicating，transmitting，and confirming level by level”in the Capital，and each yamen did not offer recommended punishments when they sent cases to the Board of Punishment. Therefore，the Board adjudicated numerous minor cases in order to avoid delay.
