This monthly rotation system indicated that civil suits were accepted by the kita (north) office or by the minami (south) office alternatively, and ordinary jobs of the office except for the acceptance of civil suits (including criminal suits whose examinations were underway) were conducted naturally.
この月番制は、民事訴訟の受付を北と南で交替で受理していたことを指すものであり、民事訴訟の受理以外の通常業務（職権開始の刑事訴訟を含む）は当然行われていた。
