Dharmaguptaka-vinaya 17.29

17.29

爾時諸比丘，不知諍事如法滅、不如法滅，後乃知如法滅，或有作波逸提懺者、或有疑。佛言：「不知者無犯。自今已去當如是結戒：若比丘知諍事如法懺悔已，後更發起者，波逸提。」

At that time, bhikṣus did not know whether a dispute had been settled in a dharma-accordant manner or in an adharma manner, and only later came to know it had been settled in a dharma-accordant manner; some made confession of a pāyattika, and some had doubts. The Buddha said: "Those who do not know incur no āpatti. From this day forth, let the precept be laid down thus: 'If a bhikṣu knows that an adhikaraṇa has been settled in a dharma-accordant manner and confession made, and reopens it again, it is a pāyattika.'"
