四分律刪繁補闕行事鈔 1.340

言惡馬治者。律云：若比丘犯罪，不問輕重，拒云不見，僧應棄捨莫問。語云：「汝所住處，亦當舉汝，為作自言，不聽汝布薩、自恣。如調馬師，惡馬難調，即合所繫杙棄之。汝比丘不自見罪，亦復如是，一切捨棄。」如是人不應從求聽；此即是聽，如法驅出。

Regarding the punishment of an intractable horse: The Vinaya states that if a bhikṣu commits an offense, regardless of whether it is light or heavy, and obstinately claims he does not see it, the saṃgha should abandon him and question him no further, saying to him: “Wherever you stay, we shall also censure you, record your own confession, and not permit you to perform the upoṣadha or pravāraṇā. Just as when a horse trainer encounters a vicious horse that is hard to tame, he pulls up the tethering peg and abandons it, so it is with you, bhikṣu: failing to see your own offense, you are completely abandoned in the same way.” Such a person should not seek permission [to participate]; this very [refusal of] permission is expulsion in accordance with the Dharma.
