It may be that a monk has committed an offense. The Sangha, several monks, or a single monk accuses him, saying, ‘Venerable, do you remember committing such-and-such an offense?’ Although he’s sane, he acts insane, saying, This is allowable for me, and also for you.’ If the Sangha grants him resolution because of past insanity, then that granting is illegitimate. And what are the three legitimate grantings of resolution because of past insanity? It may be that a monk has been insane and suffering from psychosis.
