[467] Now at that time the group-of-six bhikkhus, thinking, "No one knows about us," listened to the Pātimokkha even while having offenses (āpatti) upon them. Elder bhikkhus who knew the minds of others informed the bhikkhus: "Friends, the group-of-six bhikkhus named so-and-so and so-and-so, thinking, 'No one knows about us,' listen to the Pātimokkha even while having offenses upon them."
The group-of-six bhikkhus heard: "It seems the elder bhikkhus who know the minds of others are informing the bhikkhus about us: 'Friends, the group-of-six bhikkhus named so-and-so and so-and-so, thinking, "No one knows about us," listen to the Pātimokkha even while having offenses upon them.'" Thinking, "The well-behaved bhikkhus will suspend the Pātimokkha against us first," they preemptively suspended the Pātimokkha against pure bhikkhus who were without offense, without any matter, without any reason.
Those bhikkhus who were of few wishes … criticized, denounced, and spread it about: "How can the group-of-six bhikkhus suspend the Pātimokkha against pure bhikkhus who are without offense, without any matter, without any reason?" Then those bhikkhus reported this matter to the Blessed One. … "Is it true, bhikkhus, as they say, that the group-of-six bhikkhus suspend the Pātimokkha against pure bhikkhus who are without offense, without any matter, without any reason?" "It is true, Blessed One." … Having rebuked them and given a talk on the Dhamma, he addressed the bhikkhus: "Bhikkhus, the Pātimokkha is not to be suspended against pure bhikkhus who are without offense, without any matter, without any reason. Whoever should suspend it commits an offense of wrong-doing (dukkaṭa)."
