It may be that a monk has committed an offense entailing expulsion. The Sangha, several monks, or a single monk accuses him, saying, ‘Venerable, you’ve committed an offense entailing expulsion.’ He says, ‘I haven’t committed an offense entailing expulsion, but one entailing suspension.’ If the Sangha makes him act according to an offense entailing suspension, then that acting according to what’s been admitted is illegitimate.
