“When a monk has three qualities, the Sangha may, if it wishes, do a legal procedure of ejection against him for not giving up a bad view:

he’s quarrelsome, argumentative, and a creator of legal issues in the Sangha; he’s ignorant and incompetent, often committing offenses, and lacking in boundaries; he’s constantly and improperly socializing with householders. When a monk has another three qualities, the Sangha may, if it wishes, do a procedure of ejection against him for not giving up a bad view: he has failed in the higher morality; he has failed in the higher conduct; he has failed in the higher view. When a monk has another three qualities, the Sangha may, if it wishes, do a procedure of ejection against him for not giving up a bad view: he disparages the Buddha; he disparages the Teaching; he disparages the Sangha.
