According to Buscetta: "It has never happened that a man of honor has gone to the boss of his family to inform him that he no longer wanes to belong to the Cosa Nostra. Circumstances can, for example, take the man of honor away from Sicily so that he is not used actively in the family's affairs; but at any time, and wherever he is, they may remember him and ask him to act in a way consistent with his being a man of honor, and he cannot refuse" (TB: III, 139).

DEFINE: Clarifies the Cosa Nostra's defining rule: membership is irrevocable and lifelong, even for men who relocate.
