Cosa Nostra cartels rotate leadership to prevent power imbalances [fact]
In order to prevent a potential imbalance of power, some other prominent member was appointed instead (TB: I, 102; III, 23; AC: I, 6, 122). Finally, at the head of the commissione would be a rappresentante regionale or segretario, essentially the first among equals (a description used by Calderone himself; AC: I, 8). He was a weak leader, especially in the earliest incarnation of the cartel, his task simply that of organizing meetings (TB-GdS, April 4, 1986).
XREF: Connects to literature on organized crime leadership structures and how criminal organizations deliberately engineer weak central authority to preserve member autonomy.
