From Latin cui est bono? (“to whom is it a benefit?”).
- The principle that the ultimate initiator of an action is likely the person who stands to gain from the action.
- 1900, Evelyn Shuckburgh, Letters to Atticus, translation of original by Marcus Tullius Cicero:
- If the principle of cui bono is applied, it is evident that the gainers were the party of the trumvirs, whose popularity would be increased by a belief being created that their opponents the Optimates were prepared to adopt extreme measures to get rid of them.
