Calumny is any form of ruse or fraud used to deceive another, particularly in judicial proceedings. It means the unjust damaging of the good name of another by putting a crime or fault of which he is not guilty upon him. The sin, thus is committed in a general sense, mortal. Objectively, a calumny is a mortal sin when it is calculated to do serious harm to the person wrongly accused. Just as in the instance of wrongful damage to a person or estate, so the calumniator is bound to adequate payment for the injury perpetrated by the blackening of another's good name. He is obliged to: (1) to retract his false statements, and that even though his own payments may necessarily as a consequence suffer. (2) He must also make good whatever other losses have been sustained by the innocent party as a result of his utterances, provided these same have been in some measure foreseen by him.
