Money paid with full knowledge of all material facts, under mistake of law, cannot be recovered in the absence of other reasons for allowing such recovery.1 The same principles apply where there is full knowledge of facts but one party subsequently wishes to avoid the transaction.2 Payments of this sort are merely examples, and the most common kind, of voluntary payments, and fall within the rule that voluntary payments cannot be recovered.
