A more thorough explanation:

Definition: Ex dolo malo is a Latin term that means "out of fraud" or "out of deceitful or tortious conduct."

Example: If a person sells a car to another person, knowing that the car has a serious mechanical problem, and does not disclose this information to the buyer, the sale is considered ex dolo malo.

Explanation: In this example, the seller is engaging in deceitful conduct by not disclosing the mechanical problem with the car. The buyer is being defrauded because they are not aware of the issue and are purchasing a faulty car. This is an example of ex dolo malo because the sale is being made out of fraudulent behavior.
