“Ex dolo malo non oritur actio” is a Latin legal maxim that means “an action cannot arise from fraud.” This principle states that a person cannot file a legal claim based on their own fraudulent or wrongful conduct. Legal systems that adhere to this principle do not allow a party to seek legal remedies or benefits based on deceitful or wrongful behavior. This maxim is often linked to the broader legal principle that one cannot take advantage of their own wrongdoing to gain legal benefits or relief. It is a fundamental concept in many legal systems that helps to maintain the integrity and fairness of legal proceedings.
