A more thorough explanation:

Definition: Contra bonos mores is a Latin term that means "against good morals." It refers to actions or contracts that are offensive to the conscience and sense of justice. Contracts that are contra bonos mores are voidable, meaning they can be cancelled or declared invalid.

Examples: Examples of actions that may be considered contra bonos mores include fraud, bribery, and other forms of corruption. Contracts that involve illegal activities, such as drug trafficking or prostitution, are also considered contra bonos mores and are not enforceable by law.

Explanation: The examples illustrate how actions or contracts that are considered immoral or illegal are not recognized by the law. This is because they go against the principles of justice and fairness that are essential to a functioning society. By declaring such actions or contracts voidable, the law seeks to discourage individuals from engaging in activities that are harmful to others and to the community as a whole.
