What were the three important principles of Roman law?

1) The principle of legal certainty: This principle holds that, to the greatest degree possible, laws must be written in such a way that they are clear and unambiguous, so that people may know what is, and is not, the law in all situations. This helps to give people trust in the legal system, resulting in greater compliance with the law. 2) The principle of equity: This principle holds that the application of the law should not be strictly applied. Instead, the judge should take into account the circumstances and context of the case and make rulings that are in the best interests of justice. This principle is also known as the principle of natural justice. 3) The principle of stare decisis: This principle holds that the decision of a court should govern how similar cases are decided in the future, thus promoting a consistent and predictable interpretation of the law. This principle also helps to give people trust in the legal system and greater compliance with the law.
