A more thorough explanation:

LEGES ET CONSUETUDINES REGNI

Leges et consuetudines regni is a Latin term that means "laws and customs of the kingdom." It refers to the common law, which is the body of law that is based on customs and judicial decisions rather than on written laws.

One example of leges et consuetudines regni is the principle of stare decisis, which means "to stand by things decided." This principle requires judges to follow the decisions of higher courts in similar cases. Another example is the presumption of innocence, which means that a person is considered innocent until proven guilty.

For instance, if a judge is deciding a case and there is a previous case with similar facts and issues, the judge will look to the decision in that previous case and follow it. This is an example of the principle of stare decisis, which is part of the common law.

Similarly, if a person is accused of a crime, they are presumed innocent until the prosecution proves their guilt beyond a reasonable doubt. This is an example of the presumption of innocence, which is also part of the common law.

Leges et consuetudines regni is a term that refers to the common law, which is a system of law that is based on customs and judicial decisions. The examples of stare decisis and the presumption of innocence illustrate how the common law works in practice. Stare decisis requires judges to follow previous decisions in similar cases, which helps to ensure consistency and predictability in the law. The presumption of innocence is a fundamental principle of criminal law that protects the rights of the accused and ensures that the prosecution bears the burden of proving guilt.
