A more thorough explanation:

SUMMUM JUS

Summum jus is a Latin term that means "the highest law."

One example of summum jus is the Constitution of the United States. It is the highest law of the land and all other laws must comply with it.

Another example is the Universal Declaration of Human Rights. It is a set of principles that all countries should follow to ensure that human rights are protected.

Summum jus refers to the highest law, which means that it is the most important and powerful law in a given system. The examples illustrate this by showing how the Constitution and the Universal Declaration of Human Rights are both considered to be the highest laws in their respective contexts. All other laws must comply with these documents, and they are used to ensure that people's rights are protected and that the government operates fairly and justly.
