A law is a collection of rules or a standard that is made by a party or parties that have been given permission to do so by a governing body. The will of the people, who provide governmental organizations their authority to act, gives them the authority to make and enforce laws under the US democracy.
The social compact includes a principle. It is not a law; rather, it is the way that people behave in general as a result of societal standards. In some aspects, a principle represents the expectation of how one should behave even in the absence of legislation and may be seen of as a natural rule based on society standards.
