What is one way to think about how it is possible that principles written in magna carta almost 800 years ago are still valid today? the concept of jurisdiction means that anything signed by the king of england was a fundamental human right because kings have control over the entire territory. the concept of rule under law means that everyone must follow the will of the king or the person or group that is the leader of the country. the concept of civil law means that writing down a law means that it is fair and just and does not violate the rights of individuals. the concept of precedent means that over the years, individuals in england interpreted the document to continue to protect the rights described in the document. the concept of constitutional law means that any legal document is valid forever.
