The process of globalization increasingly intertwines the legal systems of all nations, making an understanding of our differences and similarities a useful, if not essential, tool for working across borders. In the West, there are two predominant legal cultures, common law and civil law. While vast differences are often presumed, even a basic understanding of both legal traditions reveals a striking number of points of convergence, and even where differences remain, an introductory vocabulary regarding the two is sufficient for meaningful discourse among assistance providers and counterparts that have been raised in differing legal cultures. Here, New-Rule explains key elements of the two systems. While other legal traditions are increasingly relevant to ROL activities, e.g., shari’a law, a discussion of the full range of traditions is beyond the scope of this basic webpage. New-Rule anticipates others to be forthcoming. Our mantra is to push knowledge to the forefront. Share and challenge to exceed is our approach.
