In page Gustav Radbruch:

"

The core of Radbruch's legal philosophy consists of his tenets the concept of law and the idea of law. The idea of law is defined through a triad of justice, utility and certainty. Radbruch thereby had the idea of utility or usefulness spring forth from an analysis of the idea of justice. Upon this notion was based the Radbruch formula, which is still vigorously debated today. The concept of law, for Radbruch, is "nothing other than the given fact, which has the sense to serve the idea of law".[citation needed]
