Concept:
The theory of "Grundnorm" is a fundamental concept in legal theory introduced under the Pure Theory of Law. It refers to the basic norm or foundational rule from which all other legal norms derive their validity.
Step 1: Understanding Grundnorm.
"Grundnorm" means "basic norm." It is a hypothetical rule that serves as the ultimate source of validity for a legal system.
Step 2: Identifying the propounder.
Hans Kelsen, an Austrian jurist, developed the Pure Theory of Law and introduced the concept of Grundnorm as the foundation of a legal system.
Step 3: Eliminating other options.
- John Austin: Known for the Command Theory of Law
- H.L.A. Hart: Known for the Concept of Law and Rule of Recognition
- Roscoe Pound: Known for Sociological Jurisprudence
Thus, only Hans Kelsen is associated with the theory of Grundnorm.
