Kelsen's Pure Theory of Law


In the realm of jurisprudence, numerous theories attempt to explain the nature and function of law. One captivating theory is Hans Kelsen’s Pure Theory of Law.

Afterwards, in this section i will discuss the foundation of legal systems, the basic norms and herarchy of norms in Kelsen’s Pure Theory of Law:

Foundation of Legal Systems in Kelsen’s Pure Theory of Law.

According to Kelsen, the foundation of legal systems lies in the notion of normativity. Norms are the fundamental building blocks of a legal system, representing the rules or principles that regulate human behavior within a society. Kelsen argues that legal norms are distinct from other types of norms (e.g., moral or social norms) and must be examined independently.

The Basic Norm in Kelsen’s Pure Theory of Law.

Albeit the core of Pure Theory of Law is the concept of the basic norm. This norm acts as the foundation upon which an entire legal system is constructed. The basic norm is a hypothetical construct, representing the highest level of legal validity within a legal system. It serves as the ultimate source of authority, providing the framework for all other norms to derive their validity.

Hierarchy of Norms

In Kelsen’s theory, legal norms form a hierarchical structure. Each norm derives its validity from a higher norm in the hierarchy until reaching the ultimate source of authority, the basic norm. This hierarchy ensures that the entire legal system is interdependent, with each norm deriving its legitimacy from the norm above it. This concept highlights the importance of understanding the relationship between norms within a legal system.

Separation of Law and Morality

One notable aspect Pure Theory of Law by kelson is his insistence on separating law from morality. Kelsen argues that law is a separate and autonomous discipline that should not be influenced by personal or subjective moral judgments. According to him, legal validity does not depend on the moral correctness of a norm, but rather on its relation to the basic norm within a particular legal system.

Criticisms and Legacy

in Conclusion The Pure Theory of Law has faced its fair share of criticisms over the years. Some argue that his theory oversimplifies the complexities of law, while others question the possibility of completely divorcing law from morality. Despite these criticisms, Kelsen’s theory has made a significant impact on legal philosophy and continues to shape legal scholarship to this day.


In General Theory of Law offers a distinctive perspective on the nature and structure of legal systems. By emphasizing the concept of normativity, the hierarchy of norms, and the separation of law and morality, Kelsen provides a framework for understanding the foundation of legal systems. While his theory has sparked debates and criticisms, it remains an essential contribution to legal philosophy. Understanding Kelsen’s Pure Theory of Law can deepen our comprehension of the complex dynamics within legal systems and the function of norms.
