Hans Kelsen (1881 - 1973) was an Austrian jurist, legal philosopher, and political theorist regarded as one of the most influential legal thinkers of the twentieth century. [1] He is best known for the Pure Theory of Law, an attempt to describe law as a self-contained system of norms free of moral, political, or sociological assumptions. [2] Kelsen was the principal architect of the Austrian Federal Constitution of 1920 and a founder of the model of centralized constitutional review adopted across much of Europe. [3]
Early life and education
Hans Kelsen was born on 11 October 1881 in Prague, then part of Austria-Hungary, into a German-speaking Jewish family that soon moved to Vienna. [1] He studied law at the University of Vienna, where he earned his doctorate in 1906 and later completed his habilitation. His early scholarship, including the 1911 study Hauptprobleme der Staatsrechtslehre, set out the foundations of the theory of law and the state that would occupy him for the rest of his career. [1]
The Pure Theory of Law
Kelsen's central contribution was the Pure Theory of Law, presented most fully in Reine Rechtslehre (1934) and its revised 1960 edition. [2] He sought to establish jurisprudence as a rigorous science by separating the description of legal norms from questions of morality, justice, and social fact. In his account, a legal system is a hierarchy of norms in which each norm draws its validity from a higher one, culminating in a presupposed basic norm, or Grundnorm, that grounds the system as a whole. [2] This framework became one of the most debated positions in modern legal positivism.
Constitutional work in Austria
Kelsen played a decisive role in shaping the constitutional order of the new Austrian republic after the First World War, drafting much of the Federal Constitution of 1920. [3] He championed the idea of a specialized constitutional court empowered to review the constitutionality of legislation, and he served as a judge on the Austrian Constitutional Court. This centralized model of judicial review influenced constitutional design throughout continental Europe. [3]
Emigration and later career
Political pressure and rising antisemitism led Kelsen to leave Austria, and he held professorships in Cologne, Geneva, and Prague before emigrating to the United States in 1940. [1] He taught at Harvard University and from 1945 at the University of California, Berkeley, where he broadened his work to include international law, sovereignty, and the theory of democracy. He remained in the United States until his death in Berkeley on 19 April 1973. [1]
Legacy
Kelsen's writings, translated into many languages, remain foundational to legal theory, constitutional law, and the philosophy of law. [2] His conception of centralized constitutional review is reflected in constitutional courts across Europe and beyond, and his native Vienna honored him with the Ring of Honour of the City. [1] The Hans Kelsen Institute in Vienna continues to publish and study his work. [3]
