Public Law is the study of the legal system of a country and how it operates within the
framework of government and society. The principles of Public Law are based on
constitutional, administrative, and criminal law. It plays a vital role in shaping the legal
framework of a country and is an essential component of the law curriculum in universities
around the world. This study document will explore the core concepts of Public Law,
including its history, principles, and application, providing a comprehensive understanding of
the subject.
History of Public Law
Public Law has its roots in ancient Greek and Roman law. The idea of a constitution, which
sets out the basic framework for government, was first developed in Greece. Rome took this
concept further by establishing a complex legal system that governed all aspects of public
life. The Magna Carta of 1215 in England marked a significant milestone in the development
of Public Law by establishing the principle that no one, not even the king, is above the law.
Principles of Public Law
The principles of Public Law are based on the idea that the state has a duty to protect its
citizens and promote their welfare. This involves establishing a legal system that ensures
justice, fairness, and the protection of individual rights. Public Law is divided into three main
categories: constitutional, administrative, and criminal law.
Constitutional Law
Constitutional Law is concerned with the fundamental principles that govern the relationship
between the state and its citizens. It sets out the basic framework for government and
establishes the rights and freedoms of individuals. Constitutional Law covers areas such as
the structure of government, the separation of powers, and the protection of individual rights.
Administrative Law
Administrative Law is concerned with the legal framework that governs the actions of
government agencies and officials. It regulates the way in which decisions are made, and
the procedures that must be followed when making those decisions. Administrative Law
covers areas such as judicial review, freedom of information, and the duty to provide reasons
for decisions.
