Introduction to Law

LAW RAS Mains 2018

The idea of ‘Law’ as guide to human conduct is as old as the existence of the civilized society. However, the concept of law is not static. With the changes in the society, the concept of justice changes and accordingly laws also change. Justice & correspondingly ‘law’ is an evolutionary concept.

Justice & Law:

Justice and law are closely inter-related. Law acts as means of serving Justice. Bentham argues that purpose of Law is Justice and without an element of justice, Law becomes an instrument of oppression. In the legal sense, justice is process of application of law to particular cases.

Though law and justice are intimately connected with each other, there is difference between the two. Law seeks to give justice, but law is not justice. The modern courts of law provide legal and not moral justice.

Definition of Law:

As the meaning of justice changes from time to time, society to society. Law can be defined by its basis (nature, reason, religion or ethics), by its sources (customs, legislation), by its effect on the life of the society and by the ends that it seeks to achieve. Hence, there in no Universal definition of Law. However, some of the important definitions of Law given by various thinkers:

  • Aristotle:
    • Perfect law is inherent in the nature of man/woman and can be discovered through reason. It is immutable, universal and capable of growth.
  • Austin:
    • “Law is the command of Sovereign.”
  • A. V. Dicey
  • “Law is the reflection of Public opinion.”
  • Salmond
    • “Law is body of Principles recognised and applied by the State in the Administration of Justice”
  • Roscoe Pound
    • “Law is a social control through systematic application of force in a politically organised society?” An instrument to satisfy the maximum wants in a society with the minimum of friction and waste.
