Explanation: The term ‘justice’ in the Preamble embraces three distinct forms– social, economic and political, secured through various provisions of Fundamental Rights and Directive Principles.

• Social justice denotes the equal treatment of all citizens without any social distinction based on caste, colour, race, religion, sex and so on.
• It means absence of privileges being extended to any section of the society, and improvement in the conditions of backward classes (SCs, STs and OBCs) and women.
• Economic justice denotes the non-discrimination between people on the basis of economic factors. It involves the elimination of glaring inequalities in wealth, income and property.
• A combination of social justice and economic justice denotes what is known as ‘distributive justice’.
• Political justice implies that all citizens should have equal political rights, equal access to all political offices and an equal voice in the government.
• The ideal of justice–social, economic and political–has been taken from the Russian Revolution (1917).
