Important Points

Key features of the Indian Constitution:

• Federalism:
  • This refers to the existence of more than one level of government in the country.
  • In India, we have governments at the state level, at the centre and Panchayati Raj at the village level.
  • The Constitution contains lists that detail the issues that each tier of government can make laws on.
  • In addition, the Constitution also specifies where each tier of government can get the money from, for the work that it does.
  • All persons in India are governed by laws and policies made by each of these levels of government.
• Parliamentary form of government:
  • The people of India have a direct role in electing their representatives. Also, every citizen of the country, irrespective of his/her social background, can contest in elections.
• Separation of powers:
  • There are 3 organs of government:
    • The legislature: refers to elected representatives by the people.
    • The executive: is a smaller group of people who are responsible for implementing laws and running the government.
    • The judiciary: refers to the system of courts in India.
  • Each organ mentioned above acts as a check on the other organs of government. This ensures the balance of power between all three.
• Fundamental rights:
  • The constitution guarantees the rights of individuals against the State as well as against other individuals. It also guarantees the rights of minorities against the majority.

    • Right to Equality
    • Right to Freedom
    • Right against Exploitation
    • Right to Freedom of Religion
    • Cultural and Educational Rights
