How UPPSC frames this topic

The syllabus line covers historical underpinnings, evolution, features, amendments, significant provisions and basic structure, and the role of the Supreme Court in the evolution of its basic provisions. Prelims facts ask for parts, lists and provisions. Mains angles ask to discuss features, federal balance and judicial role.

Typical directive words are discuss, examine and evaluate. Link each feature to a provision and to the institution that works it. Read it with the UPPSC syllabus notes and the basic structure doctrine and the Supreme Court.

What are the key features of the Constitution?

Features can be grouped under four heads for easy revision: the nature of the State, the rights of the citizen, the distribution of power and the independent judiciary. Each head connects to Parts and provisions listed later in these notes, so read the sections together.

The Constitution establishes India as a Sovereign Socialist Secular Democratic Republic with a Parliamentary form of Government. It is the supreme legal authority that binds the legislative, executive and judicial organs.

Key features and where they sit
Feature What it means
Fundamental Rights Guaranteed to all citizens; Part III
Judicial review Courts can strike down laws that violate it
Federal system Powers divided between the Union and the States
Separation of powers Three organs of government
Free and fair elections Part XV deals with elections
Secular state Recognises freedom of conscience and religion

The Preamble resolves to secure justice, liberty, equality and fraternity for all citizens.

How is the Constitution organised?

A simple way to learn the layout is to move from the State to the citizen to the government. Parts I and II deal with the territory and citizenship. Parts III to IVA deal with rights, directive principles and duties. Parts V and VI deal with the Union and the States. Later Parts cover local bodies, relations between the Union and the States, elections, emergency and amendment.

The text is arranged in Parts. The table lists some of the Parts that students must place correctly.

Selected Parts of the Constitution
Part Subject
Part I The Union and its territory
Part II Citizenship
Part III Fundamental Rights
Part IV Directive Principles of State Policy
Part IVA Fundamental Duties
Part V The Union
Part VI The States
Part IX The Panchayats
Part IXA The Municipalities
Part XVIII Emergency Provisions
Part XX Amendment of the Constitution

Article 368 in Part XX gives the power of Parliament to amend the Constitution and sets out the procedure.

How are powers divided between the Union and the States?

Federalism in India is shaped by the Seventh Schedule rather than by a rigid separation. The Constitution gives the Union stronger powers in case of conflict, yet it protects the field of the State List for State Legislatures. For exam answers, describe India as a federal system with a strong Union bias and explain it through the repugnancy rule.

The Seventh Schedule has three lists: the Union List, the State List and the Concurrent List. Parliament makes laws on the Union List, State Legislatures on the State List, and both on the Concurrent List. Only Parliament can legislate on matters in neither the State nor the Concurrent List.

  1. Subject is listed in Seventh Schedule
  2. Union List: Parliament
  3. State List: State Legislature
  4. Concurrent List: both
  5. Conflict: Parliament's law prevails unless State law has Presidential assent

If a State law conflicts with a law of Parliament on a Concurrent subject, the Parliament's law prevails to the extent of repugnancy. A State law that has received the assent of the President prevails in that State.

What is the role of the Supreme Court?

The Constitution is the supreme law, so someone must interpret it and guard it. That task falls to the courts, with the Supreme Court as the final authority. Because the Court can invalidate laws that violate the Constitution, it shapes how the basic provisions evolve over time.

The Constitution provides a single integrated system of courts to administer both Union and State laws. The Supreme Court is at the apex, followed by the High Courts and the district courts. Its decisions bind all courts in the territory of India.

  • The Court consists of the Chief Justice of India and not more than 37 other judges appointed by the President.
  • Judges retire at the age of 65.
  • A Judge can be removed only by the President after an address by each House of Parliament, backed by a majority of total membership and two thirds of those present and voting.
  • The independence of the judiciary is part of the basic structure of the Constitution.

The basic structure idea limits the power of amendment. For the cases that shaped it, refer to the Basic Structure Judgment page on the Supreme Court website.

What is the Uttar Pradesh angle?

Uttar Pradesh is a State under Part VI of the Constitution and its Legislature makes laws on the State List within the framework above. The Constitution also contains Part IX on Panchayats and Part IXA on Municipalities, which govern the local bodies of the State as they do in all States. The sources used here do not name a specific Uttar Pradesh Act, so for State laws refer to the Uttar Pradesh government and legislature portals.
