The Constitution of India AIBE (G)

AIBE 2026 – Constitution of India

Welcome, future advocates. The Constitution of India is the supreme lex loci. For the All India Bar Examination (AIBE), it is crucial not just to read it like an ordinary statute, but to understand its Parts, Articles, Schedules, Writs, and Doctrines holistically. Use this module for quick, conceptual revision.

1. Introduction & The Preamble

Introduction to the Constitution

  • Adoption & Commencement: Adopted on 26 Nov 1949; Commenced on 26 Jan 1950.
  • Supreme Law: It is the *grundnorm* (basic norm) from which all other laws derive authority.
  • AIBE Importance: High weightage. Questions test conceptual clarity on Articles, recent case laws, and foundational doctrines.

The Preamble

The Preamble is the identity card of the Constitution, outlining its objectives.

Key Words:
  • Sovereign: India is internally supreme and externally free.
  • Socialist: Democratic socialism (added by 42nd Amendment, 1976).
  • Secular: State has no official religion (added by 42nd Amendment, 1976).
  • Democratic: Government by the people.
  • Republic: Head of state (President) is elected, not a monarch.

Exam Trap: The Preamble *is* a part of the Constitution and *can* be amended, but its basic structure cannot be altered (Kesavananda Bharati case).

2. Salient Features & Union Territory

Salient Features

  • Lengthiest Written Constitution: Comprehensive document containing Parts, Articles, and Schedules.
  • Federal with Unitary Bias: Normal times = Federal (division of power); Emergency = Unitary (Centre becomes all-powerful).
  • Parliamentary Form: Executive is responsible to the Legislature.
  • Synthesis of Parliamentary Sovereignty & Judicial Supremacy: Parliament can amend, but Supreme Court can strike down laws violating the Basic Structure.

Union and Its Territory (Part I: Articles 1-4)

  • Article 1: India, that is Bharat, shall be a Union of States.
  • Article 2: Admission or establishment of new states.
  • Article 3: Formation of new states, alteration of boundaries/names (Requires prior recommendation of the President).
Example: Creating Telangana from Andhra Pradesh was done under Article 3 via an ordinary legislative process, not a constitutional amendment under Article 368.

3. Citizenship (Part II: Articles 5-11)

Deals with citizenship *at the commencement* of the Constitution (Jan 26, 1950).

  • Article 5: Citizenship by domicile.
  • Article 9: Single citizenship (Voluntarily acquiring foreign citizenship terminates Indian citizenship).
  • Article 11: Gives Parliament absolute power to regulate the right of citizenship by law (Resulted in Citizenship Act, 1955).

Exam Trap: Fundamental Rights under Articles 15, 16, 19, 29, and 30 are available *only* to citizens, not foreigners.

4. Fundamental Rights (Part III: Articles 12-35)

Referred to as the Magna Carta of India. They act as limitations on the tyranny of the Executive and arbitrary laws of the Legislature.

Right to Equality (14-18)

  • Art 15: Prohibition of discrimination on grounds *only* of religion, race, caste, sex, or place of birth.
  • Art 16: Equality of opportunity in public employment.
  • Art 17: Abolition of Untouchability.

  • Art 19: Six freedoms (Speech, Assembly, Association, Movement, Residence, Profession). Subject to reasonable restrictions (Art 19(2) to 19(6)).
  • Art 21: Protection of life and personal liberty. (Expanded to include right to privacy, clean environment, speedy trial).
  • Art 21A: Right to Education (6-14 years).

Right against Exploitation (23-24)

  • Art 23 & 24: Prohibits human trafficking, forced labor, and child labor in hazardous factories.

Right to Freedom of Religion (25-28)

  • Art 25: Freedom of conscience and free profession, practice, and propagation of religion (subject to public order, morality, health).

Cultural and Educational Rights (29-30)

  • Art 30: Right of minorities (religious or linguistic) to establish and administer educational institutions.

Right to Constitutional Remedies (32)

Article 32: Dr. B.R. Ambedkar called it the "Heart and Soul of the Constitution." It gives the right to move the Supreme Court directly for the enforcement of Fundamental Rights via Writs.

5. DPSP & Fundamental Duties

Directive Principles of State Policy (Part IV: Articles 36-51)

Instructions to the State for securing social and economic justice. They are non-justiciable (cannot be enforced in a court), but fundamental in the governance of the country.

  • Art 39A: Equal justice and free legal aid.
  • Art 44: Uniform Civil Code.
  • Art 50: Separation of judiciary from executive.

Fundamental Duties (Part IVA: Article 51A)

Added by the 42nd Amendment (1976) on Swaran Singh Committee's recommendation. Originally 10, now 11 (11th added by 86th Amendment).

AIBE Takeaway: FDs are non-justiciable moral obligations on citizens. Example: To abide by the Constitution and respect its ideals.

6. Executive & Parliament

The President & Executive (Part V)

  • Art 52 & 53: There shall be a President of India in whom executive power is vested.
  • Art 74: President acts on the "aid and advice" of the Council of Ministers headed by the PM.

  • Appellate Jurisdiction: Appeals from High Courts.

8. Emergency & Centre-State Relations

Centre-State Relations (Part XI & XII)

Legislative relations (Art 245-255). Power is divided via the 7th Schedule (Union List, State List, Concurrent List). Residuary powers belong to the Centre (Art 248).

9. Amendment & Schedules
