Indian Constitution & Political Structure

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

The Constitution of India was adopted on 26 November 1949 and came into force on 26 January 1950. It is the longest written constitution in the world, containing 395 articles (originally) and now well over 450 articles after amendments, divided into 25 parts and 12 schedules. Dr B.R. Ambedkar chaired the Drafting Committee and is widely regarded as the principal architect of the Constitution.

The Indian Parliament consists of three tiers: the President of India at the top, followed by two houses — the Lok Sabha (House of the People) and the Rajya Sabha (Council of States). The President is the head of state and is elected by an electoral college comprising members of both Houses of Parliament and state legislative assemblies. The Prime Minister is the head of government and leads the executive branch.

The Supreme Court of India is the highest court of appeal, consisting of one Chief Justice and up to 34 other judges. It has original jurisdiction in disputes between states, writ jurisdiction for fundamental rights, and appellate jurisdiction for constitutional matters. The Constitution guarantees six fundamental rights under Part III: right to equality (Articles 14–18), right to freedom (Articles 19–22), right against exploitation (Articles 23–24), right to freedom of religion (Articles 25–28), cultural and educational rights (Articles 29–30), and right to constitutional remedies (Article 32).

⚡ Exam tip: SNAP questions on Indian Constitution often test dates (26 November Constitution Day, 26 January Republic Day), the number of articles or parts, and the name of the principal architect. Questions on the fundamental rights section and the structure of Parliament are also frequently asked. Remember that the President is elected, not directly voted upon by citizens.

Parliamentary System: Lok Sabha and Rajya Sabha

Lok Sabha, the lower house, has a maximum of 552 members — 530 from states, 20 from union territories, and 2 nominated by the President from the Anglo-Indian community. Members are elected directly by adult universal suffrage for a five-year term. Money bills can only be introduced in Lok Sabha, and Rajya Sabha can only recommend amendments to money bills; it cannot reject them. The Rajya Sabha has 245 members maximum: 233 elected by state legislative assemblies and 12 nominated by the President for their contributions to art, literature, science, and social service. Rajya Sabha is a permanent body — one-third of its members retire every two years.

The President of India

The President is elected using a single transferable vote system by an electoral college consisting of all elected members of Parliament and state legislative assemblies. The President serves a five-year term and can serve any number of terms. Key powers include promulgating ordinances (Article 123), granting pardons (Article 72), and sending messages to Parliament. The President exercises these powers on the advice of the Council of Ministers headed by the Prime Minister.

Governor and State Legislature

Each state has a Governor appointed by the President. States with bicameral legislatures (Andhra Pradesh, Bihar, Karnataka, Maharashtra, Telangana, Uttar Pradesh) have a Legislative Council (upper house), while others have a unicameral Vidhan Sabha. The Governor has discretionary powers in certain cases, such as recommending President’s Rule under Article 356.

Emergency Provisions (Articles 352–360)

India has three types of emergencies: National Emergency (Article 352) declared during war or external aggression; President’s Rule (Article 356) imposed when state governments cannot function; and Financial Emergency (Article 360) which can declare a financial crisis. The first National Emergency was declared in 1971 during the Bangladesh war.

Common traps in SNAP GK questions: Students confuse the original number of articles (395) with the current count after amendments (over 450). Another frequent error is mixing up the legislative powers of Lok Sabha and Rajya Sabha — remember that Rajya Sabha cannot reject money bills. Also note that the Chairman of Rajya Sabha is the Vice-President of India, not the President.

Historical Context and the Constituent Assembly

The Constitution of India was drafted by the Constituent Assembly, which was constituted in December 1946 under the Cabinet Mission Plan. The Assembly had 299 members and met for the first time on 9 December 1946, with Sachchidananda Sinha as its first President. Dr Rajendra Prasad became the permanent President of the Assembly. The Constitution was adopted on 26 November 1949 — this date is now celebrated as Constitution Day (Samvidhan Divas). The majority of its provisions came into force on 26 January 1950, which is celebrated as Republic Day.

Key Sources of the Indian Constitution

The drafters drew from multiple constitutional models: the Government of India Act 1935 (administrative structure), the US Constitution (fundamental rights, independent judiciary, president), the British Constitution (parliamentary system, cabinet responsibility), the Irish Constitution (directive principles of state policy), the Canadian Constitution (center-state relations), and the Japanese Constitution (constitutional review by courts).

Amendment Process (Article 368)

The Constitution can be amended by Parliament. Most amendments require a simple majority of those present and voting, plus two-thirds of members present and voting in each House. Certain amendments (affecting federal structure, judiciary, representation) require half the states to ratify before the President certifies them. The 42nd Amendment (1976) was the most extensive, adding 46 new clauses during the Emergency. As of 2024, there have been 106 constitutional amendments.

Directive Principles of State Policy (Part IV, Articles 36–51)

These are non-justiciable guidelines for the government in framing laws and policies. They include provisions inspired by the Irish Constitution and the UN Declaration of Human Rights. Notable DPSPs include Article 45 (free and compulsory education for children), Article 48 (organisation of agriculture and animal husbandry), and Article 51A (fundamental duties added by 42nd Amendment).

Fundamental Duties (Article 51A)

Added by the 42nd Amendment in 1976, these ten duties include abiding by the Constitution, cherishing national heritage, maintaining unity, and protecting the environment. They were based on recommendations of the Swaran Singh Committee.

Federal Structure and Centre-State Relations

India’s constitution establishes a quasi-federal structure — more unitary than a pure federation but more federal than a unitary state. The Seventh Schedule (Articles 245–246) divides powers into three lists: Union List (defence, foreign affairs, currency — 100 subjects), State List (police, agriculture, health — 61 subjects), and Concurrent List (education, forests, marriage — 52 subjects). Residuary powers vest with Parliament.

SNAP-specific question patterns: SNAP tends to focus on factual recall — specific articles, sections, schedules, and landmark cases. Questions on the preamble, fundamental rights, and constitutional bodies (Election Commission, UPSC, Finance Commission) appear regularly. Watch for questions pairing the 42nd Amendment with the Emergency period, or linking specific articles to landmark Supreme Court judgments.
