Important Articles of the Indian Constitution: DPSP, Parliament and PM Powers

Study Notes · General Studies · Indian Polity

UPSC guide to Directive Principles (Articles 36-51), Parliament (79-122) and Prime Minister powers (74-75). Key articles, amendments and Prelims-ready list.

Introduction

Article numbers are the most tested factual layer of the Indian Constitution in the UPSC Prelims. A candidate who can place the right number against the right provision turns a difficult paper into a comfortable one. Yet isolated memorisation does not survive Mains questions, which ask why a principle exists, how it has been interpreted, and what its contemporary relevance is.

This article takes three clusters that together dominate question papers: Directive Principles of State Policy (Articles 36 to 51), the articles related to Parliament (79 to 122), and the articles related to the Prime Minister (74, 75, 78 and allied). For each cluster, we set out the provisions, the interpretation through landmark cases and amendments, and the exam angle. The article is designed as a consolidated reference for Polity revision and as a basis for structured Mains answers.

Background and Historical Context

India’s Constitution, adopted on 26 November 1949 and commenced on 26 January 1950, drew its design from multiple sources. The Directive Principles were consciously modelled on the Irish Constitution of 1937, which in turn drew on the Spanish Republican Constitution of 1931. The framers led by B. R. Ambedkar, Alladi Krishnaswami Ayyar and K. M. Munshi debated whether social and economic rights should be justiciable. The compromise was Part IV, non-justiciable but “fundamental in the governance of the country”.

Articles governing Parliament and the executive were shaped by the Government of India Act 1935, adapted to a parliamentary rather than viceregal model. The Cabinet Mission Plan 1946, Constituent Assembly debates from December 1946 to November 1949, and the Objectives Resolution of December 1946 moved by Jawaharlal Nehru provided the political frame.

Three lines of constitutional interpretation are indispensable for understanding how article numbers translate into working law today. First is the evolution from the Minerva Mills (1980) clarification that Fundamental Rights and Directive Principles together form the basic structure. Second is the Keshavananda Bharati (1973) basic structure doctrine itself, flowing from Article 368. Third is the doctrine of harmonious construction, which has been used consistently to read Parts III and IV as complementary.

Amendments reshape article content. The 42nd Amendment 1976 added Articles 39A, 43A and 48A, inserted Part IV-A with Article 51A, and expanded the preamble. The 44th Amendment 1978 restored judicial review. The 73rd and 74th Amendments 1992 added Articles 243 to 243ZG for Panchayats and Municipalities, a natural extension of Article 40.

Key Provisions of the Three Clusters

Directive Principles of State Policy (Articles 36 to 51)

Part IV classifies the Directive Principles along three ideological streams: socialist, Gandhian and liberal-intellectual. The core numbers are:

Articles Related to Parliament (79 to 122)

Part V Chapter II sets out the composition, powers and procedure of the Union legislature:

Articles Related to the Prime Minister (74, 75, 78)

Important Articles of the Indian Constitution: DPSP, Parliament and PM Powers

Significance for UPSC and General Knowledge

Detailed Analysis: DPSP in Action

The Directive Principles have been operationalised through law, policy and judicial interpretation. Article 39(b) and (c), on equitable distribution of material resources, provided the constitutional ground for the nationalisation cases of the 1960s and 1970s, including the bank nationalisation and privy purse decisions. Article 39A led to the Legal Services Authorities Act 1987 and the Lok Adalat system. Article 40 was given teeth by the 73rd Amendment Act 1992, inserting Part IX with Articles 243 to 243O.

Article 41 and 45, read together with Article 21 as interpreted in Unnikrishnan (1993) and the 86th Amendment (2002) inserting Article 21A, translated the promise of education into a justiciable right, followed by the Right of Children to Free and Compulsory Education Act 2009. Article 42 supports maternity benefit law and the labour codes of 2020. Article 43 inspires minimum wage legislation and the new wage code. Article 43B anchors the 97th Amendment’s cooperative provisions.

Article 44 on a Uniform Civil Code remains the most debated directive, invoked in Shah Bano (1985), Sarla Mudgal (1995) and Shayara Bano (2017). Article 47 underlies prohibition policy in some states and the National Food Security Act 2013. Article 48A and Article 51A(g) have been used by the Supreme Court to build environmental jurisprudence, notably in M. C. Mehta and Vellore Citizens Welfare Forum. Article 50 guided the Criminal Procedure Code 1973 reforms separating police from judiciary in districts.

The Minerva Mills case definitively held that Parts III and IV are complementary, overruling the earlier view in Champakam Dorairajan (1951) that Fundamental Rights override Directive Principles. This harmonious reading is the operative doctrine today.

Comparative Perspective

How do Directive Principles compare with their counterparts elsewhere?

FeatureIndia (DPSP)Ireland (1937)South Africa (1996)United Kingdom
LocationPart IV, Articles 36-51Article 45Socio-economic rights in Bill of RightsNo codified constitution

ScopeSocial, economic, internationalSocial and economicHousing, health, education, foodStatutory welfare
Source of inspirationIrish modelSpain 1931ICCPR, ICESCRCommon law
Constitutional weightFundamental in governanceGuiding for legislatureBinding on stateConvention

The Indian approach sits between the Irish and South African models. It is formally non-justiciable but has been used by courts to interpret Fundamental Rights expansively, particularly through Articles 14 and 21.

Challenges and Criticisms

Three lines of criticism recur. First, non-justiciability is argued to make DPSP a “pious wish”. Supporters respond that judicial interpretation of Articles 14 and 21 has operationalised many Directive Principles anyway, and that legislative compliance is widespread. Second, contradictions are alleged between directives, for example Article 43 on living wage and Article 47 on prohibition, or Article 44 on Uniform Civil Code and Article 29 on minority cultural rights. These are best read as political priorities to be balanced rather than legal contradictions. Third, the question of implementation gap is real. India’s social indicators on child nutrition, primary education outcomes, and sanitation lag the aspirations of Articles 45, 47 and 48A.

On Parliament-related articles, contemporary debates include the frequency of joint sittings (only four in the Republic’s history, under Article 108), the declining time spent on legislative scrutiny, and the constitutionality of money-bill routing under Article 110 flagged by the Supreme Court in Rojer Mathew (2019). On Prime Minister-related articles, the 91st Amendment’s 15-percent cap and the convention-heavy character of Articles 74, 75 and 78 raise accountability questions.

Prelims Pointers

Mains Practice Questions

  1. “Directive Principles are not legally enforceable but are constitutionally fundamental.” Examine the role of judicial interpretation in bridging this gap. (250 words)
  1. Critically analyse the articles governing the Prime Minister and the Council of Ministers, especially in the context of accountability. (250 words)

Conclusion

Polity for the UPSC is less about memorising 470-odd articles and more about understanding how three or four dense clusters produce the bulk of questions. The Directive Principles, the Parliament chapter and the articles governing the Prime Minister together account for a significant share of both Prelims factual questions and Mains analytical questions.

The aspirant’s real task is to combine three layers: article numbers, landmark amendments, and key case law. A table of article numbers without cases produces a dull Prelims answer; a case law summary without article numbers produces a shallow Mains answer. This article has tried to interleave the two so that the reader leaves with both the reference list and the interpretive frame needed for full marks.

Frequently Asked Questions

What are DPSP articles in the Indian Constitution?

Directive Principles of State Policy are contained in Part IV of the Indian Constitution, Articles 36 to 51. They set out guidelines for the state in making laws and policies towards a welfare society. Though not justiciable under Article 37, they are declared fundamental in the governance of the country and are a key source of legislation on social and economic rights.

Why are DPSP articles important for UPSC?

Article numbers within Part IV are frequent Prelims factual questions, while Mains GS2 answers on welfare, socio-economic rights, federal governance and judicial activism rely on DPSP. Amendments like the 42nd, 44th, 86th, 91st and 97th that added or modified DPSP and related articles link the Constitution to current policy, making them high-yield for both papers.

How are DPSP articles related to Parliament and PM articles?

DPSP (Part IV) set the substantive goals of governance. Parliament articles (79-122, Part V Chapter II) provide the legislative machinery to translate these goals into statutes, while Articles 74, 75 and 78 on the Prime Minister and Council of Ministers shape executive implementation. Together they form a complete governance loop from principles to procedure to policy delivery.

Which amendments added new DPSP articles?

The 42nd Amendment 1976 added Articles 39A (equal justice and free legal aid), 43A (workers’ participation in management) and 48A (environment, forests and wildlife). The 86th Amendment 2002 modified Article 45. The 97th Amendment 2011 added Article 43B on cooperative societies. Fundamental Duties under Article 51A were also added by the 42nd Amendment.

What is the difference between Fundamental Rights and DPSP?

Fundamental Rights (Part III, Articles 12 to 35) are justiciable and enforceable by writs in the Supreme Court under Article 32. DPSP (Part IV, Articles 36 to 51) are non-justiciable under Article 37 but constitutionally fundamental. The Minerva Mills judgment (1980) held that both parts form the basic structure and must be read harmoniously.

Which articles of the Constitution relate to Parliament?

Articles 79 to 122 in Part V Chapter II govern Parliament. Important numbers: 79 (composition), 80-81 (Rajya Sabha and Lok Sabha size), 83 (duration), 100 (quorum), 105 (privileges), 108 (joint sitting), 109-110 (Money Bills), 112 (Annual Financial Statement or Budget) and 122 (bar on courts from inquiring into Parliamentary proceedings).

Which articles govern the Prime Minister?

Articles 74, 75 and 78 are the core provisions. Article 74 mandates a Council of Ministers headed by the PM to aid and advise the President; since the 42nd and 44th Amendments this advice is binding subject to one reconsideration. Article 75 covers appointment, oath, responsibility to Lok Sabha and the 15 percent cap added by the 91st Amendment. Article 78 lists PM’s duties to inform the President.

What is Article 44 and why is UCC debated?

Article 44 is a Directive Principle requiring the state to endeavour to secure a Uniform Civil Code (UCC) for citizens throughout India. It is debated because personal laws on marriage, divorce, inheritance and adoption currently differ across religious communities. Supreme Court observations in Shah Bano (1985), Sarla Mudgal (1995) and Shayara Bano (2017) have urged implementation, while opponents cite minority rights under Articles 25 to 30.
