Prime Minister and Council of Ministers - Appointment, Powers, Collective Responsibility, Cabinet Committees, and Constitutional Position

Prime Minister and Council of Ministers for UPSC

Definition/Key Term

Prime Minister (PM) is the head of the Union Council of Ministers and the real executive in India's parliamentary system. Formally appointed by the President under Article 75, the PM leads the government, coordinates ministries, and is responsible to the Lok Sabha through the principle of collective responsibility.

Definition/Key Term

Council of Ministers (CoM) is the group of ministers headed by the Prime Minister that aids and advises the President (Article 74). It includes Cabinet Ministers, Ministers of State (with/without independent charge), and (in practice) may also include Deputy Ministers. The Constitution fixes key rules like collective responsibility (Article 75(3)) and the 15% size cap (Article 75(1A)).


1) Introduction: Constitutional Head vs Real Executive (Why PM Matters Most)

India follows a parliamentary form of government. This means the executive is split into:

In daily governance, the President generally acts on the advice of the Council of Ministers. Therefore, although many powers are formally written in the President's name, the real decision-making centre is the PM-led executive. The Supreme Court has repeatedly underlined this logic in cases explaining the "aid and advice" system and the limited personal discretion of the constitutional head.

2) Constitutional Provisions: Articles 74–75 (Core) and Related Articles (Exam Map)

The constitutional foundation of the Prime Minister and the Council of Ministers is mainly in Articles 74 and 75:

For UPSC, you should also connect Articles 74–75 with "supporting provisions" that explain how the PM actually functions:

Provision What it means for PM/CoM (UPSC-useful)
Article 74 CoM advises President; advice becomes binding (42nd Amendment); President can return once (44th Amendment).
Article 75 Appointment of PM; ministers appointed on PM advice; pleasure doctrine; collective responsibility; 15% cap via Article 75(1A).
Article 78 PM's duty to keep President informed and submit matters for President's consideration (key for PM–President relationship).
Article 77 Business of Government of India is conducted in President's name; rules of business allocate work among ministers (practical governance tool).
Article 88 Ministers can participate in Parliament proceedings (even if not a member of that House) but cannot vote unless they are members.
Article 75(5) A minister who is not a member of either House must become a member within 6 months (important Prelims fact).

Definition/Key Term

Aid and Advice means the President normally acts on the binding advice of the Council of Ministers headed by the PM. The President can ask for reconsideration once, but must accept the advice if reiterated.

3) Appointment of the Prime Minister: Text, Conventions, Hung Parliament, and Key Episodes

Textual rule: Article 75(1) says the Prime Minister is appointed by the President. But the Constitution does not lay down a step-by-step selection method (like "invite largest party first" etc.). Therefore, constitutional conventions fill the gap.

3.1 Normal Scenario: Clear Majority

If a single party wins a majority in the Lok Sabha, the convention is simple: the President appoints the leader of the majority party as Prime Minister.

3.2 The 6-Month Rule (Often Asked)

The PM (like any minister) may be from Lok Sabha or Rajya Sabha. If the person is not a member of either House at appointment, they must become a member within 6 months (Article 75(5)).

3.3 Hung Parliament Scenario: What Does the President Do?

In a hung parliament (no single party majority), the President must ensure the appointed PM can command majority support on the floor of the Lok Sabha. In practice, the President uses conventions and (if disputed) the most accepted democratic method: floor test in the Lok Sabha.

A common exam-friendly priority order (based on widely followed conventions) is:

  1. Pre-poll alliance with clear majority (choose its leader).
  2. Single largest party if it can show support to reach majority.
  3. Post-poll coalition with written support letters, choosing a leader.
  4. Post-poll "outside support" arrangement (minority government with external support), if it can prove majority in floor test.

Key point for UPSC: The President's appointment power is not a free choice; it is guided by the objective of ensuring a stable government responsible to Lok Sabha (Article 75(3)).

3.4 Key Appointment Episodes (Asked in Mains & Interviews)

These examples show how conventions work in real politics (especially in coalition eras):

Definition/Key Term

Hung Parliament means no single party has a majority in the Lok Sabha. The PM is appointed using conventions to ensure the person can prove majority support on the floor of the House.

4) Powers and Functions of the Prime Minister: Executive, Legislative, Financial, and Strategic Roles

In UPSC, PM's powers are best written under clear headings. Remember: many PM powers are not directly written as "PM shall do X", but come from the PM's position as leader of the Council of Ministers, leader of the majority, and the link between President–Cabinet–Parliament.

4.1 Executive Powers (Most Important)

4.2 Legislative Powers (PM inside Parliament)

4.3 Financial Powers (Budget and Priorities)

4.4 Strategic and National Roles

Definition/Key Term

"Primus inter pares" vs "PM-centric government": Ideally, PM is "first among equals" in the cabinet. In practice, strong leadership and institutional support (PMO, committees) can make the system more PM-dominant, especially during emergencies or major reforms.

5) Council of Ministers: Composition, Categories, and Constitutional Rules

The Council of Ministers is the team that runs the Union government. Article 74 establishes the CoM to aid and advise the President, and Article 75 lays down appointment and responsibility rules.

5.1 Composition and Size

5.2 Categories of Ministers (Exam-Favourite)

In practice, ministers are commonly grouped into ranks:

UPSC caution: The Constitution does not neatly classify ministers into these ranks; these categories are largely based on conventions and the Rules of Business. This is exactly why UPSC asked about it in Prelims 2022.

5.3 Membership Rule (6 Months)

A person can be appointed as a minister (including PM) even if not currently a member of either House, but must become a member within 6 months (Article 75(5)).

5.4 Oath and Secrecy

Ministers take oath of office and secrecy (Third Schedule). The secrecy aspect connects strongly with the convention of cabinet confidentiality.

6) Collective Responsibility (Article 75(3)): Meaning, Working, and Exam Applications

Article 75(3) says: the Council of Ministers is collectively responsible to the House of the People (Lok Sabha). This is the backbone of parliamentary government.

6.1 What Collective Responsibility Actually Means

6.2 Collective Responsibility vs Coalition Politics

In coalition governments, partners may disagree openly. Still, the constitutional principle remains: the government must retain Lok Sabha confidence. Therefore, coalition coordination mechanisms (common minimum programmes, coordination committees) become politically necessary to keep collective responsibility workable.

6.3 Important Case Law Link: Continuity Even After Dissolution

In U.N.R. Rao v Indira Gandhi (1971), the issue was whether the Council of Ministers ceases to exist after the Lok Sabha is dissolved. The Court held that the PM and ministers continue to hold office to ensure continuity of governance, even when the House is dissolved, until a new House is formed.

Definition/Key Term

Collective Responsibility is the constitutional rule that the Council of Ministers is jointly accountable to the Lok Sabha. If the House withdraws confidence, the whole ministry falls.

7) Individual Responsibility and "Pleasure of the President" (Article 75(2))

Article 75(2) says ministers hold office during the pleasure of the President. In a parliamentary system, this "pleasure" is exercised in line with political reality—meaning, in practice, the President acts on the advice of the Prime Minister.

7.1 What Individual Responsibility Means in Practice

7.2 Difference from Collective Responsibility

7.3 Legal Responsibility (Important Clarification)

In India, legal responsibility of ministers (being personally liable in court for official acts) is limited because actions are taken in the name of the President and executed through rules and procedures. Political responsibility (collective/individual) remains the core accountability mechanism.

8) Cabinet vs Council of Ministers: Conceptual Clarity + Detailed Comparison Table

UPSC repeatedly tests the difference between Cabinet and Council of Ministers. The key is: Cabinet is a smaller, powerful subset within the Council of Ministers.

Definition/Key Term

Cabinet is the core group of senior ministers (usually Cabinet Ministers) that takes major policy decisions. It is a subset of the Council of Ministers. Though not fully defined in the Constitution, it is central to the working of parliamentary government.

Basis Cabinet Council of Ministers (CoM)
Meaning Small inner group of senior ministers; top decision-making body All ministers headed by PM (Cabinet + MoS + others)
Size Small (limited number) Large (subject to 15% cap)
Status in Constitution Not clearly defined; concept exists in practice (and referenced in some contexts) Clearly constitutional via Articles 74 and 75
Role Decides major policies, bills, national priorities Assists in administration, implements policies, handles ministries
Meetings Meets frequently for key decisions As a full body, meets rarely; works mainly through departments
Decision-making More powerful and centralised Broader collective but many members are not part of core decisions

Exam-ready line: The Cabinet is the "steering committee" of the Council of Ministers.

9) Kitchen Cabinet and Inner Cabinet: Meaning, Usefulness, and Risks

Kitchen Cabinet refers to an informal group of trusted persons (often senior ministers, close advisers, sometimes non-minister aides) who influence key decisions. Inner Cabinet is similar but usually refers to a small circle within the Cabinet itself.

9.1 Why Do Kitchen Cabinets Emerge?

9.2 Democratic Concerns

Definition/Key Term

Kitchen Cabinet is an extra-constitutional, informal decision-influencing group around the PM. It can increase efficiency but may reduce transparency and cabinet-style collective decision-making.

10) PM's Relationship with the President: Advice, Information, and Limited Discretion

The PM–President relationship is the best place to show "constitutional head vs real executive" using precise articles.

10.1 Aid and Advice (Article 74)

Article 74 establishes that the President acts on the aid and advice of the Council of Ministers headed by the PM. After constitutional amendments, the President can ask for reconsideration once, but must accept the advice if reiterated.

10.2 PM as the Link (Article 78)

The PM has a constitutional duty to keep the President informed about government decisions and administrative matters and to submit matters for consideration when required. This makes the PM the key channel connecting formal executive authority with real political executive functioning.

10.3 What About "Discretion"?

In normal times, the President's personal discretion is very limited at the Union level. The meaningful grey zone generally appears during hung parliament situations (choosing whom to invite to form government), but even there the guiding objective is the same: identify a person most likely to command majority support and require a floor test quickly.

11) Prime Minister vs Chief Minister: Detailed Comparison Table (Highly Scorable)

UPSC loves PM vs CM comparisons because both are "real executives" in parliamentary systems but operate in different constitutional environments (Union vs State).

Basis Prime Minister (Union) Chief Minister (State)
Constitutional base Articles 74–75 (core), 78 (information duty) Articles 163–164 (State CoM and CM)
Appointed by President (Article 75(1)) Governor (Article 164)
Real executive Yes; heads Union CoM Yes; heads State CoM
House responsible to Lok Sabha (Article 75(3)) State Legislative Assembly (Article 164(2))
Policy domain Union List + shared influence in Concurrent List + national policy leadership State List + shared Concurrent List + state governance
Relationship with constitutional head President mostly bound by advice (Article 74) Governor has limited discretion; but discretion debates are more visible at state level
Cabinet committees Major Union cabinet committees chaired/controlled by PM States may have committees; usually less institutionalised than Centre

12) Cabinet Committees: CCS, ACC, CCEA and Why They Matter in Governance

Cabinet Committees are small groups of ministers formed to reduce Cabinet workload and speed up decisions. They are extra-constitutional (not detailed in the Constitution) but extremely powerful in real governance.

12.1 Why Cabinet Committees Exist

12.2 Major Cabinet Committees (Commonly Asked)

Committee Full Form Typical Role (UPSC-ready)
CCS Cabinet Committee on Security National security, defence and strategic decisions (highest security forum).
ACC Appointments Committee of the Cabinet Approves key senior appointments in the Government of India; major postings.
CCEA Cabinet Committee on Economic Affairs Major economic policy decisions, investment, infrastructure, pricing/allocations in key sectors.
CCPA Cabinet Committee on Parliamentary Affairs Parliamentary strategy, legislative agenda, coordination with floor managers.
Political Affairs Often called "Super Cabinet" informally Handles major political strategy issues (varies by government).

12.3 Chairmanship and Control

Most key cabinet committees are chaired by the Prime Minister (especially CCS, ACC, CCEA), which increases the PM's coordinating power over governance.

13) Cabinet Secretariat and PMO: Institutional Support Systems Behind PM-Led Governance

13.1 Cabinet Secretariat

Cabinet Secretariat provides secretarial and coordination support to the Cabinet and Cabinet Committees. It helps in agenda-setting, follow-up on decisions, inter-ministerial coordination, and policy coherence. It is headed by the Cabinet Secretary (top civil servant), who acts as a neutral coordinator across ministries.

13.2 Prime Minister's Office (PMO)

PMO is the staff office that supports the Prime Minister in policy coordination, monitoring, correspondence, appointments scheduling, and strategic inputs. It is not mentioned in the Constitution, but it has become a powerful coordination hub in modern governance. UPSC has directly asked about PMO's evolution in optional papers, showing its relevance.

13.3 Cabinet Secretariat vs PMO (UPSC-ready contrast)

Basis Cabinet Secretariat PMO
Primary function Supports Cabinet and committees; inter-ministerial coordination Direct support to PM; monitoring, coordination, strategic inputs
Nature Institutional civil service coordination body PM-centric staff agency
Accountability debate Seen as neutral coordinator Often criticised if it overshadows ministers/cabinet deliberation

15) UPSC PYQs (3) with Model Answers

UPSC PYQ (Prelims 2013)

Question (Polity): Consider the following statements: (1) The Council of Ministers at the Centre shall be collectively responsible to the Parliament. (2) The Union Ministers shall hold the office during the pleasure of the President of India. (3) The Prime Minister shall communicate to the President about the proposals for legislation. Which of the statements given above is/are correct?

Model Answer/Analysis: Statement (1) is incorrect because collective responsibility is specifically to the Lok Sabha (Article 75(3)), not to Parliament as a whole. Statement (2) is correct (Article 75(2)). Statement (3) is treated as correct based on the PM's constitutional duty to keep the President informed and communicate key government matters (Article 78-related duty). Hence, 2 and 3 only.

UPSC PYQ (Prelims 2022)

Question (Polity): Consider the following statements: (1) The Constitution of India classifies the ministers into four ranks viz. Cabinet Minister, Minister of State with Independent Charge, Minister of State and Deputy Minister. (2) The total number of ministers in the Union Government, including the Prime Minister, shall not exceed 15 percent of the total number of members in the Lok Sabha. Which of the statements given above is/are correct?

Model Answer/Analysis: Statement (1) is incorrect because these "ranks" are primarily conventions and not a constitutional classification. Statement (2) is correct due to Article 75(1A) (inserted by the 91st Amendment). Therefore, 2 only.

UPSC PYQ (Public Administration Paper II, 2011)

Question: Discuss the evolution of the role of the Prime Minister's Office (PMO) since independence.

Model Answer/Analysis (How to write in UPSC style): Start by stating PMO is extra-constitutional but emerged for coordination and support to the PM. Trace evolution from a secretarial assistance model to a policy coordination and monitoring hub as governance became complex (coalitions, economic reforms, security challenges, multi-ministry missions). Explain drivers of PMO's growing role: need for faster coordination, monitoring implementation, crisis management, and political leadership style. Then critically analyse concerns: cabinet deliberation may reduce, ministers' autonomy may shrink, and transparency issues may arise if decisions bypass formal processes. Conclude with balanced reforms: strengthen cabinet committees, clarify workflows, improve parliamentary oversight of executive actions, and ensure PMO supports (not replaces) cabinet government.

Prelims Angle

PYQs show traps: Lok Sabha vs Parliament; constitution vs conventions; 15% cap and article linkage.

Mains Angle

Use PMO question to write balanced governance answers: efficiency + accountability, with institutional reforms.

Answer Key

1-(c), 2-(b), 3-(b), 4-(c), 5-(c), 6-(b)


17) Conclusion: Exam-Ready Wrap-up

The Prime Minister and Council of Ministers form the real executive core of India's parliamentary system. Articles 74–75 create the constitutional framework: CoM aids and advises the President, ministers hold office during the President's pleasure, and the ministry is collectively responsible to the Lok Sabha.

For Prelims, success depends on precision: correct articles, clauses, limits (15%), and common traps (Lok Sabha vs Parliament; constitution vs conventions). For Mains, scoring answers combine structure + balance: PM's coordinating leadership and cabinet efficiency on one side, and concerns of centralisation (PMO/kitchen cabinet) and accountability on the other. If you present both dimensions with constitutional grounding and practical examples, this topic becomes a high-return area in Polity and Governance.
