Introduction
The study of Union & State government structure forms the architectural backbone of Indian Polity. This subtopic examines how the Indian Constitution distributes power, defines institutional relationships, and establishes the operational framework for both the central and state governments. For BPSC aspirants, this is not merely a theoretical exercise—it is the most frequently tested area within the Polity syllabus, with 28 questions appearing across the available examination years (2018–2025). The depth and variety of these questions reveal that BPSC examiners demand more than rote memorisation; they test conceptual clarity, institutional understanding, and the ability to distinguish between closely related constitutional provisions.
The questions span a remarkable range: from the age qualification for Lok Sabha membership (BPSC 2018) to the intricacies of cut motions in Parliament (BPSC 2024), from the Governor's powers over state legislation (BPSC 2024) to the composition of the Presidential Electoral College (BPSC 2021). This diversity reflects the syllabus's breadth, but a closer analysis reveals recurring themes—appointments, disqualifications, parliamentary procedures, and the delicate balance between Union and State authorities. The difficulty level is moderate to high, with many questions requiring aspirants to navigate constitutional articles, judicial interpretations, and practical conventions simultaneously.
What makes this subtopic particularly challenging is the interplay between written constitutional provisions and unwritten conventions. For instance, while the Constitution states that the President is part of Parliament (Article 79), a BPSC 2018 question tested the nuanced understanding that the President is not a member of Parliament in the ordinary sense—a distinction that trips up many aspirants. Similarly, the Governor's role as both the constitutional head of the state and the President's agent creates conceptual tensions that BPSC frequently exploits.
This chapter will equip you with everything needed to master this subtopic. We will build from first principles, defining every term before using it, then move through the institutional architecture of the Union and State governments, examining their composition, powers, and interrelationships. We will analyse the 28 PYQs in detail, identify patterns in BPSC's testing approach, and forecast what might appear in future examinations. By the end, you will not only recall facts but understand the constitutional logic that underpins them—the difference between knowing that something is true and understanding why it is true.
Core Concepts & Foundations
Before diving into the specific institutions and their powers, we must establish a common vocabulary. Indian Polity, like any legal discipline, operates with precise terminology. Misunderstanding even one term can cascade into errors across multiple questions.
Union of India: The federal entity comprising all states and union territories, governed by the Constitution of India. The term "Union" was deliberately chosen over "Federation" by the Constituent Assembly to emphasise that India is indestructible—states cannot secede. This is a union of states, not a compact among them.
State Government: The constitutional machinery governing each state, consisting of the Governor (executive head), the Council of Ministers (real executive), and the State Legislature (law-making body). Article 153 to 213 of the Constitution detail the state executive, while Articles 168 to 212 cover state legislatures.
Parliament: The supreme legislative body of the Union, comprising the President, the Lok Sabha (House of the People), and the Rajya Sabha (Council of States). Article 79 establishes this tripartite structure. Parliament exercises legislative authority over subjects in the Union List and Concurrent List.
Legislature: The law-making organ of government. At the Union level, it is Parliament; at the state level, it is the State Legislature (either unicameral—Legislative Assembly—or bicameral—Legislative Assembly and Legislative Council). The term "legislature" is broader than "Parliament" as it includes state-level bodies.
Executive: The branch of government responsible for implementing laws and administering the state. At the Union level, the executive comprises the President, Vice-President, and Council of Ministers headed by the Prime Minister. At the state level, it comprises the Governor and Council of Ministers headed by the Chief Minister. Article 53 vests Union executive power in the President; Article 154 vests state executive power in the Governor.
Constitutional Head: The titular or ceremonial head of the executive who exercises powers on the aid and advice of the Council of Ministers. The President (Union) and Governor (State) are constitutional heads. They are bound by the advice of their respective Councils of Ministers except in certain discretionary matters.
Real Executive: The Council of Ministers headed by the Prime Minister (Union) or Chief Minister (State) that actually exercises executive power. The Constitution uses the phrase "aid and advice" to describe their relationship with the constitutional head, but the 42nd Amendment (1976) and subsequent Supreme Court judgments have made this advice binding.
Bicameralism: The practice of having two houses in a legislature. At the Union level, Parliament is bicameral (Lok Sabha and Rajya Sabha). At the state level, only six states have bicameral legislatures: Andhra Pradesh, Telangana, Uttar Pradesh, Bihar, Maharashtra, and Karnataka. Article 168 allows states to have either one or two houses.
Delimitation: The process of redrawing the boundaries of parliamentary and assembly constituencies to ensure equal representation based on population. The Delimitation Commission, established under the Delimitation Act, performs this task. The 2002 Delimitation was frozen until 2026 (tested in BPSC 2022) to encourage population stabilisation measures.
Electoral College: The body that elects the President of India. It consists of elected members of both Houses of Parliament and elected members of the Legislative Assemblies of all states and union territories. The total strength is 788 (tested in BPSC 2021), calculated as 543 Lok Sabha + 233 Rajya Sabha + 4,120 state assembly members (weighted by population).
Cut Motion: A parliamentary device used to oppose or reduce a demand for grant in the budget. There are three types: Policy Cut (disapproval of policy), Economy Cut (reduction in amount), and Token Cut (symbolic reduction). The objective is to reduce expenditure in the budget proposals (tested in BPSC 2024).
Censure Motion: A motion moved in Parliament or State Legislature to censure a specific minister or the entire Council of Ministers for a particular policy failure. Unlike a No-Confidence Motion, it must specify the reasons for censure and does not require the government to resign if passed (tested in BPSC 2025).
No-Confidence Motion: A motion moved in the Lok Sabha (or State Legislative Assembly) expressing lack of confidence in the Council of Ministers. If passed, the government must resign. It does not require reasons to be stated and can be moved only in the Lok Sabha, not the Rajya Sabha.
Official Language of the State: The language declared by the state legislature as the official language for transaction of business. Article 345 allows states to adopt any language in use in the state as its official language. Business in the state legislature must be transacted in the official language of the state, or Hindi, or English (tested in BPSC 2025).
Privilege of Legislature: Special rights and immunities enjoyed by legislatures and their members to ensure independent functioning. These include freedom of speech in the House, immunity from court proceedings for anything said in the House, and the right to regulate internal proceedings. Article 105 covers Parliament's privileges; Article 194 covers state legislatures' privileges.
Finance Commission: A constitutional body constituted every five years under Article 280 to recommend the distribution of tax revenues between the Union and states. The President determines the qualifications for appointment as a member of the Finance Commission (tested in BPSC 2025).
Backward Classes Commission: A commission established under Article 340 to investigate the conditions of socially and educationally backward classes and recommend measures for their improvement. The first such commission was chaired by Kaka Saheb Kalelkar (tested in BPSC 2018).
Order of Precedence: The hierarchical ranking of officials in India for ceremonial purposes. The President, Vice-President, Prime Minister, and Governors occupy the top positions. The Chairman of UPSC, Chief Election Commissioner, and Comptroller and Auditor General all hold the same rank (tested in BPSC 2019), creating confusion about who comes first.
Special Category Status (SCS): A classification granted by the National Development Council to certain states with geographical and socio-economic disadvantages, entitling them to preferential central assistance and tax concessions. Bihar was never granted SCS (tested in BPSC 2019), while states like Jammu and Kashmir, Himachal Pradesh, and Sikkim received it.
Land Revenue Officer: An official responsible for maintaining land records, collecting land revenue, and performing related administrative functions. The Patwari is the village-level land record officer (tested in BPSC 2019), distinct from the Lambardar (revenue collector), Zamindar (landlord), and Zaildar (intermediary in Punjab).
With these foundational terms established, we can now examine the institutional architecture in detail.
