Parliament and State Legislatures

India’s parliamentary and state legislative system is the engine that translates constitutional principles into everyday governance, and it is a high‑frequency topic in the UPSC Civil Services Examination. Mastery of how the Union Parliament and the State Legislatures are constituted, how they function, and how they interact with each other equips candidates to answer questions on federalism, law‑making, budgetary control, and the anti‑defection regime with confidence.

What it covers

The module begins with the basic architecture – “Parliament: Structure and Composition” explains the bicameral set‑up, while “Lok Sabha: Composition, Election and Powers” drills down into the lower house’s electoral mechanics and authority. “Parliament: Functioning and Legislative Procedure” then follows the life‑cycle of a bill, from introduction to passage, highlighting the role of privileges and voting.

Next, the temporal dimension of parliamentary work is explored through the “Budget Session” and “Monsoon Session”, showing how the Constitution mandates regular sittings and how the Union Budget is presented under Article 112.

The inter‑institutional checks are examined via “Parliamentary Committees” and “Constitutional and procedural basis for constituting ad‑hoc committees”, which together illustrate the detailed scrutiny that supplements floor debates.

The module then shifts to the state level. “State Legislatures” outlines the composition and powers of Vidhan Sabhas and Vidhan Parishads, while “Relations Between State Legislature and Centre” and “Power of Parliament to legislate on matters in the State List on the recommendation of the President (Article 249)” map the constitutional provisions that allow the centre to legislate on state subjects in the national interest.

Finally, the anti‑defection framework is covered through “Tenth Schedule: Grounds for Disqualification” and “Judicial Review of Anti‑Defection Decisions”, linking the constitutional text to judicial oversight. Together, these strands reveal how legislative authority, fiscal control, federal balance, and party discipline are woven into a single constitutional fabric.

Where to start

1. Parliament: Structure and Composition – establishes the two‑chamber system that underpins every subsequent topic.
2. Lok Sabha: Composition, Election and Powers – builds on the structure by detailing the most powerful house and its electoral basis.
3. Parliament: Functioning and Legislative Procedure – shows how laws are actually made, a prerequisite for understanding sessions and committees.
4. Budget Session – demonstrates the constitutional requirement for annual financial legislation and introduces Article 112.
5. Tenth Schedule: Grounds for Disqualification – introduces the anti‑defection provisions that recur in many UPSC questions and connects to the later article on judicial review.

Reading these articles in the suggested order provides a logical scaffold: from the institutional skeleton, through the procedural bloodstream, to the specialised mechanisms that keep the system accountable and cohesive.
