Parliamentary System in India (UPSC Polity)

Study Notes · General Studies · GS II · Indian Polity

UPSC guide to the parliamentary system: merits, demerits, reasons for adoption, presidential system debate, and the basic-structure verdict.

The parliamentary system is the foundation on which Indian democracy is built. Adopted from the British Westminster model, it fuses the legislative and executive branches — the government is drawn from and accountable to Parliament. For UPSC Polity, the parliamentary system is essential reading for GS-II questions on separation of powers, executive accountability, and the ongoing presidential vs parliamentary debate.

What Is a Parliamentary System?

A key feature of any political system is the relationship between the assembly and the government — between the legislative and executive authorities. In a parliamentary system:

Reasons for Adopting the Parliamentary System

Familiarity

K.M. Munshi noted during the Constituent Assembly Debates that responsible government had already been introduced in British India. The conventions of the parliamentary system were already understood.

Avoiding Legislative-Executive Conflict

B.R. Ambedkar argued that a newly independent developing country must be able to deliver on its government's agenda. What would happen if the budget got stalled in an adversarial presidential system? Parliamentary fusion solves this coordination problem.

Diversity and Representation

In a diverse country like India, a parliamentary system results in an executive that closely resembles the population. The Cabinet collectively represents the social fabric of the country in a way a single elected president cannot.

Basic Structure Status

In Kihoto Hollohan (1992) and subsequent cases, the Supreme Court treated the parliamentary form of government as part of the basic structure of the Constitution. This means Parliament cannot switch to a presidential system through ordinary amendment.

The Presidential System Debate: Arguments "Against"

The Debate in Historical Context

The presidential-system debate resurfaces whenever:

Feasibility and Desirability

Feasibility

Unless the Supreme Court changes its mind on basic structure, a formal switch to a presidential system is constitutionally foreclosed.

Desirability

There are many presidential models — US, France (semi-presidential), South Africa. Key parameters include:

The US presidential office is highly powerful — India must ask whether it is ready to concentrate that much power in a single person.

The Viable Path: Reform Within

Rather than switching systems, the more pragmatic path is reforming the parliamentary system:
