Difficulty: Very hardThe Legislature: Unicameralism and Bicameralism

In a federal constitutional arrangement, proponents of retaining a bicameral structure often resist proposals to adopt unicameralism on economic grounds. Which of the following constitutional imperatives is most directly compromised if a federal state abolishes its upper legislative chamber in favor of a single-chamber legislature?

  1. The equal or specialized representation of federating units to prevent dominant regions from overriding minority state interestsAnswer
  2. B
    The operational power of the judiciary to conduct judicial review over enactments passed by parliament
  3. C
    The retention of political sovereignty exclusively within the elected representatives of the lower house
  4. D
    The constitutional requirement that local government councils exercise delegated legislative power over concurrent list items

Answer

The equal or specialized representation of federating units to prevent dominant regions from overriding minority state interests
In a federal government, bicameralism is structurally designed to solve the problem of representation balance. The lower chamber represents citizens by population size, while the upper chamber represents the federating units (states or regions) on an equal or special basis. Transitioning to a unicameral system risks leaving smaller constituent units vulnerable to population-dominated lawmaking.

Step-by-Step Solution

1
Analyze the structural functions of bicameralism in a federal state
Identify that federal systems utilize a second chamber (e.g., Senate) to guarantee equal or special representation for constituent units regardless of population size.
Federalism requires institutional mechanisms to balance popular representation with state/regional equality.
2
Evaluate the impact of transitioning to unicameralism
Recognize that a single chamber usually bases representation predominantly on population, allowing heavily populated regions to dominate policy decisions.
Abolishing the upper chamber eliminates the structural counterweight designed to safeguard minority constituent states.
3
Distinguish correct institutional principle from wrong options
Confirm that inter-organ checks like judicial review, concepts of political sovereignty, and local government powers operate independently of national legislative chamber count.
Option choices testing judicial review, sovereignty, and local delegation misattribute inter-organ checks or system-wide power arrangements to internal legislative chamber design.
