Unicameral and Bicameral legislature are the classification of legislature depending on the number of units or chambers that make up the legislature. The organisation of the legislature is a key feature of every constitution. It could be a unicameral (one chamber) or bicameral (two chambers) body. Small countries with unitary governments are likely to have unicameral legislatures. Bicameral legislatures are common in federal states, whether large or small, with one house representing the main territorial subdivisions. This article explains the Unicameral and Bicameral legislature which is important for UPSC Indian Polity Preparation.

What is Legislature?

• The legislature is a part of the government that has the authority to enact laws and regulate how they are carried out.
• The two most common types of legislatures worldwide are:
  • Unicameral
  • Bicameral.
• A unicameral legislature is a form of government in which only one central body has the authority to enact laws and make policy decisions.
• On the other hand, a bicameral legislature has two houses of parliament, the Lower house representing the people of the country and the Upper house representing the States.
• The two houses of this sort of legislature have the same powers.
• The major function of the legislature is to enact laws. It is the basis upon which the other two institutions, the executive and the judiciary, are built.
• It is also typically accorded top priority among the three organs since there can be no law implementation or application unless and until laws are established.

Historical Background

• The Government of India Act of 1919, which formed the Rajya Sabha in 1921, began India's shift from unicameral to bicameral legislature.
• The Simon Commission in 1927 was split on its practicality, citing complexity and cost as reasons.
• Then, in 1935, the Government of India Act established bicameral legislatures in each of India's provinces.

What is a Unicameral Legislature?

• When there is only one house in a parliamentary system to perform all of the legislature's activities, such as enacting laws, passing a budget, overseeing administration, debating developmental plans, international relations, national plans, and so on, this is referred to as a Unicameral legislature or Unicameralism.
• It is a type of legislature in which the state/law of a country is made and implemented by only one chamber (one central entity).
• The following are some countries with unicameral national legislatures:
  • Iran
  • Norway
  • Sweden
  • Hungary
• Indian states are the best examples of unicameral state legislatures. There are 24 Indian states (Including 2 UTs, Delhi and Puducherry) with a unicameral structure out of 28 states and 8 UTs.

What is a Bicameral Legislature?

• The bicameral legislature, or bicameralism, refers to a country's legislative body, which consists of two different chambers, the Upper House and the Lower House, which share powers.
• Its major goal is to guarantee that all sectors or segments of society are fairly represented in Parliament.
• It is a two-house legislative body. India is one such example, with two houses at the national level as well as in six of the country's 28 states.
• The function of administering and enforcing legislation is shared between the two houses in a bicameral legislature.
• The Indian Parliament is divided into two houses at the national level:
  • Lok Sabha is a legislative body of India (Lower House)
  • Rajya Sabha is a legislative body of India (Upper House)
• Six of the 28 state legislatures are divided into two chambers:
  • Legislative Assembly (Vidhan Sabha)
  • Legislative Council (Vidhan Parishad)
• The six states with bicameral legislatures are as follows:
  • Andhra Pradesh
  • Bihar
  • Karnataka
  • Maharashtra
  • Telangana
  • Uttar Pradesh

Constitutional Provisions

Article 79

• Article 79 of the Constitution specifies the structure of parliament.
• The President and the two houses, the Lower House or House of People and the Upper House or Council of States, are included in the Parliament.

Conclusion

The unicameral legislature is common in nations where the bicameral legislature is not required, and the key advantage is that lawmaking is simple. Many nations throughout the world have established a bicameral legislature in order to provide all socioeconomic groups and sectors a voice. Despite the fact that some states have established a bicameral legislature, the Legislative Council's legislative powers pale in comparison to its equivalent at the centre, the RajyaSabha. There must be productive debates in order to envision more powers for the legislative council and for it to serve its genuine purpose rather than just as a back door for defeated candidates.

GS Mains Questions and Model Answers

Q1: Compare and contrast the unicameral and bicameral systems of legislature with examples.

Answer: Unicameral and bicameral legislatures differ in structure, representation, and legislative processes. A unicameral legislature consists of one house, making the law-making process simpler, faster, and cost-effective. Countries like Norway and New Zealand have unicameral systems. In contrast, a bicameral legislature has two houses, often with different functions and powers, providing checks and balances, greater representation, and detailed legislative scrutiny. Examples include the Indian Parliament, which has the Rajya Sabha (Upper House) representing states and the Lok Sabha (Lower House) representing the people. While unicameral systems offer efficiency, bicameral systems ensure wider representation and more comprehensive review of legislation.

Q2: Discuss the advantages and challenges of a bicameral legislature in a parliamentary democracy like India.

Answer: A bicameral legislature in India offers several advantages, including checks and balances, broader representation of regional and state interests through the Rajya Sabha, and more comprehensive scrutiny of bills. It prevents hasty decisions and ensures that laws are thoroughly debated before enactment. However, challenges include potential delays in legislation due to differing opinions between the two houses, increased costs of maintaining two chambers, and occasional deadlocks over critical issues. Balancing efficiency with thorough scrutiny is key to maximizing the effectiveness of a bicameral legislature in a parliamentary democracy.

Q3: Explain how the Rajya Sabha and Lok Sabha function together to ensure legislative balance in India’s bicameral system.

Answer: The Rajya Sabha (Upper House) and Lok Sabha (Lower House) work together in India's bicameral parliamentary system to ensure legislative balance. The Lok Sabha, directly elected by the people, represents popular will and initiates most bills, including money bills. The Rajya Sabha, representing states and union territories, reviews and suggests amendments to bills passed by the Lok Sabha, ensuring regional interests are considered. Both houses must approve a bill for it to become law, except in the case of money bills, where the Rajya Sabha's role is limited. This collaboration ensures a thorough legislative process, balanced representation, and comprehensive review of proposed laws.

Previous Year Questions on  Unicameral and Bicameral legislature

1. UPSC CSE 2020

Question: Evaluate the effectiveness of the bicameral system in maintaining checks and balances within the Indian Parliament.

Answer: The bicameral system in the Indian Parliament, comprising the Rajya Sabha and the Lok Sabha, effectively maintains checks and balances by providing two levels of legislative scrutiny. The Lok Sabha represents the people and initiates most legislation, while the Rajya Sabha represents states and ensures regional concerns are addressed. This dual structure prevents the concentration of power, promotes detailed discussion of bills, and allows for amendments and review. However, disagreements between the two houses can delay legislation. Despite occasional challenges, the system promotes balanced governance and prevents hasty decision-making, reflecting India's federal structure and democratic values.

2. UPSC CSE 2019

Question: Discuss the relevance of unicameral and bicameral legislatures in the context of federal and unitary states.

Answer: Unicameral and bicameral legislatures have distinct roles in federal and unitary states. Unicameral legislatures, with a single legislative body, are common in unitary states where centralized governance and simpler legislative processes are preferred. They offer efficiency, lower costs, and faster law-making. In federal states, bicameral legislatures are more common to ensure balanced representation of regions or states. The bicameral system, such as in India and the United States, allows for greater scrutiny of legislation and representation of diverse regional interests, maintaining a balance of power between the central and state governments. Each system is relevant based on the country's governance structure and need for representation.
