Difference Between Unicameral and Bicameral Legislature

Main Difference – Unicameral vs Bicameral Legislature 

Unicameral and Bicameral Legislatures are two types of governments. The main difference between unicameral and bicameral legislature is that unicameral legislature consists of one house of parliament whereas bicameral legislature consists of two chambers or houses of parliament.

What is Unicameral Legislature

Unicameral legislature or unicameralism is the practice of having only one parliamentary or legislative chamber. At present, about half of the world’s sovereign states are unicameral. China, Vatican, Sri Lanka, Hungary, Iran, New Zealand, Norway, Sweden, Turkey, etc. are examples of countries that have a unicameral legislature. The main advantage of having a unicameral legislature is that it is the most effective of the legislatures because the legislative procedure is simpler since there are no gridlocks or deadlocks. Since a single chamber government can be run by fewer representatives, and with fewer resources, it saves a lot of money.

However, there are disadvantages of unicameralism as well. The main purpose of multicamera legislatures is the fair representation of the different sectors of the society. This purpose is not fulfilled in unicameralism.

What is Bicameral Legislature

Bicameral legislature or bicameralism is a system where there are two separate assemblies, houses or chambers. Countries like United States, United Kingdom, France, Canada, Italy, Spain, Japan, etc. have bicameral legislatures.

The manner in which the members are selected to each house is different from country to country. In the United States, the two houses are called the Senate and the Congress. In the United Kingdom, the upper house is called the House of Lords, and the lower house is called the House of Commons.

The main intention of creating bicameral legislature is to give distinct voices to separate sectors of the society. This system represents all social groups fairly. However, since there are two chambers, the lawmaking may not be efficient as in the case of unicameral legislature. Bicameral legislature may take a long time to pass a law since it needs to be approved by both the councils. In addition, a lot of resources, money have to be used to maintain this kind of legislature.
