A bicameral legislature refers to a particular body of government that consists of two legislative houses or chambers – the Senate and the House of Representatives. When the two bodies work together, a bicameral system ensures more voices are heard, reduces corrupt influence over Congress, eliminates the ability of power to fall into the hands of a few and deliberately slows the legislative process to ensure fairness and reduce rash legislation.
The importance of bicameral legislature is such that bills which are produced are done in such a manner as to best represent the will of the people and the will of the states. The bicameral nature of congress attempts to ensure that both groups, states and individual citizens, are adequately represented.
Bicameral legislature is necessary to maintain an effective system of checks and balances, which will prevent from legislation being enacted into law that would unfavourably affect a certain faction or government or its people. The two chambers would serve as checks against each other's authority, theoretically preventing either from ever gaining tyrannical power. With checks and balances, each of the three branches of government can limit the powers of the others. This way, no one branch becomes too powerful. Each branch “checks” the power of the other branches to make sure that the power is balanced between them
A two-house legislature better balances the competing values of responsiveness to the people and stability in the law, more restrained in its actions, and therefore more likely to preserve a desirable steadiness and reliability in the law. Because a bicameral legislature has more legislators, committees, and leaders, it possesses inherently more capacity and expertise, and therefore greater authority and independence in relations with the governor and other agencies of government.
