In a bicameral legislature, the opposition plays a critical role in maintaining a system of checks and balances. The opposition comprises parties or members not in power, providing alternative perspectives and scrutinizing the actions of the ruling party. This debate fosters accountability and ensures that diverse viewpoints are represented in policy discussions. Through questioning, proposing amendments, or blocking legislation, the opposition can influence legislative outcomes and safeguard against potential abuses of power. Overall, the presence of an effective opposition is vital for sustaining a healthy democratic process.
