Which legal principle ensures that legislative bodies can function effectively and independently?

The principle of parliamentary privilege is essential for ensuring that legislative bodies can function effectively and independently. This principle grants members of the legislature certain rights and protections that are vital for the enactment of laws without outside interference.

Parliamentary privilege includes the right to speak freely in debates and discussions without the risk of facing legal repercussions for statements made in the course of their duties. This freedom is crucial for fostering an environment where legislators can openly express their views, challenge one another, and pursue their parliamentary responsibilities without fear of external pressure or retribution.

Additionally, parliamentary privilege protects the legislature from interference by the judiciary or the executive branch, thereby preserving the separation of powers and allowing legislative bodies to work autonomously. This ensures that legislators can fulfill their roles effectively, hold the government to account, and represent the interests of their constituents without undue influence.

Judicial independence, legislative supremacy, and federalism, while important principles within the constitutional framework, do not specifically address the operational independence and effectiveness of legislative bodies in the manner that parliamentary privilege does.
