Which principle allows accountability of the legislative branch in governance?

The principle that allows accountability of the legislative branch in governance is judicial review, which ensures that legislative actions can be challenged. This mechanism is fundamental to the checks and balances built into the governance structure, allowing the judiciary to assess the constitutionality of laws passed by the legislature. If a law is found to violate the constitution, judicial review enables the courts to nullify it, thereby holding the legislature accountable for its actions and ensuring that legislative authority is exercised within the bounds of constitutional principles.

This principle reinforces the notion that no branch of government operates in isolation; rather, they must operate within a system that encourages oversight and responsibility, promoting transparency and fairness in governance.
