Which term refers to the principal authority of a state to govern without interference?

The term that refers to the principal authority of a state to govern without interference is parliamentary sovereignty. This concept emphasizes that the legislative body has the supreme legal authority within a state and is not subject to limitations by external bodies. Parliamentary sovereignty means that the parliament can create or abolish any law, and its decisions cannot be struck down by other institutions, ensuring that the state can govern itself without external interference.

In a parliamentary sovereignty system, laws made by the parliament cannot be challenged in court, except on procedural grounds. This underpins the rule of law and the relationship between the legislature and the state, ensuring that the governing body holds ultimate power in its jurisdiction.

Understanding this term is crucial in grasping how a state maintains its independence and authority over internal matters, differentiating it from other concepts such as federalism, which deals with the division of powers between different levels of government, constitutionalism, which focuses on limiting government through a constitution, and delegated power, which refers to powers assigned to subordinate entities rather than the principal governing authority.
