What best describes the Australian Constitution?

The Australian Constitution is best described as a legal document outlining the rules for governance. It establishes the framework for the political and legal structure of Australia, detailing the roles and powers of the various branches of government, including the Parliament, the Executive, and the Judiciary. This foundational text serves to outline the distribution of power between the Commonwealth and the states, sets forth the processes for making laws, and defines the rights of Australian citizens.

The Constitution is not primarily a guide for economic policies; rather, it includes provisions that impact economic governance, but its main purpose is to provide a legal foundation for the functioning of government. While it can be considered a historical document, it is more than just a record of past laws; it is an active legal instrument that governs contemporary political processes. Lastly, it is not a declaration of independence, as Australia did not enact a constitution to sever ties with the British Empire but rather to establish a systemic governance structure under a federation model. Thus, describing it as a legal document outlining rules for governance captures its essence and primary function effectively.
