Final answer:
The Australian Constitution acts as a check on the Parliament by interpreting the Constitution, protecting rights, requiring double majority in a referendum, having a bicameral structure, and ensuring separation of powers.
Step-by-step explanation:
The Australian Constitution acts as a check on the Parliament in law-making through various means:
- The High Court interprets the Australian Constitution to ensure that laws made by Parliament are consistent with it.
- The Constitution includes an express protection of rights that limits the power of Parliament to infringe upon individual liberties.
- A double majority (a majority of voters overall and a majority in a majority of states) is required in a referendum to change the Constitution, which serves as a check on Parliament's ability to amend the Constitution at will.
- The Australian Parliament has a bicameral structure with two houses (the Senate and the House of Representatives), which allows for independent consideration and review of legislation before it becomes law.
- The Constitution also establishes a system of separation of powers, dividing the powers of governance among the Parliament, the Executive, and the Judiciary, preventing any one branch from becoming too powerful.
