31 The Constitution
The Australian Constitution is the set of legal principles by which Australia is governed. It describes how the Parliament is composed, how Parliament works, lists the powers of the Parliament, defines how federal and state Parliaments share power, refers to the role of the High Court and many other things.
Before 1901, Australia consisted of six separate colonies ruled by the British parliament and government. Many Australian colonists wanted their colonies to unite into one federation. During the 1890s, a series of public meetings, called conventions, were organised throughout the six colonies to decide the shape of a new federal Constitution. Some of the people who ran these meetings wrote a Constitution which was voted on by citizens in each colony.
After the colonial citizens had voted in favour of the new Constitution, it was passed as a British Act of Parliament in 1900 and came into force on 1 January 1901.
The Constitution is divided into 128 Sections. Although many sections appear to be simple, they have lead to different interpretations and legal arguments over the last century. Section 51 has turned out to be particularly significant because it lists the areas in which the Commonwealth Parliament can make laws. These areas include taxes, defence, trade and commerce with other countries, marriage and divorce, immigration, postal services, invalid and old-age pensions, among other things. Another important Section is 109, which states that if the Commonwealth and a state Parliament both pass laws on the same subject, the Commonwealth law over-rules the state law.
Surprisingly, the Constitution does not mention the Prime Minister or the Cabinet, both of which are central to the working of government and the Parliament. For these and other reasons, some people say that the Constitution is out of date and that constitutional reform is needed.
The Constitution may only be changed by a referendum. In a referendum, each eligible Australian over the age of 18 votes on a specified change to the Constitution. A referendum is only passed if it is approved by a majority of voters in a majority of states, and by a majority of voters across the nation as a whole. Since 1901, of 44 proposed changes to the Constitution only eight have been passed.
All Acts of Parliament must conform to the requirements of the Constitution. If citizens believe that an Act of Parliament is unconstitutional, they can take the Australian government to the High Court of Australia, which is responsible for making legal judgments about any matter relating to the Constitution.
