The legislative process (SACE Stage 2 Legal Studies)
“Explain how parliament makes statute law, including the stages a bill passes through to become an Act.”
Parliament makes statute law by passing a bill through a set sequence of stages in both houses. A bill is introduced and read, debated and voted on in the lower house, then sent to the upper house where the process repeats, and finally given royal assent by the Crown's representative. Only after assent does the bill become an Act of Parliament and enforceable law.

What this dot point is asking
You must explain the role of parliament as a law-maker and describe, in order, the stages a bill passes through. Use correct terminology for both the Commonwealth and South Australia.
Parliament as the supreme law-maker
Statute law, also called legislation, is the main source of new law in Australia. Parliament is the supreme law-maker within its constitutional powers: it can make, change or repeal law, and statute prevails over inconsistent common law. Most Australian parliaments are bicameral, meaning they have two houses, plus the Crown.
- The Commonwealth Parliament has the House of Representatives (lower house) and the Senate (upper house), with the Governor-General representing the King.
- The South Australian Parliament has the House of Assembly (lower house) and the Legislative Council (upper house), with the Governor representing the King.
A bill must usually pass both houses and receive royal assent. The two-house structure provides a check, often called a house of review, so legislation is scrutinised twice before it can become law.
The stages of a bill
A bill is a proposed law. To become an Act it passes through these stages, usually starting in the lower house.
- First reading. The bill is formally introduced and its title read. There is no debate.
- Second reading. The minister explains the purpose and principles of the bill, and members debate its general merits. This is the main debate stage.
- Committee or consideration in detail stage. Members examine the bill clause by clause and propose amendments.
- Third reading. The bill, as amended, is voted on in its final form in that house.
- The other house. The bill is sent to the upper house, where the same stages are repeated. The upper house may pass it, amend it or reject it.
- Royal assent. Once both houses agree on the same text, the Crown's representative (the Governor-General federally, or the Governor in South Australia) gives royal assent.
Royal assent is the formal approval of a bill by the Crown's representative. It is the final step that turns a bill into an Act of Parliament. In modern practice assent is a formality, but without it the bill does not become law.
From Act to enforceable law
After assent the bill becomes an Act. The Act usually states when it commences, which may be on a fixed date, on a date set by proclamation, or 28 days after assent if no date is specified. Only once it commences is the law in force and enforceable.
Do not say a bill becomes law as soon as the lower house passes it. It must pass both houses (where they exist) and receive royal assent. Skipping the upper house or assent is a common error in describing the process.
Why the process has so many stages
The multiple stages and the two houses serve clear purposes.
- They allow scrutiny and debate, so flaws can be identified and amendments made.
- The upper house acts as a house of review, providing a second, often independently composed check.
- They give time for public and expert input and for the opposition to test the government's reasoning.
The trade-off is that the process can be slow, and a government without a majority in the upper house may struggle to pass its program. Where the two houses deadlock at Commonwealth level, the Constitution provides a double dissolution mechanism to resolve the impasse.
When describing how a law is made, list the stages in order and name the house each occurs in. For full marks, add the purpose of the two-house system (scrutiny and review) rather than only reciting the stages. Examiners reward understanding of why the process exists.
South Australian and Commonwealth context
The process is essentially the same across Australian parliaments, with differences mainly in the names of the houses. In South Australia a bill passes the House of Assembly and the Legislative Council and receives assent from the Governor. Remembering the correct chamber names for the jurisdiction in the question shows precision and avoids losing easy marks.
A SACE extended response rewards a structured, evaluative argument grounded in the stages and their purpose.
Step 1: State a contention
Argue that the process produces well-scrutinised, democratic law but can be slow and politically shaped.
Step 2: Set out the process
List the stages of a bill through both houses, committee scrutiny and royal assent.
Step 3: Show the strengths
Explain how debate, scrutiny and the review function of the second house improve quality and legitimacy.
Step 4: Show the weaknesses
Explain how delay and government or hostile control of the houses can distort outcomes.
Step 5: Reach a judgement
Conclude that the process generally produces good law through scrutiny, despite limits of speed and political control.

An extended-response question wants a sustained, evaluative argument with a judgement, not a list of stages.
Contention. Argue that the process produces well-scrutinised, democratic law but can be slow and shaped by political control.
The process. The stages of a bill through both houses, committee scrutiny and royal assent, with the two-house system providing review.
Strengths. Debate, scrutiny and the review function of the second house improve the quality and legitimacy of law.
Weaknesses. The process can be slow, and government control of the lower house, or hostile numbers in the upper house, can distort outcomes.
Judgement. Conclude that the process generally produces good law through scrutiny and debate, while acknowledging the limits of speed and political control.
Markers reward the stages, the purpose of bicameral review and a reasoned evaluation.
2018 SACE Stage 2-style1 markIdentify one feature of the first reading stage in the law-making process.Show worked answer →
At the first reading stage, the Bill is formally introduced to the House and its long title is read; copies are made available to members. There is no debate and no vote on the substance at this stage - it simply puts the Bill before the House and places it on the record so that the second reading (where the principles are debated) can follow.
2018 SACE Stage 2-style1 markDefine what is meant by 'royal assent'.Show worked answer →
Royal assent is the formal approval of a Bill by the Crown's representative - the Governor-General for Commonwealth Bills, or the Governor for state Bills - after the Bill has passed both Houses of Parliament. It is the final stage in the law-making process, at which point the Bill becomes an Act of Parliament and law (commencing on a stated date or on proclamation).
2018 SACE Stage 2-style4 marksOutline the differences between public (government) Bills and private members' (or senators') Bills.Show worked answer →
For four marks, contrast the two on at least two clear points and develop them.
Public (government) Bills are introduced by a government minister and reflect government policy. Because the government usually commands a majority in the lower house, these Bills make up the great majority of legislation and are very likely to pass.
Private members' (or senators') Bills are introduced by a member or senator who is not a minister (including opposition, minor party and backbench members). They often raise issues of conscience or matters the government has not taken up. They are far less likely to pass, because they lack guaranteed government support and limited parliamentary time is given to them.
The key differences are who introduces the Bill, whether it carries government backing, and its likelihood of becoming law.
