The Legislative Process: How a Bill Becomes an Act - TCE Legal Studies (Tasmania)

Syllabus dot point

“Describe the legislative process by which a bill passes through parliament and becomes an Act.”

8 min read

Quick answer

A proposed law starts as a bill. It passes through several readings and debate in the first house, then repeats the process in the second house, and finally receives royal assent from the Crown's representative. Only then does it become an Act and part of the statute law.

What this dot point is asking

This dot point asks you to describe, step by step, how a bill travels through parliament to become enforceable law.

Where a bill comes from

A bill is a proposed law that has not yet been passed. Most bills are government bills, prepared by the executive to carry out its policy, and introduced by the responsible minister. A bill introduced by a member who is not a minister is called a private member's bill. Before drafting, the government may release a green paper (discussion document) or white paper (firm proposals) and consult the public, interest groups and experts.

Bill

A draft or proposed law placed before parliament for debate. It does not have legal force until it has passed both houses and received royal assent, at which point it becomes an Act.

Passage through the first house

A bill usually begins in the lower house (in Tasmania, the House of Assembly; federally, the House of Representatives), though some bills can start in the upper house. The main stages are:

  • First reading: the bill is introduced and its title is read; there is no debate.
  • Second reading: the minister explains the purpose and the house debates the general principles. This is the main policy debate, and the house votes on whether to proceed.
  • Committee or consideration in detail stage: the bill is examined clause by clause and amendments can be made.
  • Third reading: the house votes on the final form of the bill.

If the bill passes the third reading, it moves to the second house.

Passage through the second house

The second house (the Legislative Council in Tasmania, or the Senate federally) repeats essentially the same stages. As a house of review, it may pass the bill, amend it, or reject it. If it makes amendments, the bill returns to the first house, which must agree to the changes. The two houses may pass a bill back and forth until they reach agreement. A bill must pass both houses in identical form.

A bill must clear both houses

Except for special deadlock procedures, a bill becomes law only if both houses pass it in the same terms. This is why the upper house can act as a genuine check: it can amend or block a bill the government wants.

Royal assent

Once both houses agree, the bill is sent to the Crown's representative for royal assent. In Tasmania this is the Governor; for Commonwealth bills it is the Governor-General. Royal assent is the formal signing that turns the bill into an Act of Parliament. By convention assent is granted on ministerial advice and is effectively a formality. After assent the Act commences either on a date stated in the Act or on a date later proclaimed.

Deadlocks

The two houses can disagree so completely that a bill cannot pass. The Commonwealth Constitution provides a mechanism in section 57 for resolving such deadlocks through a double dissolution, where both houses are dissolved and an election is held, followed if necessary by a joint sitting. This shows how the system balances the upper house's reviewing power against the government's need to govern.

Why this process matters

The multi-stage process is not just bureaucracy: it is the practical expression of representative and responsible government. Each reading gives elected members a chance to scrutinise and improve the proposal, the committee stage allows detailed and expert input, and the requirement that both houses agree forces compromise and prevents a government from rushing controversial law through unchecked. Delegated legislation made under an Act is a faster alternative for technical detail, but it must stay within the limits set by the parent Act, so the elected parliament keeps ultimate control. For Tasmania, the independence of many Legislative Council members means the upper house can genuinely reshape or stall a government bill, making the process a real check rather than a rubber stamp.

Answering "How does a bill become an Act?"

A common task asks you to walk through the process in order. Work through it in steps.

Step 1: Origin of the bill

State that a proposed law is a bill, usually a government bill introduced by the responsible minister, sometimes after a green or white paper.

Step 2: Passage through the first house

List the first reading (introduction), second reading (main policy debate and vote), committee stage (clause-by-clause amendment) and third reading (vote on the final form).

Step 3: Passage through the second house

Explain that the second house repeats the stages and may pass, amend or reject the bill, and that the bill must pass both houses in identical form.

Step 4: Royal assent and commencement

Explain that the Crown's representative grants royal assent, turning the bill into an Act, which then commences on a stated or proclaimed date.

Thinking a bill is law once the lower house passes it

Students often assume a bill becomes law as soon as the government's house approves it. In fact it must also pass the upper house and receive royal assent. Until then it is still only a bill with no legal effect.

For exam answers, list the stages in order (first reading, second reading, committee, third reading, then the same in the second house, then royal assent), and stress that a bill must pass both houses and receive assent before it becomes an Act.

Outline the stages a bill passes through in the first house of parliament.

A 6 mark response needs the stages in order with a brief note on what each does.

First reading. The bill is introduced and its title read; there is no debate.

Second reading. The minister explains the purpose and the house debates the general principles; this is the main policy debate and the house votes on whether to proceed.

Committee or consideration in detail stage. The bill is examined clause by clause and amendments can be made.

Third reading. The house votes on the final form of the bill, and if passed it moves to the second house.

Markers reward the correct order and identifying the second reading as the key policy debate.

Practice12 marks
Describe the full process by which a bill becomes an Act and analyse the role of the upper house in that process.
Show worked answer →

A 12 mark response needs the complete process and an analysis of the upper house as a check.

Origin and first house. Explain that a bill starts as a proposed law (usually a government bill) and passes the first reading, second reading, committee stage and third reading in the first house.

Second house. Explain that the second house repeats the stages and may pass, amend or reject the bill; if amended it returns to the first house, and the bill must pass both houses in identical form.

Royal assent. Explain that the Crown's representative (Governor in Tasmania, Governor-General federally) gives assent, turning the bill into an Act, conventionally on ministerial advice.

Analysis. Judge the upper house as a genuine check because it can amend or block bills, but note that its power varies: a government with an upper house majority faces little resistance, and deadlocks can be resolved (section 57 double dissolution federally). Markers reward a defended judgement on how real the check is.
