- explain what a bill is and name the types of bills;
- describe the stages through which a bill becomes law.

What is the legislature?
The legislature is the organ of government responsible for making laws.
- Purpose: its laws give backing to government policies.
- Role: it guides the relationship between the government and the governed.
- Membership: it is made up of elected legislators, such as members of the House of Representatives, the Senate and the House of Assembly.
- Names: it may be called parliament or national assembly, and in some countries congress, as in the USA.
- Structure: it can have one chamber (unicameral) or two chambers (bicameral).
What are the functions of the legislature?
The legislature has eight main functions.
- Law making: its primary function is to make laws for the good governance of the country.
- Approval of executive policy: important policies such as treaties and declaration of war need legislative approval.
- Control of public funds: the legislature scrutinises and endorses government spending and taxation.
- Power of impeachment: it can remove the head of the executive if he commits a very serious offence. Impeachment means formally charging and removing an official from office.
- Monitoring of government activities: it checks government agencies and parastatals.
- Inquiry: it can order an inquiry into any public organisation and summon any official for questioning.
- Constitutional amendment: any change to the constitution requires legislative action.
- Education: it informs the public through debate on issues before it.
- Judicial functions: in some countries the legislature acts as a court in certain cases. Before 2009, the British House of Lords was the highest court in Britain.
What are the types of legislature?
There are two types of legislature: bicameral and unicameral.
What is a bicameral legislature?
A bicameral legislature is a legislature with two chambers: an upper house and a lower house.
- Nigeria: the National Assembly has the Senate (upper house) and the House of Representatives (lower house).
- Membership: in Nigeria and the USA, members of both houses are elected.
- Other examples: Australia, Mexico, Belgium, Brazil, India, Germany, Canada, Malaysia and Pakistan.
What are the advantages of a bicameral legislature?
- Thorough law making: a bill must pass through two houses, so it is discussed exhaustively.
- Checks and balances: if one house acts arbitrarily, the second house can call it to order.
- Experienced personnel: it makes room for politically and administratively experienced people in law making.
- Guard against despotism: the second chamber checks the tyranny of a one-chamber legislature.
- Equal representation of units: in a federation where the upper house gives equal seats to each unit, members feel equal.
- More democratic: most modern states adopt it for this reason.
- Check on the executive: it can restrain the executive, especially when the constitution is violated.
- Proper scrutiny: bills are properly debated, so better laws are made.
What are the disadvantages of a bicameral legislature?
- Expensive to run: a lot of funds are needed to maintain two chambers.
- Delay in passing bills: law making is slower than in a unicameral legislature.
- Rivalry: the two houses may quarrel over which is superior.
- Unsuitable in emergencies: delay is harmful when quick action is needed.
- Dumping ground: if the second chamber is by nomination or appointment, it may house political rejects who lost at the polls.
- Possibly undemocratic: in some countries, such as Britain, the upper house is not elected.
- Waste of resources: duplicated functions waste human and financial resources.
What is a unicameral legislature?
A unicameral legislature is a legislature with only one house that makes laws.
- Nigeria: it operates at state level. Each of the 36 states has one House of Assembly.
- Other examples: Ghana, Sierra Leone, Gambia, Cape Verde, Burkina Faso and Bulgaria.
What are the advantages of a unicameral legislature?
- Quick passage of bills: only one house considers a bill, so time is saved.
- Economical: money for the salaries and allowances of a second chamber is saved.
- Less room for filibusters: a filibuster is the use of long speeches to delay or block a vote, and one house gives less room for it.
- Ideal for small countries: it suits small countries with a homogeneous (similar) social and economic organisation.
- No dumping ground: it does not provide a place for political deadwood.
What is the difference between bicameral and unicameral legislatures?
| Point | Bicameral | Unicameral |
|---|---|---|
| Number of houses | Two | One |
| Passage of bills | Slow, as both houses must pass the bill | Quick, as one house passes the bill |
| Cost | Expensive | Cheaper |
| Checks on each other | One house checks the other | No second house to check it |
| Nigerian example | National Assembly | State House of Assembly |
What is parliamentary supremacy?
Parliamentary supremacy is the idea that parliament is the highest law-making authority in a state.
What are the limitations to parliamentary supremacy?
Seven things limit the supremacy of parliament.
- Constitutional limitation: the role of parliament is defined in the constitution.
- Judicial review: the courts, such as the Supreme Court, can declare acts of the legislature unconstitutional, null and void.
- International laws and rules: a country must obey rules of organisations it belongs to, such as the U.N.O., A.U., ECOWAS and OPEC.
- Interest groups: political parties and pressure groups, at home and abroad, can restrict parliament.
- Resources of the state: a country that depends on others militarily, economically or technologically has less freedom to act.
- Public opinion and mass media: their influence can limit what parliament does.
- Complexity of government: modern government needs power to be delegated to subordinate bodies, which limits parliament.
What is a bill?
A bill is a proposed law presented to parliament for discussion.
- Assent: a bill passed by parliament becomes law only when the president or head of state signs it.
What are the types of bills?
There are three types of bills: public bills, money bills and private member’s bills.
- Public bill: deals with matters that affect the whole country or a section of it. It comes from the executive arm.
- Money bill: deals with how the government raises and spends money. A budget of estimated revenue and expenditure is an example.
- Private member’s bill: introduced into parliament by a member of that house.
How does a bill become law?
A bill becomes law after it passes through readings, committee work and a vote in each house, then receives assent.
- First reading: a minister or member presents the draft of the bill to the clerk of the house.
- Second reading: the mover explains the purpose of the bill, and members debate for or against it. A vote is taken. If the majority votes for it, the bill moves on. If not, the bill ends.
- Committee stage: if the House accepts the principles of the bill, a committee discusses it in detail, amends it and reports.
- Report stage: the committee findings are reported to the House, or the amended bill is placed before it.
- Third reading: the House takes a final look to correct drafting errors and takes a final vote.
- The other house: the bill goes to the other house, where it passes through similar stages. If that house suggests amendments, both houses set up a joint committee to settle the differences.
- Assent: after passing all five stages in both the House of Representatives and the Senate, the bill goes to the president. It becomes law once he signs it.
