He had little personal enthusiasm for the project, as he felt it was a waste of money and expenditure on it could not be justified at the time. Nevertheless, he designed the building by default. The construction of Old Parliament House, as it is called today, commenced on 28 August 1923 and was completed in early 1927. It was built by the Commonwealth Department of Works, using workers and materials from all over Australia. The final cost was about £600,000, which was more than three times the original estimate. It was designed to house the parliament for a maximum of 50 years until a permanent facility could be built, but was actually used for more than 60 years.

Composition and electoral systems

The Constitution establishes the Commonwealth Parliament, consisting of three components: the King of Australia, the Senate and the House of Representatives.


Monarch

All of the constitutional functions of the King are exercisable by the
governor-general Governor-general (plural governors-general), or governor general (plural governors general), is the title of an official, most prominently associated with the British Empire. In the context of the governors-general and former British colonies, ...

The government does not formally advise the governor-general to grant assent, but it is expected that they will act in accordance with the democratically elected houses of Parliament and assent has never been refused.


Senate

The upper house of the Australian Parliament is the
Senate A senate is a deliberative assembly, often the upper house or chamber of a bicameral legislature. The name comes from the ancient Roman Senate (Latin: ''Senatus''), so-called as an assembly of the senior (Latin: ''senex'' meaning "the el ...

, on which it was partly modelled, the Australian Senate includes an equal number of senators from each state, regardless of population. The Constitution allows Parliament to determine the number of senators by legislation, provided that the six original states are equally represented. Furthermore, the Constitution provides that each original state is entitled to at least six senators. However, neither of these provisions applies to any newly admitted states, or to territories. Since an act was passed in 1973, senators have been elected to represent the territories. Currently, the two

. Only half of the state Senate seats go up for re-election each three years (except in the case of a double dissolution) as they serve six-year terms; however territory Senators do not have staggered terms and hence face re-election every three years. Until 1949, each state elected the constitutional minimum of six senators. This number increased to ten from the 1949 election, and was increased again to twelve from the 1984 election.

in 1922, and to the Australian Capital Territory in 1948; these territorial representatives, however, had only limited voting rights until 1968. Federal electorates have their boundaries redrawn or redistributed whenever a state or territory has its number of seats adjusted, if electorates are not generally matched by population size or if seven years have passed since the most recent redistribution. From 1901 to 1949, the House consisted of either 74 or 75 members (the Senate had 36). Between 1949 and 1984, it had between 121 and 127 members (the Senate had 60 until 1975, when it increased to 64). In 1977, the High Court ordered that the size of the House be reduced from 127 to 124 members to comply with the nexus provision.

Both houses

It is not possible to be simultaneously a member of both the Senate and the House of Representatives, but a number of people have been members of both houses at different times in their parliamentary career. Only Australian citizens are eligible for election to either house. They must not also be a subject or citizen of a "foreign power". When the Constitution was drafted, all Australians (and other inhabitants of the British empire) were

Procedure

Each of the two Houses elects a presiding officer. The presiding officer of the Senate is called the

. Elections for these positions are by secret ballot. Both offices are conventionally filled by members of the governing party, but the presiding officers are expected to oversee debate and enforce the rules in an impartial manner. The Constitution authorises Parliament to set the

for each chamber. The quorum of the Senate is one-quarter of the total membership (nineteen); that of the House of Representatives is one-fifth of the total membership (thirty-one). In theory, if a quorum is not present, then a House may not continue to meet. In practice, members usually agree not to notice that a quorum is not present, so that debates on routine bills can continue while other members attend to other business outside the chamber. Sometimes the Opposition will " call a quorum" as a tactic to annoy the Government or delay proceedings, particularly when the Opposition feels it has been unfairly treated in the House. Proceedings are interrupted until a quorum is present. It is the responsibility of the

: the presiding officer puts the question, and, after listening to shouts of "Aye" and "No" from the members, announces the result. The announcement of the presiding officer settles the question, unless at least two members demand a " division", or a recorded vote. In that case the bells are rung throughout Parliament House summoning Senators or Members to the chamber. During a division, members who favour the motion move to the right side of the chamber (the side to the Speaker's or President's right), and those opposed move to the left. They are then counted by "tellers" (government and opposition whips), and the motion is passed or defeated accordingly. In the Senate, in order not to deprive a state of a vote in what is supposed to be a states' house, the president is permitted a vote along with other senators (however, that right is rarely exercised); in the case of a tie, the president does not have a casting vote and the motion fails. In the House of Representatives, the Speaker does not vote, but has a

Functions

The principal function of the Parliament is to pass laws, or legislation. Any parliamentarian may introduce a proposed law (a bill), except for a money bill (a bill proposing an expenditure or levying a tax), which must be introduced in the House of Representatives. In practice, the great majority of bills are introduced by ministers. Bills introduced by other members are called private members' bills. All bills must be passed by both houses and assented to by the governor-general to become law. The Senate has the same legislative powers as the House, except that it may not amend or introduce money bills, only pass or reject them. The
enacting formula An enacting clause is a short phrase that introduces the main provisions of a law Entry into force, enacted by a legislature. It is also called enacting formula or enacting words. It usually declares the source from which the law claims to derive ...
for acts of Parliament since 1990 is simply "The Parliament of Australia enacts:". Commonwealth legislative power is limited to that granted in the Constitution. Powers not specified are considered "residual powers", and remain the domain of the states. Section 51 grants the Commonwealth power over areas such as taxation, external affairs, defence and marriage. Section 51 also allows state parliaments to refer matters to the Commonwealth to legislate. Section 96 of the Australian Constitution gives the Commonwealth Parliament the power to grant money to any State, "on such terms and conditions as the Parliament thinks fit". In effect, the Commonwealth can make grants subject to states implementing particular policies in their fields of legislative responsibility. Such grants, known as "tied grants" (since they are tied to a particular purpose), have been used to give the federal parliament influence over state policy matters such as public hospitals and schools. The Parliament performs other functions besides legislation. It can discuss urgency motions or matters of public importance: these provide a forum for debates on public policy matters. Senators and members can move motions on a range of matters relevant to their constituents, and can also move motions of censure against the government or individual ministers. On most sitting days in each house there is a session called question time in which senators and members address questions without notice to the prime minister and other ministers. Senators and members can also present petitions from their constituents. Both houses have an extensive system of committees in which draft bills are debated, matters of public policy are inquired into, evidence is taken and public servants are questioned. There are also joint committees, composed of members from both houses.


Conflict between the houses

In the event of conflict between the two houses over the final form of legislation, the Constitution provides for a simultaneous dissolution of both houses – known as a
double dissolution A double dissolution is a procedure permitted under the Australian Constitution to resolve deadlocks in the bicameral Parliament of Australia between the House of Representatives (lower house) and the Senate (upper house). A double dissolutio ...

, section 57.
In an election following a double dissolution, each state elects their entire 12-seat Senate delegation, while the two territories represented in the Senate each elect their two senators as they would in a regular federal election. Because all seats are contested in the same election, it is easier for smaller parties to win seats under the single transferable vote system: the
quota Quota may refer to: Economics * Import quota, a restriction on the quantity of goods that can be imported into a country * Market Sharing Quota, an economic system used in Canadian agriculture * Milk quota, a quota on milk production in Europe * ...
for the election of each senator in each Australian state in a full Senate election is 7.69% of the vote, while in a normal half-Senate election the quota is 14.28%. If the conflict continues after such an election, the governor-general may convene a joint sitting of both houses to consider the bill or bills, including any amendments which have been previously proposed in either house, or any new amendments. If a bill is passed by an
absolute majority A majority is more than half of a total; however, the term is commonly used with other meanings, as explained in the " Related terms" section below. It is a subset of a set consisting of more than half of the set's elements. For example, if a gr ...
of the total membership of the joint sitting, it is treated as though it had been passed separately by both houses, and is presented for royal assent. With proportional representation, and the small majorities in the Senate compared to the generally larger majorities in the House of Representatives, and the requirement that the number of members of the lower house be "nearly as practicable" twice that of the Senate, a joint sitting after a double dissolution is more likely than not to lead to a victory for the lower house over the Senate. This provision has only been invoked on one occasion, after the

following the 1974 double dissolution. However, there are other occasions when the two houses meet as one.


Committees

In addition to the work of the main chambers, both the Senate and the House of Representatives have a large number of investigatory and scrutiny committees which deal with matters referred to them by their respective houses or ministers. They provide the opportunity for all members and senators to ask questions of witnesses, including ministers and public officials, as well as conduct inquiries, and examine policy and legislation. Once a particular inquiry is completed the members of the committee can then produce a report, to be tabled in Parliament, outlining what they have discovered as well as any recommendations that they have produced for the government or house to consider. The ability of the houses of Parliament to establish committees is referenced in section 49 of the Constitution, which states that,
Constitution of Australia The Constitution of Australia (also known as the Commonwealth Constitution) is the fundamental law that governs the political structure of Australia. It is a written constitution, which establishes the country as a Federation of Australia, ...
, section 49.
Parliamentary committees can be given a wide range of powers. One of the most significant powers is the ability to summon people to attend hearings in order to give evidence and submit documents. Anyone who attempts to hinder the work of a Parliamentary committee may be found to be in contempt of Parliament. There are a number of ways that witnesses can be found in contempt, these include; refusing to appear before a committee when summoned, refusing to answer a question during a hearing or to produce a document, or later being found to have lied to or misled a committee. Anyone who attempts to influence a witness may also be found in contempt. Other powers include, the ability to meet throughout Australia, to establish subcommittees and to take evidence in both public and private hearings. Proceedings of committees are considered to have the same legal standing as proceedings of Parliament, they are recorded by

. Every participant, including committee members and witnesses giving evidence, is protected from being prosecuted under any civil or criminal action for anything they may say during a hearing. Written evidence and documents received by a committee are also protected. Types of committees include: Standing committees, which are established on an ongoing basis and are responsible for scrutinising bills and topics referred to them by the chamber or minister; examining the government's budget and activities (in what is called the budget estimates process); and for examining departmental annual reports and activities. Select committees, which are temporary committees, established in order to consider a particular matter. A select committee expires when it has published its final report on an inquiry. Domestic committees, which are responsible for administering aspects of the Parliament's own affairs. These include the Selection Committees of both Houses that determine how the Parliament will deal with particular pieces of legislation and private members' business, and the Privileges Committees that deal with matters of parliamentary privilege. Legislative scrutiny committees, which examine legislation and regulations to determine their impact on individual rights and accountability. Joint committees are also established to include both members of the House of Representatives and the Senate. Joint committees may be standing (ongoing) or select (temporary) in nature.

. Cabinet meetings are strictly private and occur once a week where vital issues are discussed and policy formulated. The Constitution does not recognise the Cabinet as a legal entity; it exists solely by convention. Its decisions do not in and of themselves have legal force. However, it serves as the practical expression of the Federal Executive Council, which is Australia's highest formal governmental body. In practice, the Federal Executive Council meets solely to endorse and give legal force to decisions already made by the Cabinet. All members of the Cabinet are members of the executive council. The governor-general is bound by convention to follow the advice of the executive council on almost all occasions, giving it de facto executive power. A senior member of the Cabinet holds the office of vice-president of the executive council and acts as presiding officer of the executive council in the absence of the governor-general.

, by giving equal representation to each state. The Constitution intended to give less populous states added voice in a federal legislature, while also providing for the revising role of an upper house in the Westminster system. One of the functions of the Senate, both directly and through its committees, is to scrutinise government activity. The vigour of this scrutiny has been fuelled for many years by the fact that the party in government has seldom had a majority in the Senate. Whereas in the House of Representatives the government's majority has sometimes limited that chamber's capacity to implement executive scrutiny, the opposition and minor parties have been able to use their Senate numbers as a basis for conducting inquiries into government operations. The Constitution prevents the Senate from originating or amending the annual appropriation bills "for the ordinary annual services of the Government"; they may only defer or reject them. As a result, whilst the framers of the Constitution intended that the executive government would require the support of the House of Representatives, the text of the Constitution also effectively allows the Senate to bring down the government once a year by blocking the annual appropriations bills, also known as blocking supply''.'' The ability to block supply was the origin of the

This action in itself was a source of controversy and debate continues on the proper usage of the Senate's ability to block supply and on whether such a power should even exist.

There must be legislation repeatedly blocked by the Senate which the government can then choose to use as a trigger for a double dissolution.

Privileges

Members of the Australian Parliament do not have legal immunity: they can be arrested and tried for any offence. They do, however, have

This privilege extends to reporting in the media of anything a senator or member says in Parliament. The proceedings of parliamentary committees, wherever they meet, are also covered by privilege, and this extends to witnesses before such committees. From the beginning of Federation until 1987, parliamentary privilege operated under section 49 of the Constitution, which established the privileges of both houses and their members to be the same as the

In 1987, the Parliament passed the ''Parliamentary Privileges Act'', which clarified the meaning and extent of privilege as well as how the Parliament deals with breaches. There is a legal offence called contempt of Parliament. A person who speaks or acts in a manner contemptuous of the Parliament or its members can be tried and, if convicted, imprisoned. The Parliament previously had the power to hear such cases itself, and did so in the Browne–Fitzpatrick privilege case, 1955. This power has now been delegated to the courts.
