The judicial power of the legislature is an example of which kind of institutional power?

1. The Judiciary

The Judiciary includes judges and the courts. The role of the Judiciary is to interpret the law and to judge whether the law applies in individual cases.  When sworn into office, judges make the following oath:

to do right to all manner of people according to law, without fear or favour, affection or ill will

Firstly, the Judiciary administers justices to all manner of people and ensures everyone is treated equally under the law, regardless of their status or rank. They administer justice fairly and openly. The Courts are impartial. They make decisions according to the law, rather than external political pressures, personal, moral, or political views.   As outlined by former Australian High Court Justice Heydon the Judiciary is:

an independent arbiter not affected by self-interest or partisan duty, applying a set of principles, rules and procedures having objective existence and operating in paramountcy to any other organ of state and to any other source of power, and possessing a measure of independence from the wrath of disgruntled governments or other groups  

The Courts are independent from the Executive and Legislature.  The Judiciary has the power to strike down laws made by the Legislature and declare actions of the Executive unlawful. Judicial review ensures the other arms of Government are accountable under the law and are restrained from enacting laws that may be unconstitutional (and therefore invalid and unenforceable) and behaving unlawfully. This is a highly important check on the power of the Government because it provides a legal process in the courts for any individual, not matter their status or rank, to challenge the decisions of the Government.

The Australian Constitution provides a check on the power of the Executive and protects the independence of the Judiciary from political interference by outlining the tenure and remuneration of the Judiciary. This ensures a judge cannot be sacked (or pay reduced) if they make a decision that Government or those in power dislikes.

To ensure the judiciary does not exceed it powers, there is a process of appeal to higher courts. The High Court of Australia has the power to overrule the decisions of all lower Courts.

The Legislature can override a courts interpretation of any ordinary law by passing or amending the law.  This is an important check on the powers of the Judiciary by ensuring the power to make laws is held by elected representatives in Parliament (the Legislature).

2. The Executive

The Executive includes ministers and the government departments, agencies, and statutory bodies they are responsible for. The role of the Executive is to propose (but not pass laws) and then implement laws passed by the Legislature into operation. It has the power to oversee Government Agencies and Departments and deal with social, economic, or environmental issues as they arise.

As the Executive has power to carry out and enforce the law it has the greatest potential of all arms of government for corruption and for exceeding their power. Checks therefore must ensure the Executive acts in accordance with the law and is responsible to Parliament for their actions.

The Judiciary is a critical check on the overuse and misuse of power by the Executive. The Executive is the singly most frequent party in Court proceedings and the Judiciary has the power to determine whether the actions of the Executive are lawful.

Another important check on the power of the Executive is scrutiny by the Legislature and Parliamentary Committees who have the ability to ask the Executive questions in Parliament and to disallow laws passed by the Executive. The Executive is also held accountable by the Shadow Cabinet and the ‘Opposition’ who are frequently critical of Government policy and legislation.

It is important to note that there is only partial separation of powers between the Executive and Legislature in Australia as members of the Executive are drawn from Parliament.

3. The Legislature

The Legislature is an assembly of elected representatives, known as the Parliament, who has the legislative power to make laws. According to Tom Bingham, the Legislature, under the Constitution, may enact any legislation it chooses:

the Parliament has no legislative superior. The courts have no inherent powers to invalidate, strike down, superseded or disregard the provision of an ambiguous statute duly enacted by Parliament and indeed, an extremely limited power to enquire whether a statute has been duly enacted…

A further check on the Legislature is the parliamentary rules and procedures for the passing of laws. For example public readings of the bills and making bills publicly available on the Parliament website enable scrutiny by the public and the media. The bi-cameral system of Government – one which has an Upper and Lower House of Parliament – is a significant check on the power of the Legislature. The important debate and scrutiny of bills within the ‘party room’ slows down over-hasty legislation and enables members of the Legislature to express the views and concerns of those who they represent. It is an important internal check on the power of the Legislature. The Upper House has been described as:

the most important of the constitutional checks on balances on excessive concentration of power…It is the one place where Government can, of right, be questioned and obliged to answer.

– NSW Legislative Practice Chapter 2

Another important check on the power of the Legislature is the ability of the Governor General to dissolve the Legislature, which is only done in exceptional circumstances. The Governor General also must give royal assent to laws passed by the Legislature.

Further, the Constitution balances the law-making power between Federal and State Governments. The Federal Government has the power to legislate with regard to issues such as defence, taxation and immigration, whilst State Governments can make laws in areas such as roads, hospitals, and schools.

Rule of law principles also guide law making. Laws should not be retrospective. This means that once a court decision is handed down, the Legislature cannot then reverse this decision by introducing laws that illegalise actions that were deemed legal at the time by the courts The laws must consider how they delegate power, and must not include arbitrary, overly discretionary or retrospective provisions, be clear, able to be complied with and relatively stable.

Whilst the judiciary is a check to ensure all legislation is lawful, the Legislature also acts as a check on the Judiciary because it can pass laws that override the decisions of the courts.

The principle of the separation of powers distributes the power to govern between the Parliament, the Executive and the Judiciary. This fact sheet examines the role of each group and the related principle of responsible government.

The Australian Constitution is the set of rules by which Australia is run. The first 3 chapters of the Constitution define 3 mostly separate groups—the Parliament, the Executive and the Judiciary—and the roles they play in the governing of Australia. The power to make and manage Australian law is divided between these 3 groups. This division is based on the principle of the 'separation of powers'.

Under this principle, the power to govern should be distributed between the Parliament, the Executive and the Judiciary to avoid any group having all the power. Each group should work within defined areas of responsibility to keep a check on the actions of the others.

Separation of roles

Exceptions to the principle

Australia does not have a complete separation of powers because some of the roles of the Parliament, the Executive and the Judiciary overlap. For example, the Prime Minister and ministers are part of the Executive and the Parliament. High Court judges, the Prime Minister and ministers are officially appointed by the Governor-General, who is part of the Parliament and the Executive.

The role of the Governor-General

Section 61 of the Constitution states that ‘the executive power of the Commonwealth is vested in the Queen and is exercisable by the Governor-General as the Queen’s representative’. This means that the Governor-General has been given certain powers to act on behalf of the Queen. The role of the Governor-General is not just defined by the Constitution; it is also defined by custom and tradition.

While executive power is exercised by the Governor-General, in reality this is normally done on the advice of the Prime Minister and ministers, who have day-to-day responsibility for governing Australia. The Governor-General does not have the authority to make decisions on behalf of the government, but has a role in both the government and the Parliament.

Responsible government

The separation of powers works together with the principle of ‘responsible government’ to guide the way law is made and managed. Responsible government means that a party or coalition of parties must maintain the support of the majority of members of the House of Representatives in order to remain in government. This provides another check on the Executive, ensuring they are accountable to the Parliament and do not abuse their power.

History

The origins of the principle of the separation of powers can be traced back as far as ancient Greece. It was made popular by French philosopher Charles de Montesquieu in his book L'Esprit des Lois (the Spirit of the Laws) (1748). He wrote that a nation's freedom depended on the 3 powers of governance—legislative, executive and judicial—each having their own separate institution. Montesquieu’s ideas have since been widely used in the development of many democratic countries.

This diagram illustrates the separation of powers in the Australian system of government. The Parliament (represented by an icon of Australian Parliament House) has the power to make and change law. The Executive (represented by a group of people) has the power to put law into action. The Judiciary (represented by an icon of a scale) has the power to make judgements on law. The three groups—Parliament, Executive and Judiciary—are connected.
