Powers not granted to the Federal government are reserved for States and the people, which are divided between State and local governments.
Most Americans have more frequent contact with their State and local governments than with the Federal Government. Police departments, libraries, and schools—not to mention driver’s licenses and parking tickets—usually fall under the oversight of State and local governments. Each state has its own written constitution, and these documents are often far more elaborate than their Federal counterpart. The Alabama Constitution, for example, contains 310,296 words—more than 40 times as many as the U.S. Constitution.
All State governments are modeled after the Federal Government and consist of three branches: executive, legislative, and judicial. The U.S. Constitution mandates that all States uphold a “republican form” of government, although the three-branch structure is not required.
Executive Branch
In every state, the Executive Branch is headed by a governor who is directly elected by the people. In most states, other leaders in the executive branch are also directly elected, including the lieutenant governor, the attorney general, the secretary of state, and auditors and commissioners. States reserve the right to organize in any way, so they often vary greatly with regard to executive structure.
Legislative Branch
All 50 States have legislatures made up of elected representatives, who consider matters brought forth by the governor or introduced by its members to create legislation that becomes law. The legislature also approves a State’s budget and initiates tax legislation and articles of impeachment. The latter is part of a system of checks and balances among the three branches of government that mirrors the Federal system and prevents any branch from abusing its power.
Except for one State, Nebraska, all States have a bicameral legislature made up of two chambers: a smaller upper house and a larger lower house. Together the two chambers make State laws and fulfill other governing responsibilities. (Nebraska is the lone state that has just one chamber in its legislature.) The smaller upper chamber is always called the Senate, and its members generally serve longer terms, usually four years. The larger lower chamber is most often called the House of Representatives, but some states call it the Assembly or the House of Delegates. Its members usually serve shorter terms, often two years.
Judicial Branch
State judicial branches are usually led by the State supreme court, which hears appeals from lower-level State courts. Court structures and judicial appointments/elections are determined either by legislation or the State constitution. The supreme court focuses on correcting errors made in lower courts and therefore holds no trials. Rulings made in State supreme courts are normally binding; however, when questions are raised regarding consistency with the U.S. Constitution, matters may be appealed directly to the United States Supreme Court.
Local Government
Local governments generally include two tiers: counties, also known as boroughs in Alaska and parishes in Louisiana, and municipalities, or cities/towns. In some States, counties are divided into townships. Municipalities can be structured in many ways, as defined by State constitutions, and are called, variously, townships, villages, boroughs, cities, or towns. Various kinds of districts also provide functions in local government outside county or municipal boundaries, such as school districts or fire protection districts.
Municipal governments—those defined as cities, towns, boroughs (except in Alaska), villages, and townships—are generally organized around a population center and in most cases correspond to the geographical designations used by the United States Census Bureau for reporting of housing and population statistics. Municipalities vary greatly in size, from the millions of residents of New York City and Los Angeles to the few hundred people who live in Jenkins, Minnesota.
Municipalities generally take responsibility for parks and recreation services, police and fire departments, housing services, emergency medical services, municipal courts, transportation services (including public transportation), and public works (streets, sewers, snow removal, signage, and so forth).
Whereas the Federal Government and State governments share power in countless ways, a local government must be granted power by the State. In general, mayors, city councils, and other governing bodies are directly elected by the people.
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.
