Why does each branch of government have different responsibilities?

Singapore is a sovereign republic. When it became an independent and sovereign nation in 1965, it inherited a legal system that is based on the English law. The legal system has since evolved to meet the needs of Singapore and to reflect the political system within which it operates. In November 1993, the Application of English Law Act came into force. This Act clarifies the application of English law and statutes in Singapore.

The organs of government are provided for by a written constitution which forms the supreme law of Singapore. The Constitution lays down the fundamental principles and basic framework for the three organs of state, namely, the Executive, the Legislative and the Judiciary. 

The Head of State of Singapore is a President who is directly elected by the people, following fundamental constitutional changes in 1991. The President possesses certain veto powers over the government which the President can exercise with discretion in certain circumstances. Outside of those areas where the Constitution permits the President discretionary powers, the President must act according to Cabinet advice.

The Executive comprises the Cabinet, which is responsible for the general direction of the Government and accountable to Parliament.

The Legislature comprises the Parliament and is the legislative authority responsible for enacting legislation. More information on the history of Parliament, Parliament House and activities of the House can be obtained from its web site.

The Judiciary's function is to independently administer justice. The Judiciary is safeguarded by the Constitution.

The Prime Minister of Singapore is appointed by the President of Singapore under Article 25 of the Constitution. The President, acting on the advice of the Prime Minister, also appoints other Ministers from among the Members of Parliament.

The Prime Minister is the effective head of the executive branch of government. The Prime Minister chairs the Cabinet, which is constituted under Article 24 of the Constitution. The Cabinet is the central decision-making body of the executive government. It is an organ of state and central to Singapore's system of government. In practice, all significant decisions or actions taken by the Executive are first discussed and collectively agreed by Cabinet.

At present, Cabinet comprises the following members:

Mr Lee Hsien Loong Prime Minister
Mr Lawrence Wong
Deputy Prime Minister and Minister for Finance

As the chairman of the Cabinet, the Prime Minister approves the agenda, leads the meetings and oversees the government's general policy direction. The Prime Minister may also determine the setting up of Cabinet committees from time to time to look into specific subject areas, such as national population policies. The responsibilities of the respective ministers are gazetted in separate Gazette Notifications under the Constitution. The web sites of the ministries provide more information on their specific functions and activities.

Why is it important to separate government into multiple branches?

Separation of powers is a model that divides the government into separate branches, each of which has separate and independent powers. By having multiple branches of government, this system helps to ensure that no one branch is more powerful than another.

What are the three branches of government and what are they each responsible for?

These branches are the legislative branch, which makes laws and takes the form of the United States Congress; the executive branch, which enforces the laws and consists of the president and people who report to the president; and the judicial branch, which evaluates laws and includes the Supreme Court and other courts.

What outlined the responsibilities of each branch of government?

The Constitution created the 3 branches of government: The Legislative Branch to make the laws. Congress is made up of two houses, the Senate and the House of Representatives. The Executive Branch to enforce the laws.

Why is it important to have three branches of government why is it important that each branch can check the other branches?

With checks and balances, each of the three branches of government can limit the powers of the others. This way, no one branch becomes too powerful. Each branch “checks” the power of the other branches to make sure that the power is balanced between them.
