Governments & Parliaments Study Guide

Introduction

A government is the system of institutions and officials through which a state makes decisions, creates and enforces laws, manages public services, collects revenue, and conducts public affairs. A parliament is a type of legislature: an institution that represents people or territories, debates public issues, considers laws, approves public spending, and scrutinizes the executive.

The words government, parliament, president, prime minister, and legislature are often confused. Their meanings also differ between political systems. In some countries, the executive is closely connected to parliament; in others, the executive and legislature are elected separately.

Understanding these distinctions makes it much easier to study constitutions, elections, political institutions, national leaders, and comparative government.

Learning Objectives

After studying this guide, you should be able to:

·         Explain the main functions of government.

·         Distinguish the executive, legislative, and judicial branches.

·         Explain the difference between a government and a parliament.

·         Compare parliamentary, presidential, and semi-presidential systems.

·         Distinguish unicameral and bicameral legislatures.

·         Explain terms such as prime minister, president, cabinet, opposition, coalition, and vote of no confidence.

What Is Government?

The term government can have two related meanings.

In a broad sense, government includes the institutions through which a state exercises public authority.

These commonly include:

·         A legislature

·         An executive

·         Courts and the judiciary

·         Public administration

·         National, regional, and local institutions

In a narrower parliamentary sense, the government usually refers to the executive leadership—such as the prime minister, cabinet, and ministers—rather than parliament as a whole.

For example, the UK Parliament explicitly distinguishes Parliament from the Government. Parliament makes laws and scrutinizes the executive, while the Government runs public administration and develops policy.

The Three Main Branches of Government

Many constitutional systems divide state authority among three broad branches.

Legislative Branch

The legislature makes, debates, amends, and approves laws.

A legislature may be called:

·         Parliament

·         Congress

·         National Assembly

·         Legislative Assembly

·         Diet

·         Majlis

·         Cortes

·         Federal Assembly

The exact name varies by country.

Executive Branch

The executive implements laws and directs the day-to-day administration of the state.

Depending on the political system, executive offices may include:

·         President

·         Prime minister

·         Chancellor

·         Cabinet

·         Ministers

·         Government departments

Judicial Branch

The judiciary interprets and applies law through courts.

Courts may also resolve disputes between individuals, government bodies, or different levels of government. In some constitutional systems, courts can review whether laws or government actions are compatible with the constitution.

The United States provides a well-known example of formal separation among legislative, executive, and judicial branches.

Separation of Powers

Separation of powers means distributing government authority among different institutions rather than concentrating all major powers in one body.

The amount of separation differs between political systems.

In a presidential system, the executive and legislature are usually institutionally separate. In a parliamentary system, there is greater fusion of powers because the head of government and ministers normally depend on support from parliament. International IDEA identifies this relationship with the legislature as a defining feature of parliamentary government.

Checks and Balances

Checks and balances are mechanisms allowing different institutions to limit, review, or oversee one another.

Examples may include:

·         Parliamentary questioning of ministers

·         Legislative approval of budgets

·         Presidential vetoes

·         Judicial review

·         Confirmation of appointments

·         Votes of confidence

·         Investigative committees

The exact mechanisms depend on a country's constitution.

Constitutions

A constitution establishes fundamental rules about how a state is governed.

It commonly describes:

·         Government institutions

·         Distribution of political power

·         Lawmaking procedures

·         Rights and freedoms

·         Relationships between branches

·         Electoral arrangements

·         Procedures for constitutional amendment

International IDEA describes constitutions as higher-law frameworks that typically establish the basic principles, structures, processes, and fundamental rights of a state.

Some countries have a single codified constitutional document, while others rely on several laws, conventions, judicial decisions, and constitutional practices.

The Rule of Law

The rule of law means that public authorities and private persons are subject to law rather than arbitrary power.

The United Nations describes the rule of law as requiring accountability under publicly established and equally enforced laws, together with principles including legal certainty, fairness, transparency, and independent adjudication.

Rule of law should not be confused simply with "having laws." It concerns how laws are created, applied, enforced, and reviewed.

What Is a Parliament?

A parliament is a legislative institution.

Its responsibilities vary, but common parliamentary functions include:

·         Making and changing laws

·         Representing citizens or regions

·         Debating national issues

·         Examining government policy

·         Approving taxation

·         Authorizing public expenditure

·         Questioning ministers

·         Conducting committee investigations

For example, the UK Parliament lists legislation, government scrutiny, debate, and approval of government spending and taxation among its central functions.

Parliament Is Not the Same as Government

This is one of the most important distinctions for quiz questions.

Parliament = legislature

Government = usually the executive administration in parliamentary terminology

Members of the government may also be members of parliament, but the two institutions have different functions. Opposition legislators, independent representatives, and other parliamentarians are not automatically members of the government.

Unicameral and Bicameral Legislatures

Legislatures can be organized into one or two chambers.

Unicameral Legislature

Unicameral means one chamber.

All national legislative business is handled through a single legislative house.

Memory tip:

Uni = one

Bicameral Legislature

Bicameral means two chambers.

International IDEA defines bicameralism as a system in which two assemblies share legislative power. Second chambers can serve purposes such as representing constituent regions, reviewing legislation, or providing an additional institutional check.

Memory tip:

Bi = two

Examples of chamber names include:

The powers of the two chambers are not necessarily equal.

Lower and Upper Houses

In many bicameral legislatures, the two chambers are informally called the lower house and upper house.

A lower chamber is commonly more directly connected to population representation.

An upper chamber may represent:

·         States or provinces

·         Regions

·         Territorial units

·         Different institutional interests

·         Appointed or indirectly elected members

These patterns are common but not universal.

For example, the UK Parliament consists of the elected House of Commons and the House of Lords as its second chamber. Both participate in legislation and scrutiny, although their powers differ.

Parliamentary Systems

In a parliamentary system, the government depends on the confidence or support of parliament, usually its lower chamber.

The prime minister is normally the head of government.

The executive commonly includes:

·         Prime minister

·         Cabinet

·         Ministers

The government usually remains in office only while it can maintain sufficient parliamentary support. Depending on constitutional rules, parliament may be able to remove a government through a vote of no confidence.

Majority Government

A majority government occurs when the governing party or governing alliance controls enough legislative seats to command a majority.

Minority Government

A minority government lacks a legislative majority of its own but remains in office because it receives enough support or tolerance from other legislators to survive key votes.

Coalition Government

A coalition government forms when two or more political parties cooperate to govern.

Coalitions are particularly common where electoral systems produce parliaments containing several significant parties.

Presidential Systems

In a presidential system, the president generally serves as head of the executive independently of the legislature.

The president and legislature normally have separate constitutional mandates.

A president usually serves for a constitutionally defined term and is not ordinarily removed simply because the legislature disagrees with government policy. Removal procedures such as impeachment are different from an ordinary parliamentary vote of no confidence.

The United States is a prominent example: Congress forms the federal legislative branch, while executive authority belongs to a separately constituted presidency.

Semi-Presidential Systems

A semi-presidential system combines elements of presidential and parliamentary government.

It normally contains both:

·         A president

·         A prime minister

Executive responsibilities are divided between them according to constitutional rules.

The prime minister and government typically depend on parliamentary support, while the president has a separate constitutional position. The exact balance of authority can vary substantially between countries.

Parliamentary vs Presidential Systems

These are general patterns. Individual constitutions can create important exceptions.

Head of State vs Head of Government

Another common quiz distinction involves the difference between the head of state and head of government.

Head of State

The head of state formally represents the state.

Possible titles include:

·         President

·         King

·         Queen

·         Emperor

Head of Government

The head of government directs the executive's political and administrative work.

Common titles include:

·         Prime minister

·         Chancellor

·         President

In many parliamentary systems, the positions are held by different people.

For example:

Head of state: monarch or president
Head of government: prime minister

In many presidential systems, one president serves as both head of state and head of government.

Monarchy and Republic

These terms describe the office of head of state rather than the entire structure of government.

Monarchy

In a monarchy, the head of state is a monarch, such as a king or queen.

In a constitutional monarchy, the monarch's authority is limited by constitutional arrangements. In contemporary parliamentary constitutional monarchies, the monarch may perform primarily representative and ceremonial functions rather than direct policymaking.

Republic

A republic has a non-hereditary head of state, normally called a president.

A republic can have:

·         A presidential system

·         A parliamentary system

·         A semi-presidential system

Therefore:

Republic does not automatically mean presidential system.

Likewise:

Monarchy does not automatically mean absolute monarchy.

Federal and Unitary Systems

Countries can also be classified according to how authority is divided territorially.

Federal System

In a federal system, constitutional authority is divided between a central or federal government and constituent units such as states, provinces, or regions.

International IDEA describes federalism as combining constitutionally protected self-government at one level with shared government at another.

Unitary System

In a unitary system, ultimate constitutional authority is concentrated at the national level.

Local or regional authorities may still possess substantial powers, but these powers operate within the constitutional structure of the unitary state.

Do not confuse:

Federal vs unitary = territorial distribution of authority.

Parliamentary vs presidential = relationship between executive and legislature.

A country can therefore be both federal and parliamentary, or federal and presidential.

How a Bill Becomes a Law

The exact legislative procedure differs by country, but a simplified parliamentary process often follows this sequence:

Idea → Bill → Debate → Committee Review → Amendments → Vote → Other Chamber if required → Formal Approval → Law

Bill

A bill is a proposed law.

Committee

A parliamentary committee is a smaller group of legislators that examines legislation, government activities, budgets, or particular policy areas in greater detail.

Amendment

An amendment is a proposed change to a bill or other legislative text.

Act

Once a bill completes the required constitutional stages and becomes law, it may be called an Act or statute.

Parliamentary Scrutiny

Parliaments do more than pass laws.

Scrutiny means examining and questioning the actions of government.

Common scrutiny mechanisms include:

·         Questions to ministers

·         Parliamentary debates

·         Committee hearings

·         Investigations

·         Budget examination

·         Government reports

·         Confidence procedures

The UK Parliament, for example, uses ministerial questions, debates, and committee investigations as important methods of government scrutiny.

Government and Opposition

In many parliamentary systems, legislators are divided between supporters of the government and opposition parties.

Government

The governing party or coalition supports the executive.

Opposition

The opposition consists of political parties and legislators that are not part of the government.

Its parliamentary activities can include:

·         Questioning ministers

·         Criticizing government proposals

·         Proposing alternatives

·         Examining legislation

·         Participating in committees

The precise rights and formal status of opposition parties vary considerably across political systems.

Speaker or Presiding Officer

A parliament normally has an official responsible for presiding over legislative proceedings.

Possible titles include:

·         Speaker

·         President of the Senate

·         President of Parliament

·         Chairperson

Typical responsibilities include:

·         Managing debates

·         Applying parliamentary rules

·         Recognizing members who wish to speak

·         Maintaining order

·         Announcing voting results

The exact authority and political neutrality expected of the presiding officer differs between legislatures.

Elections and Representation

Legislators may be selected under different electoral systems.

Three broad categories commonly encountered in general civics are:

Plurality or Majority Systems

Candidates generally compete to win constituencies or districts.

Proportional Representation

Seats are allocated partly or mainly according to the proportion of votes received by political parties or lists.

Mixed Systems

Mixed electoral systems combine elements of district-based and proportional representation.

Electoral systems can influence the composition of parliament, party competition, and coalition formation, but their effects also depend on political and constitutional context.

Important Government Vocabulary

Common Mistakes

Government and Parliament Are Not Synonyms

Parliament is the legislature. In parliamentary terminology, the government normally refers to the executive leadership.

President Does Not Always Mean Head of Government

Some presidents mainly serve as heads of state while a prime minister leads the government.

Republic Does Not Mean Presidential System

Parliamentary republics also exist.

A Prime Minister Is Not Normally Directly Equivalent to a President

Their constitutional roles depend on the political system.

Bicameral Does Not Mean Two Political Parties

Bicameral = two legislative chambers.

Federal Does Not Mean Presidential

Federalism concerns the division of authority between levels of government, not whether the executive is presidential or parliamentary.

Upper House Does Not Always Mean More Powerful

"Upper" and "lower" describe chambers, not necessarily their relative political power.

Memory Tips

Use these simple associations:

Legislature → legislates → makes laws

Executive → executes → carries out laws and policy

Judiciary → judges → interprets and applies law

Uni → one chamber

Bi → two chambers

Prime minister → usually parliamentary government

President → role depends on the constitution

Coalition → several parties cooperate

No confidence → parliament tests support for government

Federal → power divided constitutionally between levels

Summary

Governments organize public authority through institutions such as executives, legislatures, courts, and public administrations. A constitution establishes many of the fundamental rules governing how these institutions interact.

Parliaments are legislatures. Their major functions commonly include lawmaking, representation, debate, scrutiny, and control over taxation and public expenditure.

Political systems organize executive and legislative authority differently. Parliamentary governments depend on legislative confidence, presidential systems provide greater institutional separation between executive and legislature, and semi-presidential systems combine a president with a prime minister who operates within a parliamentary relationship.

Other classifications describe different questions. Unicameral and bicameral refer to the number of legislative chambers. Federal and unitary describe territorial divisions of authority. Monarchy and republic describe the nature of the head of state.

Keeping these classifications separate is one of the easiest ways to master government and parliament questions.
