How Laws Are Passed in Different Government Systems

World Reporter Staff

Creating and enacting laws is one of the primary functions of government, ensuring stability and regulation in society. However, the way laws are passed differs significantly across various government structures. Whether it’s a presidential, parliamentary, federal, or unitary system, each model has its own process for introducing, debating, and enacting laws. Understanding these differences helps to comprehend how policies are made and the role of various branches of government in shaping national legal landscapes.

What Is the Legislative Process?

The legislative process is the formal procedure through which a proposed law, or bill, is introduced, debated, amended, and passed by the legislature. While the specific steps vary based on the government structure, most countries follow a similar sequence:

Proposal and Drafting: A bill is introduced by lawmakers or government officials.
Committee Review: The bill is reviewed and amended by relevant legislative committees.
Debate and Voting: Lawmakers debate the bill before voting on it.
Executive Approval or Veto: The bill is sent to the executive branch for approval or veto.
Implementation and Judicial Review: Once passed, the bill becomes law and is implemented, with the judiciary potentially reviewing its constitutionality.

How Laws Are Passed in a Presidential System

In a presidential system, such as in the United States or Brazil, the executive and legislative branches operate independently. This separation ensures that both branches have distinct roles in the lawmaking process:

Bill Introduction: A legislator, typically from the lower house of Congress, introduces the bill.
Committee Review: The bill is sent to committees in both legislative chambers for scrutiny, debate, and amendments.
Debate and Voting: After review, the bill is debated and voted on by both chambers of the legislature.
Executive Approval: If both chambers approve the bill, it is sent to the president, who can sign it into law or veto it. A veto can be overridden by a supermajority vote in Congress.

The presidential system emphasizes a separation of powers, ensuring that no branch holds too much influence over the lawmaking process.

How Laws Are Passed in a Parliamentary System

In parliamentary systems, like in the United Kingdom, Canada, and India, the executive is part of the legislature, meaning that the head of government (Prime Minister) is also a member of the legislature. This unified structure often leads to faster lawmaking processes:

Bill Introduction: Bills can be introduced by any member of Parliament, often a government minister.
Committee and Debates: Bills undergo committee review and extensive debate.
Voting and Passage: After debates and potential amendments, the bill is voted on by Parliament. In most cases, the ruling party’s majority allows for quicker passage.
Final Approval: In bicameral parliamentary systems, the bill moves to the upper house for approval. In some cases, the head of state, such as a monarch or president, provides formal assent to make the law official.

Because the executive and legislative branches are connected, the lawmaking process is typically faster and more cohesive, with the government having more influence on the passage of laws.

How Laws Are Passed in a Federal System

In federal systems, such as in Germany, Australia, or the United States, lawmaking occurs at both the national and regional levels. These systems distribute legislative power between national governments and subnational entities (such as states or provinces), leading to a more complex process:

National Laws: Proposed laws are introduced at the national level and debated in the national legislature.
State/Regional Laws: In addition to national laws, states or provinces have their own legislatures that create laws at the regional level.
Bicameral Approval: In federal systems, laws typically need to pass both houses of the national legislature, often with separate review by regional entities.

Federal systems ensure that local governments have autonomy in passing laws while maintaining national coherence in governance.

How Laws Are Passed in a Unitary System

In unitary governments, such as in France, China, or Japan, all legislative power is concentrated in the central government. Unlike federal systems, unitary states do not have independent regional legislatures, and laws are passed by a single central authority:

Centralized Lawmaking: In unitary systems, all laws are introduced and passed by the central government or legislature.
Limited Regional Influence: Local governments may administer laws but do not pass them independently.
Quicker Implementation: The lack of regional legislative bodies allows for faster passage and implementation of laws.

Unitary systems are often more streamlined and efficient in lawmaking but may limit local representation in policy creation.

What Role Does the Judiciary Play in Lawmaking?

Regardless of the system, the judiciary plays an essential role in interpreting and enforcing laws. Courts may:

Interpret Legislation: Clarify the meaning and application of laws in specific cases.
Strike Down Unconstitutional Laws: In many systems, courts can review laws for compliance with the constitution and may invalidate laws that violate fundamental rights.
Ensure Government Compliance: Courts ensure that the government follows the laws and does not overstep its constitutional powers.

The judiciary ensures that laws remain in line with constitutional principles and protects citizens from potential government overreach.

Laws are created and passed differently depending on the government structure, with distinct processes in presidential, parliamentary, federal, and unitary systems. Each system reflects its political framework and the balance of power between branches of government. Whether through a separated executive and legislative branch, a unified parliamentary system, a dual-level federal structure, or a centralized unitary state, the legislative process plays a vital role in shaping how societies govern and create laws. Understanding these structures provides clarity on how policies are created and how different countries adapt their systems to meet the needs of their populations.
