Getting Started
A legislative system is the institutional framework, including its structures and functions, responsible for debating, creating, and overseeing the implementation of laws. This chapter compares the legislative systems of China, Iran, Mexico, Nigeria, Russia, and the United Kingdom, focusing on how their structures (unicameral vs. bicameral) and functions (lawmaking, oversight, appointments) reflect and reinforce the distribution of political power within each state.
What You Should Be Able to Do
Describe the difference between a unicameral and a bicameral legislature, providing an example of each from the course countries.
Compare the specific powers of the upper and lower houses in the bicameral systems of Mexico, Nigeria, Russia, and the UK.
Explain how the functions of the legislatures in China and Iran differ from those in the democratic course countries.
Contrast the role of an elected legislature (e.g., Mexico's Chamber of Deputies) with an appointed one (e.g., the UK's House of Lords).
Key Developments & Analysis
Comparing Legislative Structures and Executive Relations
| Theme/Dimension | United Kingdom | Russia | China |
|---|---|---|---|
| Structure | Bicameral: An elected House of Commons and an appointed House of Lords. | Bicameral: An elected State Duma and an appointed Federation Council. | Unicameral: A single, party-controlled National People's Congress (NPC). |
| Key Functions | The House of Commons is the primary legislative body, approving legislation. The prime minister is appointed from this body. The House of Lords reviews, amends, and can delay bills. | The Duma passes legislation and confirms the prime minister. The Federation Council approves budgets, treaties, judicial nominees, and troop deployments. | The NPC is constitutionally recognized as the most powerful institution; it elects the president, approves the premier, and legitimizes executive policies. |
| Relationship to Executive Power | The executive (prime minister) is fused with the legislature, drawn from the majority party in the Commons. The legislature sustains the executive in power. | The system is a parliamentary-hybrid. The Duma can be a check on the prime minister but operates under a powerful, separately elected president. | The legislature is controlled by the Chinese Communist Party and serves to legitimize the decisions already made by the party's executive leadership. |
| Why This Matters | The UK's system concentrates power, allowing for efficient policymaking when the executive has a majority. The House of Lords acts as a minor check. Russia's system creates a strong presidency that can dominate a divided legislature. China's system demonstrates the role of a legislature in an authoritarian state: to provide a veneer of legitimacy, not to act as an independent check on power. |
Comparing Legislative Powers in Presidential and Theocratic Systems
| Theme/Dimension | Mexico | Nigeria | Iran |
|---|---|---|---|
| Structure | Bicameral: An elected Chamber of Deputies (lower house) and an elected Senate (upper house). | Bicameral: An elected House of Representatives (lower house) and an elected Senate (upper house). | Unicameral: An elected Majles. |
| Key Functions | The Chamber of Deputies approves legislation, levies taxes, and verifies election outcomes. The Senate confirms Supreme Court appointments, approves treaties, and authorizes federal intervention in states. | Both chambers approve legislation. The Senate holds unique powers of impeachment and confirmation of presidential appointments. | The Majles approves legislation, oversees the budget, and confirms presidential nominees to the Cabinet. Its actions are supervised by the Guardian Council. |
| Relationship to Executive Power | In this congressional-presidential system, the legislature is a separate and co-equal branch designed to check the power of the president through its distinct powers. | Similar to Mexico, this congressional-presidential system features a separation of powers, with the legislature designed to check the executive branch. | In this theocracy, the elected Majles and president operate under the supervision of unelected religious bodies. The Guardian Council can veto legislation to ensure its compatibility with Islam. |
| Why This Matters | The bicameral systems in Mexico and Nigeria create multiple points of access and potential gridlock, forcing negotiation between the chambers and with the president. Iran's system shows how an elected body's power can be severely constrained by an unelected, supreme religious authority, blending democratic and theocratic principles. |

Country Anchors Bank
National People's Congress (China): The constitutionally supreme, unicameral legislature in China. It is a key example of a legislature in a single-party authoritarian state, where its primary function is to legitimize party policy rather than independently create it.
Majles (Iran): The unicameral, elected legislature in Iran. It demonstrates a hybrid system where a popularly elected body has significant powers (budget, legislation) but is ultimately subordinate to an unelected religious authority (the Guardian Council).
Senate (Mexico): The elected upper house of Mexico's bicameral legislature. Its unique powers to confirm Supreme Court justices and approve treaties make it a strong example of checks and balances in a presidential system.
Senate (Nigeria): The elected upper house in Nigeria's bicameral system. Its specific powers of impeachment and confirmation highlight the legislature's role in providing oversight of the executive in a presidential democracy.
Federation Council (Russia): The appointed upper house of Russia's legislature. It exemplifies the power of a non-elected chamber in a hybrid system, holding significant authority over judicial appointments, treaties, and the use of military force.
House of Lords (UK): The appointed upper house in the UK's bicameral parliament. It serves as a key example of an unelected chamber with the power to check the elected lower house by reviewing, amending, and delaying legislation, but not blocking it indefinitely.
Skill Snapshots
Comparison: The legislatures in Mexico and Nigeria are both bicameral and fully elected, designed to check a powerful president, whereas Russia's bicameral legislature mixes an elected lower house with a powerful appointed upper house that often reinforces presidential power.
Comparison: While both Iran and China have unicameral legislatures, Iran's Majles is a site of genuine, though constrained, political debate, while China's National People's Congress acts primarily to affirm decisions made by the Communist Party leadership.
Comparison: The UK's House of Lords and Russia's Federation Council are both appointed upper houses, but the Federation Council holds significant power over foreign policy and appointments, while the House of Lords' power is limited to delaying and revising legislation from the more powerful House of Commons.
Mechanism: In the UK, the fusion of executive and legislative power in the House of Commons → allows for efficient passage of the majority party's legislative agenda.
Mechanism: In Iran, the Guardian Council's supervision of the Majles → ensures that all approved legislation conforms to the state's interpretation of Islamic law, limiting the power of elected officials.
Mechanism: In Mexico, the Senate's unique power to confirm Supreme Court nominees → provides a legislative check on the president's ability to shape the judicial branch.

Common Misconceptions & Clarifications
Misconception: All bicameral systems give equal power to both houses.
- Clarification: Power is often asymmetrical. The UK's House of Commons is far more powerful than the House of Lords, which can only delay, not defeat, legislation.
Misconception: "Elected" means the same thing in all countries.
- Clarification: Elections for China's National People's Congress are controlled by the Communist Party, making it a legitimizing body, unlike the competitive, multi-party elections for Mexico's Congress or Nigeria's National Assembly.
Misconception: Unicameral legislatures are inherently weaker or less democratic than bicameral ones.
- Clarification: Structure does not determine power alone. Iran's unicameral Majles has more substantive influence on policy than China's unicameral NPC. The key factor is the legislature's autonomy from other political institutions.
One-Paragraph Summary
Legislative systems vary significantly across the six course countries, reflecting their different regime types. Democratic states like Mexico, Nigeria, and the UK utilize bicameral legislatures as a mechanism for checking power, though the balance between chambers and their relationship to the executive differs. The UK's parliamentary system fuses the executive and legislature, while Mexico's and Nigeria's presidential systems enforce their separation. In contrast, authoritarian and hybrid systems use legislatures for different purposes. Russia's hybrid system features a powerful appointed upper house that aligns with the president, while China's unicameral NPC serves to legitimize the Communist Party's rule. Iran's unicameral Majles represents a unique case where an elected body exercises real but limited power under the strict supervision of an unelected theocratic council. These variations demonstrate that a legislature's structure—unicameral or bicameral, elected or appointed—is crucial to understanding its actual role in the political process.
