Welcome to Comparative Government: Republic of Ireland and the UK!

Welcome to Unit A2 1: Option B! In this module, we will explore how power is structured, exercised, and limited across two neighboring systems: the Republic of Ireland (ROI) and the United Kingdom (UK).

Comparative politics is simply about placing two systems side by side to see what they have in common, where they differ, and why those differences matter. Don't worry if political terminology feels overwhelming at first—we will break down every concept step by step.

Section 1: The Legislative Branch

The legislative branch is the law-making body of a state. Both the Republic of Ireland and the United Kingdom have bicameral systems (which means they have two separate chambers or "houses").

1. Structure of the Legislatures

  • Republic of Ireland (The Oireachtas): Made up of the lower house, Dáil Éireann, and the upper house, Seanad Éireann.
  • United Kingdom (Parliament): Made up of the lower house, the House of Commons, and the upper house, the House of Lords.

2. Electoral Systems: How Representatives Get Elected

The way politicians are elected has a massive impact on the kind of government a country gets.

  • Republic of Ireland (Dáil Éireann): Uses Proportional Representation with Single Transferable Vote (PR-STV).
    How it works: Voters rank candidates in multi-seat constituencies in order of preference (1, 2, 3...).
    Outcome: Seats closely reflect the percentage of votes cast. This proportional nature makes coalition governments (two or more parties working together) the normal outcome in Ireland.
  • United Kingdom (House of Commons): Uses First Past the Post (FPTP).
    How it works: Voters choose one candidate in a single-seat constituency. The candidate with the most votes wins, even if they don't have an absolute majority.
    Outcome: This plurality system tends to exaggerate the lead of the largest party, historically producing single-party majority governments with strong working majorities.

3. Functions and Efficiency

Both Dáil Éireann and the House of Commons share three core functions:

  1. Legislation: Debating, amending, and passing laws.
  2. Scrutiny: Holding the executive (the government) to account for its actions and spending.
  3. Representation: Voicing the concerns of constituents and citizens.

Efficiency Comparison:

  • In the UK House of Commons, a single-party government with a secure majority can pass legislation relatively quickly, but scrutiny can sometimes be weakened if backbench MPs strictly follow party orders.
  • In Dáil Éireann, coalition politics and the presence of independent TDs often require more compromise, debate, and consensus-building to pass legislation.

Quick Review: Legislative Branch

Remember this simple comparison formula:
ROI: Oireachtas (Dáil + Seanad) \(\rightarrow\) PR-STV \(\rightarrow\) Coalitions are normal.
UK: Parliament (Commons + Lords) \(\rightarrow\) FPTP \(\rightarrow\) Single-party majorities have historically been the norm.

Section 2: The Executive Branch

The executive branch is responsible for running the country day-to-day, formulating policy, and putting laws into effect.

1. Heads of State vs. Heads of Government

It is crucial not to mix up who leads the country symbolically (the Head of State) and who actually runs the political show (the Head of Government).

  • Heads of State (Ceremonial Roles):
    • ROI: The President of Ireland (Uachtarán na hÉireann) is an elected figure who acts primarily as a ceremonial head of state with limited reserve powers.
    • UK: The Monarch is a hereditary constitutional monarch performing ceremonial duties.
  • Heads of Government (Political Leaders):
    • ROI: The Taoiseach (Prime Minister), who is formally nominated by Dáil Éireann and appointed by the President.
    • UK: The Prime Minister, appointed by the Monarch based on their ability to command a majority in the House of Commons.

2. Cabinet Systems and Executive Power

Both countries use a Cabinet system, where senior ministers head government departments (e.g., Finance/Treasury, Foreign Affairs, Health):

  • Cabinet in Ireland: The Taoiseach selects ministers from members of the Oireachtas to form the Government. Decisions are made collectively.
  • Cabinet in the UK: The Prime Minister chooses Cabinet ministers primarily from the House of Commons (and occasionally the Lords) to lead central government departments.

3. Holding the Executive to Account

Both parliaments have established mechanisms to prevent the executive from acting without checks:

  • Parliamentary Questions (PQs): In both jurisdictions, ministers and the head of government must answer questions on the floor of the house (e.g., Leaders' Questions in the Dáil; Prime Minister's Questions / PMQs in the Commons).
  • Committee Scrutiny:
    • ROI: Oireachtas Committees examine department expenditure, scrutinise draft bills, and question ministers and civil servants.
    • UK: Select Committees in the House of Commons monitor each major government department, producing detailed reports and holding public evidence sessions.

Key Takeaway: While both systems use a cabinet-style government answerable to an elected lower house, their heads of state differ in origin (an elected President in Ireland vs. a hereditary Monarch in the UK), though both serve largely ceremonial functions.

Section 3: Comparative Politics (Key Comparison Areas)

1. Constitutions: Written vs. Uncodified

A constitution sets out the rules of the political game.

  • Republic of Ireland — Codified Constitution:
    • Governed by Bunreacht na hÉireann (enacted in 1937).
    • It is a single, written (codified) document with legal supremacy over all other laws.
    • How it changes: Any constitutional amendment must be approved by the public in a national referendum. Ordinary legislation cannot alter it.
  • United Kingdom — Uncodified Constitution:
    • The UK has an uncodified constitution made up of multiple sources: statute law (Acts of Parliament), common law, constitutional conventions, works of authority, and treaties.
    • How it changes: Amendments are made through regular legislative Acts of Parliament. There is no special process or mandatory referendum required to change constitutional rules.

2. The Judiciary and Judicial Review

The power of the courts to check the legislature and executive is one of the most critical comparative points between the two systems.

Feature Republic of Ireland (Supreme Court) United Kingdom (Supreme Court)
Highest Court The Supreme Court of Ireland The Supreme Court of the United Kingdom (established 2009)
Constitutional Rule Constitutional Supremacy: The written constitution is the highest law of the land. Parliamentary Sovereignty: Parliament is the supreme legal authority and can make or unmake any law.
Power over Primary Legislation Can strike down laws: Possesses full judicial review powers to declare an Act of the Oireachtas void and unconstitutional if it violates Bunreacht na hÉireann. Cannot strike down primary legislation: Due to Parliamentary Sovereignty, the UK Supreme Court can review government actions and secondary rules, or issue a "declaration of incompatibility" under the Human Rights Act, but it cannot strike down primary Acts of Parliament.

Common Pitfalls to Avoid in the Exam

  • Pitfall 1: Applying Parliamentary Sovereignty to Ireland. In the UK, Parliament is supreme. In Ireland, the Constitution is supreme. If an Irish law breaches Bunreacht na hÉireann, the Supreme Court can strike it down.
  • Pitfall 2: Treating the Irish President like the US President. The President of Ireland is not the political executive. The Taoiseach leads the government; the President performs largely ceremonial and constitutional functions.
  • Pitfall 3: Forgetting the electoral connection. When writing essays, always connect the electoral system to the outcome: PR-STV \(\implies\) coalition governments; FPTP \(\implies\) single-party majority governments.
