Constitutional change under Labour 1997-2010

  • The uncodified and unentrenched nature of the UK constitution means that it is highly flexible and capable of evolving over time

  • Since 1997, successive governments have introduced significant constitutional reforms, both expanding and, in some cases, rolling back earlier developments

1. House of Lords Act (1999)

What it did

  • Removed all but 92 of the House of Lords' hereditary peers

  • Introduced a much larger appointed element of life peers

Why it was introduced

  • To modernise the House of Lords

  • To increase its legitimacy by adding expertise rather than inherited membership

Impact

  • The House of Lords became more politically balanced

  • It also became more willing to challenge the House of Commons, although the Commons remains supreme under the Parliament Acts

Problems

  • The House of Lords remains unelected

    • Most notably, 92 hereditary peers and 26 Lords Spiritual remain

      • In 2024, Conservative MP and former minister Gavin Williamson suggested that all Lords Spiritual should be removed from the House of Lords

  • The legitimacy of the House of Lords continues to be questioned due to its unelected nature

Case Study

The House of Lords and the Rwanda Bill

  • In 2024, the House of Lords raised significant objections to the Rwanda Bill, particularly over whether Rwanda could be considered a ‘safe’ country for people awaiting asylum decisions

  • Many peers argued that the policy raised concerns about human rights and international law

The impact of the House of Lords

  • The Lords used its powers to delay and amend the legislation, forcing the government to reconsider parts of the Bill and justify its policy more clearly

  • Although the House of Commons ultimately had the final say, the Lords acted as an effective scrutinising chamber

2. Northern Ireland devolution: Good Friday Agreement (1998)

What it did

  • Created a power-sharing Assembly and Executive in Northern Ireland

Why it was introduced

  • Northern Ireland had experienced decades of conflict known as The Troubles

  • The Agreement aimed to bring an end to violence through inclusive, power-sharing government

  • Unionist parties such as the DUP and nationalist parties such as Sinn Féin were required to participate for a government to be formed

Impact

  • Northern Ireland saw a return to local governance, supported by a popular referendum approving the Agreement

Problems

  • There have been repeated suspensions of the Northern Ireland Assembly

    • These include suspensions from 2017–2020 over the Renewable Heat Incentive scandal and 2022–2024 over post-Brexit arrangements

  • During suspensions, Northern Ireland is once again governed directly from Westminster

3. Welsh devolution: Government of Wales Act (1998)

What it did

  • Created the Welsh Assembly with secondary legislative powers

Why it was introduced

  • There was demand for greater regional decision-making in Wales

  • It also followed the decision to grant devolution to Scotland

Impact

  • The Welsh Assembly introduced distinctive policies, such as removing school league tables and scrapping SATs for primary school pupils

Problems

  • Welsh devolution created asymmetrical devolution, as Wales and Scotland were granted different powers

  • Wales initially lacked primary legislative powers

  • Turnout in the referendum was only around 50%, and of those voters, only just over half supported the creation of the Assembly

3. Scottish devolution: Scotland Act (1998)

What it did

  • Created the Scottish Parliament at Holyrood

  • Granted primary legislative powers and limited tax-varying powers

Why it was introduced

  • Recognised Scotland’s distinct political identity

  • Reflected dissatisfaction with long periods of Conservative rule from Westminster, despite limited Conservative support in Scotland

Impact

  • Significant policy divergence from the rest of the UK

    • Examples include banning smoking, banning smacking, and abolishing tuition fees for Scottish students

  • The success of some Scottish policies, such as the smoking ban, later influenced UK-wide legislation

Problems

  • The West Lothian Question, as Scottish MPs at Westminster continued to vote on England-only matters

  • Rather than reducing support for independence, devolution arguably strengthened it, contributing to the 2014 independence referendum

4. Human Rights Act (1998)

What it did

  • Incorporated the European Convention on Human Rights (from the Council of Europe, not the EU) into UK law

Why it was introduced

  • Allowed individuals to enforce their rights in UK courts rather than taking cases to the European Court of Human Rights in Strasbourg

Impact

  • UK courts can issue declarations of incompatibility, formally stating that legislation conflicts with human rights

  • Increased domestic protection of individual rights

Problems

  • As an Act of Parliament, the Human Rights Act can be repealed due to parliamentary sovereignty

  • Since 2015, the Conservative Party has proposed replacing it with a British Bill of Rights

  • It has not prevented human rights abuses, for example:

    • The Terrorism Act 2006, which allowed 28-day detention without charge

    • A parliamentary committee found the Rwanda Bill (2024) to be incompatible with human rights obligations

5. Constitutional Reform Act (2005)

What it did

  • Created the UK Supreme Court, replacing the Law Lords in the House of Lords

Why it was introduced

  • To strengthen separation of powers

  • To increase judicial independence

Impact

  • Clearer separation between the judiciary and legislature

  • The Supreme Court became the highest appellate court in the UK

  • The Court has ruled against the government in key cases, including Miller v Brexit Secretary (2017) and Miller v Prime Minister (2019)

Problems

  • Parliamentary sovereignty means Parliament can legislate to override judicial rulings

  • The government retains influence over judicial appointments, meaning separation is not complete

Case Study

What happened?

  • In 2019, the Supreme Court ruled in Miller v Prime Minister that Prime Minister Boris Johnson’s decision to prorogue Parliament was unlawful

    • Parliament had been suspended for five weeks during the Brexit process, limiting MPs’ ability to scrutinise the government

  • The Court judged that prorogation was unlawful because it prevented Parliament from carrying out its constitutional role without reasonable justification

  • As a result, Parliament was immediately recalled

Constitutional significance

  • This case was constitutionally significant because it showed that:

    • The courts can review the use of executive power, even when it involves royal prerogative

    • Parliamentary sovereignty must be protected from executive overreach

    • The Supreme Court acts as a constitutional safeguard, despite the UK not having a codified constitution
