Checks and balances: what are they, and why do they matter?

Checks and balances are fundamental elements of constitutional democracy that prevent the unconstrained exercise of power, improve the quality of decision-making and ensure that mechanisms exist for preventing or penalising unethical behaviour. Lisa James, Alan Renwick and Meg Russell argue that they therefore play a vital role in maintaining public confidence in the political system and the government has a particular responsibility to uphold them.

Background

The importance of checks and balances is often cited in debates about the health of democracy, and their erosion is widely considered a sign of democratic backsliding. But what are they, and why are they important?

Checks and balances are the mechanisms which distribute power throughout a political system – preventing any one institution or individual from exercising total control. The words ‘checks’ and ‘balances’ are typically used together, but can be thought of as referring to subtly different (though overlapping) things. Checks are the mechanisms which allow political institutions to limit one another’s power – for example by blocking, delaying or simply criticising decisions. Balances, meanwhile, ensure that a wide variety of views and interests are represented in the democratic process. This includes structures like federalism, or broader features of democratic functioning such as the existence of multiple political parties.

The term ‘checks and balances’ is given more prominence in some countries than others, and is often particularly associated with the United States. But the principle is core to all modern democracies.

Checks and balances operate between and within most political institutions. However, the risks of unconstrained power are often considered particularly high with respect to the executive. This briefing hence focuses on the key institutions which check and balance executive power at UK level:

  1. parliament
  2. the courts
  3. impartial officials, and
  4. media and civil society.

Why do checks and balances matter?

Checks and balances play two key roles. First, they limit the power of the majority to act without regard to the views or interests of others. They ensure that the perspectives of those who are in the minority on a given issue are represented – for example, by guaranteeing that opposition voices are heard in the process of law-making. Second, at a more practical level, they ensure that policy is tested and behaviour supervised. This helps to improve the quality of decision-making, and prevent behaviour which might threaten the integrity or reputation of the political system.

The rule of law: what is it, and why does it matter?

The rule of law is a fundamental principle underpinning the UK constitution. Its core principles include limits on state power, protection for fundamental rights and judicial independence. Lisa James and Jan van Zyl Smit argue that upholding the rule of law is a responsibility shared between politicians, officials and the public – with ministers and MPs having important roles to play.  

Background

The rule of law is frequently cited in political debate, and is a key topic monitored by those worried about democratic backsliding. But what is it, and why is it so important?

The rule of law is one of the fundamental principles underpinning constitutional democracies, and its importance is not seriously questioned in any modern democratic state. But like other constitutional principles, long-running debates exist about how it can most effectively be implemented.

This briefing explains the central concepts constituting the rule of law under three broad categories:

  1. Legality and legal certainty
  2. Legal equality and fundamental rights
  3. Judicial independence and access to justice

Why does the rule of law matter?

The rule of law prevents the abuse of state power, requires the law to be followed by all, and ensures that legal rights are fulfilled in practice. It also provides the means for various other core aspects of democracy to be safeguarded – for example, making certain that the laws made by parliament are enforced, and that fair conduct of elections can be guaranteed. More broadly, it underpins social functioning by providing fair and legitimate routes for disputes to be settled. And it supports stable economies and economic growth by upholding property rights, facilitating the elimination of corruption, and maintaining a business environment in which contracts are enforced, and international trade and investment can flourish. The rule of law alone is not sufficient to make a state democratic, but a state which does not observe it cannot be a healthy democracy.

As such, the rule of law has long been recognised as a fundamental part of the UK system. Many of its core aspects were established during the seventeenth century – particularly by the Bill of Rights 1689. Nineteenth-century scholar Albert Venn Dicey considered it, alongside parliamentary sovereignty, one of the ‘twin pillars’ of the constitution. More recently, Margaret Thatcher considered its observance central to Conservatism, arguing that ‘the institution of democracy alone is not enough. Liberty can only flourish under a rule of law’. And the 2001 Labour government recognised its importance as an existing principle in the Constitutional Reform Act 2005.

What does the rule of law cover?

Like other fundamental principles, the precise details of the rule of law are debated, but its central tenets are widely recognised. Lord (Tom) Bingham of Cornhill, a former Senior Law Lord, provided one well-known schema, on which the Venice Commission’s Rule of Law tools for assessing constitutional reforms are based. Another influential definition was given by then UN Secretary-General Kofi Annan, who defined the rule of law as:

…a principle of governance in which all persons, institutions and entities, public and private, including the State itself, are accountable to laws that are publicly promulgated, equally enforced and independently adjudicated, and which are consistent with international human rights norms and standards.

Parliament’s watchdogs: independence and accountability of five constitutional regulators

The Unit today published a new report, Parliament’s Watchdogs: Independence and Accountability of Five Constitutional Regulators. Robert Hazell explains that public awareness of these regulators is low and the position of some of them in public life is precarious. He calls for several measures, including putting the CSPL on a statutory footing, protecting watchdogs from dismissal, and repealing the legislation allowing the government to produce a strategy statement for the Electoral Commission.

Origins of this study

The constitutional reforms of the last 25 years have seen an upsurge in the number of constitutional watchdogs. The Constitution Unit anticipated these developments from the start, with an early report on constitutional watchdogs in 1997 (Unit report no. 10). This interest was continued by Oonagh Gay and Barry Winetrobe, who wrote two major reports on watchdogs: Officers of Parliament: Transforming the Role (Unit report no. 100, 2003) and Parliament’s Watchdogs: At the Crossroads(Unit report no. 144, 2008).

Today sees the launch of a new report, Parliament’s Watchdogs: Independence and Accountability of Five Constitutional Regulators, (Unit report 195), by Marcial Boo, Zach Pullar and myself. Marcial Boo, former Chief Executive of IPSA, joined the Constitution Unit in late 2020 as an honorary research fellow. We asked him to do a study of those watchdogs which are directly sponsored by parliament, working with Zach Pullar, a young law graduate who has since become a Judicial Assistant in the Court of Appeal. There is an obvious tension with watchdogs whose role is to scrutinise the executive (like the Independent Adviser on Ministers’ Interests), being themselves appointed and sponsored by the government. Less obvious, but just as fundamental, is the tension for watchdogs whose role is to regulate the behaviour of parliamentarians, being themselves appointed and sponsored by parliament.

After an unsuccessful legal challenge by All the Citizens and the Good Law Project, where next on WhatsApp use in government?

Cassandra Somers-Joce and Joe Tomlinson discuss the use of instant messaging technologies within government, arguing that good government does not mean the eradication of such technology from government practice, but that it must be used in a way that is sensitive to the state’s duties to maintain a record.

The last few years have seen several prominent examples of instant messaging technologies – some with the capacity to auto-delete messages – being used within the UK government. Examples ranging from the articulation of the rationale behind the controversial prorogation of parliament to the securing of government medical device contracts during the COVID-19 pandemic have arisen in the press. Instant messaging technologies clearly play an important role in government communication and decision-making. These technologies are seemingly utilised daily across all levels; for instance, the BBC has reported that since November 2020, Prime Minister Boris Johnson has been sent a summary of his ‘red box’, containing prime ministerial business to attend to, via WhatsApp. These reports of high-profile usage have been followed by the emergence of a Cabinet Office policy that arguably encourages the use of self-deleting instant messaging, and research from the Institute for Government that shows divergent policies on this issue across government.

What should we make of these quickly evolving practices? Instant messaging technologies such as WhatsApp undoubtedly have their benefits for public officials, and the effective functioning of government overall. Perhaps most notably, they can enable officials to exchange messages and share information more easily than other systems. However, they create a range of complexities as regards the preservation of the public record, particularly where these technologies are used in place of documented meetings or official email communications. Not least amongst these complexities is that the use of these technologies engages a variety of public law norms related to governmental record-keeping and the disclosure of information. As practices have emerged, it has become increasingly clear that the use of WhatsApp by the UK government may be at risk of being in violation of these public law norms.

The Constitutional Reform Act 2005 led to greater judicial independence: politicians and parliament must continue to support it

As part of an ongoing inquiry, the Lords Constitution Committee has sought evidence as to whether ‘the amendment of the role of the Lord Chancellor by the Constitutional Reform Act 2005 (CRA), and the resulting separation of powers between the judiciary and the Government, [have] been successful’. Robert Hazell argues that the 2005 reforms led to greater judicial independence, a political achievement that requires continuing support from politicians and parliament.

The House of Lords Constitution Committee is currently undertaking an inquiry into the role of the Lord Chancellor and the Law Officers, in which it seeks to answer a number of questions, including whether ‘the amendment of the role of the Lord Chancellor by the Constitutional Reform Act 2005 (CRA), and the resulting separation of powers between the judiciary and the Government, [have] been successful’. Through written evidence, submitted with Professor Kate Malleson, I have attempted to answer that question. Our answers were based upon the main findings and conclusions of a three-year research project on the Politics of Judicial Independence, funded by the AHRC. The research explored the impact of the greater separation of powers introduced by the Constitutional Reform Act 2005 (CRA). Our principal conclusion – as explained in our 2015 book on the subject – was that judicial independence and judicial accountability have emerged stronger, not weaker; but that greater separation of powers requires increased engagement by the judiciary with other branches of government.

The changes made by the Constitutional Reform Act 2005

Until 2005 the head of the judiciary was a Cabinet minister, the Lord Chancellor. In an extraordinary breach of separation of powers, he could also sit as a judge in the UK’s highest court. The CRA removed the Lord Chancellor as head of the judiciary, handing that responsibility to the Lord Chief Justice in line with an agreement struck in the Concordat of 2004. The division of powers between the executive and judiciary was further refined in 2008 in a Framework Document for the management of the Courts Service (revised and updated in 2011 to incorporate the Tribunals Service). The CRA also created a new Supreme Court, and established the Judicial Appointments Commission.

The new politics of judicial independence are more formal, fragmented, and politicised

The old politics were informal, depending on regular meetings between the Lord Chancellor and senior judges; closed, in that these were virtually the only contacts between the judiciary and the government; and secretive, with both sides preserving each other’s confidences. They were also consensual and conservative, in that neither side wanted to change the system. The ‘new’ politics, by contrast, are much more formal. The CRA required more formal structures and processes to handle the relationships between more separate branches of government. We now have the Judicial Appointments Commission, Judicial Appointments and Conduct Ombudsman, and Judicial Conduct Investigations Office: all products of the CRA. The new formal processes include regular meetings between the judiciary and other branches of government, with the innovation of six-monthly meetings between the LCJ and Prime Minister, the introduction of regular meetings with senior officials in parliament, and annual appearances by the LCJ and President of the Supreme Court before the Constitution Committee.
