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.

Monitor 82: achieving a new normal for the constitution?

Today the Unit published Monitor 82, containing reporting and analysis of recent constitutional events, covering the period from 1 August to the debates on the Counsellors of State Bill earlier this week. Even by the standard of recent years, the last four months has been a period of constitutional turbulence that has seen the ousting of two Prime Ministers and the death of a monarch who had sometimes seemed a constitutional constant. Meg Russell and Alan Renwick argue, in this piece, which is also the lead article for Monitor, that the new Prime Minister and monarch face significant challenges if they wish to rebuild stability and faith in the UK’s institutions.

Recent months have seen unprecedented turbulence in UK politics. This blogpost, like the current issue of Monitor, covers developments over just four months, yet reports on a change of monarch and two changes of Prime Minister, plus remarkable churn in ministerial positions, and much else.

As reported in the previous issue of Monitor, in early July Prime Minister Boris Johnson was forced to announce his departure following a wave of ministerial resignations. Concerns about propriety and integrity were central to his removal. Yet these topics played disappointingly little part in the leadership contest which unfolded over the summer, including in a series of hustings meetings for Conservative Party members between Rishi Sunak and Liz Truss. The primary focus of the contest was understandably the cost of living, with contention between the candidates over their economic approaches – Sunak warned against the dangers of Truss’s proposed unfunded tax cuts.

Truss won the contest, becoming Conservative Party leader on Monday 5 September, and she was appointed Prime Minister the following day by Queen Elizabeth. Cabinet positions began to be filled the day after that. But on 8 September, the day of the new government’s first major statement on the energy crisis, news emerged that the Queen was unwell. Her death was announced that evening. The end of a reign lasting over 70 years was a major moment for the United Kingdom’s national and constitutional self-understanding. The country entered a period of national mourning during which the funeral was held. Prince Charles immediately became King. Within days, he delivered a televised address, gave an oath at the Accession Council, addressed MPs and peers in Westminster Hall, and spoke at the Scottish Parliament, the Senedd, and Hillsborough Castle.

This delayed the new government’s activities, but a shock of a different kind occurred on 23 September, when Chancellor of the Exchequer Kwasi Kwarteng announced his so-called ‘mini budget’ to the House of Commons. Including ambitious tax cuts beyond those that Truss had pledged during the campaign, it resulted in grave instability for the financial markets. Ultimately Truss sacked Kwarteng on 14 October, but was forced to announce her own resignation just six days later. This triggered a further Conservative leadership contest, which saw Sunak appointed to the role of party leader and Prime Minister.

The problem(s) of House of Lords appointments

Lords appointments are back in the news, with rumours of resignation honours from Boris Johnson, and even possibly Liz Truss. The current unregulated system of prime ministerial patronage causes multiple problems, and new Constitution Unit polling shows widespread public demand for change. Meg Russell reviews the problems and possible solutions, in the context of a bill on Lords appointments due for debate tomorrow. She argues that small-scale changes are now urgently required, and urges party leaders to embrace them – whatever their longer-term aspirations for Lords reform.

Recent weeks have seen revived controversies about appointments to the House of Lords. These include concerns about Boris Johnson’s long-rumoured resignation honours list, now joined by concerns that Liz Truss may want resignation honours of her own after just 49 days as Prime Minister. While the personalities may be different, controversies over Lords appointments are nothing new. The central overarching problem is the unregulated patronage power that rests with the Prime Minister. As this post highlights, a series of other problems follow: regarding the chamber’s size, its party balance, the quality of candidates appointed, the chamber’s reputation and widespread public dissatisfaction with the system.

An end to the Prime Minister’s unfettered appointment power is long overdue. Tomorrow a bill will be debated in the Lords aiming to tackle some of the problems, but as a backbench bill it is unlikely to succeed. Its contents nonetheless provide a useful (though incomplete) guide to the kind of important small-scale changes needed. Both main party leaders now need urgently to propose short-term packages of their own.

The problem of the size of the Lords

Much attention has focused in recent years on the spiralling size of the House of Lords. The current system places no limits whatsoever on the number of members who may be appointed to the chamber by the Prime Minister. Most – though not all – prime ministers have appointed unsustainably. Particularly given that peerages are for life, over-appointment drives the size of the chamber ever upwards. This is a historic problem, visible throughout the 20th century. The Blair government’s reform of 1999 brought the size of the chamber down (from around 1200 to just over 650). But since then it has risen again. Two reports from the Constitution Unit – in 2011 and 2015 – analysed this problem, calling for urgent action. In 2016 the Lord Speaker established a cross-party Committee on the Size of the House, which made recommendations the following year. Centrally these included restraint by the Prime Minister based on a ‘two-out-one-in’ principle – so that only one new peer would be appointed for every two who left, until the chamber stabilised at 600 members. These principles were endorsed by the Commons Public Administration and Constitutional Affairs Committee, and respected by Theresa May. But Boris Johnson ignored them. In 2021, the Lord Speaker’s Committee lamented how he had ‘undone progress’ achieved by his predecessor.

Protecting constitutional principles: what are they and why do they matter?

Recent debates about the health of the UK political system have raised questions about the core principles underlying constitutional democracy. Meg Russell, Alan Renwick and Lisa James set out some of these principles, and argue that MPs have a particular responsibility for upholding them.

Recent years have seen much discussion of the health of UK democracy, and some concerns about the risk of ‘democratic backsliding’. But this raises the question ‘backsliding from what’?

Widely shared assumptions exist about the principles which underlie constitutional (or ‘liberal’) democracies – the features that distinguish them from autocracies and so-called ‘illiberal democracies’. Although the UK famously lacks a codified constitution, such values are deeply embedded in its constitutional traditions and arrangements.

This briefing identifies and explains five such core principles:

  1. Institutional checks and balances
  2. Representative government, and free and fair elections
  3. Rule of law
  4. Fundamental rights
  5. Integrity and standards

The UK’s constitutional norms and standards took a severe battering under Johnson: Labour should pledge to restore the system

There is no guarantee that the Johnson government’s dismal record on safeguarding our democracy will be improved upon by the new Prime Minister, Liz Truss. This creates big opportunities for Labour to offer a real alternative by restoring integrity and accountability to politics, writes Meg Russell.

Concerns about honesty and integrity and the erosion of constitutional norms were central to Boris Johnson’s dramatic downfall. The new Prime Minister’s attitudes in this area remain largely untested – though the omens during this summer’s leadership contest were not good. Meanwhile, public opinion research suggests that voters really care about these questions. That presents significant opportunities for Labour.

The charge sheet against Johnson was remarkably long. The journalist Peter Oborne, formerly political editor of the Spectator and a Telegraph columnist, dedicated both a website and a book to chronicling Johnson’s uneasy relationship with the truth. This trait was well known before he assumed the premiership and to an extent ‘priced in’. But the difficulties under his leadership went far wider, covering multiple aspects of integrity in politics and respect for the essential rules and norms that underpin UK democracy. This often put him at odds with regulators and non-political figures holding responsibility for maintaining the system, as well as with senior figures in his own party.
