Chapter 6: Separation of Powers Flashcards
1.1 Theory of the separation of powers
It is widely acknowledged that the concentration of all types of state power into the same hands
can lead to iniquitous and/or inefficient government. In the famous words of the British historian, Lord Acton: ‘Power tends to corrupt; absolute power corrupts absolutely.’
Constitutional Theorist Argument
Constitutional theorists argue that, for a constitution to be ‘efficient’ and ‘well arranged’, the three branches (or organs) of state – the judiciary, executive and legislature –should be
separated into different bodies or persons.
Aristotle Theory
This theory has deep roots in ancient political theory. While not employing the same terms as modern thinkers, Aristotle stated in The Politics (384-322 BC): There are three elements in each constitution in respect of which every serious lawgiver must look for what is advantageous to it; if these are well arranged, the constitution is bound to be well arranged […] The three are, first, the deliberative, which discusses everything of common importance; second, the officials; and third, the judicial element.
1.1.1 Montesquieu
This theory was given more modern expression by the 18th century, French philosopher, Montesquieu. He believed that liberty would be best protected in a state if there was a separation of powers into judicial, executive and legislative branches. He expressed it in this way in De L’Esprit des lois
Legislative and Executive powers are united
When the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty […] again, there is no liberty if the power of judging is not separated from the legislative and the executive. If it were joined with the
legislative, the life and liberty of the subject would be exposed to arbitrary control; for the judge would then be the legislator. If it were joined to the executive power, the judge might behave with violence and oppression
No society, no separation, no constitution
There would be an end to everything, if the same man,
or the same body, whether of the nobles, or of the people, were to exercise those three powers,
that of enacting laws, that of executing public affairs and that of trying crimes or individual causes. Any society in which the safeguarding of rights is not assured, and the separation of powers is not observed, has no constitution.
1.2 Separation of powers in practice
It should be stressed above all that the separation of powers is a theory or an ideal. Practice varies greatly between different states and different political cultures tend to have differing perspectives on the degree to which the theory can and should be implemented. The country most closely associated with the ideal is the United States where the constitution was directly inspired by the principles associated with Enlightenment thinkers such as Montesquieu, Rousseau and Locke
Complete Separation of Power & Confidence in Legislature
The key difference is the complete separation in the US between Executive and Legislature. The US
constitution does not allow simultaneous membership of the government and of Congress,
thereby establishing a very notable form of ‘check and balance’ between the two political wings of the state. Like the US, the French constitution also provides for a directly elected President as head of state. However, most modern democratic nations have a form of government which depends on the support and confidence of the legislature, selected through general elections, as in the UK.
1.3 Context of separation of powers in the UK: Attachment to the principle of parliamentary sovereignty
As we will see in this topic, the degree to which the UK conforms to any model of separation of
powers is a controversial question.
This is a product of the organic development of the UK’s constitution, which has never been the subject of planned design, and of the UK’s continued attachment to the principle of parliamentary sovereignty.
Lack of clear-cut rules and delineations
The lack of clear-cut rules and delineations between the responsibilities of the three bodies of
state has meant that an accommodation has to be reached between them in order to establish a
balance that can be seen as constitutionally appropriate and healthy.
Seen as a co-equal
However, unlike the position in the USA, where each body of state is seen as ‘co-equal’, the UK’s
attachment to parliamentary sovereignty means that there is not an equal balance of power in
the first place. As we have seen, UK courts do not have the power to invalidate or ‘quash’ primary legislation if this is deemed unconstitutional. Unlike the situation in the US and many other modern
democracies, the UK’s Supreme Court is not a constitutional court in this sense of being able to
review primary legislation for compliance with constitutional fundamentals.
1.3.1 Consequences
The unique context of the UK’s constitutional development has meant that there are a number of
issues and discussion points that are engaged when one considers how the separation of powers manifests itself.
Institutional overlaps
* The lack of design to the UK constitution has meant that there have historically been
significant functional overlaps between all three bodies.
* How far does this ‘fusion’ still impact on the efficiency of and balance to the constitution?
The judicial role? Two main issues impact on the judiciary in particular:
* What power does the judiciary have to scrutinise and control the actions of the executive?
* To what extent, if at all, can the judiciary ‘make’ law?
1.4 Summary
The separation of powers is an ideal which seeks to prevent power in a society being overly concentrated in the hands of a few.
* As an ideal it can be traced back to classical times, but it was mainly developed in the Enlightenment period.
* The degree of attachment to the ideal varies considerably between different states.
* The idiosyncratic development of the UK constitution has meant that there are no clear lines of
separation between the executive and the legislature.
* The UK’s attachment to parliamentary sovereignty has meant that the three bodies of state in the UK are not ‘co-equal’ as in the US.
* The proper role and degree of power of the judiciary in the UK remains controversial, therefore
2 The Executive
Constitutional context
We have seen in relation to the theme of ‘responsible government’ how intra-parliamentary forms
of scrutiny can assist to a degree in holding the executive to account.
We now need to consider the broader institutional picture, in which the balance of power and
responsibilities between executive and legislature can be assessed.
In other materials we will also see the degree to which the courts are able to scrutinise the actions
of the executive and to hold government to account legally, which is where the constitutional
principles of the separation of powers and the rule of law intersect.
2.2 What is the executive?
Executive functions are incapable of comprehensive definition, for they are merely the residue
of functions of government after legislative and judicial functions have been taken away. They may, however, be said to entail the formulation or application of general policy in relation to particular situations or cases, or the making or execution of individual
discretionary decisions.
Executive Execution of Law & Policy
More specifically, they include the execution of law and policy, the maintenance of public order, the management of Crown property, the direction of foreign policy, the conduct of military operations, and the provision, regulation, financing or supervision of such services as
education, public health, transport and national insurance.
2.3 A fusion of powers?
Overlap
In the UK there has traditionally been a considerable degree of overlap in terms of personnel and
functions between the different branches of the state. Academic writers including Walter Bagehot (The English Constitution 1867) have identified this as being a result of the UK constitution being a parliamentary, as opposed to a presidential, system.
Parliamentary System
In a parliamentary system, the legislature selects and contains the political part of the executive
branch, which is then ultimately dependent on the legislature for its position and power. For this
reason, parliamentary systems are often seen to create a fusion of powers rather than a separation of powers.
Dangers of Fusion
In the UK, many commentators have warned of the potential dangers of such fusion, particularly given the traditionally strong degree of control exercised by the political parties over their MPs, through the whipping system, and the general tendency since 1945 for governing parties to enjoy large parliamentary majorities in a ‘first past the post’ electoral system.
2.4 Hung parliaments
The Conservative–Liberal Democrat coalition government of 2010–15 would be joined by up to
five years of a Tory minority government sustained in office by a ‘confidence and supply’
agreement with the Democratic Unionist Party (DUP) […] In between these supposedly
‘unusual’ peacetime conditions, there would be only a single year’s inter-regnum (2015–16)
when the Cameron government had a small but clear overall majority and operated on the
traditional pattern.
Westminster system
There was also a further year of Tory majority government under May
[before the 2017 general election], but it was marked by a good deal of post-Brexit Leaver– Remain conflicts that made her parliamentary situation very weak. […]
All of this might make the ‘Westminster system’ of disproportional elections producing ‘strong’ majority of governments’ and the associated ‘British political tradition’ look more suspect than ever before. One should note, however, that the start of the new decade has seen another reversion to the more familiar pattern, as the Johnson government holds an 80 plus majority after the December
2019 election.
2.5 Overlapping roles
Regardless of whether the government of the day has a functioning majority, it remains the case that political roles in government (ie at ministerial level) and in Parliament do overlap. The
relationship between the executive and the legislature can be described as a system of ‘checks and balances’ but whether the balance has fallen in the most favourable position is very much open to debate
2.6 Legislative functions of the executive
Primary Legislative Functions
One of the most significant functional overlaps is the executive’s ability to create secondary
legislation, as long as it has the authority to do so from primary legislation (in the shape of a
‘parent’ Act of Parliament).
Secondary Legislative Functions
Secondary – also called subordinate, or delegated – legislation takes the form of rules, orders and regulations, largely created as statutory instruments (SIs). There are approximately 3,500 SIs made annually, varying in length from a single page to several hundred pages.
