Chapter 9: Parliamentary Sovereignty Flashcards
1 Historical background and theory
1.1 Historical background
As we have previously seen, the so-called ‘Glorious Revolution’ of 1688 marked the most significant long-term turning point in English constitutional history. Though events had been more dramatic and violent in the 1640s and 1650s, the coup against James II and his replacement by William III marked the final end of absolutist monarchy in the
country.
This was reflected in key provisions of the Bill of Rights 1689 and later in the Act of Settlement 1701. These founding pieces of legislation effectively enshrined the sovereignty of Parliament as an institution.
No monarchs thereafter were able to ‘dispense with’ laws which that they did not like, or to dismiss judges at will, as the Stuarts claimed to be able to. Statute, made by Parliament,
became the highest form of law.
1.2 Evolution of Parliamentary authority
Monarchs continued to have considerable political power and influence into the 19th century and
the country remained an oligarchy for a considerable period. There were three electoral Reform Acts in the 19th century, during which time the franchise expanded gradually, but it was not until 1928 that all men and women (over 21) could vote on an equal basis.
Though the doctrine of parliamentary sovereignty is usually associated with Professor Dicey’s
writings in the 1880s, it was not until the 20th century that one could say that the principle was directly linked to the ideal of a full democracy.
1.3 Dicey’s theory
The principle of Parliamentary Sovereignty means nothing more or less than this, namely Parliament thus defined has, under the English Constitution, the right to make or unmake any law whatsoever; and, further, that no person or body is recognised by the law of England as
having a right to override or set aside the legislation of Parliament.
Three key elements to Dicey’s theory
- Parliament is the supreme law-making body.
- No Parliament may be bound by a predecessor or may bind a successor.
- No person or body may question the validity of an enactment of Parliament.
1.4 Supreme law-making body (no legal but political limits)
Dicey means here that there are no substantive limitations on the legislation that Parliament may
enact. (Note that he is referring to the absence of any legal limitations on Parliament – he acknowledged that there are clearly political limits on what it can do.)
1.4.1 No substantive restrictions on Parliament
Parliament can also legislate, if it wishes, contrary to fundamental rights (though note the effect of the HRA since 2000). In your separate materials on the rule of law, we saw this point made by Lord Hoffmann in 2000 in the ex parte Simms case when he set out his so-called ‘legality
principle’.
Contrary to international law & Retrospective Effect
Parliament can also legislate contrary to international law – there are instances, such as in the cases of Mortensen v Peters and Cheney v Conn where the UK courts have clearly enforced the UK statute rather than international law. Additionally, Parliament can pass legislation that has retrospective effect, even though this is not
seen as desirable in rule of law terms. Examples include the War Damages Act 1965 and the War
Crimes Act 1991.
1.5 No entrenchment
When Dicey said that no Parliament may be bound by a predecessor or bind a successor, he was referring to the absence of entrenchment as a constitutional safeguard in the UK constitution.
As we saw at the start of the course, the UK’s uncodified constitution does not possess any formal arrangements to entrench its constitutional fundamentals. This is unlike the vast majority of other democratic states, which tend to have mechanisms (of varying strength) which are designed
to make it harder to change constitutional basics and law than it is to change ordinary law.
In the UK the constitution can potentially be drastically changed by a single Act of Parliament. This could happen through new law or repeal of existing law. In the UK repeal can take an express or implied form.
1.5.1 Express repeal
Express repeal occurs when legislation is passed that expressly states an intention that an earlier
Act should be replaced. For example, the Interception of Communications Act 1985 was expressly repealed and replaced by the Regulation of Investigatory Powers Act 2000.
Express repeal often happens when there is a drive to consolidate and simplify legislation. For example, the Sex Discrimination Act 1975, the Race Relations Act 1976, and the Disability Discrimination Act 1995 were all expressly repealed and replaced by the Equality Act 2010.
1.5.2 Implied repeal
Implied repeal operates on a more subtle level and is a key feature of the second element of Dicey’s theory on sovereignty. This comes about (in the absence of express repeal) if a new Act is partially or wholly inconsistent with a previous Act.
If so, the previous Act is repealed to the extent of the inconsistency.
This is known as implied repeal because Parliament is deemed to have implicitly intended the later
Act to repeal the earlier one in this situation.
This implicit intention arises from a presumption that Parliament would not intend two incompatible statutes to be given effect at the same time - it would intend to give effect to the later statute, as this is the most recent expression of its will.
The courts will only draw the implication that Parliament intended to repeal an earlier statute where two statutes are irreconcilable.
1.5.3 Effect of implied repeal
The significance of implied repeal for parliamentary sovereignty is that Parliament cannot bind its successors so as to prevent a statute from being impliedly repealed by a later one which is incompatible with it.
Implied repeal is a reflection of the traditional view that sovereignty takes a ‘continuing’ form, and that each new Parliament (with a fresh mandate) should have equal freedom of manoeuvre in
creating new legislation.
Vauxhall Estates v Liverpool Corporation [1932] 1 KB 133
and Ellen St Estates v Minister of Health [1934] 1 KB 590,
The theory was borne out in the cases of Vauxhall Estates v Liverpool Corporation [1932] 1 KB 133 and Ellen St Estates v Minister of Health [1934] 1 KB 590, which both involved compensation for landowners whose property had been compulsorily purchased under legislation passed after the First World War.
Housing Act 1925.
In both cases, the defendants were told that their compensation was to be assessed according to the terms of the Housing Act 1925. They argued, however, that the assessment should be calculated according to the (more generous terms) of the Acquisition of Land Act 1919. The 1919 Act had expressly stipulated that its provisions were to prevail over any other statutes (thereby trying to prevent future implied repeal).
Parliament is not able to bind its successors
The courts denied that the 1919 Act was intended to have that effect but, significantly, they added
that, even if this had been the intention, the 1919 Act still could not have prevented the 1925 Act
from impliedly repealing it, as Parliament is not able to bind its successors. The terms of the later
1925 Act were therefore applied.
Note a more modern and very significant proviso to this part of the theory, as set out by Laws LJ
in the case of Thoburn v Sunderland City Council [2002] EWHC 195 (Admin).
1.6 Validity of Acts of Parliament
The third limb of Dicey’s theory follows naturally from the basic doctrine that law created by
Parliament is supreme. It rests on the notion that Acts of Parliament are the highest form of law, so neither the manner in which legislation is passed, nor the substance of the law, should be
reviewable by the courts.
Procedural Inequality: UK courts are not able to quash or invalidate primary legislation
Unlike the situation in many other democratic states, therefore, the UK courts are not able to quash or invalidate primary legislation, even if this legislation might be deemed ‘unconstitutional’ or contrary to international law standards. This also means that Diceyan theory does not allow for judicial review of any alleged procedural irregularity in the way that statute had gone through Parliament during the legislative process.
1.6.1 Enrolled Bill rule
This ‘rule’, applied historically by the courts, effectively means that if a bill has been enrolled - ie it has become an Act of Parliament - it is impossible to go behind that. Any departure from normal procedure during the passage of the bill cannot be corrected by the courts.
This approach was evident in two significant cases: Edinburgh and Dalkeith Railway v Wauchope
(1842) 8 ER 279 (HL) and Pickin v British Railways Board [1974] AC 765
Lord Morris Judgement
When an enactment is passed there is finality unless and until it is amended or repealed by Parliament. In the courts there may be argument as to the correct interpretation of the
enactment: there must be none as to whether it should be on the Statute Book at all.
1.7 Parliamentary sovereignty and the character of the constitution
The Diceyan conception of parliamentary sovereignty can therefore be seen as a primary element in forging the traditional character of the UK constitution.
The supreme authority of statute law and the apparent impossibility of entrenchment of constitutional basics means that the UK has a potentially highly flexible constitution. It also enhances the broadly political character of the UK constitution in which political ‘drivers’ of change tend to be more significant than fundamental constitutional rules.
1.8 Summary
Professor A. V. Dicey’s works, including the Study of the Law of the Constitution, set out the theory of parliamentary sovereignty in the UK.
- The key components of Dicey’s theory include:
- Parliament as the supreme law-making authority
- The inability of Parliament to bind itself
- The associated concept of implied repeal
- The inability of any other body or person to question an Act of Parliament
- Contemporary law and politics highlight the limitations of Dicey’s theory.
- Limitations on parliamentary sovereignty
Context
The essence of Professor A.V. Dicey’s theory, which has been a mainstay of UK constitutional law since the late 19th century, is that the Westminster Parliament has unlimited legal powers.
No substantive or procedural limitations can in theory therefore apply to its legislative powers.
In the intervening years, however, a number of legal and constitutional developments have taken place and a number of challenges have been brought to the courts which have arguably diluted the purity of Diceyan doctrine.
Note that this subject area is controversial and remains politically highly contentious – concerns
about sovereignty have formed the theoretical backdrop to many significant political trends,
including the UK’s recent separation from the EU.
2.2 Procedural limitations
One of the issues that has arisen has been whether it is possible for Parliament to introduce procedural requirements to make it harder for subsequent parliaments to change the law, for instance by requiring prior popular approval for repeal in a referendum.
Entrenchment by ‘manner and form’.
This idea is what is known as entrenchment by ‘manner and form’.
The orthodox Diceyan view is that, while a parliament could pass a statute that required a special
procedure for its amendment or repeal, this requirement would not be binding on a successor parliament.Additionally, the courts would not consider a challenge to the subsequent incompatible statute
because of the ‘enrolled bill rule’ laid down in Pickin v British Railways Board [1974] UKHL 1.
2.2.1 Commonwealth cases
There has been academic argument over this issue, however, inspired initially by the Privy Council
case of Attorney General for New South Wales v Trethowan [1932] AC 526. This concerned the legislature of New South Wales, Australia, which had originally been created
by the UK Parliament in 1823.
In 1929, legislation was passed in New South Wales which prohibited the abolition of the upper chamber of the legislature without referendum approval. The following year, the legislature passed two Bills designed to abolish the upper chamber without holding the required referendum.
The Privy Council granted injunctions preventing royal assent from being granted to the Bills because they had not been passed in the correct manner.
Not a sovereign legislation
Critics of the manner and form argument have pointed out that the New South Wales legislature was a creation of the UK Parliament and was subordinate to it. It was not a sovereign legislature and so its legal position was quite different from that of the UK Parliament itself.
The possibility of manner and form entrenchment only therefore seems to apply – according to this reasoning – to subordinate legislatures, such as the devolved assemblies in the UK.
Referendum lock
Arguments have persisted, however, and the issue came to the fore again with the European Union Act 2011, which introduced a ‘referendum lock‘. This was a statutory framework requiring a referendum to be held before further amendments could be made to the founding Treaties of the
EU. The referendum lock provision in the Act seemed to extend this pledge beyond the life of that Parliament by creating a manner and form requirement.
Status of the Lock
(Note, however, that the status of the lock was never tested in the courts before the UK left the EU.)
The debate over the possibility of procedural limitations on Parliament’s powers has continued in some significant obiter discussion in the higher courts.
In Thoburn v Sunderland City Council [2002] EWHC 195 (Admin), Laws LJ asserted that ‘Parliament […] cannot stipulate as to the manner and form of any subsequent legislation’.
Jackson v AttorneyGeneral [2005] UKHL 56. Lady Hale stated
If the sovereign Parliament can redefine itself downwards, to remove or modify the requirement
for the consent of the Upper House, [ie via the Parliament Acts] it may very well be that it can also redefine itself upwards, to require a particular parliamentary majority or a popular
referendum for particular types of measure. In each case, the courts would be respecting the will of the sovereign Parliament as constituted when that will had been expressed.
2.3 Legislative independence
One of the most notable historical challenges to the notion of Westminster omnipotence has been
the ending of Empire and partial erosion of the Union (of the UK).
There has always been a different conception of the powers of Westminster in Scotland to that
held in England and Wales. See for example the approach taken by the Scottish judiciary in cases such as MacCormick v Lord Advocate [1953] SC 396.
Acts of Union
The theory behind this was that the Acts of Union were not created by the UK Parliament but by the original English, Scottish and Irish Parliaments. Hence, the Acts created a new UK Parliament that did not have unlimited sovereignty but was limited by its founding constitutional documents. In the words of Professor J. Mitchell, the new Parliament was ‘born unfree‘.
2.3.1 The ‘Dominions’
Starting with Canada (in 1867) and subsequently (in 1901 and 1907 respectively) with Australia
and New Zealand, Dominion status was given to recognise a number of semi-independent states under the British Empire.
The Dominions’ constitutions were established by UK Acts of Parliament. A constitutional convention developed that no new UK Act affecting a Dominion would be passed without the request and consent of that Dominion - in recognition of their autonomous status.
This was confirmed in s 4 of the Statute of Westminster 1931, which required there to be a recital
in the relevant legislation of the request and consent from the Dominion.
2.3.2 Impact on Westminster sovereignty
The political reality of the autonomy (and subsequent complete independence) granted to the
Dominion nations subsequently caused significant conceptual challenges to the original Diceyan
doctrine of parliamentary sovereignty
Reducing own sphere of political authority
In granting Dominion status to the three original countries (and subsequently six others) the
Westminster Parliament had effectively legislated to reduce its own sphere of political authority.
In UK terms the most significant development was the granting of Dominion status to the new Irish
Free State in 1922 (subsequently the Republic of Ireland from 1949), comprising all the island of
Ireland except the six north-eastern counties of Northern Ireland.
2.3.3 Legal authority of Westminster?
The problem for the courts since these developments has been reconciling the undoubted political
diminution of Westminster authority with the orthodox legal principle in Dicey’s theory.
Some judges have been at great pains to state that political change has not diminished the unlimited legal authority of Parliament – see, for example, Megarry VC in Manuel v Attorney General [1983] Ch 77.
Others have emphasised that political and legal authority operate on entirely different planes, as
Lord Denning put it in Blackburn v Attorney General [1971] 1 WLR 1307, a case concerning UK membership of the (then) European Economic Community
Statute of Westminster 1931
We have all been brought up to believe that, in legal theory, one parliament cannot bind
another and that no act is irreversible. But legal theory does not always march alongside
political reality. Take the Statute of Westminster 1931 […]. Can anyone imagine that Parliament could or would reverse that statute? Take the Acts which have granted independence to the Dominions […]. Can anyone imagine that parliament could or would reverse those laws and take away their independence? Most clearly not. Freedom once given cannot be taken away.
Legal theory must give way to practical politics.
2.4 Impact of devolution
Program of Devolution
We have seen at the start of the course how the programme of devolution, which has been
underway since 1998, has shaped the constitution of the UK, as well as how it has been implemented.
One cannot directly compare the degree of autonomy given to Scotland, Wales and Northern
Ireland to the more significant semi-independence given to the Dominion countries in the late 19th/early 20th centuries.
Direct rule‘ from Westminster
In the past, autonomous powers given by Westminster have been suspended or taken away. For
instance, ‘Direct rule‘ from Westminster was imposed on Northern Ireland from 1972 to 1998, after the province had been run by its own ‘Government’ in Stormont from 1921. Significant layers of local government have also been abolished – notably the Thatcher
government’s abolition of the GLC (Greater London Council) in 1986.
Enhanced devolution
Nevertheless, an argument can be made that, in the absence of more dramatic political events (as
occurred in Northern Ireland), the political acceptance of devolution in Scotland and Wales means that it is very difficult to see how the original devolution would be reversed. This is even more the case given the political direction of travel of the policy - ie towards enhanced devolution, and in Scotland’s case the possibility of a further independence referendum.
Political limitation
This is, of course, a political limitation on the authority of the Westminster Parliament rather than a legal one – Parliament could still ‘unmake’ this law and any other in Diceyan theory – but in practical terms it arguably takes the orthodox theory into abstract territory.
2.5 Summary
The sovereignty of the Westminster Parliament can arguably be limited by:
- Parliament divesting itself politically of areas once under its own authority
- Devolved legislation
- ‘Practical politics’ (per Lord Denning in Blackburn v AG)
3 Impact of EU membership
3.1 Context
The orthodox Diceyan theory on parliamentary sovereignty is based on the idea that the legal
authority of the Westminster Parliament is unlimited.
It is also apparent, however, that over time Westminster has given away political authority to
newly independent nations and arguably diluted it in respect of the devolution arrangements
within the UK.
It’s also crucial to assess how the 47-year experience of the UK’s membership of the European
Union (EU) and its predecessor bodies has impacted on the doctrine of parliamentary supremacy.
Though this membership is now at an end, it will also continue to have a significant future bearing
on constitutional law in the UK.
3.2 UK as a ‘dualist’ state
Unlike ‘monist’ states, in which domestic and international law obligations operate on the same
plane, the UK is a dualist state, in which there is a distinction between the two sources of law.
As seen in cases such as Mortensen v Peters, domestic law has a higher status in the UK legal system, because this is created by the sovereign Parliament. If Parliament therefore wishes international legal systems or sets of standards to be enforced, it needs firstly to ‘incorporate‘ this body of external law into the UK legal system by passing a statute to that effect.
This is what was done in 1972 with the passing of the European Communities Act (ECA). As we will
see later, a similar process occurred in 1998 with the passing of the Human Rights Act, which
incorporated the European Convention on Human Rights.
3.3 EC/EU Treaty obligations
The UK signed the Treaty of Accession in 1972 and became a full member of the European
Communities (now known as the European Union) from 1 January 1973. In order to incorporate the Treaty of Rome 1957 into domestic law, Parliament passed the ECA
1972.
Since then, a number of other treaties have modified or amended the original Treaty. This includes
the Maastricht Treaty which first established the European Union. These have also been incorporated into UK law by statute amending the ECA.
For the sake of clarity, the body of law created by both the European Communities and the
European Union will simply be referred to as ‘EU law’.
