The authority of the classic Diceyan approach to parliamentary sovereignty has, as is well known, been called into question as a result of the UK's membership of the EU and human rights legislation. However, this paper focuses on the implications of Scottish devolution for the orthodox doctrine of parliamentary sovereignty. The constitution, and the legislative supremacy of Westminster within it, remains a controversial political issue in Scotland. Accordingly, rather than hypothesising inductively from constitutional doctrine, consideration is given to the nature of the interaction between the socio-political forces which underlie Scottish devolution and the concept of parliamentary sovereignty. It is contended that the foundations of the Scottish political order have shifted in a way which is already presenting significant challenges. Moreover, looking to the future, the pressure on the orthodox Diceyan approach is likely to intensify over time. In this context, it is questionable whether constitutional conventions of the sort which are already evolving or the possible development by the courts of more formal constitutional norms will, in the long term, be able to reconcile parliamentary sovereignty with Scottish political reality. Indeed, it is argued that — from a Scottish perspective at least — the viability of classic, Diceyan parliamentary sovereignty as a meaningful constitutional doctrine will be called into question in the years to come.

For discussion of the doctrine of implied repeal, see the leading case on the matter, Ellen Street Estates v Minister of Health [1934] 1 KB 590 at 597, per Maugham LJ; and Elliott, above n 16. The two Acts of Parliament in question in Factortame did not, on the face of it, concern the same subject matter: the European Communities Act 1972 concerned the UK's legal relationship with the EC, and the Merchant Shipping Act 1988 was obviously concerned with shipping. Accordingly, in this narrow sense, the Merchant Shipping Act did not seek implicitly to repeal the European Communities Act.

43. For a contrary view of the status of Acts of the Scottish Parliament, see N Burrows Devolution (London: Sweet & Maxwell, 2000) pp 55–56. Burrows seeks to argue that the UK Parliament has conferred the power to legislate to the Scottish Parliament, thereby sharing the authority to pass primary legislation between Westminster and the Scottish Parliament. For a critique of Burrows' position, see Baer, S Umpiring the Ping-Pong game: the Courts and Legislative Conflict between Edinburgh and Westminster’ (2002) 1 Google Scholar JR 49 at 54–55.
44. The Human Rights Act also seeks to preserve the formal integrity of parliamentary sovereignty. Whilst incorporating the European Convention on Human Rights into UK domestic law, the Act defers to the principle of parliamentary sovereignty by not permitting the courts to declare Acts of Parliament which are incompatible with Convention rights to be without the force of law: instead, it merely empowers the courts to make a declaration of incompatibility. The responsibility for deciding whether or not to address the incompatibility through legislation is therefore left to Parliament, leaving open the possibility, in formal terms at least, that it may exercise sovereignty by choosing not to comply with Convention rights. However, in reality, the Human Rights Act constitutes a very significant transfer of sovereignty from Parliament to the judiciary. For discussion of these issues, see K D Ewing ‘The Human Rights Act and Parliamentary Democracy’ (1999) 62 MLR 79; and D W Vick ‘Deontological Dicta’ (2002) 65 MLR 279.

49. The Judicial Committee's functions are provided for under s 33 and Sch 6 to the Scotland Act; and its status as the final court of appeal under the devolution settlement is determined by s 103. It is, however, very much a court of last resort, with the Scottish supreme courts (ie the Court of Session and the High Court of Justiciary) dealing with most devolution issues.

52. Whaley v Lord Watson 2000 SC 340 at 357E–358A, per Lord Prosser. The interrelationship between the Scottish Parliament and the courts was considered further in Adams v Scottish Ministers 2003 SC 171. Thus, the Scotland Act is definitive in terms of determining the extent of the court's jurisdiction to review the actions of the Scottish Parliament, which possesses a discretionary area of judgement to which the courts should defer (other than where the Parliament contravenes the ECHR).
53. And, to some extent, national chauvinism. This approach finds its full expression in Dicey's writings. Keeton argued that Dicey ‘inherited an outlook upon the constitution which owed something to Burke, Blackstone and Bagehot, and which saw in the English system the climax of political achievement’: see G W Keeton The Passing of Parliament (London: Graff, 1952) p 6, as reproduced in Loughlin, above n 6, p 141. Dicey was strongly opposed to Irish Home Rule, and it is reasonable to suppose that he would have also have opposed the Scottish devolution settlement: see Lord Bingham of Cornhill ‘Dicey Revisited’ [2002] PL 44.

61. Accordingly, David McCrone has written that the failure of the political class to deliver devolution in 1979 - remember that a majority of Scots voted yes, but the measure was defeated by a parliamentary gerrymander known as the 40% rule - coupled with the re-election of a Conservative government at Westminster in 1992 with a mere quarter of the popular vote in Scotland, and 11 out of 72 seats, persuaded many in civil society that things could not be left to political parties. To be sure, politicians were included in the various deliberations and commissions over 20 years, but they were usually invited to do so because they had special interests in or sympathies for Home Rule. In short, Scotland's parliament was to be a creation of civil society, and hence a doctrine of parliamentary sovereignty was inappropriate.

86. There are some concerns that the current Scottish Executive is making extensive use of the Sewel convention. This is perhaps inevitable given the shared objectives of the Labour government at UK level and the Labour-dominated Scottish Executive. The ebb and flow of party politics north and south of the border would, however, suggest that this is likely to be a relatively short-term situation. Furthermore, the use of the Sewel convention can be advantageous to both Edinburgh and Westminster, in that it enables a UK-wide approach to be taken in appropriate or non-controversial areas, avoids the risk of judicial challenge, and provides extra time in the Scottish Parliament.

92. This possibility was a topic of heated (but not particularly illuminating) debate during the 2003 election campaign, when London-based Labour Party sources appeared to suggest that Westminster sovereignty would be exercised to prevent an SNP-dominated Scottish Parliament from legislating for a referendum on independence. Previously, Scottish-based Labour politicians and law officers had seemed to concede that, although legislating in order to effect constitutional change was reserved to Westminster under Sch 5 to the Scotland Act, the Scottish Parliament was able to legislate for a referendum on any topic, and that in political terms a majority vote for independence in a referendum could not be challenged. This latter view ultimately appeared to prevail in the closing stages of the 2003 campaign.
