Matt Qvortrup, Leah Trueblood (2022)Schmitt, Dicey, and the power and limits of referendums in the United Kingdom, In: Legal studies (Society of Legal Scholars)42(3)0261387521000544pp. 396-407 Cambridge Univ Press

Carl Schmitt and AV Dicey are two of history's most influential constitutional theorists, and they offer two of history's most influential accounts of referendums. In most respects, their approaches to referendums are in direct opposition to each other. On Schmitt's view, the purpose of referendums is to acclaim executive actors. On Dicey's view, the role of referendums is to constrain them. Despite disagreeing about whether referendums should acclaim or constrain the executive, Schmitt and Dicey agree that an agenda-setting role for representatives in referendums is inevitable. This paper argues that, in the UK context, if Schmitt and Dicey are right about the necessary agenda-setting power of representatives in referendums, then the accounts of referendums they each offer must be two sides of the same coin. Given the dominance of the executive over the legislature in the UK and the uncodified nature of the constitution, referendums are processes that necessarily both acclaim and limit the executive.

Leah Trueblood (2025)Public Functions of Political Parties in the United Kingdom, In: Modern law review88(4)pp. 660-688 Wiley

Political parties are both private and public bodies. Some actions of political parties must be categorised as private to protect freedom of speech and association. This article argues, however, that it is sometimes necessary that political parties are understood as exercising public functions as well. When parties are exercising public functions, their actions then may be subject to judicial review. Currently, political parties have not been held to exercise public functions in the UK either for purposes of the Human Rights Act 1998 or common law judicial review. This article challenges the approach in UK law, particularly in Tortoise Media v Conservative Party [2023], which held that it was not even arguable that the selection of a Prime Minister by a political party was a public function. This article challenges this finding by offering a framework, drawn from current case law, for establishing when political parties are exercising public functions. The case law says that functions are public when bodies are 'operating as an integral part of a governmental framework'. These conditions were more than satisfied in Tortoise Media and offer a firm - albeit limited and context-contingent - basis for judicial review of actions by political parties.

Leah Trueblood (2025)Judicial review, ouster clauses, and the democratic credentials of the judiciary in the United Kingdom, In: Legal studies (Society of Legal Scholars)45(2)pp. 231-245 Cambridge Univ Press

The aim of this paper is to challenge the argument that says, as judges are not elected, they have weaker or no democratic legitimacy when compared to legislators. This paper draws on dicta from Laws LJ, as he then was, in the Divisional Court case of Cart v Upper Tribunal, to offer two reasons why this is false. Call these the efficacy and equality principles of representation. The claim here is that without an independent judiciary, legislators cannot legislate or legislate in a way that applies equally. So, without an independent judiciary, the democratic legitimacy of a legislature is weakened or disappears. This argument makes a legal difference, but the kind of legal difference it makes varies between jurisdictions. This paper focuses on one difference the democratic legitimacy of judges makes in the UK: the extent to which Parliament can oust judicial review for error of jurisdiction.
