The Independent Commission on Referendums, established by the Constitution Unit to review the role of referendums in UK democracy, has now met twice. One of the issues they are considering is rules for how referendums should work in practice. The Commission’s Research Assistant, Jess Sargeant, summarises the issues for consideration.
In a previous blog post I explored some principles that could be used for deciding when a referendum might be appropriate. The Independent Commission on Referendums is also considering how referendums should work in practice. The following post explores some key practical questions.
Should there be rules for when a referendum is required, permitted or prohibited?
The UK is unusual among comparable democracies in that referendums are held ad hoc: there are very few standing rules on when referendums are to be held. This means, at least in theory, that there are no restrictions on matters that a referendum may be held on: it could be held on any issue within parliament’s legislative competence.
Many other democracies have provisions in their constitutions setting out when a referendum must be, can be, or cannot be held. Constitutional issues are the most common category of issues on which a referendum is required. For example, Ireland, Australia and Japan require referendums on any bills amending the constitution. In Austria, Spain, Lithuania and Iceland amendments to certain key parts of the constitution must be approved in a popular vote. There are also examples of referendums being required on other issues: Denmark has mandatory referendums on transfers of sovereignty and changes to the voting age.
Where referendums are not required on constitutional amendments, there is often a mechanism allowing a parliamentary minority to trigger one, as is the case in Italy, Austria and Spain. In some democracies, legislation can be put to a referendum if requested by a body so empowered by the constitution. This could be the parliament, as in Denmark and Austria, the president, as in Ireland and Iceland, or groups of citizens, as in Italy and the Netherlands. Where referendums are permitted on legislation, certain types of legislation are often exempt: most commonly, finance, budgetary and tax laws or legislation implementing treaties.
