Referendum vs Initiative vs Plebiscite: The Differences

The short answer: in a referendum, voters decide on a text that comes from parliament or government. In an initiative, citizens draft a proposal themselves and, after collecting enough signatures, force a debate or a public vote on it. A plebiscite is usually a vote called from the top by government or the head of state, often without binding force. The exact meaning of these words varies from country to country, so it is worth looking at who starts the process and what the vote can change.

The instruments compared

Instrument	Who starts it?	Where does the text come from?	Is there a public vote?	Effect
Mandatory referendum	The constitution	Parliament	Yes, always	Usually binding
Optional referendum (citizen-triggered)	Citizens, by signatures	Parliament (an adopted law)	Yes, if enough signatures	Binding; can stop a law
Referendum called by authorities / plebiscite	Government, head of state or parliament	The authorities	Yes	Binding or advisory
Popular (full) initiative	Citizens, by signatures	Citizens	Yes, if parliament does not adopt it	Binding if approved
Agenda initiative	Citizens, by signatures	Citizens	No	Parliament or executive must consider it
Petition	Anyone	Anyone	No	Usually no formal obligation
Recall	Citizens, by signatures	–	Yes	Removes an official

Referendum

The defining feature of a referendum is that the question comes from the institutions. Parliament has adopted a law or treaty, or wants to change the constitution, and the electorate is asked to approve or reject it. Citizens can sometimes trigger the vote themselves, as with Switzerland’s optional referendum, but they do not write the text. Types and thresholds are explained in What is a referendum?.

Initiative

In an initiative, the text comes from citizens. There are two main forms:

• Full (popular) initiative: if a proposal collects enough signatures, it goes to a public vote, often with a counter-proposal from parliament. Switzerland is the leading example at federal level; several German states and many Swiss cantons have similar procedures.
• Agenda initiative: a proposal with enough signatures must be considered by parliament or the executive, but there is no automatic public vote. Austria’s ‘Volksbegehren’ and the European Citizens’ Initiative work this way.

Some systems combine both, so that a successful agenda initiative which parliament rejects can lead to a public vote in a second stage.

Plebiscite

‘Plebiscite’ is the least precise of the terms. It is often used for votes initiated by the executive, for example on questions of sovereignty, territory or confidence in a leader. In some languages and countries it is simply a synonym for referendum. In political science, the term often signals that the vote was called by those in power on a timing and question of their choosing. Because usage varies, it is best to check what the relevant constitution actually calls the procedure.

Petition and recall

A petition asks an authority to do something. Many parliaments have petition committees, and the European Parliament accepts petitions from EU citizens and residents. A petition can lead to a hearing, but it does not force a vote.

A recall lets voters end an elected official’s term early. It is well known from some US states but rare in Europe.

Where citizens’ assemblies fit in

Citizens’ assemblies are not votes at all. A randomly selected group deliberates and makes recommendations, which may later be put to parliament or to a referendum, as happened in Ireland. See citizens’ assemblies.

Why the distinction matters

• Who sets the agenda? In a referendum, the institutions; in an initiative, citizens.
• What is at stake? A referendum usually approves or blocks something already decided; an initiative proposes something new.
• How binding is the result? This depends on the legal basis, not on the name.

If you are comparing countries, the instruments available at national, regional and local level differ widely. Our country overview of referendums in Europe summarises the main rules.

A note on terms in other languages

German distinguishes Volksinitiative, Volksbegehren and Volksentscheid, which follow one another as stages in several German states, while in Switzerland a Volksinitiative is the full initiative leading to a vote. French uses référendum d’initiative populaire or initiative populaire. Translating these terms one to one into English can be misleading, so official texts usually describe the procedure rather than relying on the label.
