- most direct form of democracy - society's view on an issue is clearly indicated. Politicians cannot simply claim to be representing public opinion. A referendum helps to make decisions legitimate and confirms the principle of government by consent.
- society is more likely to accept the decision - if the people have demonstrated their expressed consent they are more likely to agree with the resulting policies and allowing stable government of the people.

- can prevent government from making unpopular decisions - a 'no' vote will show the discontent of the people and ensure that government still works within the consent of the people. For example, North-East Assembly 2004 rejected the idea of regional assemblies in the UK, with the North-East as the trial assembly.
- can resolve issues which government and individual parties are unlikely to be able to resolve easily - this allows government to remain stable and limits the chance of a crisis of confidence. For example, EEC Membership 1975 stopped the Labour government from collapsing.
- entrenches constitutional changes - it protects the decisions made in the referendum from attacks by a future government whose policies may only short term.

For example, Scottish Devolution 1997 means that it would be extremely hard for a future government to remove their power.
- Plato argued that people will not respect the decisions that they make themselves - many people prefer to be led, especially if they believe that their elected representatives can do a better job. What other reason is there to have elected representatives if they still rely on the people…
