Plural voting is the practice whereby one person might be able to vote multiple times in an election. It is not to be confused with a plurality voting system which does not necessarily involve plural voting. Weighted voting is a generalisation of plural voting.
In the United Kingdom, up to 1948, people affiliated with a university were allowed a vote in both a university constituency and their home constituency, and property owners could vote both in the constituency where their property lay and that in which they lived, if the two were different. Therefore some university-educated property owners could vote in three different constituencies. After 1910, the Liberal Government was intent on passing a Plural Voting Bill that sought to prevent electors who appeared on the electoral register more than once from voting more than once. Liberal and Unionist Headquarters were in agreement that 29 seats were won by Unionists in December 1910 because of plural voting. However, before the bill could pass through Parliament, the Great War started and the bill was shelved. These practices were finally abolished by the Representation of the People Act 1948, which first applied in the 1950 General Election.
Until the Electoral Law Act 1968 took effect in 1969, the Queen's University, Belfast constituency was retained in the Parliament of Northern Ireland and owners of businesses were allowed to cast more than one vote. Tim Pat Coogan wrote on this subject:
Limited companies and occupiers of premises with a rateable valuation of £10 could appoint nominees – as could companies for each £10 of their valuations – under a system of plural voting, which even allowed such votes to be cast in another constituency ...
In Belgium, plural voting was introduced in 1893 and applied for elections from 1894 to 1919 as a way to limit the impact of universal suffrage.
- holder of a school diploma;
- family head over 30, paying a poll tax of at least five francs;
- holder of a savings account of at least 2,000 francs, or beneficiary of a life annuity of at least 100 francs.
For municipal elections, a fourth vote was granted to family heads who paid a fixed level of electoral tax, or whose cadastral income was at least of 150 francs.
The Local Government (Dublin) Act 1930, passed by the Cumann na nGaedheal government, provided that Dublin City Council would comprise 30 popularly elected "ordinary members" and five "commercial members" elected by business ratepayers (individuals or corporate persons). The commercial members were elected by single transferable vote in a single five-member constituency, with each elector casting between one and six ballots depending on the rate they paid. The commercial members were abolished in 1935 by the Fianna Fáil government.
It has been proposed that a parent should get a vote for each dependent child, to increase the birth rate or to increase the importance of long-term planning as an election issue. This was proposed in France in 1871 by Louis Henri de Gueydon; in the UK in 2003 by Demos, and in 2007 by Dutch economist Lans Bovenberg. It is a policy of the Christian Party of Austria and has been proposed by some members of Law and Justice in Poland.
