- Spoilt vote
-
In voting, a ballot is considered to be spoilt, spoiled, void, null, informal or stray if it is regarded by the election authorities to be invalid and thus not included in the tally during vote counting. This may be done accidentally or deliberately. The total number of spoilt votes in a United States election has been called the residual vote.[1]

Types of spoiled vote
Ways of spoiling a ballot include:
- an undervote: leaving sections of the ballot blank, or marking nothing at all (though some ballots include an explicit "none of the above" option)
- completing the ballot in an illogical or unapproved manner, such as:
- an overvote: casting more than the permitted number of votes, for example, more than one vote in a plurality voting system
- filling a preference ballot out of sequence, e.g. 1-2-2-3-4 or 1-2-4-5-6
- filling the ballot in a manner that makes the voter's decision incomprehensible.
- physically deforming ballots, especially those counted by machine
- making marks on the ballot other than those necessary to complete it, where the voter's identity can be ascertained, compromising the secrecy of the ballot
If a voter makes a mistake while completing a ballot, it may be possible to cancel it and start the voting process again. In the United States, cancelled physical ballots may be called "spoiled ballots",[2] as distinct from an "invalid vote" which has been cast. In Canada, the same categories are called "rejected ballots" (given back to the deputy returning officer without a mark or otherwise spoilt, so as not to go into the ballot box), and "spoilt ballots" (ballots from inside the box where intent is unclear, the voter can be identified, or the ballot is otherwise incorrectly marked).
In many jurisdictions, if multiple elections or referenda are held simultaneously, then there are separate physical ballots for each, which may be printed on different-colored paper and posted into separate ballot boxes. In the United States, a single physical ballot is often used to record multiple separate votes. In such cases one can distinguish an "invalid ballot", where all votes on the ballot are rendered invalid,[3] from a "partially valid" ballot, with some votes valid and others invalid.
Unintentional spoiling
Voter instruction is intended to minimise or even preclude accidental spoiling of votes. Ballot design can aid or inhibit clarity in an election, resulting in less or more accidental spoiling. Some election officials have discretion to include ballots where the strict criteria for acceptability are not met but the voter's intention is clear. More complicated electoral systems may be more prone to errors. Group voting tickets were introduced in Australia owing to the high number of informal votes cast in single transferable vote elections.
The United States Election Assistance Commission's survey of the 2006 midterm elections reported undervoting rate of 0.1% in US Senate elections and 1.6% in US House elections; overvotes were much rarer.[4] Some paper-based voting systems and most DRE voting machines can notify voters of under-votes and over-votes. The Help America Vote Act requires that voters are informed when they have overvoted, unless a paper-ballot voting system is in use.[5]
The percentage of accidentally spoilt votes is lowest when the ballot requires voting for only one candidate[dubious ]. Designs such as the butterfly ballot, which alternate candidates between one side and the other with the place to be marked along the seam of the ballot, can make mistakes and spoiled ballots more likely.
Intentional spoiling
Spoiled votes may be the result of a deliberate act by the voter; some proportion are likely to be protest votes, especially in systems where voting is compulsory. Intentionally spoiling someone else's ballot before or during tabulation is a method of election fraud.
The validity of the election may be questioned if there is an unusually high proportion of spoilt votes. However, in countries such as the UK where spoilt ballots are counted, some voters will deliberately spoil their ballot paper to show disapproval of the candidates available whilst still taking part in the electoral process. This may include signing or printing the voter's name on the ballot slip. Evidence points that this practice dates back to times when electoral wards were assigned a designated scīrgerefa (Old English) or "sheriff" a royal official responsible for keeping the peace throughout a shire or county on behalf of the king and who would pay royalties to those who had shown their support.
In multiple-vote U.S. ballots, "voter roll-off" is calculated by subtracting the number of votes cast for a "down-ballot" office, such as mayor, from the number of votes cast for a "top-of-the-ballot" office, such as president. When the election jurisdiction does not report voter turnout, roll-off can be used as a proxy for residual votes. Some voters may only be interested in voting for the major offices, and not bother filling in the lower positions, resulting in a partially valid ballot.
