You may have seen or heard of voters spoiling their votes as a form of protest
In 2018, the #UndiRosak campaign encouraged voters to spoil their ballot papers as a boycott. The idea was to show dissatisfaction by turning up to vote but deliberately marking the ballot wrongly, instead of staying away from the ballot box.
But does a spoiled vote actually result in anything?
First, it's important to note that the Election Commission (EC) officially distinguishes between 'spoilt ballots' (undi rosak) and 'rejected ballots' (undi ditolak)
| Term | Malay term | What it means | When it happens |
|---|---|---|---|
| Spoilt ballot | Undi rosak | A ballot paper that is faulty, damaged or cancelled before it goes into the ballot box | Before the ballot is cast |
| Rejected ballot | Undi ditolak | A ballot paper found in the ballot box but rejected during counting because the voter's choice is invalid or unclear | After the ballot is cast |
In everyday conversation, people often say they want to "spoil" their vote as a form of protest.
Technically, if a voter deliberately marks the ballot wrongly and places it into the ballot box, the outcome is usually a rejected ballot, not a spoilt ballot.
A spoilt ballot usually refers to a ballot paper that is dealt with before it is cast. For example, the ballot may be torn, missing the required official marking, already marked, or cancelled through the polling-station process.
In terms of election results, no. Whether a ballot is marked invalid on purpose or by accident, once it is rejected during counting, it does not count for any candidate. It may still appear in election statistics, but it will not help elect anyone.
What does it mean to "spoil" your vote?
In practice, people often say "spoiling" your vote when they mean a ballot that ends up rejected. A rejected ballot is one that is marked in a way that does not clearly show one valid choice, or breaks EC rules on how the ballot can be marked.
This can include:
- Leaving the ballot blank
- Marking more than one candidate
- Writing extra words on the ballot
- Drawing symbols that make your choice unclear
- Damaging the ballot paper
ㅤ
The Election Commission (EC), or Suruhanjaya Pilihan Raya Malaysia, has advised voters to avoid writing words, numbers, or drawings on the ballot paper because it may cause the ballot to be rejected.
Is spoiling your vote illegal?
It is not illegal, but voters should know that a rejected ballot is not counted for any candidate.
If your ballot is rejected, it does not help elect a candidate. If you want your vote to count for someone, mark your ballot clearly according to the voting instructions.
Is spoiling your vote an effective way to show dissatisfaction towards the government?
A spoiled vote may be a personal form of protest, but if the ballot is rejected during counting, it goes into the rejected-ballot total. Results do not usually separate intentional protest votes from accidental mistakes.
In Malaysia, rejected ballots usually account for around 1% to 1.5% of total votes, so they are hard to read as a clear political message unless the number is unusually high.
One major international example was Cambodia's 2018 general election, where invalid votes made up about 8% of total votes cast. That stood out because the number was unusually large.
Can you ask for a new ballot if you made a mistake?
If you make a mistake before placing the ballot in the box, speak up immediately. In EC terms, this is treated as a "spoilt" ballot (undi rosak) and can be cancelled and replaced, so it never goes into the box.
Do not tear, throw away, hide or destroy the ballot paper yourself. Return it to the polling station chief and follow the official process. Once the ballot is inside the ballot box, you generally cannot take it back.
What should first-time voters remember?
If you want your vote to count, make one clear mark for one candidate.
Use the pen provided and mark the box beside your chosen candidate clearly. A clear "X" is the safest option. Do not use indelible ink, your thumbprint, extra symbols, comments, or multiple marks that could make your choice unclear.
Frequently asked questions
Does a rejected ballot count for any candidate?
No. A rejected ballot does not count for any candidate.
Can I leave my ballot blank?
You can, but a blank ballot will not count for any candidate.
Can I write a protest message on my ballot?
You should avoid writing words, numbers or drawings on the ballot paper because it may cause the ballot to be rejected.
What if I spoil my ballot by accident?
Tell the Ketua Tempat Mengundi before placing it in the ballot box. Do not destroy or discard the ballot yourself.
Is not voting the same as "spoiling" your vote?
No. Not voting means you do not cast a ballot. Having your ballot rejected means you cast a ballot that is later found invalid during counting. Both mean your vote does not count for any candidate.
