Voting has been compulsory in Singapore since 1959 and there is universal suffrage. The legal voting age is 21. The Elections Department of Singapore is responsible for the planning, preparation and conduct of presidential and parliamentary elections and of any national referendum in Singapore. It is a department under the Prime Minister's Office.
Paper ballots are still used in Singapore. However, there is a concern[citation needed] that voting secrecy might be compromised as ballot papers have serial numbers on them. As stated in the Elections Department website:
"...ballot papers can be examined only under strict conditions, and there are safeguards that make it extremely difficult to find out how any particular voter voted. After the count, all ballot papers and their counterfoils have to be sealed in the Supreme Court vault for six months, after which all the ballot papers and other election documents are destroyed. During those six months, these documents can only be retrieved by court order. The court will issue such an order only if it is satisfied that a vote has been fraudulently cast and the result of the election may be affected as a result. Our courts have issued no such order since elections have been held here since 1948.
