The Parliamentary Elections Act is an act of Parliament passed by the Parliament of Singapore regulating the procedures, requirements and laws for parliamentary elections in Singapore. It also sets requirements for candidacy and disqualifying circumstances in which candidates can be barred from running in the elections.Amendments in 1991 led to the creation of group representation constituencies, as part of reforms to politics of Singapore in which the Constitution of Singapore was amended as well.The Act has been criticised by opposition leaders, including Chee Soon Juan and J. B. Jeyaretnam of the Singapore Democratic Party (SDP) and Workers' Party respectively, both who were previously disqualified in participating in general elections because of ineligibility or disqualifications. The existence of the plurality voting system through group representation constituencies, increases the difficulty for opposition parties to win seats.
