1987 South Korean presidential election

Under the presidency of Chun Du-Hwan, the constitution was rewritten to maintain his power and restrict the presidency to a single seven-year term, and legislation such as the Basic Press Law, which closed hundreds of media organizations, was passed.[4] However, following the success of the opposition New Korea and Democratic Party (NKDP) in the National Assembly election on 12 April 1985, calls were made for constitutional revision. On 13 April 1986, Chun made a speech defending the current version of the constitution, in which he stated that the successor to the presidency would be a member of his own party, the Democratic Justice Party (DJP), and that any discussion of constitutional debate would be put off until the end of the 1988 Olympics in South Korea.[4] In its argument, the DJP argued that the opposition was splintered, and could not act as a negotiating partner. They believed that political uncertainty would injure both the Olympic setup and the upcoming election.[5]

Nearly a month later on 10 June, mass protests broke out as Roh Tae Woo was announced successor to the presidency as the then chair of the DJP.[3] The public nature of the announcement and the death of a university student who was tortured by the police triggered protests across Korea.[3] In the following weeks, multiple protests were held, and on 29 June, the DJP candidate Roh Tae Woo capitulated to demands for constitutional amendments, proposing an eight-point plan. It included the following concessions:

• Direct participation in upcoming presidential election for all citizens over age 20
• Freedom of candidacy and fair competition
• Amnesty for Kim Dae-jung and other political prisoners
• Protection of human dignity and promotion of basic human rights
• Freedom of the press and abolishment of the restrictive Basic Press Law (see: Media of South Korea)
• Educational autonomy and local self-government
• The creation of a new political climate for dialogue and compromise
• Commitment to enact bold social reforms to build a clean, honest, and more just society.

The new constitutional amendment was ratified by the National Assembly on 12 October, and was submitted to a referendum to the South Korean public on 27 October. 93% of voters cast ballots in favor of the amendment, which permitted the direct, democratic election of the 6th President of South Korea.[4]

The Democratic Justice Party (DJP) National Convention was held on 10 June at Jamsil Gymnasium in Seoul.. At the convention, 7,378 delegates nominated former Commander of Capital Defense Roh Tae-woo, who was the only option on the ballot paper, for president.[6]

The New Democratic Republican Party (NDRP) National Convention was held on 30 October at Heungsadan Hall in Seoul. Kim Jong-pil, former prime minister and former five-term lawmaker from South Chungcheong, was chosen as the party's candidate.[7]

The Reunification Democratic Party (RDP) National Convention was held on 9 November at Sejong Center for Performing Arts in Seoul. Kim Young-sam, a former seven-term lawmaker from Busan, was nominated for president by the acclamation of 1,203 delegates.[8]

The Peace Democratic Party (PDP) National Convention was held on 12 November at Sejong Center for Performing Arts in Seoul. Kim Dae-jung, a former four-term lawmaker from South Jeolla and 1971 presidential candidate, was nominated for president.[9]

According to Lynn Turk, at the time a Seoul-based US State Department foreign service officer who watched the campaign and the election closely on a moment-to-moment basis noted the allegations as “a very interesting story”, but stated “the votes were counted fairly and Roh really did win fair and square.” She added: “On election night each of the four parties had observers at each polling place and got a carbon copy of the public hand-counted vote. So the totals their command posts registered matched the official count.”[11]

Park Chul-un, brother-in-law and aide to Roh Tae-woo, said ‘no election fraud was planned or carried out’ in the 1987 election in response to the SCMP report.[12]
