The impeachment of President Park Geun-hye of South Korea in response to a major political scandal is unanimously upheld by the country's Constitutional Court, ending her presidency.
The impeachment of Park Geun-hye, President of South Korea, was the culmination of a political scandal involving interventions to the presidency from her aide, Choi Soon-sil. The impeachment vote took place on 9 December 2016, with 234 members of the 300-member National Assembly voting in favour of the impeachment and temporary suspension of Park Geun-hye's presidential powers and duties. This exceeded the required two-thirds threshold in the National Assembly and, although the vote was by secret ballot, the results indicated that nearly half of the 128 lawmakers in Park's party Saenuri had supported her impeachment. Thus, Hwang Kyo-ahn, then Prime Minister of South Korea, became Acting President while the Constitutional Court of Korea was due to determine whether to accept the impeachment. The court upheld the impeachment in a unanimous 8–0 decision on 10 March 2017, removing Park from office. The regularly scheduled presidential election was advanced to 9 May 2017, and Moon Jae-in, former leader of the Democratic Party, was elected as Park's permanent successor.
Park was formally sentenced to 24 years in prison on 6 April 2018 after being found guilty of abuse of power and coercion. This was later raised to 25 years and a fine of ₩20 billion (US$17.86 million) following an appeal by prosecutors.
