The South Korean parliament voted to impeach the president on December 9 in the wake of an influence-peddling scandal involving Park's "shadow adviser" Choi Soon-sil. Choi, who does not hold any official posts in the government or the president's administration, was accused of abuse of power after it was revealed she edited the president's speeches. Choi denied the allegations.
The Constitutional Court has now six months to decide upon the validity of the parliament's impeachment of Park. If the impeachment is recognized as valid, presidential elections should be called within two months.
