South Korea ’s Supreme Court overturned on Thursday an earlier ruling that had cleared election front runner Lee Jae-myung of election law violation, throwing into doubt his eligibility to run for the presidency.

South Korea’s Supreme Court ruled that presidential candidate Lee Jae-myung violated election law and sent the case back to the high court for final sentencing, in a move that potentially upends the race for the country’s next leader.

The Supreme Court overturned Lee Jae-myung's acquittal on election law charges, leading to a retrial while preserving his candidacy ahead of the June 3 presidential election.
