South Korea’s Supreme Court has ordered a retrial of Samsung’s de facto leader Lee Jae-yong, reigniting a bribery case that could send the technology heir back to prison.

Lee was found guilty of bribery and other corruption charges in 2017 but was freed when an appeals court threw out some of the charges and suspended his sentence.

The Supreme Court’s decision sends the case back to an appellate court for retrial.

Lee is the vice chairman of Samsung and the son of ailing chairman Lee Kun-hee. The corruption scandal was dubbed the “trial of the century” and gripped South Korea for months. It was part of a huge influence-peddling scandal that brought down the country’s former president, Park Geun-hye.

Lee’s part of the case is significant, because he is de facto head of Samsung, the world’s largest smartphone and memory chip manufacturer.
