Ex-Lawmaker’s Sentence for Encouraging Revolt Is Upheld in South Korea

SEOUL, South Korea — South Korea’s Supreme Court on Thursday upheld a nine-year prison sentence for a former lawmaker who was convicted of encouraging followers to take up arms to overthrow the government in the event of war with North Korea.

Lee Seok-ki, whose small, leftist United Progressive Party was disbanded by a court last month, was arrested in 2013 on charges including treason. It was the first time such a charge had been brought against a South Korean legislator since the country emerged from military dictatorship decades ago.

Mr. Lee’s United Progressive Party was disbanded in December by order of the Constitutional Court, which also stripped Mr. Lee and the party’s four other lawmakers of their seats in Parliament.
