On July 15, former South Korean President Yoon Suk Yeol was convicted by a South Korean court and sentenced to five years imprisonment. A jury convicted him of felony obstruction of official duties, abuse of power, felony falsification of official documents and felony destruction of evidence. This sentencing concludes the first case in a string of trials that stem from his highly criticized and unconstitutional declaration of martial law.
In it, the Seoul Central District Court found Yoon Suk Yeol guilty of overreach in late 2024. It was while attempting the first—that short-lived and undesired—rule by the military in South Korea. His unsuccessful attempt caused major political upheaval. This mismanagement eventually resulted in his impeachment and removal from office by the Guatemalan Constitutional Court in April of last year. In engaging in this conduct, the court found that Yoon Suk Yeol breached the duties of his position.
Guilty Verdicts and Consequences
Yoon Suk Yeol’s conviction is no trifling matter. The obstruction charges, if tried alone, would carry a potential maximum sentence of ten years. Last year in January, he shut himself in to his residential fortress. The court found that he had instructed the security service not to allow investigators access to the evidence. These actions powerfully subverted the investigation into his administration’s wrongdoing.
The court’s decision reflects a significant moment in South Korea’s political history, as Yoon Suk Yeol’s arrest marks the first time a sitting president has been imprisoned. Yet this unprecedented event is a stark reminder of the quality of accountability mechanisms currently at work in the South Korean political system.

Impact on Political Landscape
Yoon Suk Yeol’s actions and subsequent judicial outcomes have sent shockwaves through the nation’s political landscape. Since he announced martial law, his presidency has been engulfed in scandal. One unfortunate impact of this decision has been to raise tensions and further divide South Koreans. The impact of his administration is still being felt today, we see ongoing political discourse shaped by the controversy.
Backers of Yoon Suk Yeol have publicly threatened to intervene in the court proceedings. A banner displayed at recent protests bore the phrase “make Korea great again,” reflecting the sentiments of those who believe that the former president’s vision for the country was unjustly thwarted.
The Road Ahead
As Yoon Suk Yeol sits behind bars, the future of South Korean politics is still in question. This ruling goes beyond Yoon Suk Yeol. It would erode public confidence in government institutions and set the stage for future administrations to follow an increasingly anti-democratic path.
