South Korean prosecutors have formally indicted former President Yoon Suk Yeol on abuse of authority charges, according to a Thursday report by Yonhap News Agency.
The new indictment compounds Yoon’s legal troubles as he already faces an ongoing insurrection trial related to his controversial imposition of martial law during December’s political crisis.
The dual prosecutions mark an unprecedented legal reckoning for a former South Korean leader, with the abuse of power charges stemming from separate allegations of presidential overreach during his administration.

Martial Law Controversy Haunts Former Leader as Legal Woes Mount
The insurrection trial, which began earlier this year, centers on Yoon’s dramatic December decision to declare martial law amid mass protests – a move constitutional scholars called legally dubious.
Prosecutors allege the 48-hour military intervention violated democratic norms and constituted an attempted coup. Thursday’s additional indictment suggests investigators have uncovered broader patterns of authoritarian behavior during Yoon’s presidency, though specific details of the new charges remain sealed under judicial procedure.
This makes it the first time in South Korea’s modern history that a former president faces simultaneous criminal trials for separate constitutional violations. Legal analysts note the cases will test the nation’s judicial independence, given Yoon’s continued influence among conservative factions.
The indictments come just months before pivotal parliamentary elections, injecting new volatility into South Korea’s already polarized political landscape. Justice Ministry officials declined to comment on whether further charges might be forthcoming as their investigation continues.
What Happens Now
With both cases expected to stretch through election season, the twin prosecutions guarantee ongoing scrutiny of presidential power limits in Asia’s fourth-largest economy.
Court observers suggest the abuse of authority charges may focus on Yoon’s alleged weaponization of anti-corruption agencies against political rivals. As the first South Korean leader to face such legal consequences since the country’s democratic transition, Yoon’s fate could set powerful precedents for executive accountability in the region.
