South Korea’s Constitutional Court ruled unanimously on Friday to permanently remove President Yoon Suk-yeol from office, following his controversial imposition of martial law in December — a move deemed a serious violation of the country’s constitution and democratic norms.

This landmark decision marks one of the most dramatic political shakeups in the nation’s history, immediately stripping Yoon of his presidential powers. South Korea’s Prime Minister will assume interim leadership until a new election is held.

President Yoon had faced intense criticism after declaring martial law amid what he described as security concerns. The move was met with backlash from opposition parties, civil society groups, and legal experts, leading to a formal constitutional challenge.

The court’s ruling was welcomed by large segments of the political class and the general public, who hailed it as a victory for democracy and the rule of law. The interim government has since called for calm and national unity during the transition period.
