South Korea’s Constitutional Court will rule Friday on whether to formally dismiss or reinstate impeached President Yoon Suk Yeol — a decision that either way will likely deepen domestic divisions.

The Constitutional Court will announce on Friday whether Yoon Suk Yeol, who was impeached in December for declaring martial law, will be permanently removed from office or restored to power.

The court has been deliberating on Yoon’s political fate over his ill-fated imposition of martial law that triggered a massive political crisis.
