SEOUL, South Korea — South Korea’s Constitutional Court says it has begun its first meeting on the impeachment of President Yoon Suk Yeol.

South Korea’s opposition-controlled parliament on Saturday vowed to impeach Yoon over his short-lived martial law this month.

Yoon’s presidential powers have been suspended. Constitutional Court has up to 180 days to determine whether to dismiss Yoon from office or restore his presidential powers.

The court says its first meeting on Yoon’s impeachment began on Monday morning as scheduled. It gave no further details.
