President Yoon Suk Yeol on Thursday attended what is likely the final hearing of his impeachment trial over his short-lived imposition of martial law in December.

Yoon and other witnesses, including National Intelligence Service Director Cho Tae-yong, appeared for the eighth formal hearing of the trial at the Constitutional Court in central Seoul, a month after the first session took place on Jan. 14.

Thursday's hearing took place as the court has yet to schedule additional dates for the trial's oral arguments, raising the possibility that they could end on the day.

Should oral arguments conclude Thursday, a final decision on whether to uphold Yoon's impeachment or reinstate him is expected to be made in early March.

The court can still schedule one or two more hearing dates if deemed necessary, but it has so far said that nothing has been decided over additional hearings.

If additional hearings are scheduled, the court is expected to reach a decision by mid-March.

In the impeachment trials of former Presidents Roh Moo-hyun and Park Geun-hye, the court announced its decisions about two weeks after oral arguments ended. (Yonhap)
