SEOUL, South Korea — South Korean law enforcement authorities are pushing to summon impeached President Yoon Suk Yeol for questioning over his short-lived martial law decree as the Constitutional Court began its first meeting Monday on Yoon’s case to determine whether to remove him from office or reinstate him.

A joint investigative team involving police, an anti-corruption agency and the Defense Ministry said it plans to convey a request to Yoon’s office that he appear for questioning on Wednesday, as they expand a probe into whether his ill-conceived power grab amounted to rebellion.

Yoon was impeached by the opposition-controlled National Assembly on Saturday over his Dec. 3 martial law decree. His presidential powers will be suspended until the Constitutional Court decides whether to formally remove him from office or reinstate him. If Yoon is dismissed, a national election to choose his successor must be held within 60 days.

It remains unclear whether Yoon will grant the request by investigators for an interview.
