Impeached president avoids investigators as court case to decide fate begins

South Korea’s impeached President Yoon Suk Yeol has dodged requests by investigative agencies to appear for questioning over his short-lived martial law decree.

It comes as the Constitutional Court began its first meeting on Monday on Mr Yoon’s case to determine whether to formally unseat or reinstate him.

A joint investigative team involving police, an anti-corruption agency and the defence ministry said it wants to question Mr Yoon on charges of rebellion and abuse of power in connection with his ill-conceived power grab.

Agency investigator Son Yeong-jo cited presidential secretarial staff at Mr Yoon’s office as claiming they were unsure whether conveying the request to the impeached president was part of their duties.

Mr Son said his team had also mailed the request to Mr Yoon, but declined to provide specifics when asked how investigators would respond if Mr Yoon refuses to appear.

Mr Yoon was impeached by the opposition-controlled National Assembly on Saturday over his December 3 martial law decree.

His presidential powers have been subsequently suspended, and the Constitutional Court is to determine whether to formally remove him from office or reinstate him.

If Mr Yoon is dismissed, a national election to choose his successor must be held within 60 days.

Mr Yoon has justified his martial law enforcement as a necessary act of governance against the main liberal opposition Democratic Party that he described as “anti-state forces” bogging down his agendas and vowed to “fight to the end” against efforts to remove him from office.

Hundreds of thousands of protesters have poured onto the streets of the country’s capital, Seoul, in recent days, calling for Mr Yoon’s ouster and arrest.

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

Repeated calls to a prosecutors’ office in Seoul were unanswered.

Mr Yoon’s presidential security service has also resisted a police attempt to search Mr Yoon’s office for evidence.

The Constitutional Court on Monday met for the first time to discuss the case.

The court has up to 180 days to rule but observers say a ruling could come faster.

In the case of parliamentary impeachments of past presidents — Roh Moo-hyun in 2004 and Park Geun-hye in 2016 — the court spent 63 days and 91 days respectively before determining to reinstate Mr Roh and dismiss Mr Park.

Kim Hyungdu, a court justice, told reporters earlier on Monday that the court will “swiftly and fairly” make a decision in the case.

He said Monday’s court meeting was meant to discuss preparatory procedures and how to arrange arguments at formal trials.

Upholding Mr Yoon’s impeachments needs support from at least six out of the court’s nine justices, but three seats are vacant now.

This means a unanimous ruling by the court’s current six justices in favour of Mr Yoon’s impeachment is required to formally end his presidency.

Mr Kim said he expected the three vacant seats to be filled by the end of this month.

Prime Minister Han Duck-soo, who became the country’s acting leader after Mr Yoon’s impeachment, and other government officials have sought to reassure allies and markets after Mr Yoon’s surprise stunt paralysed politics, halted high-level diplomacy and complicated efforts to revive a faltering economy.

Democratic Party leader Lee Jae-myung urged the Constitutional Court to rule swiftly on Mr Yoon’s impeachment and proposed a special council for policy cooperation between the government and parliament.

Mr Yoon’s conservative People Power Party criticised Mr Lee’s proposal for the special council, saying that it is “not right” for the opposition party to act like the ruling party.

Mr Lee, a firebrand legislator who drove a political offensive against Mr Yoon’s government, is seen as the frontrunner to replace him.

Mr Yoon’s December 3 imposition of martial law, the first of its kind in more than four decades, harkened back to an era of authoritarian leaders the country has not seen since the 1980s.

Mr Yoon was forced to lift his decree hours later after parliament unanimously voted to overturn it.

He sent hundreds of troops and police officers to the parliament in an effort to stop the vote, but they withdrew after the parliament rejected Mr Yoon’s decree.

Opposition parties have accused Mr Yoon of rebellion, saying a president in South Korea is allowed to declare martial law only during wartime or similar emergencies and would have no right to suspend parliament’s operations even in those cases.
