South Korea’s indicted President Yoon Suk Yeol could become the country’s first sitting president to face arrest after a court issued an arrest warrant for him, domestic media reported.

The Seoul Western District Court issued the arrest warrant for Yoon, the Korea Times reported, after he failed to appear for questioning despite multiple summonses from a joint investigation unit consisting of South Korea’s police and the senior officials’ corruption investigation bureau.

The arrest warrant authorizes the CIO to take Yoon into custody for questioning within 48 hours.

According to a Google translation of a Yonhap report in Korean, Yoon’s legal team said it plans to file an injunction with the Constitutional Court to suspend the issuance of the arrest warrant. A legal representative for Yoon said the arrest warrant was “unlawful and invalid” because the investigation into the insurrection allegations was outside the CIO’s jurisdiction.

A separate warrant allows the CIO to search Yoon’s apartment. According to Yonhap News Agency, the presidential security service has blocked access to the president’s office compound and Yoon’s official residence, citing security concerns.

South Korean presidents do not enjoy immunity from charges of insurrection or treason. In addition, according to CIO chief Oh Dong-woon, presidents are not allowed to obstruct a court-issued detention or arrest warrant.

Yoon is charged in connection with the Dec. 3 declaration of a martial law state of emergency, which he argued was necessary to protect the constitution. He lifted martial law within six hours after the country’s National Assembly voted to repeal his decree.

Yoon was impeached by lawmakers on December 14, with members of his People Power Party voting in favor of the motion. In an earlier vote, a two-thirds majority was not achieved.

South Korea’s Constitutional Court has begun proceedings to decide whether Yoon should be removed from office or reinstated, Yonhap reported. It will announce its decision within 180 days from December 14.

While the impeachment suspends Yoon from his duties and powers as head of state, he remains president while the Constitutional Court considers his case.

After Yoon’s removal from office, Prime Minister Han Duck-soo took over as president.

However, Han was also charged last week. The opposition Democratic Party accused him of being unwilling to immediately appoint three judges to the Constitutional Court.

Chio Sang-mok, deputy prime minister and finance minister, became acting president on December 27 following Han’s ouster.
