South Korean law enforcement will request that impeached President Yoon Suk Yeol appear for questioning this week over his controversial martial law decree, authorities said Monday.

A joint team, including police, anti-corruption officials, and the Defense Ministry, plans to request Yoon’s presence on Wednesday for questioning. The move comes days after Yoon was impeached by the opposition-led National Assembly over his controversial December 3 decree, which has triggered political chaos and massive protests.

Yoon’s presidential powers are suspended while the Constitutional Court decides whether to remove him from office permanently. Prime Minister Han Duck-soo is acting as the country’s leader during this time.

Defending his actions, Yoon claimed the decree was essential to combat “anti-state forces” hindering his administration. He has vowed to “fight to the end,” even as hundreds of thousands of protesters demand his resignation and arrest.

Prosecutors had earlier asked Yoon to appear for questioning on Sunday, but he declined. His office has also blocked a police search of the presidential compound.

The Constitutional Court, which began deliberations Monday, has up to six months to rule, though decisions in similar cases—such as those involving former presidents Roh Moo-hyun and Park Geun-hye—were made within three months. If Yoon is removed, South Korea will hold a new presidential election within 60 days.

Liberal opposition leader Lee Jae-myung, seen as the frontrunner to succeed Yoon, has called for a swift court ruling and proposed a special council to improve cooperation between the government and parliament. Lee narrowly lost the 2022 presidential election to Yoon and has since been a vocal critic of his administration.

Meanwhile, Kweon Seong-dong, a key figure in Yoon’s People Power Party, dismissed Lee’s proposal, accusing the opposition of overstepping its role.

The impeachment has disrupted South Korea’s politics, strained diplomatic relations, and added uncertainty to efforts aimed at stabilising the country’s faltering economy.
