The Corruption Investigation Office for High-Ranking Officials, which is leading a joint investigation with police and military authorities into the power grab that lasted only a few hours, confirmed it requested the warrant from the Seoul Western District Court. They plan to question Yoon on charges of abuse of authority and orchestrating a rebellion.
Yoon has dodged several requests by the joint investigation team and public prosecutors to appear for questioning and has also blocked searches of his offices.
It's not clear whether the court will grant the warrant or whether Yoon can be compelled to appear for questioning.
Under the country's laws, locations potentially linked to military secrets cannot be seized or searched without the consent of the person in charge, and it's unlikely that Yoon will voluntarily leave his residence if he faces detainment.
Yoon's presidential powers were suspended after the National Assembly voted to impeach him on December 14 over his imposition of martial law that lasted only hours but has triggered weeks of political turmoil, halted high-level diplomacy and rattled financial markets.Â
Yoon's fate now lies with the Constitutional Court, which has begun deliberations on whether to uphold the impeachment and formally remove Yoon from office or reinstate him.
Yoon has defended the martial law decree as a necessary act of governance, describing it as a warning against the liberal opposition Democratic Party, which has been bogging down his agenda with its majority in the parliament.
Parliament voted last week to also impeach Prime Minister Han Duck-soo, who had assumed the role of acting president after Yoon's powers were suspended, over his reluctance to fill three Constitutional Court vacancies ahead of the court's review of Yoon's case.
The country's new interim leader is Deputy Prime Minister Choi Sang-mok, who is also finance minister.
