Beside the impeachment process against him, which the Constitutional Court has taken over since the parliament voted for impeachment, two criminal investigations are ongoing. In one of them, the police, the country's anti-corruption unit, and the Defense Ministry's investigation department are cooperating. They have several times tried to serve Yoon with a summons for questioning about the suspicions against him of attempted insurrection and abuse of presidential power.
Refuses to accept
However, the President's office has refused to accept it or sent it back with return receipt, and Yoon did not show up for the scheduled questioning on Wednesday.
Now the investigators are considering requesting an arrest warrant.
The second criminal investigation into the legality of the state of emergency is being conducted by prosecutors. They had requested that Yoon appear for questioning on Sunday, but he did not show up either. Now they have asked him to appear on Saturday.
Is suspended
In the impeachment process, the Constitutional Court has taken over and begun its work after the parliament's decision. The court has up to six months to decide whether Yoon should be permanently removed or reinstated to his post. In the meantime, he is suspended from his office, and the Prime Minister is acting instead.
