"I will fully elaborate my stance at the courtroom," he told reporters as he entered the courthouse, declining to answer any questions asked by reporters.

The court's decision is expected to come late at night or early Wednesday.

The investigation team, led by Independent Counsel Park Young-soo, on Sunday asked the court to issue the writ against Woo on charges of abuse of authority and dereliction of duty.

Prosecutors grilled Woo for nearly 19 hours from Saturday.

He is accused of peddling influence in the government's management of personnel, as well as hindering lawful investigations.

Prosecutors are also looking into whether Woo aided and abetted Choi Soon-sil, President Park's friend of 40 years, in meddling in state affairs. He has been flatly denying any connection with Choi. (Yonhap)
