Seoul: A hearing on the legality of former President Yoon Suk Yeol's arrest will be held later this week, a court said Wednesday, as Yoon fights to regain his freedom a week after being placed in custody over his failed attempt to impose martial law.

According to Yonhap News Agency, the hearing has been scheduled for 10:15 a.m. Friday, the Seoul Central District Court said, shortly after Yoon's lawyers announced he had filed for a review of the legality of his arrest. The petition was submitted to challenge the arrest as "illegal" and "unjust," both substantively and procedurally, the lawyers stated in a press release.

By law, the court is obligated to question the defendant and examine evidence within 48 hours after the request is filed before deciding on the legality of the arrest and whether it should remain in effect. Depending on the outcome, Yoon could be released from the Seoul Detention Center, where he has been held since last Thursday following a court-issued warrant for his arrest over five key charges related to his martial law bid.

Yoon previously underwent a similar process in January after his first arrest. At that time, his detention was deemed legal, but a subsequent request to cancel his arrest was accepted by the court, leading to his release in March.
