He is part of the legal team defending the party's dissolution. During the trial, Chuan seemed agitated. When the hearing ended, Chuan stood up as the team of judges left the courtroom. He screamed in pain when sitting.
He was helped from the room and went straight to hospital. He was scheduled to meet with doctors about his back pain in the afternoon.
