In proceedings for involuntary court-ordered admission, the court shall hear and consider all relevant testimony, including, but not limited to, the testimony of examining personnel who participated in the evaluation of the person alleged to be a person in a mental health crisis and the certificates of physicians, certified psychologists or advanced practice registered nurses accompanying the petition, if applicable. The court may consider testimony relating to any past actions of the person alleged to be a person in a mental health crisis if such testimony is probative of the question of whether the person is presently a person in a mental health crisis.
