Laura made an Advance Directive (AD) to the effect that, should she become severely mentally impaired, she would not wish to receive life-sustaining medical treatment. 5 years later, she suffered severe head injuries in a sporting event and was rushed to hospital. Though the doctors there managed to save her life, she is left brain damaged to the extent that she can no longer communicate and needs 24/7 living assistance. Nevertheless, she continues to derive simple pleasures from her existence. Laura's husband, Samuel believes that his wife would have wanted to continue living. They met 3 years ago and married last year.

Advise the hospital on the lawfulness of its decisions (in which it is not supported by Laura's husband, Samuel) to discontinue the treatment.
