HRS §327G-9
How guardians must follow mental health care wishes
A guardian must follow the principal's mental health care directive and cannot revoke it without a court order. If there is also an agent, the agent's decision wins unless a court says otherwise. A guardian's decision is valid without court approval unless it goes against the directive.

(b) Absent a court order to the contrary, a mental health care decision of an agent takes precedence over that of a guardian. (c) A mental health care decision made by a guardian for the principal is effective without judicial approval, unless contrary to the principal's preferences or instructions expressed in the advance mental health care directive.
