A durable power of attorney for health care designated under the provisions of § 59-7-2.1 is presumed valid. Another person may rely on the presumption of validity unless the person has actual knowledge that the power was not validly executed or that the power was revoked.
Except as provided in this section, any person who refuses to accept the authority of the agent to exercise a power granted under the durable power of attorney for health care is liable to the principal and to the principal's heirs, assigns, and the personal representative or successor in interest of the principal's estate in the same manner as the person would be liable had the person refused to accept the authority of the principal to act on the principal's own behalf. The person found liable for refusing to accept the authority of an agent is liable for damages and costs, including reasonable attorney's fees.
A person who refuses to accept the authority of an agent to exercise a power granted under a durable power of attorney for health care is not liable pursuant to this section if:
This section does not negate the liability that a person would have to the principal or the agent under another form of power of attorney, under the common law, or otherwise.
