(1) A directive may be revoked at any time by the declarer, without regard to the declarer's mental state or competency, by any of the following methods:
(a) By being canceled, defaced, obliterated, burned, torn, or otherwise destroyed by the declarer or by some person in the declarer's presence and by the declarer's direction.
(b) By a written revocation of the declarer expressing his or her intent to revoke, signed, and dated by the declarer. Such revocation shall become effective only upon communication to the attending physician by the declarer or by a person acting on behalf of the declarer. The attending physician shall record in the patient's medical record the time and date when the physician received notification of the written revocation.
(c) By a verbal expression by the declarer of his or her intent to revoke the directive. Such revocation shall become effective only upon communication to the attending physician by the declarer or by a person acting on behalf of the declarer. The attending physician shall record in the patient's medical record the time, date, and place of the revocation and the time, date, and place, if different, of when the physician received notification of the revocation.
(d) In the case of a directive that is stored in the health care declarations registry under RCW
70.122.130, by an online method established by the department of health. Failure to use this method of revocation for a directive that is stored in the registry does not invalidate a revocation that is made by another method described under this section.
(2) There shall be no criminal or civil liability on the part of any person for failure to act upon a revocation made pursuant to this section unless that person has actual or constructive knowledge of the revocation except as provided in RCW
70.122.051(4).
(3) If the declarer becomes comatose or is rendered incapable of communicating with the attending physician, the directive shall remain in effect for the duration of the comatose condition or until such time as the declarer's condition renders the declarer able to communicate with the attending physician.
