54. Advance medical directives may be revoked at any time by the person concerned by means of the form prescribed by the Minister.
Such directives may only be changed by writing new ones by one of the methods specified in the first paragraph of section 52. The new directives replace any previous ones.
Despite the first and second paragraphs, in emergency cases, if a person capable of giving consent to care verbally expresses wishes different from those in their advance medical directives, this entails the revocation of the directives.
