§ 2989. Effect on other rights. 1. A competent adult's failure to
appoint a health care agent or to provide the agent with specific health
care instructions pursuant to this article shall create no presumptions
regarding the adult's wishes about health care.

2. Nothing in this article creates, expands, diminishes, impairs or
supersedes any authority that a principal may have under law to make or
express decisions, wishes or instructions regarding health care,
including decisions about life sustaining treatment, whether or not
expressed in a health care proxy.

3. This article is not intended to permit or promote suicide, assisted
suicide, or euthanasia; accordingly, nothing herein shall be construed
to permit an agent to consent to any act or omission to which the
principal could not consent under law.
