who has authority and priority to act and who is reasonably available to act.
However, if a health care provider is unwilling to comply with a health care decision made by a health care representative, and the declarant's health condition would make transfer of the declarant untenable or unadvisable, this subsection does not prohibit the health care provider from following the health care provider's dispute resolution procedure with the objective of reaching a decision in the best interest of the declarant.
