Who qualifies as an interested person under the relevant statutes?

The definition of an "interested person" under the relevant statutes is broad and includes various individuals who may have a stake in a particular matter. This encompasses a wide range of individuals and roles that may impact or be affected by decisions made regarding a person's health or estate.

An adult relative or friend of the individual qualifies as an interested person, as they may have personal interest or concern regarding the individual's well-being or decisions affecting their legal rights, such as health care directives or financial matters.

A government official is also considered an interested person because their responsibilities may involve oversight or intervention in matters affecting the individual's health or estate, especially in situations involving guardianship or welfare.

Additionally, a health care agent is included as an interested person since they are designated to make medical decisions on behalf of the individual if they are incapacitated. As such, the health care agent has a direct interest in the medical and health decisions made for the individual.

Therefore, since all these categories—adult relatives or friends, government officials, and health care agents—are recognized as holding legitimate interests in matters pertaining to an individual's legal and health decisions, the answer that encompasses all of these groups is indeed correct.
