16 Del. C. § 2522: Decision by guardian.

(a) A guardian may refuse to comply with a provision of or revoke the individual’s advance health-care directive only if the court appointing the guardian issues an order expressly permitting the acts taken by the guardian.

(b) Unless a court orders otherwise, a health-care decision made by an agent appointed by an individual subject to guardianship prevails over a decision of the guardian appointed for the individual.
