Editor's Notes

Uniform Law: This section is based upon § 1-103 of the Uniform Guardianship and Protective Proceedings Act (1982 Act).

Section 21(h)(1) of D.C. Law 19-169 purported to amend (d)(1) by substituting “developmental disability” for “mental retardation”; as that language does not appear in (d)(1), but does appear in (d)(2), the change has been effected there.

Section 35 of D.C. Law 19-169 provided that no provision of the act shall impair any right or obligation existing under law.
