Notwithstanding any provision of the general statutes, whenever a final decree of adoption of an Indian child has been vacated or set aside, or the adoptive parents voluntarily consent to the termination of their parental rights to the child, a biological parent or prior Indian custodian of the child may petition for return of custody and the court shall grant such petition unless there is a showing, in a proceeding subject to the provisions of sections 46b-116d to 46b-116i, inclusive, that such return of custody is not in the best interests of the child.
