Nothing in the provisions of sections 46b-116a to 46b-116aa, inclusive, shall be construed to prevent (1) the emergency removal of an Indian child who is a resident of or is domiciled on a reservation, but temporarily located off the reservation, from such Indian child’s parent or Indian custodian, or (2) the emergency placement of such child in a foster home or institution, under applicable state law, in order to prevent imminent physical damage or harm to the child. The Commissioner of Children and Families shall ensure that the emergency removal or placement terminates immediately when such removal or placement is no longer necessary to prevent imminent physical damage or harm to the child and shall expeditiously initiate a child custody proceeding subject to the provisions of sections 46b-116a to 46b-116aa, inclusive, transfer the child to the jurisdiction of the appropriate Indian tribe, or restore the child to the parent or Indian custodian, as may be appropriate.
