Take a look at Justice Breyer’s concurrence. Last paragraph:
Third, other statutory provisions not now before us may nonetheless prove relevant in cases of this kind. Section 1915(a) grants an adoptive “preference” to “(1) a member of the child’s extended family; (2) other members of the Indian child’s tribe; or (3) other Indian families . . . . in the absence of good cause to the contrary.” Further, §1915(c) allows the “Indian child’s tribe” to “establish a different order of preference by resolution.” Could these provisions allow an absentee father to re-enter the special statutory order of preference with support from the tribe, and subject to a court’s consideration of “good cause?” I raise, but do not here try to answer, the question.
Presumably, the litigation will continue on remand to the South Carolina courts below.
