Here is the opinion in In re Howard.
Where a respondent’s parental rights have otherwise been properly terminated under Michigan law, but the petitioner and the trial court failed to comply with the ICWA’s notice provision, the proper remedy is to conditionally reverse and remand for resolution of the ICWA notice issue. In re Morris, 491 Mich at 121. If the trial court conclusively determines that ICWA does not apply to the involuntary child custody proceeding—because the children are not Indian children or because the properly noticed tribe does not respond within the allotted time—the trial court’s order terminating parental rights is reinstated. If, however, the trial court concludes that ICWA does apply to the child custody proceeding, the trial court’s order terminating parental rights must be vacated and all proceedings must begin anew in accord with the procedural and substantive requirements of ICWA. In re Morris, 491 Mich at 120-121.
