Here is the opinion in In re Nery V. From the opinion:
The county court for Hall County, sitting as a juvenile court, terminated the parental rights of Mario V., Sr. (Mario Sr.), and Ida V. to their minor children. Mario Sr. appeals in case No. A-12-629, and Ida appeals in case No. A-12-662. We initially determine that the relinquishments that Ida executed some 3 years before these proceedings are valid and that her attempted revocation of such is of no force and effect. But, because there is no evidence that the Rosebud Sioux Tribe was given proper notice of these termination of parental rights proceedings as required by the Nebraska Indian Child Welfare Act (NICWA), we find that the termination proceedings conducted were invalid and thus that the order of termination in both cases must be vacated. We therefore remand the causes to the juvenile court for further proceedings consistent with our opinion.
