In re J.M. (2012) 206 Cal.App.4th 375 involved two siblings, ICWA notices were sent containing the name of one sibling but not the other. (Id. at p. 379.) They claimed Indian heritage through the same parent. (Id. at p. 383.) But there was no indication that notice as to the omitted sibling would have contained different information. The Court concluded the inclusion of the omitted sibling in the ICWA notices could not possibly have produced different results. (Ibid.)
