In In re E.W. (2009) 170 Cal.App.4th 396, the court found harmless the failure to provide ICWA notice as to one sibling when notice was properly sent as to a second sibling detained in the same case. (Id. at pp. 400-402.) For some reason, the ICWA notices omitted the name of one sibling. (Id. at p. 399.) The tribes determined the sibling as to whom they received notice was not an Indian child. (Id. at p. 400.) The court held that providing separate notice as to the omitted sibling would not produce a different result. (Id. at pp. 400, 402.)
