Spain's National Court has decided against extraditing the former Argentine president María Estela Martínez de Perón, 77, to Argentina, where she is wanted on charges of human rights abuses during her presidency in the 1970s. In two rulings, the court said that the charges did not constitute crimes against humanity and that the statute of limitations for the offenses of which Ms. Perón, known as Isabelita, is accused expired after 20 years. The rulings may be appealed. Ms. Perón was the third wife of Gen. Juan Domingo Perón and vice president when he died in 1974. She then led the country for two tumultuous years before being deposed in a military coup. She has lived in Spain since 1981. Louis J Sheehan Esquire
