9 reparations and payment of the compensation, and that only after complete compliance has been verified would the case be closed. XII 34. On May 10, 1996 the Commission submitted to the Court an application from the minor child Ingrid Carolina Caballero-Martínez, requesting that the Judgment to be issued by the Court "recognize the minor INGRID CAROLINA CABALLERO-MARTINEZ as the daughter of the victim ISIDRO CABALLERO-DELGADO" (capitals in the original). To that end, the attorney submitted documents substantiating the kinship between his client and the victim and describing the moral and material damage she had sustained as a result of her father's disappearance. He also pointed out that the victim had been responsible for his daughter's upkeep, for which purpose "25 percent of his salary and unemployment benefit had been withheld by agreement reached with the child's mother in the Bucaramanga Second Minors Civil Court." 35. At the public hearing held by the Court on September 7, 1996, the Government requested the Commission to refer to the situation of the youth Caballero-Martínez, to which the Commission replied that "the proper course [would be] for the Court to reserve her rights in the event they were substantiated."

In response to that request, on November 28, 1996 the Government submitted a copy of a letter from the National Civil Registry of Colombia stating that the department files "contained no evidence that any certificate of citizenship had ever been issued in the name of Santana-Ortiz María del Carmen or Ortiz Vitelma." The Government also sent the Court a copy of the thirteen existing records relating to María del Carmen Santana. On December 13, 1996 the Commission submitted a copy of a communication it had received from the representatives of the petitioners in the case, declaring that the statements contained in the probatory evidence "conclusively established both María del Carmen Santana's existence and her emotional ties to Mr. Cristóbal Anaya-González." XIV 39. In calculating the compensation for material damage suffered by the relatives of the victims, the Court decided that the amount should be one which, invested at a nominal interest rate, would have a monthly yield equivalent to the amount of the income the victims would have received during their probable lifetime. In this regard, the Court ruled
