The high court's ruling upholds the sentence, which includes 8 years for the abuse of one minor and 4 for the other, as well as compensation payments of 45,000 and 15,000 euros, as requested by the Public Prosecutor's Office. The convicted man was acquitted of two counts of continuous exhibition of pornographic material.

The Supreme Court considers the facts proven, which occurred when the paternal grandfather was between 66 and 75 years old and the granddaughters were between 6 and 14 years old. The abuse took place when the man was in charge of the girls, whom he allegedly threatened not to tell their family.

The accused, who ran a canteen in Santa Cruz de Tenerife, argued before the Supreme Court that the victims' statements lacked persistence and that there were no objective indications. He also questioned the parents' testimony as hearsay and that of a witness unrelated to the family, in addition to the inconclusive nature of the psychological expert evidence.

The court's response was that both the High Court of Justice of the Canary Islands and the Provincial Court had "reasonably and with due motivation" upheld the presented evidence, "in accordance with the rules of logic, reason, and the experience of life." The Supreme Court finds no "serious imprecisions, flaws, discrepancies, or breaks in the complainant's account."

Regarding credibility, the court notes that changes in the order of statements or expansions of the narrative do not affect the "coherence and substantial significance of what was narrated," indicating a tendency towards "imaginative fabrication." The minors suffered physical and psychological repercussions, manifested in rebelliousness and difficulties in forming normal relationships.
