SGM where the biological father is still alive, but the deceased mother's siblings request guardianship over the child, even though it is clearly seen in Article 345 of the Civil Code that states that if one of the parents dies then the guardianship rights over the minor child automatically fall to his surviving parents. However, the decision handed down by the panel of judges was different in this case, which granted the child's aunt to be his guardian, so this attracted the writer's attention to research this matter more deeply.
