Do the grandchildren of a deceased man inherit from their grandfather's estate if their father died before their grandfather, and the grandfather died before his estate was distributed, given that the grandchildren have paternal uncles?

Grandchildren do not inherit from their grandfather's estate if there are paternal uncles, as the uncle disinherits all grandchildren by scholarly consensus. What is called "obligatory bequest" for grandchildren is a null and void man-made law. It is the grandfather who inherits from the estate of his son who died during his lifetime. The grandfather's share from his son's estate is added to the grandfather's wealth and becomes an inheritance for his legal heirs, among whom his grandchildren are not included. The grandfather or his heirs can waive their right to the inheritance.
