G'now juk Hol pajhard was the Klingon law of heredity. According to this law, the son would share in the honors or crimes of his father.

Before his death, Duras made a claim for leadership of the High Council. After his death, his son Toral filed a petition for the leadership. Normally, the request would be granted. However, as Toral had not proven himself in battle, his request was rejected and his father's claim to the leadership died with him. This ruling resulted in the Klingon Civil War of 2367-2368.
