(1) The children or descendants of a person excluded as unworthy shall not be excluded by reason of the unworthiness of their parent or ascendant, whether they succeed in their own right or whether, in order to succeed, they have to stand, under the rule of representation, in the place of the parent or ascendant so excluded.
