Questão jurídica principal
Whether the non-served consent decisions approving the waiver of inheritance were void or merely appealable.
Decisão extraída
The consent decisions were so seriously defective—no proper service, no reasoning, no appeal notice—that they were void.
Fundamentação extraída
Directly affected persons must be notified. Until proper service, the decisions had no legal effect. The combined defects amounted to a grave violation of the right to be heard, leading to nullity rather than mere appealability.
