Key legal question
Whether the daughter/heir was entitled to appeal and whether the repayment could be addressed to her alone.
Extracted holding
As heir of the deceased EL recipient, the appellant was liable for unlawful benefits and had standing to challenge the decision addressed to her alone.
Extracted reasoning
No disclaimer of inheritance was indicated; under EL rules, heirs must repay unlawfully granted benefits, and a decision may validly be addressed only to the heir.
